Description

把持工具、および、把持工具の使用方法How to use the gripping tool and the gripping tool
　本発明は、把持工具、および、把持工具の使用方法に関する。 The present invention relates to a gripping tool and a method of using the gripping tool.
　把持対象物を把持する把持工具が知られている。 A gripping tool for gripping an object to be gripped is known.
　関連する技術として、特許文献１には、間接活線把持工具が開示されている。特許文献１に記載の間接活線把持工具は、把持機構と、絶縁操作棒と、噛合部材と、ロック機構とを備える。把持機構は、固定把持部と可動把持部とを有する。絶縁操作棒は、操作棒本体と、操作棒本体の内側に配置された軸芯側部材とを有する。操作棒本体は、軸芯側部材に対して軸方向に沿ってスライド可能である。 As a related technique, Patent Document 1 discloses an indirect hot-line gripping tool. The indirect hot-line gripping tool described in Patent Document 1 includes a gripping mechanism, an insulating operation rod, a meshing member, and a locking mechanism. The gripping mechanism has a fixed gripping portion and a movable gripping portion. The insulating operation rod has an operation rod main body and a shaft core side member arranged inside the operation rod main body. The operation rod body can slide along the axial direction with respect to the shaft core side member.
　特許文献１に記載の間接活線把持工具では、操作棒本体を把持機構側にスライドさせると、ロック機構が作動する。ロック機構の作動状態では、可動把持部が固定把持部から離れるように絶縁操作棒を回転させることが防止される。操作棒本体を把持機構から離れる方向にスライドさせると、ロック機構のロックが解除される。その結果、可動把持部が固定把持部から離れるように絶縁操作棒を回転させることが可能になる。 In the indirect hot-line gripping tool described in Patent Document 1, the lock mechanism is activated when the operation rod main body is slid toward the gripping mechanism side. In the operating state of the lock mechanism, it is prevented from rotating the insulating operation rod so that the movable grip portion is separated from the fixed grip portion. When the operation rod body is slid away from the gripping mechanism, the lock mechanism is unlocked. As a result, it becomes possible to rotate the insulating operation rod so that the movable grip portion is separated from the fixed grip portion.
　また、特許文献２には、遠隔操作用把持工具が開示されている。特許文献２に記載の遠隔操作用把持工具は、固定側把持腕部と、可動側把持腕部と、球状の支点部を有する受圧部材と、支点部を支点として可動側把持腕部を回動させる角度調節機構とを備える。 Further, Patent Document 2 discloses a gripping tool for remote control. The gripping tool for remote operation described in Patent Document 2 rotates the movable side gripping arm portion with the fixed side gripping arm portion, the movable side gripping arm portion, the pressure receiving member having a spherical fulcrum portion, and the fulcrum portion as a fulcrum. It is equipped with an angle adjustment mechanism.

The first grip portion 11 has a first grip surface 110 that comes into contact with the gripping object W. In the example described in FIG. 1, the first gripping surface 110 has a first surface 111 that can come into contact with the gripping object W and a second surface 112 that can come into contact with the gripping object W. Further, an obtuse angle (an angle larger than 90 degrees) is formed by the first surface 111 and the second surface 112. However, the shape of the first gripping surface 110 is not limited to the example shown in FIG. 1, and is arbitrary. For example, the first gripping surface 110 may be a concave curved surface. When the gripping object W gripped by the gripping tool 1A is an object that passes an electric current such as an electric wire, an insulating layer RB (for example, an insulating rubber layer or an insulating resin layer) is arranged on the surface of the first gripping portion 11. It may have been done.
　第１部材１０は、１つの部品によって構成されてもよいし、複数の部品のアセンブリによって構成されてもよい。 The first member 10 may be composed of one component or an assembly of a plurality of components.
　図１に記載の例では、第２部材２０は、第２把持部２１を含む。第２把持部２１は、把持対象物Ｗに接触する第２把持面２１０を有する。図１に記載の例では、第２把持面２１０は、把持対象物Ｗに接触可能な第３面２１３と、把持対象物Ｗに接触可能な第４面２１４とを有する。また、第３面２１３と第４面２１４とによって鈍角（９０度より大きな角）が形成されている。ただし、第２把持面２１０の形状は、図１に記載の例に限定されず任意である。例えば、第２把持面２１０は、凹曲面であってもよい。把持工具１Ａによって把持される把持対象物Ｗが電線等のように電流をとおす物体である場合、第２把持部２１の表面には絶縁層ＲＢ（例えば、絶縁ゴム層または絶縁樹脂層）が配置されていてもよい。 In the example described in FIG. 1, the second member 20 includes the second grip portion 21. The second grip portion 21 has a second grip surface 210 that comes into contact with the gripping object W. In the example described in FIG. 1, the second gripping surface 210 has a third surface 213 that can come into contact with the gripping object W and a fourth surface 214 that can come into contact with the gripping object W. Further, an obtuse angle (an angle larger than 90 degrees) is formed by the third surface 213 and the fourth surface 214. However, the shape of the second gripping surface 210 is not limited to the example shown in FIG. 1, and is arbitrary. For example, the second gripping surface 210 may be a concave curved surface. When the gripping object W gripped by the gripping tool 1A is an object that passes an electric current such as an electric wire, an insulating layer RB (for example, an insulating rubber layer or an insulating resin layer) is arranged on the surface of the second gripping portion 21. It may have been done.
　第２部材２０は、１つの部品によって構成されてもよいし、複数の部品のアセンブリによって構成されてもよい。 The second member 20 may be composed of one component or an assembly of a plurality of components.
　第３部材３０は、第１把持部１１と第２把持部２１との間の間隔が縮小するように第２部材２０に力を伝達可能な部材である。図１に記載の例では、第３部材３０は、第２部材２０に接触する接触部３１を備える。接触部３１は、例えば、第２部材２０の被押圧部２２を押圧可能な押圧面３１ａを含む。押圧面３１ａは、例えば、第１方向ＤＲ１（換言すれば、第３部材３０の移動方向）に対して傾斜した傾斜面である。図１に記載の例では、第２部材２０が押圧面３１ａによって押圧されることにより、第１把持部１１と第２把持部２１との間の間隔が縮小される。詳細については後述される。 The third member 30 is a member capable of transmitting a force to the second member 20 so that the distance between the first grip portion 11 and the second grip portion 21 is reduced. In the example shown in FIG. 1, the third member 30 includes a contact portion 31 in contact with the second member 20. The contact portion 31 includes, for example, a pressing surface 31a capable of pressing the pressed portion 22 of the second member 20. The pressing surface 31a is, for example, an inclined surface inclined with respect to the first direction DR1 (in other words, the moving direction of the third member 30). In the example shown in FIG. 1, when the second member 20 is pressed by the pressing surface 31a, the distance between the first grip portion 11 and the second grip portion 21 is reduced. Details will be described later.
　第３部材３０は、１つの部品によって構成されてもよいし、複数の部品のアセンブリによって構成されてもよい。図１に記載の例では、第３部材３０は、第４部材４０に螺合するネジ棒３３を備える。図１に記載の例では、ネジ棒３３は、その外周面に雄ネジ部３３ｍを有する。 The third member 30 may be composed of one component or an assembly of a plurality of components. In the example shown in FIG. 1, the third member 30 includes a screw rod 33 screwed to the fourth member 40. In the example shown in FIG. 1, the screw rod 33 has a male screw portion 33 m on its outer peripheral surface.
　ロック機構Ｍは、第１把持部１１と第２把持部２１との間の間隔が拡大することを防ぐロック状態と、第１把持部１１と第２把持部２１との間の間隔が拡大することを許容するロック解除状態とを切り替える機構である。図２に記載の例では、ロック機構Ｍは、第１係合部Ｍ１と、第２係合部Ｍ２とを含む。第１係合部Ｍ１と第２係合部Ｍ２とが係合した状態がロック状態に対応し、第１係合部Ｍ１と第２係合部Ｍ２との間の係合が解除された状態がロック解除状態に対応する。詳細については後述される。 The lock mechanism M has a locked state that prevents the distance between the first grip portion 11 and the second grip portion 21 from increasing, and the lock mechanism M increases the distance between the first grip portion 11 and the second grip portion 21. It is a mechanism to switch between the unlocked state and the unlocked state. In the example shown in FIG. 2, the locking mechanism M includes a first engaging portion M1 and a second engaging portion M2. The state in which the first engaging portion M1 and the second engaging portion M2 are engaged corresponds to the locked state, and the state in which the engagement between the first engaging portion M1 and the second engaging portion M2 is released. Corresponds to the unlocked state. Details will be described later.
　図３に記載の例では、第４部材４０は、第３部材３０（より具体的には、ネジ棒３３）に螺合している。より具体的には、第４部材４０は、第３部材３０の雄ネジ部３３ｍに螺合する雌ネジ部４３ｆを備える。 In the example shown in FIG. 3, the fourth member 40 is screwed into the third member 30 (more specifically, the screw rod 33). More specifically, the fourth member 40 includes a female screw portion 43f screwed into the male screw portion 33m of the third member 30.
　図３に記載の例では、第４部材４０が第３部材３０に対して第１回転方向Ｒ１に相対回転すると、第３部材３０は、第４部材４０に対して第１方向ＤＲ１に相対移動する。例えば、第４部材４０が第３部材３０に対して第１回転方向Ｒ１に相対回転すると、第３部材３０の接触部３１が第２部材２０に力を伝達する。より具体的には、第４部材４０が第３部材３０に対して第１回転方向Ｒ１に相対回転すると、第３部材３０の押圧面３１ａが第２部材２０の被押圧部２２を押圧する。こうして、第１把持部１１と第２把持部２１との間の間隔が縮小される。 In the example shown in FIG. 3, when the fourth member 40 rotates relative to the third member 30 in the first rotation direction R1, the third member 30 moves relative to the fourth member 40 in the first direction DR1. do. For example, when the fourth member 40 rotates relative to the third member 30 in the first rotation direction R1, the contact portion 31 of the third member 30 transmits a force to the second member 20. More specifically, when the fourth member 40 rotates relative to the third member 30 in the first rotation direction R1, the pressing surface 31a of the third member 30 presses the pressed portion 22 of the second member 20. In this way, the distance between the first grip portion 11 and the second grip portion 21 is reduced.
　また、図４に記載の例では、第４部材４０は、ロック機構Ｍの少なくとも一部を構成する。より具体的には、第４部材４０は、第１係合部Ｍ１を有する。ロック機構Ｍがロック状態にあるとき、第４部材４０は、第３部材３０に対して第１回転方向Ｒ１とは反対の第２回転方向Ｒ２に相対回転することができない。よって、ロック機構Ｍがロック状態にあるとき、第１把持部１１と第２把持部２１との間の間隔が拡大されることが防止される。詳細については後述される。 Further, in the example shown in FIG. 4, the fourth member 40 constitutes at least a part of the lock mechanism M. More specifically, the fourth member 40 has a first engaging portion M1. When the lock mechanism M is in the locked state, the fourth member 40 cannot rotate relative to the third member 30 in the second rotation direction R2 opposite to the first rotation direction R1. Therefore, when the lock mechanism M is in the locked state, it is possible to prevent the distance between the first grip portion 11 and the second grip portion 21 from being expanded. Details will be described later.
　第４部材４０は、１つの部品によって構成されてもよいし、複数の部品のアセンブリによって構成されてもよい。 The fourth member 40 may be composed of one component or an assembly of a plurality of components.
　図３および図４に記載の例では、操作部材５０が操作されることにより、第１把持部１１と第２把持部２１との間の間隔が変更される。操作部材５０は、第１把持部１１と第２把持部２１との間の間隔を変更する第１操作部材であると言うこともできる。 In the examples shown in FIGS. 3 and 4, the distance between the first grip portion 11 and the second grip portion 21 is changed by operating the operation member 50. It can also be said that the operation member 50 is a first operation member that changes the distance between the first grip portion 11 and the second grip portion 21.
　図３に記載の例では、操作部材５０は、第４部材４０に螺合している。より具体的には、操作部材５０は、第４部材４０の雄ネジ部４３ｍに螺合する雌ネジ部５３ｆを備える。 In the example shown in FIG. 3, the operating member 50 is screwed into the fourth member 40. More specifically, the operating member 50 includes a female screw portion 53f screwed into the male screw portion 43m of the fourth member 40.
　図３に記載の例では、操作部材５０が第４部材４０とともに、第３部材３０に対して、第１回転方向Ｒ１に相対回転すると、第１把持部１１と第２把持部２１との間の間隔が縮小される。他方、操作部材５０が第４部材４０とともに、第３部材３０に対して、第２回転方向Ｒ２に相対回転すると、第１把持部１１と第２把持部２１との間の間隔が拡大される。 In the example shown in FIG. 3, when the operating member 50 and the fourth member 40 rotate relative to the third member 30 in the first rotation direction R1, between the first grip portion 11 and the second grip portion 21. Interval is reduced. On the other hand, when the operating member 50 and the fourth member 40 rotate relative to the third member 30 in the second rotation direction R2, the distance between the first grip portion 11 and the second grip portion 21 is increased. ..
　操作部材５０は、１つの部品によって構成されてもよいし、複数の部品のアセンブリによって構成されてもよい。 The operation member 50 may be composed of one component or an assembly of a plurality of components.
　第１の実施形態における把持工具１Ａでは、第４部材４０が、第３部材３０に螺合するとともに、操作部材５０に螺合している。このため、第４部材４０を第３部材３０に対して相対回転させることができ、第４部材４０を操作部材５０に対して相対回転させることもできる。例えば、第４部材４０を第３部材３０に対して相対回転させることにより、第３部材３０を第１方向ＤＲ１（または、第２方向ＤＲ２）に移動させることができる。また、ロック機構Ｍの少なくとも一部を構成する第４部材４０を操作部材５０に対して相対回転させることにより、ロック機構Ｍの状態を、ロック状態（図４を参照。）とロック解除状態（図３を参照。）との間で切り替えることができる。 In the gripping tool 1A in the first embodiment, the fourth member 40 is screwed into the third member 30 and also into the operating member 50. Therefore, the fourth member 40 can be rotated relative to the third member 30, and the fourth member 40 can be rotated relative to the operating member 50. For example, by rotating the fourth member 40 relative to the third member 30, the third member 30 can be moved to the first direction DR1 (or the second direction DR2). Further, by rotating the fourth member 40, which constitutes at least a part of the lock mechanism M, relative to the operation member 50, the state of the lock mechanism M can be changed into a locked state (see FIG. 4) and an unlocked state (see FIG. 4). It can be switched between (see FIG. 3) and.
　以上のとおり、第１の実施形態では、簡易な操作で、ロック状態とロック解除状態とを切り替え可能な把持工具１Ａが提供される。 As described above, in the first embodiment, the gripping tool 1A capable of switching between the locked state and the unlocked state is provided by a simple operation.
　続いて、図１乃至図６を参照して、第１の実施形態における把持工具１Ａにおいて採用可能な任意付加的な構成について説明する。 Subsequently, with reference to FIGS. 1 to 6, an optional additional configuration that can be adopted in the gripping tool 1A in the first embodiment will be described.
（把持工具１Ａの操作と、ロック機構Ｍの動作）
　図３に記載の例では、操作部材５０が第１回転方向Ｒ１に回転されると、第１把持部１１と第２把持部２１との間の間隔が縮小され、操作部材５０が第２回転方向Ｒ２に回転されると、第１把持部１１と第２把持部２１との間の間隔が拡大する。 (Operation of gripping tool 1A and operation of lock mechanism M)
In the example shown in FIG. 3, when the operating member 50 is rotated in the first rotation direction R1, the distance between the first grip portion 11 and the second grip portion 21 is reduced, and the operating member 50 is rotated in the second rotation. When rotated in the direction R2, the distance between the first grip portion 11 and the second grip portion 21 increases.
　図３に記載の例では、操作部材５０は、第４部材４０と螺合している。このため、操作部材５０が第４部材４０に対して相対回転すると、操作部材５０は、第４部材４０の長手軸方向に沿って、第４部材４０に対して相対移動する。 In the example shown in FIG. 3, the operating member 50 is screwed with the fourth member 40. Therefore, when the operating member 50 rotates relative to the fourth member 40, the operating member 50 moves relative to the fourth member 40 along the longitudinal axis direction of the fourth member 40.
　また、図３に記載の例では、第３部材３０は、第４部材４０と螺合している。このため、操作部材５０が第４部材４０と共に、第３部材３０に対して相対回転すると、第３部材３０は、第４部材４０の長手軸方向に沿って、第４部材４０に対して相対移動する。 Further, in the example shown in FIG. 3, the third member 30 is screwed with the fourth member 40. Therefore, when the operating member 50 rotates relative to the third member 30 together with the fourth member 40, the third member 30 is relative to the fourth member 40 along the longitudinal axis direction of the fourth member 40. Moving.
　図３に記載の例では、第４部材４０は、第４部材４０を回転可能に支持する第４部材支持部Ｂに対して、第１方向ＤＲ１に平行な方向に相対移動することができない。このため、第４部材４０を基準として見た場合、操作部材５０が第４部材４０に対して相対回転すると、操作部材５０は、第１方向ＤＲ１に平行な方向に移動することとなる。また、第４部材４０を基準として見た場合、操作部材５０が第４部材４０と共に、第３部材３０に対して相対回転すると、第３部材３０は、第１方向ＤＲ１に平行な方向に移動することとなる。 In the example described in FIG. 3, the fourth member 40 cannot move relative to the fourth member support portion B that rotatably supports the fourth member 40 in a direction parallel to the first direction DR1. Therefore, when viewed with reference to the fourth member 40, when the operating member 50 rotates relative to the fourth member 40, the operating member 50 moves in a direction parallel to the first direction DR1. Further, when the operating member 50 is rotated relative to the third member 30 together with the fourth member 40 when viewed with the fourth member 40 as a reference, the third member 30 moves in a direction parallel to the first direction DR1. Will be done.
　ロック機構Ｍは、第１把持部１１と第２把持部２１との間の間隔が拡大することを防ぐロック状態と、第１把持部１１と第２把持部２１との間の間隔が拡大することを許容するロック解除状態とを切り替える機構である。なお、ロック状態は、実質的に、第１把持部１１と第２把持部２１との間の間隔を拡大することができない状態を意味する。よって、ロック機構Ｍがロック状態である場合、把持対象物Ｗ（必要であれば、図２を参照。）が把持工具１Ａから脱落することが防止される。他方、ロック解除状態は、第１把持部１１と第２把持部２１との間の間隔を実質的に拡大することができる状態を意味する。よって、ロック解除状態において、第１把持部１１と第２把持部２１との間の間隔が拡大されることにより、把持対象物Ｗを把持工具１Ａから取り外すことができる。 The lock mechanism M has a locked state that prevents the distance between the first grip portion 11 and the second grip portion 21 from increasing, and the lock mechanism M increases the distance between the first grip portion 11 and the second grip portion 21. It is a mechanism to switch between the unlocked state and the unlocked state. The locked state means a state in which the distance between the first grip portion 11 and the second grip portion 21 cannot be substantially increased. Therefore, when the lock mechanism M is in the locked state, the gripping object W (see FIG. 2 if necessary) is prevented from falling off from the gripping tool 1A. On the other hand, the unlocked state means a state in which the distance between the first grip portion 11 and the second grip portion 21 can be substantially increased. Therefore, in the unlocked state, the gap between the first grip portion 11 and the second grip portion 21 is increased, so that the gripping object W can be removed from the grip tool 1A.
　図３に記載の例では、ロック機構Ｍは、第４部材４０に設けられた第１係合部Ｍ１を含む。第１係合部Ｍ１が第４部材４０以外の部材（例えば、第２係合部Ｍ２）と係合することにより、ロック機構Ｍがロック状態となる。なお、ロック状態では、第１把持部１１と第２把持部２１との間の間隔が拡大することは防止されているが、第１把持部１１と第２把持部２１との間の間隔が縮小することは許容されてもよい。代替的に、ロック状態において、第１把持部１１と第２把持部２１との間の間隔が拡大することが防止されるのに加えて、第１把持部１１と第２把持部２１との間の間隔が縮小することが防止されてもよい。 In the example shown in FIG. 3, the lock mechanism M includes a first engaging portion M1 provided on the fourth member 40. When the first engaging portion M1 engages with a member other than the fourth member 40 (for example, the second engaging portion M2), the lock mechanism M is locked. In the locked state, the distance between the first grip portion 11 and the second grip portion 21 is prevented from increasing, but the distance between the first grip portion 11 and the second grip portion 21 is increased. It may be acceptable to shrink. Alternatively, in the locked state, in addition to preventing the distance between the first grip portion 11 and the second grip portion 21 from increasing, the first grip portion 11 and the second grip portion 21 It may be prevented that the interval between them is reduced.
　図３に記載の例では、操作部材５０が、第４部材４０の長手軸方向（換言すれば、第１方向ＤＲ１に平行な方向）に、第４部材４０に対して相対移動することにより、ロック状態とロック解除状態との切り替えが行われる。詳細については後述される。また、図３に記載の例では、第３部材３０が、第４部材４０の長手軸方向（換言すれば、第１方向ＤＲ１に平行な方向）に、第４部材４０に対して相対移動することにより、第１把持部１１と第２把持部２１との間の間隔が変化する。 In the example shown in FIG. 3, the operating member 50 moves relative to the fourth member 40 in the longitudinal axis direction of the fourth member 40 (in other words, the direction parallel to the first direction DR1). Switching between the locked state and the unlocked state is performed. Details will be described later. Further, in the example shown in FIG. 3, the third member 30 moves relative to the fourth member 40 in the longitudinal axis direction of the fourth member 40 (in other words, the direction parallel to the first direction DR1). As a result, the distance between the first grip portion 11 and the second grip portion 21 changes.
　図３に記載の例では、第４部材４０が、操作部材５０に螺合するとともに、第３部材３０に螺合している。このため、操作部材５０を回転させるだけで、上述のロック状態とロック解除状態との切り替えを行うことができ、かつ、第１把持部１１と第２把持部２１との間の間隔を変化させることができる。 In the example shown in FIG. 3, the fourth member 40 is screwed into the operating member 50 and is screwed into the third member 30. Therefore, it is possible to switch between the above-mentioned locked state and the unlocked state simply by rotating the operating member 50, and the distance between the first grip portion 11 and the second grip portion 21 is changed. be able to.
　第１把持部１１と第２把持部２１との間に把持対象物Ｗを配置した後、操作部材５０を第１回転方向Ｒ１に回転させることを想定する。図３に示される状態において、操作部材５０を第１回転方向Ｒ１に回転させると、操作部材５０が第４部材４０と共に、第１回転方向Ｒ１に回転する。その結果、第４部材４０に螺合する第３部材３０が第１方向ＤＲ１に移動する。また、第３部材３０が第１方向ＤＲ１に移動することにより、第３部材３０は、第２把持部２１を有する第２部材２０に力を伝達する。こうして、第１把持部１１と第２把持部２１との間の間隔が縮小され、第１把持部１１と第２把持部２１とによって把持対象物Ｗが把持される。 It is assumed that the operation member 50 is rotated in the first rotation direction R1 after the gripping object W is arranged between the first grip portion 11 and the second grip portion 21. In the state shown in FIG. 3, when the operating member 50 is rotated in the first rotation direction R1, the operating member 50 rotates in the first rotation direction R1 together with the fourth member 40. As a result, the third member 30 screwed to the fourth member 40 moves to the first direction DR1. Further, as the third member 30 moves in the first direction DR1, the third member 30 transmits a force to the second member 20 having the second grip portion 21. In this way, the distance between the first grip portion 11 and the second grip portion 21 is reduced, and the gripping object W is gripped by the first grip portion 11 and the second grip portion 21.
　第１把持部１１と第２把持部２１とによって把持対象物Ｗが把持された後に、更に操作部材５０を第１回転方向Ｒ１に回転させることを想定する。この場合、第３部材３０の移動が制限されるため、第４部材４０に対して第３部材３０が相対回転する代わりに、第４部材４０に対して操作部材５０が相対回転する。換言すれば、第１把持部１１と第２把持部２１とによって把持対象物Ｗが把持された後に、更に操作部材５０を第１回転方向Ｒ１に回転させると、操作部材５０が第４部材４０に対して相対回転し、操作部材５０が第２方向ＤＲ２に移動する。その結果、操作部材５０に設けられた押圧部５６が、進出位置（図３を参照。）から退避位置（図４を参照。）に移動し、ロック機構Ｍが、ロック解除状態からロック状態（第１係合部Ｍ１が第２係合部Ｍ２等の他の部材と係合した状態）になる。 It is assumed that the operation member 50 is further rotated in the first rotation direction R1 after the gripping object W is gripped by the first grip portion 11 and the second grip portion 21. In this case, since the movement of the third member 30 is restricted, the operation member 50 rotates relative to the fourth member 40 instead of rotating relative to the fourth member 40. In other words, after the gripping object W is gripped by the first gripping portion 11 and the second gripping portion 21, when the operating member 50 is further rotated in the first rotation direction R1, the operating member 50 becomes the fourth member 40. The operating member 50 moves relative to the second direction DR2. As a result, the pressing portion 56 provided on the operating member 50 moves from the advanced position (see FIG. 3) to the retracted position (see FIG. 4), and the lock mechanism M moves from the unlocked state to the locked state (see FIG. 4). The first engaging portion M1 is engaged with another member such as the second engaging portion M2).
　上述のとおり、図３および図４に記載の例では、操作部材５０を第１回転方向Ｒ１に回転させることにより、第１把持部１１と第２把持部２１との間の間隔の縮小、および、ロック解除状態からロック状態への切り替えの両方が実行されるように構成されている。このため、操作部材５０を第１回転方向Ｒ１に回転させるだけで、把持対象物Ｗの把持と、ロック状態への切り替えとを実行することができる。 As described above, in the examples shown in FIGS. 3 and 4, by rotating the operating member 50 in the first rotation direction R1, the distance between the first grip portion 11 and the second grip portion 21 is reduced, and the distance between the first grip portion 11 and the second grip portion 21 is reduced. , It is configured to perform both switching from the unlocked state to the locked state. Therefore, it is possible to grip the gripping object W and switch to the locked state simply by rotating the operating member 50 in the first rotation direction R1.
　続いて、第１把持部１１と第２把持部２１とによって把持対象物Ｗが把持された後、操作部材５０を第２回転方向Ｒ２に回転させることを想定する。なお、第２回転方向Ｒ２は、第１回転方向Ｒ１とは反対の方向である。 Subsequently, it is assumed that the operation member 50 is rotated in the second rotation direction R2 after the gripping object W is gripped by the first grip portion 11 and the second grip portion 21. The second rotation direction R2 is the opposite direction to the first rotation direction R1.
　図４に示される状態において、操作部材５０を第２回転方向Ｒ２に回転させると、操作部材５０が第４部材４０に対して相対回転し、操作部材５０が第１方向ＤＲ１に移動する。その結果、操作部材５０に設けられた押圧部５６が、退避位置（図４を参照。）から進出位置（図３を参照。）に移動し、ロック機構Ｍが、ロック状態からロック解除状態になる。より具体的には、押圧部５６が第２係合部Ｍ２を押圧することにより、ロック機構Ｍの状態が、ロック状態からロック解除状態に切り替えられる。 In the state shown in FIG. 4, when the operating member 50 is rotated in the second rotation direction R2, the operating member 50 rotates relative to the fourth member 40, and the operating member 50 moves in the first direction DR1. As a result, the pressing portion 56 provided on the operating member 50 moves from the retracted position (see FIG. 4) to the advanced position (see FIG. 3), and the lock mechanism M changes from the locked state to the unlocked state. Become. More specifically, when the pressing portion 56 presses the second engaging portion M2, the state of the lock mechanism M is switched from the locked state to the unlocked state.
　なお、本実施形態あるいは後述の実施形態において、操作部材５０が第２回転方向Ｒ２に所定角度（例えば、所定角度は、３６０度以上１０８０度以下の任意の角度である。）回転するまではロック状態が維持されることが好ましい。また、操作部材５０が第２回転方向Ｒ２に所定角度以上回転すると、ロック状態からロック解除状態への切り替えが行われることが好ましい。この場合、作業者が、誤って操作部材５０を第２回転方向Ｒ２に回転させた場合であっても、直ちにロックが解除されることがない。よって、作業者および／または作業者の周囲にいる者の安全が確保される。 In this embodiment or the embodiment described later, the operation member 50 is locked until it rotates in the second rotation direction R2 by a predetermined angle (for example, the predetermined angle is an arbitrary angle of 360 degrees or more and 1080 degrees or less). It is preferable that the state is maintained. Further, when the operating member 50 rotates in the second rotation direction R2 by a predetermined angle or more, it is preferable that the locked state is switched to the unlocked state. In this case, even if the operator mistakenly rotates the operating member 50 in the second rotation direction R2, the lock is not immediately released. Therefore, the safety of the worker and / or those around the worker is ensured.
　ロック機構Ｍが、ロック状態からロック解除状態になった後、更に操作部材５０を第２回転方向Ｒ２に回転させることを想定する。操作部材５０を第２回転方向Ｒ２に回転させると、操作部材５０が第４部材４０と共に、第２回転方向Ｒ２に回転する。その結果、第４部材４０に螺合する第３部材３０が第２方向ＤＲ２に移動する。こうして、第１把持部１１および第２把持部２１による把持対象物Ｗの把持が解除される。 It is assumed that the lock mechanism M further rotates the operating member 50 in the second rotation direction R2 after changing from the locked state to the unlocked state. When the operating member 50 is rotated in the second rotation direction R2, the operating member 50 rotates together with the fourth member 40 in the second rotation direction R2. As a result, the third member 30 screwed to the fourth member 40 moves to the second direction DR2. In this way, the gripping object W is released from being gripped by the first gripping portion 11 and the second gripping portion 21.
　上述のとおり、図３および図４に記載の例では、操作部材５０を第２回転方向Ｒ２に所定角度以上回転させることにより、ロック状態からロック解除状態への切り替え、および、第１把持部１１および第２把持部２１による把持対象物Ｗの把持解除の両方が実行される。このため、操作部材５０を第２回転方向Ｒ２に回転させるだけで、ロック解除状態への切り替えと、把持対象物Ｗの把持解除とを実行することができる。 As described above, in the examples shown in FIGS. 3 and 4, the operating member 50 is rotated in the second rotation direction R2 by a predetermined angle or more to switch from the locked state to the unlocked state, and the first grip portion 11 And the gripping release of the gripping object W by the second gripping portion 21 is executed. Therefore, it is possible to switch to the unlocked state and release the gripping object W by simply rotating the operating member 50 in the second rotation direction R2.
（ロック機構Ｍの一例）
　図２乃至図４を参照して、ロック機構Ｍの一例について説明する。 (Example of lock mechanism M)
An example of the lock mechanism M will be described with reference to FIGS. 2 to 4.
　図２に記載の例では、ロック機構Ｍは、第４部材４０に設けられた第１係合部Ｍ１と、第４部材支持部Ｂに設けられた第２係合部Ｍ２とを含む。図２に記載の例では、第４部材支持部Ｂは、第１部材１０の一部を構成する構成要素である。 In the example described in FIG. 2, the lock mechanism M includes a first engaging portion M1 provided on the fourth member 40 and a second engaging portion M2 provided on the fourth member support portion B. In the example shown in FIG. 2, the fourth member support portion B is a component that constitutes a part of the first member 10.
　図２に記載の例では、第１係合部Ｍ１は、環状に配置された複数の歯４５ａを含み、第２係合部Ｍ２は、複数の歯４５ａのうちの何れかに係合可能な突出部１５ａ（より具体的には、爪部）を含む。図２に記載の例では、第１係合部Ｍ１が複数の歯４５ａを備え、第２係合部Ｍ２が少なくとも１つの突出部１５ａを備える。代替的に、第１係合部Ｍ１が少なくとも１つの突出部を備え、第２係合部Ｍ２が複数の歯を備えるようにしてもよい。更に代替的に、第１係合部Ｍ１および第２係合部Ｍ２の各々が、複数の歯を備えるようにしてもよい。 In the example shown in FIG. 2, the first engaging portion M1 includes a plurality of teeth 45a arranged in an annular shape, and the second engaging portion M2 can engage with any one of the plurality of teeth 45a. A protruding portion 15a (more specifically, a claw portion) is included. In the example shown in FIG. 2, the first engaging portion M1 includes a plurality of teeth 45a, and the second engaging portion M2 includes at least one protruding portion 15a. Alternatively, the first engaging portion M1 may include at least one protrusion and the second engaging portion M2 may include a plurality of teeth. Further alternative, each of the first engaging portion M1 and the second engaging portion M2 may be provided with a plurality of teeth.
　図４に記載の例では、第１係合部Ｍ１と第２係合部Ｍ２とが係合した状態で、第４部材４０は、第４部材支持部Ｂに対して第２回転方向Ｒ２に相対回転することができない。また、第４部材４０を第２回転方向Ｒ２に回転させることができないため、第２部材２０に力を伝達する第３部材３０を第２方向ＤＲ２に移動させることもできない。以上のとおり、第１係合部Ｍ１と第２係合部Ｍ２とが係合した状態にあるときには（換言すれば、ロック機構Ｍがロック状態にあるときには）、第４部材４０は第２回転方向Ｒ２に回転できず、把持対象物Ｗの把持を解除する方向に、第３部材３０および第２部材２０を移動させることもできない。 In the example shown in FIG. 4, the fourth member 40 is in the second rotation direction R2 with respect to the fourth member support portion B in a state where the first engaging portion M1 and the second engaging portion M2 are engaged. Cannot rotate relative to each other. Further, since the fourth member 40 cannot be rotated in the second rotation direction R2, the third member 30 that transmits the force to the second member 20 cannot be moved to the second direction DR2. As described above, when the first engaging portion M1 and the second engaging portion M2 are in the engaged state (in other words, when the locking mechanism M is in the locked state), the fourth member 40 rotates second. It cannot rotate in the direction R2, and the third member 30 and the second member 20 cannot be moved in the direction in which the gripping object W is released from gripping.
　他方、図２に記載の例では、第１係合部Ｍ１と第２係合部Ｍ２とが係合した状態で、第４部材４０は、第４部材支持部Ｂに対して第１回転方向Ｒ１に相対回転することができる。第４部材４０を第４部材支持部Ｂに対して第１回転方向Ｒ１に相対回転すると、第２係合部Ｍ２が、第１係合部Ｍ１の少なくとも１つの歯４５ａを乗り越える。第２係合部Ｍ２が、第１係合部Ｍ１の少なくとも１つの歯４５ａを乗り越えた後、第２係合部Ｍ２は、第１係合部Ｍ１の他の歯と係合することとなる。代替的に、第１係合部Ｍ１および／または第２係合部Ｍ２の形状を設計変更することにより、第１係合部Ｍ１と第２係合部Ｍ２とが係合した状態では、第４部材４０が、第４部材支持部Ｂに対して、第１回転方向Ｒ１および第２回転方向Ｒ２の両方向に、相対回転することができないようにしてもよい。 On the other hand, in the example shown in FIG. 2, the fourth member 40 is in the first rotation direction with respect to the fourth member support portion B in a state where the first engaging portion M1 and the second engaging portion M2 are engaged. It can rotate relative to R1. When the fourth member 40 is rotated relative to the fourth member support portion B in the first rotation direction R1, the second engaging portion M2 gets over at least one tooth 45a of the first engaging portion M1. After the second engaging portion M2 gets over at least one tooth 45a of the first engaging portion M1, the second engaging portion M2 will engage with the other teeth of the first engaging portion M1. .. Alternatively, by changing the shape of the first engaging portion M1 and / or the second engaging portion M2, the first engaging portion M1 and the second engaging portion M2 are engaged with each other. The 4 member 40 may not be able to rotate relative to the 4th member support portion B in both the first rotation direction R1 and the second rotation direction R2.
　図４に記載の例では、ロック機構Ｍは、第２係合部Ｍ２（より具体的には、第２係合部Ｍ２を有する係合部材１５）を、第１係合部Ｍ１に向けて付勢する付勢部材Ｍ３（例えば、ばね部材）を有する。このため、操作部材５０の押圧部５６が、第２係合部Ｍ２（より具体的には、第２係合部Ｍ２を有する係合部材１５）を押圧していない状態では、ロック機構Ｍは、自動的にロック状態（換言すれば、第１係合部Ｍ１と第２係合部Ｍ２とが係合した状態）となる。他方、図３に例示されるように、押圧部５６が、付勢部材Ｍ３の付勢力に抗して第２係合部Ｍ２を押圧すると、ロック機構Ｍの状態が、ロック状態からロック解除状態に切り替えられる。 In the example shown in FIG. 4, the lock mechanism M directs the second engaging portion M2 (more specifically, the engaging member 15 having the second engaging portion M2) toward the first engaging portion M1. It has an urging member M3 (for example, a spring member) to be urged. Therefore, in a state where the pressing portion 56 of the operating member 50 does not press the second engaging portion M2 (more specifically, the engaging member 15 having the second engaging portion M2), the lock mechanism M does not press. , Automatically locks (in other words, the first engaging portion M1 and the second engaging portion M2 are engaged). On the other hand, as illustrated in FIG. 3, when the pressing portion 56 presses the second engaging portion M2 against the urging force of the urging member M3, the state of the lock mechanism M changes from the locked state to the unlocked state. Can be switched to.
（第３部材３０、第４部材４０、および、操作部材５０の一例）
　図１乃至図４を参照して、第３部材３０、第４部材４０、および、操作部材５０の一例についてより詳細に説明する。 (Example of third member 30, fourth member 40, and operation member 50)
An example of the third member 30, the fourth member 40, and the operating member 50 will be described in more detail with reference to FIGS. 1 to 4.
　図３に記載の例では、第３部材３０は、ネジ棒３３を備える。なお、本明細書において、「ネジ棒」とは、内周面または外周面にネジ部が形成された棒状部分を備えた部材を意味する。換言すれば、ネジ棒は、外周面に雄ネジ部が形成された雄ネジ棒であってもよいし、内周面に雌ネジ部が形成された雌ネジ棒であってもよい。 In the example shown in FIG. 3, the third member 30 includes a screw rod 33. In addition, in this specification, a "screw rod" means a member provided with a rod-shaped portion having a threaded portion formed on an inner peripheral surface or an outer peripheral surface. In other words, the screw rod may be a male screw rod having a male screw portion formed on the outer peripheral surface or a female screw rod having a female screw portion formed on the inner peripheral surface.
　図３に記載の例では、第３部材３０は、第１部材１０に対する第３部材３０の相対回転を防止する回り止め部３１０を有する。回り止め部３１０が第１部材１０と接触することにより、第１部材１０に対する第３部材３０の相対回転が防止される。こうして、第４部材４０が第４部材支持部Ｂ（より具体的には、第１部材１０）に対して相対回転する際に、第３部材３０が第４部材支持部Ｂ（より具体的には、第１部材１０）に対して相対回転することが防止される。 In the example described in FIG. 3, the third member 30 has a detent portion 310 that prevents the third member 30 from rotating relative to the first member 10. When the detent portion 310 comes into contact with the first member 10, the relative rotation of the third member 30 with respect to the first member 10 is prevented. In this way, when the fourth member 40 rotates relative to the fourth member support portion B (more specifically, the first member 10), the third member 30 moves to the fourth member support portion B (more specifically). Is prevented from rotating relative to the first member 10).
　第４部材４０は、第３部材３０（より具体的には、ネジ棒３３）に螺合する第１ネジ部（４３ｆ）を備える。このため、第４部材４０が、第３部材３０に対して第１回転方向Ｒ１に相対回転すると、第３部材３０の押圧面３１ａは、第２部材２０の被押圧部２２に向かう方向（換言すれば、第１方向ＤＲ１）に移動する。また、第４部材４０が、第３部材３０に対して第２回転方向Ｒ２に相対回転すると、第３部材３０の押圧面３１ａは、第２部材２０の被押圧部２２から離れる方向（換言すれば、第２方向ＤＲ２）に移動する。なお、図３に記載の例では、第１ネジ部（４３ｆ）は、雌ネジ部である。代替的に、第１ネジ部は、雄ネジ部であってもよい。 The fourth member 40 includes a first screw portion (43f) that is screwed into the third member 30 (more specifically, the screw rod 33). Therefore, when the fourth member 40 rotates relative to the third member 30 in the first rotation direction R1, the pressing surface 31a of the third member 30 faces the pressed portion 22 of the second member 20 (in other words). Then, it moves to the first direction DR1). Further, when the fourth member 40 rotates relative to the third member 30 in the second rotation direction R2, the pressing surface 31a of the third member 30 moves away from the pressed portion 22 of the second member 20 (in other words, in other words). For example, it moves to the second direction DR2). In the example shown in FIG. 3, the first screw portion (43f) is a female screw portion. Alternatively, the first threaded portion may be a male threaded portion.
　第４部材４０は、操作部材５０に螺合する第２ネジ部（４３ｍ）を備える。このため、操作部材５０が、第４部材４０に対して第１回転方向Ｒ１に相対回転すると、操作部材５０は第４部材支持部Ｂから離れる方向（換言すれば、第２方向ＤＲ２）に移動する。また、操作部材５０が、第４部材４０に対して第２回転方向Ｒ２に相対回転すると、操作部材５０は第４部材支持部Ｂに近づく方向（換言すれば、第１方向ＤＲ１）に移動する。なお、図３に記載の例では、第２ネジ部（４３ｍ）は、雄ネジ部である。代替的に、第２ネジ部は、雌ネジ部であってもよい。なお、第４部材４０の第２ネジ部（４３ｍ）は、第４部材４０の第１ネジ部（４３ｆ）とは同方向のネジであることが好ましい。換言すれば、第４部材４０の第１ネジ部（４３ｆ）が左ネジである場合、第４部材４０の第２ネジ部（４３ｍ）は左ネジであることが好ましく、第４部材４０の第１ネジ部（４３ｆ）が右ネジである場合、第４部材４０の第２ネジ部（４３ｍ）は右ネジであることが好ましい。第４部材４０の第１ネジ部（４３ｆ）および第４部材４０の第２ネジ部（４３ｍ）が左ネジの場合、操作部材５０を第１回転方向Ｒ１に回転すると、第３部材３０が第１方向ＤＲ１に移動する。逆に、第４部材４０の第１ネジ部（４３ｆ）および第４部材４０の第２ネジ部（４３ｍ）が右ネジの場合、操作部材５０を第１回転方向Ｒ１に回転すると、第３部材３０が第２方向ＤＲ２に移動する。 The fourth member 40 includes a second screw portion (43 m) that is screwed into the operation member 50. Therefore, when the operating member 50 rotates relative to the fourth member 40 in the first rotation direction R1, the operating member 50 moves in a direction away from the fourth member support portion B (in other words, the second direction DR2). do. Further, when the operating member 50 rotates relative to the fourth member 40 in the second rotation direction R2, the operating member 50 moves in a direction approaching the fourth member support portion B (in other words, the first direction DR1). .. In the example shown in FIG. 3, the second screw portion (43 m) is a male screw portion. Alternatively, the second threaded portion may be a female threaded portion. The second screw portion (43 m) of the fourth member 40 is preferably a screw in the same direction as the first screw portion (43f) of the fourth member 40. In other words, when the first screw portion (43f) of the fourth member 40 is a left-hand thread, the second screw portion (43 m) of the fourth member 40 is preferably a left-hand thread, and the fourth member 40 is the first. When the 1-threaded portion (43f) is a right-handed screw, the second threaded portion (43m) of the 4th member 40 is preferably a right-handed screw. When the first screw portion (43f) of the fourth member 40 and the second screw portion (43m) of the fourth member 40 are left-handed threads, when the operation member 50 is rotated in the first rotation direction R1, the third member 30 becomes the first. Move to one-way DR1. On the contrary, when the first screw portion (43f) of the fourth member 40 and the second screw portion (43m) of the fourth member 40 are right-handed screws, when the operation member 50 is rotated in the first rotation direction R1, the third member 30 moves to the second direction DR2.
　なお、図３に記載の例では、操作部材５０が操作されるとき、操作部材５０のネジ部（５３ｆ）と第４部材４０の第２ネジ部（４３ｍ）との間の摩擦力は、第４部材４０の第１ネジ部（４３ｆ）と第３部材３０のネジ部（３３ｍ）との間の摩擦力よりも大きいが、代替的に、前者の摩擦力が後者の摩擦力より小さくても構わない。詳細は後述されるが、図３に記載の例では、操作部材５０が第１回転方向Ｒ１に操作されると、把持対象物Ｗが第１把持部１１および第２把持部２１によって把持されるまでは、（摩擦力がより小さい方の）、第４部材４０の第１ネジ部（４３ｆ）と第３部材３０のネジ部（３３ｍ）との間の相対移動により、ネジ棒３３が第１方向ＤＲ１に移動する。把持対象物Ｗが第１把持部１１および第２把持部２１によって把持された後、更に操作部材５０が第１回転方向Ｒ１に操作されると、（摩擦力がより大きい方の）、操作部材５０のネジ部（５３ｆ）と第４部材４０の第２ネジ部（４３ｍ）との間の相対移動により、操作部材５０が第２方向ＤＲ２に移動する。操作部材５０が第４部材４０の第２面４２に当接した後、更に操作部材５０が第１回転方向Ｒ１に操作されると、再び、ネジ棒３３が第１方向ＤＲ１に移動する。その結果、把持対象物Ｗが、操作部材５０が捻回される力に応じた押圧力によって、第２把持部２１と第１把持部１１とによって強力に把持される。 In the example shown in FIG. 3, when the operating member 50 is operated, the frictional force between the threaded portion (53f) of the operating member 50 and the second threaded portion (43m) of the fourth member 40 is the second. It is larger than the frictional force between the first screw portion (43f) of the 4 member 40 and the screw portion (33m) of the third member 30, but instead, even if the frictional force of the former is smaller than the frictional force of the latter. I do not care. Details will be described later, but in the example shown in FIG. 3, when the operating member 50 is operated in the first rotation direction R1, the gripping object W is gripped by the first grip portion 11 and the second grip portion 21. Until (the one with the smaller frictional force), the screw rod 33 becomes the first due to the relative movement between the first screw portion (43f) of the fourth member 40 and the screw portion (33 m) of the third member 30. Move in direction DR1. After the gripping object W is gripped by the first gripping portion 11 and the second gripping portion 21, when the operating member 50 is further operated in the first rotation direction R1 (the one having the larger frictional force), the operating member The operating member 50 moves in the second direction DR2 due to the relative movement between the threaded portion (53f) of the 50 and the second threaded portion (43m) of the fourth member 40. After the operating member 50 comes into contact with the second surface 42 of the fourth member 40, when the operating member 50 is further operated in the first rotation direction R1, the screw rod 33 moves to the first direction DR1 again. As a result, the gripping object W is strongly gripped by the second gripping portion 21 and the first gripping portion 11 by the pressing force corresponding to the twisting force of the operating member 50.
　図３に記載の例では、第４部材４０は、第４部材４０の中心軸まわりに第４部材支持部Ｂ（より具体的には、第１部材１０）に対して相対回転可能なように、第４部材支持部Ｂ（より具体的には、第１部材１０）に取り付けられている。また、第４部材４０は、第１方向ＤＲ１に平行な方向に第４部材支持部Ｂ（より具体的には、第１部材１０）に対して相対移動不能なように、第４部材支持部Ｂ（より具体的には、第１部材１０）に取り付けられている。 In the example shown in FIG. 3, the fourth member 40 is rotatable relative to the fourth member support portion B (more specifically, the first member 10) around the central axis of the fourth member 40. , Is attached to the fourth member support portion B (more specifically, the first member 10). Further, the fourth member 40 is a fourth member support portion so as to be immovable relative to the fourth member support portion B (more specifically, the first member 10) in a direction parallel to the first direction DR1. It is attached to B (more specifically, the first member 10).
　図２に記載の例では、第４部材４０は、上述の第１係合部Ｍ１を備える。図２に記載の例では、第１係合部Ｍ１は、環状に配置された複数の歯４５ａ（より具体的には、ラチェット歯）を含む。 In the example shown in FIG. 2, the fourth member 40 includes the above-mentioned first engaging portion M1. In the example shown in FIG. 2, the first engaging portion M1 includes a plurality of teeth 45a (more specifically, ratchet teeth) arranged in an annular shape.
　図３に記載の例では、第４部材４０は、第４部材４０に対する操作部材５０の上限位置を規定する第１面４１と、第４部材４０に対する操作部材５０の下限位置を規定する第２面４２とを備える。この場合、操作部材５０は、第１面４１によって規定される上限位置と第２面４２によって規定される下限位置との間の範囲内で、第４部材４０に対して上下動可能となる。なお、図３に記載の例では、操作部材５０から第４部材支持部Ｂに向かう方向が上方向とみなされる。 In the example shown in FIG. 3, the fourth member 40 has a first surface 41 that defines an upper limit position of the operation member 50 with respect to the fourth member 40, and a second surface 41 that defines a lower limit position of the operation member 50 with respect to the fourth member 40. A surface 42 is provided. In this case, the operating member 50 can move up and down with respect to the fourth member 40 within the range between the upper limit position defined by the first surface 41 and the lower limit position defined by the second surface 42. In the example shown in FIG. 3, the direction from the operating member 50 toward the fourth member support portion B is regarded as the upward direction.
　図３に記載の例では、第４部材４０は、第３部材３０の外側に配置される筒状の部材である。図３に記載の例では、第４部材４０は、両端が開放された筒状の部材であるが、第４部材４０は、一端が閉鎖された有底筒状の部材であってもよい。なお、第４部材４０の形状は筒状に限定されない。 In the example shown in FIG. 3, the fourth member 40 is a cylindrical member arranged outside the third member 30. In the example shown in FIG. 3, the fourth member 40 is a cylindrical member with both ends open, but the fourth member 40 may be a bottomed cylindrical member with one end closed. The shape of the fourth member 40 is not limited to a cylindrical shape.
　操作部材５０は、第４部材４０に螺合するネジ部（５３ｆ）を備える。図３に記載の例では、当該ネジ部（５３ｆ）は、雌ネジ部であるが、当該ネジ部（５３ｆ）は、雄ネジ部であってもよい。 The operation member 50 includes a screw portion (53f) screwed to the fourth member 40. In the example shown in FIG. 3, the threaded portion (53f) is a female threaded portion, but the threaded portion (53f) may be a male threaded portion.
　図３に記載の例では、操作部材５０は、上述の第１面４１に接触可能な第３面５４を備える。当該第３面５４が第１面４１に接触する位置が、操作部材５０の上限位置である。また、操作部材５０は、上述の第２面４２に接触可能な第４面５５を備える。当該第４面５５が第２面４２に接触する位置が、操作部材５０の下限位置である。 In the example shown in FIG. 3, the operating member 50 includes a third surface 54 that can come into contact with the first surface 41 described above. The position where the third surface 54 contacts the first surface 41 is the upper limit position of the operating member 50. Further, the operating member 50 includes a fourth surface 55 that can come into contact with the above-mentioned second surface 42. The position where the fourth surface 55 contacts the second surface 42 is the lower limit position of the operating member 50.
　図３に記載の例では、操作部材５０は、ロック機構Ｍの状態を、ロック状態からロック解除状態に切り替える押圧部５６を備える。図３に記載の例では、押圧部５６は、操作部材５０の第１方向ＤＲ１側の端部に設けられている。押圧部５６は、例えば、環状の突出部である。 In the example shown in FIG. 3, the operation member 50 includes a pressing portion 56 that switches the state of the lock mechanism M from the locked state to the unlocked state. In the example shown in FIG. 3, the pressing portion 56 is provided at the end portion of the operating member 50 on the DR1 side in the first direction. The pressing portion 56 is, for example, an annular protruding portion.
　図３に記載の例では、操作部材５０は、第４部材４０の外側に配置される筒状の部材である。図３に記載の例では、操作部材５０は、両端が開放された筒状の部材である。なお、操作部材５０の形状は筒状に限定されない。 In the example shown in FIG. 3, the operating member 50 is a cylindrical member arranged outside the fourth member 40. In the example shown in FIG. 3, the operating member 50 is a tubular member with both ends open. The shape of the operating member 50 is not limited to a cylindrical shape.
　図３に示されるように、操作部材５０が、第４部材４０に対する相対上限位置にあるときに、操作部材５０を第１回転方向Ｒ１に回転させることを想定する。この場合、操作部材５０を回転させる回転力が第４部材４０に伝達され、第４部材４０は操作部材５０とともに第１回転方向Ｒ１に回転する。また、第４部材４０が第１回転方向Ｒ１に回転すると、第３部材３０が第１方向ＤＲ１に移動する。よって、図３に記載の例では、操作部材５０を第１回転方向Ｒ１に回転させることにより、第３部材３０を第１方向ＤＲ１に移動させることができる。 As shown in FIG. 3, it is assumed that the operating member 50 is rotated in the first rotation direction R1 when the operating member 50 is in the relative upper limit position with respect to the fourth member 40. In this case, the rotational force that rotates the operating member 50 is transmitted to the fourth member 40, and the fourth member 40 rotates together with the operating member 50 in the first rotation direction R1. Further, when the fourth member 40 rotates in the first rotation direction R1, the third member 30 moves in the first direction DR1. Therefore, in the example shown in FIG. 3, the third member 30 can be moved to the first direction DR1 by rotating the operation member 50 in the first rotation direction R1.
　なお、操作部材５０を回転させる回転力の第４部材４０への伝達は、操作部材５０と第４部材４０との間の摩擦によって行われてもよいし、操作部材５０と第４部材４０との間の係合によって行われてもよい。図３に記載の例では、操作部材５０を回転させる回転力の第４部材４０への伝達は、操作部材５０の第３面５４と第４部材４０の第１面４１との間の摩擦によって行われる。 The rotational force that rotates the operating member 50 may be transmitted to the fourth member 40 by friction between the operating member 50 and the fourth member 40, or the operating member 50 and the fourth member 40. It may be done by engagement between. In the example shown in FIG. 3, the rotational force that rotates the operating member 50 is transmitted to the fourth member 40 by friction between the third surface 54 of the operating member 50 and the first surface 41 of the fourth member 40. Will be done.
　図４に示されるように、操作部材５０が、第４部材４０に対する相対上限位置と第４部材４０に対する相対下限位置との間の位置にあるときに、操作部材５０を第１回転方向Ｒ１に回転させることを想定する。この場合、操作部材５０は、第４部材４０に対して第１回転方向Ｒ１に相対回転する。操作部材５０が第４部材４０に対して第１回転方向Ｒ１に相対回転すると、操作部材５０は、第４部材４０に対して第２方向ＤＲ２に移動する。当該移動により、ロック機構Ｍの状態が、ロック解除状態（図３を参照。）からロック状態（図４を参照。）に切り替えられる。 As shown in FIG. 4, when the operating member 50 is in a position between the relative upper limit position with respect to the fourth member 40 and the relative lower limit position with respect to the fourth member 40, the operating member 50 is set to the first rotation direction R1. It is supposed to be rotated. In this case, the operating member 50 rotates relative to the fourth member 40 in the first rotation direction R1. When the operating member 50 rotates relative to the fourth member 40 in the first rotation direction R1, the operating member 50 moves in the second direction DR2 with respect to the fourth member 40. By this movement, the state of the lock mechanism M is switched from the unlocked state (see FIG. 3) to the locked state (see FIG. 4).
（把持機構Ｋ）
　図２に記載の例では、把持工具１Ａは、把持機構Ｋを備える。把持機構Ｋは、第１把持部１１を有する第１部材１０と、第２把持部２１を有する第２部材２０とを備える。図２に記載の例では、第２部材２０は、第１部材１０に対して揺動可能に連結されている。より具体的には、把持機構Ｋは、揺動軸ＡＸに沿って配置された第１軸部材６１を備え、第１部材１０と第２部材２０とが、当該第１軸部材６１を介して揺動可能に連結されている。 (Gripping mechanism K)
In the example shown in FIG. 2, the gripping tool 1A includes a gripping mechanism K. The grip mechanism K includes a first member 10 having a first grip portion 11 and a second member 20 having a second grip portion 21. In the example shown in FIG. 2, the second member 20 is swingably connected to the first member 10. More specifically, the gripping mechanism K includes a first shaft member 61 arranged along the swing shaft AX, and the first member 10 and the second member 20 are interposed via the first shaft member 61. It is connected so that it can swing.
　図２に記載の例では、第２部材２０の第２把持部２１は、可動把持部を構成する。より具体的には、可動把持部は、揺動軸ＡＸ（例えば、第１軸部材６１）まわりに揺動可能な把持部である。図２に記載の例では、第１部材１０の第１把持部１１は、固定把持部を構成する。より具体的には、固定把持部は、揺動軸ＡＸ（例えば、第１軸部材６１）まわりに揺動不能な把持部である。 In the example shown in FIG. 2, the second grip portion 21 of the second member 20 constitutes a movable grip portion. More specifically, the movable grip portion is a grip portion that can swing around the swing shaft AX (for example, the first shaft member 61). In the example shown in FIG. 2, the first grip portion 11 of the first member 10 constitutes a fixed grip portion. More specifically, the fixed grip portion is a grip portion that cannot swing around the swing shaft AX (for example, the first shaft member 61).

The spring member 62 uses the first member 10 and / or the second member 20 in a direction in which the distance between the first grip portion 11 of the first member 10 and the second grip portion 21 of the second member 20 increases. Encourage. In the example shown in FIG. 2, the spring member 62 is arranged between the first member 10 and the second member 20.
　図２に記載の例では、第２部材２０は、第３部材３０によって押圧される被押圧部２２を有する。第３部材３０の押圧面３１ａが被押圧部２２に向かう方向に移動することにより、第２部材２０が揺動軸ＡＸまわりを揺動して、第１把持部１１と第２把持部２１との間の間隔が縮小する。他方、第３部材３０の押圧面３１ａが被押圧部２２から離れる方向に移動することにより、ばね部材６２の付勢力によって第２部材２０が揺動軸ＡＸまわりを揺動して、第１把持部１１と第２把持部２１との間の間隔が拡大する。 In the example described in FIG. 2, the second member 20 has a pressed portion 22 pressed by the third member 30. As the pressing surface 31a of the third member 30 moves in the direction toward the pressed portion 22, the second member 20 swings around the swing axis AX, and the first grip portion 11 and the second grip portion 21 The spacing between them is reduced. On the other hand, as the pressing surface 31a of the third member 30 moves away from the pressed portion 22, the second member 20 swings around the swing shaft AX due to the urging force of the spring member 62, and the first grip is performed. The distance between the portion 11 and the second grip portion 21 is increased.
　図２に記載の例では、被押圧部２２は、第２部材２０の基端部に配置されている。被押圧部２２は、第２部材２０の他の部分と一体的に形成されてもよいし、第２部材２０の他の部分に取り付けられてもよい。図２に記載の例では、被押圧部２２は、球面２２ａを有する。この場合、被押圧部２２は、押圧面３１ａに対して円滑にスライド移動することができる。被押圧部２２が円滑にスライド移動することにより、第２部材２０が揺動軸ＡＸまわりを円滑に揺動する。 In the example shown in FIG. 2, the pressed portion 22 is arranged at the base end portion of the second member 20. The pressed portion 22 may be integrally formed with the other portion of the second member 20, or may be attached to the other portion of the second member 20. In the example shown in FIG. 2, the pressed portion 22 has a spherical surface 22a. In this case, the pressed portion 22 can smoothly slide and move with respect to the pressing surface 31a. As the pressed portion 22 slides smoothly, the second member 20 smoothly swings around the swing shaft AX.

In the example shown in FIG. 3, the second operation unit 65 is screwed to the shaft member 64.
　図３に記載の例では、ヘッド部Ｎ１が、ヘッド部支持部Ｎ２に対して、第２軸ＡＸ２（より具体的には、軸部材６４）まわりに回動されることにより、ヘッド部支持部Ｎ２に対するヘッド部Ｎ１の角度が調節される。 In the example shown in FIG. 3, the head portion N1 is rotated around the second axis AX2 (more specifically, the shaft member 64) with respect to the head portion support portion N2, whereby the head portion support portion is formed. The angle of the head portion N1 with respect to N2 is adjusted.

（第２の実施形態）
　図７乃至図９を参照して、第２の実施形態における把持工具１Ｂについて説明する。図７は、第２の実施形態における把持工具１Ｂを模式的に示す概略側面図である。図８および図９は、第２の実施形態における把持工具１Ｂの一部分の内部構造が断面図によって示され、把持工具１Ｂの他の部分が側面図によって示された図である。なお、図８は、把持工具１Ｂが把持対象物Ｗを把持する前の状態を示し、図９は、把持工具１Ｂが把持対象物Ｗを把持した後の状態を示す。 (Second embodiment)
The gripping tool 1B in the second embodiment will be described with reference to FIGS. 7 to 9. FIG. 7 is a schematic side view schematically showing the gripping tool 1B in the second embodiment. 8 and 9 are views in which the internal structure of a portion of the gripping tool 1B in the second embodiment is shown by cross-sectional view and the other portion of the gripping tool 1B is shown by a side view. Note that FIG. 8 shows a state before the gripping tool 1B grips the gripping object W, and FIG. 9 shows a state after the gripping tool 1B grips the gripping object W.
　第２の実施形態では、第１の実施形態と異なる点を中心に説明し、第１の実施形態において説明済みの事項についての繰り返しとなる説明は省略する。よって、第２の実施形態において明示的に説明されなかったとしても、第２の実施形態において、第１の実施形態で説明済みの事項を採用可能であることは言うまでもない。 In the second embodiment, the points different from those in the first embodiment will be mainly described, and the repetitive explanation of the matters explained in the first embodiment will be omitted. Therefore, it goes without saying that the matters explained in the first embodiment can be adopted in the second embodiment even if they are not explicitly explained in the second embodiment.
　第２の実施形態における第１部材１０は、第１の可動把持部を構成する第１把持部１１を有する点において、第１の実施形態における第１部材１０とは異なる。換言すれば、第２の実施形態において、第１把持部１１は、揺動軸ＡＸまわりに揺動しない固定把持部ではなく、揺動軸ＡＸまわりに揺動可能な可動把持部である。 The first member 10 in the second embodiment is different from the first member 10 in the first embodiment in that it has the first grip portion 11 constituting the first movable grip portion. In other words, in the second embodiment, the first grip portion 11 is not a fixed grip portion that does not swing around the swing shaft AX, but a movable grip portion that can swing around the swing shaft AX.
　第２の実施形態における把持工具１Ｂは、第１把持部１１を含む第１部材１０と、第２把持部２１を含む第２部材２０と、第１把持部１１と第２把持部２１との間の間隔が縮小するように第２部材２０に力を伝達可能な第３部材３０と、第１把持部１１と第２把持部２１との間の間隔が拡大することを防ぐロック状態と、第１把持部１１と第２把持部２１との間の間隔が拡大することを許容するロック解除状態とを切り替えるロック機構Ｍと、ロック機構Ｍの少なくとも一部を構成し、第３部材３０に螺合する第４部材４０と、第４部材４０に螺合する操作部材５０と、を備える。 The gripping tool 1B in the second embodiment includes a first member 10 including a first grip portion 11, a second member 20 including a second grip portion 21, and a first grip portion 11 and a second grip portion 21. A third member 30 capable of transmitting a force to the second member 20 so as to reduce the distance between them, and a locked state for preventing the distance between the first grip portion 11 and the second grip portion 21 from increasing. A lock mechanism M for switching between an unlocked state that allows an increase in the distance between the first grip portion 11 and the second grip portion 21, and at least a part of the lock mechanism M are formed in the third member 30. A fourth member 40 to be screwed and an operating member 50 to be screwed to the fourth member 40 are provided.
　よって、第２の実施形態における把持工具１Ｂは、第１の実施形態における把持工具１Ａと同様の効果を奏する。 Therefore, the gripping tool 1B in the second embodiment has the same effect as the gripping tool 1A in the first embodiment.
　図７に記載の例では、第２部材２０は、第１部材１０に対して揺動可能に連結されている。第１部材１０の第１把持部１１は、第１の可動把持部を構成する。より具体的には、第１把持部１１（より具体的には、第１把持部１１を備える第１部材１０）は、揺動軸ＡＸまわりを揺動可能である。第２部材２０の第２把持部２１は、第２の可動把持部を構成する。より具体的には、第２把持部２１（より具体的には、第２把持部２１を備える第２部材２０）は、揺動軸ＡＸまわりを揺動可能である。 In the example shown in FIG. 7, the second member 20 is swingably connected to the first member 10. The first grip portion 11 of the first member 10 constitutes a first movable grip portion. More specifically, the first grip portion 11 (more specifically, the first member 10 including the first grip portion 11) can swing around the swing shaft AX. The second grip portion 21 of the second member 20 constitutes a second movable grip portion. More specifically, the second grip portion 21 (more specifically, the second member 20 including the second grip portion 21) can swing around the swing shaft AX.
　図７に記載の例では、第３部材３０は、ネジ棒３３を含む。ネジ棒３３の雄ネジ部（３３ｍ）を構成する螺旋の方向は、例えば、図１に記載の例における雄ネジ部（３３ｍ）を構成する螺旋の方向とは、反対方向である。第３部材３０は、第２部材２０と接触する接触部３１を含む。図７に記載の例では、第２部材２０は、第２揺動軸ＡＸ３まわりを揺動可能なように、接触部３１に連結されている。 In the example shown in FIG. 7, the third member 30 includes a screw rod 33. The direction of the spiral constituting the male screw portion (33 m) of the screw rod 33 is, for example, the direction opposite to the direction of the spiral constituting the male screw portion (33 m) in the example shown in FIG. The third member 30 includes a contact portion 31 that comes into contact with the second member 20. In the example shown in FIG. 7, the second member 20 is connected to the contact portion 31 so as to be swingable around the second swing shaft AX3.
　図８に記載の例では、第４部材４０は、ネジ棒３３に螺合する第１ネジ部（４３ｆ）を備える。第４部材４０は、第４部材支持部Ｂに対して相対回転可能なように、第４部材支持部Ｂによって支持されている。 In the example shown in FIG. 8, the fourth member 40 includes a first screw portion (43f) screwed to the screw rod 33. The fourth member 40 is supported by the fourth member support portion B so as to be rotatable relative to the fourth member support portion B.
　図８に記載の例では、ロック機構Ｍは、第４部材４０に設けられた第１係合部Ｍ１と、第４部材支持部Ｂに設けられた第２係合部Ｍ２とを備える。 In the example shown in FIG. 8, the lock mechanism M includes a first engaging portion M1 provided on the fourth member 40 and a second engaging portion M2 provided on the fourth member support portion B.
　図８に記載の例において、操作部材５０が第４部材４０とともに、第３部材３０に対して第１回転方向Ｒ１に相対回転すると、第３部材３０は、第１方向ＤＲ１に移動する。その結果、第１部材１０の基端部と第２部材２０の基端部との間の間隔が縮小し、第１部材１０の第１把持部１１と第２部材２０の第２把持部２１との間の間隔が縮小する。こうして、把持対象物Ｗが、第１把持部１１と第２把持部２１とによって把持される。なお、図８に記載の例では、第１方向ＤＲ１は、下方向である。 In the example shown in FIG. 8, when the operating member 50 and the fourth member 40 rotate relative to the third member 30 in the first rotation direction R1, the third member 30 moves in the first direction DR1. As a result, the distance between the base end portion of the first member 10 and the base end portion of the second member 20 is reduced, and the first grip portion 11 of the first member 10 and the second grip portion 21 of the second member 20 are reduced. The interval between and is reduced. In this way, the gripping object W is gripped by the first gripping portion 11 and the second gripping portion 21. In the example shown in FIG. 8, the first direction DR1 is downward.
　図９に例示されるように、操作部材５０が、第４部材４０に対して第１回転方向Ｒ１に相対回転すると、操作部材５０に配置された押圧部５６が第２係合部Ｍ２から離間する。こうして、ロック機構Ｍの状態が、ロック解除状態（図８を参照。）からロック状態（図９を参照。）に変更される。 As illustrated in FIG. 9, when the operating member 50 rotates relative to the fourth member 40 in the first rotation direction R1, the pressing portion 56 arranged on the operating member 50 is separated from the second engaging portion M2. do. In this way, the state of the lock mechanism M is changed from the unlocked state (see FIG. 8) to the locked state (see FIG. 9).
　以上のとおり、図８および図９に記載の例では、操作部材５０を第１回転方向Ｒ１に回転させることにより、第１把持部１１と第２把持部２１との間の間隔の縮小、および、ロック解除状態からロック状態への切り替えの両方が実行される。 As described above, in the examples shown in FIGS. 8 and 9, by rotating the operating member 50 in the first rotation direction R1, the distance between the first grip portion 11 and the second grip portion 21 is reduced, and the distance between the first grip portion 11 and the second grip portion 21 is reduced. , Both switching from the unlocked state to the locked state are executed.
　図９に例示されるようにロック機構Ｍの状態がロック状態であるときに、操作部材５０を第２回転方向Ｒ２に回転させることを想定する。この場合、操作部材５０が第２回転方向Ｒ２に所定角度回転されるまではロック状態が維持され、操作部材５０が第２回転方向Ｒ２に所定角度以上回転すると、操作部材５０に配置された押圧部５６が第２係合部Ｍ２を押圧する。こうして、ロック状態（図９を参照。）からロック解除状態（図８を参照。）への切り替えが行われる。 As illustrated in FIG. 9, it is assumed that the operating member 50 is rotated in the second rotation direction R2 when the lock mechanism M is in the locked state. In this case, the locked state is maintained until the operating member 50 is rotated by a predetermined angle in the second rotation direction R2, and when the operating member 50 is rotated by a predetermined angle or more in the second rotation direction R2, the pressing arranged on the operating member 50 is performed. The portion 56 presses the second engaging portion M2. In this way, the lock state (see FIG. 9) is switched to the unlock state (see FIG. 8).
　ロック解除後に、操作部材５０が第４部材４０とともに、第３部材３０に対して第２回転方向Ｒ２に相対回転すると、第３部材３０は、第２方向ＤＲ２に移動する。その結果、第１部材１０の基端部と第２部材２０の基端部との間の間隔が拡大し、第１部材１０の第１把持部１１と第２部材２０の第２把持部２１との間の間隔が拡大する。こうして、把持対象物Ｗを、把持工具１Ｂから取り外すことができる。 After the lock is released, when the operating member 50 and the fourth member 40 rotate relative to the third member 30 in the second rotation direction R2, the third member 30 moves to the second direction DR2. As a result, the distance between the base end portion of the first member 10 and the base end portion of the second member 20 is widened, and the first grip portion 11 of the first member 10 and the second grip portion 21 of the second member 20 are widened. The distance between and is widened. In this way, the gripping object W can be removed from the gripping tool 1B.

　第３の実施形態では、第１の実施形態および第２の実施形態と異なる点を中心に説明し、第１の実施形態または第２の実施形態において説明済みの事項についての繰り返しとなる説明は省略する。よって、第３の実施形態において明示的に説明されなかったとしても、第３の実施形態において、第１の実施形態または第２の実施形態で説明済みの事項を採用可能であることは言うまでもない。 In the third embodiment, the differences from the first embodiment and the second embodiment will be mainly described, and the repetitive explanation of the matters explained in the first embodiment or the second embodiment will be described. Omit. Therefore, it is needless to say that the matters explained in the first embodiment or the second embodiment can be adopted in the third embodiment even if they are not explicitly explained in the third embodiment. ..
　第３の実施形態における第３部材３０は、ナット部３４を有する点において、第１の実施形態または第２の実施形態におけるネジ棒３３を有する第３部材とは異なる。 The third member 30 in the third embodiment is different from the third member having the screw rod 33 in the first embodiment or the second embodiment in that the nut portion 34 is provided.
　第３の実施形態における把持工具１Ｃは、第１把持部１１を含む第１部材１０と、第２把持部２１を含む第２部材２０と、第１把持部１１と第２把持部２１との間の間隔が縮小するように第２部材２０に力を伝達可能な第３部材３０と、第１把持部１１と第２把持部２１との間の間隔が拡大することを防ぐロック状態と、第１把持部１１と第２把持部２１との間の間隔が拡大することを許容するロック解除状態とを切り替えるロック機構Ｍと、ロック機構Ｍの少なくとも一部を構成し、第３部材３０に螺合する第４部材４０と、第４部材４０に螺合する操作部材５０と、を備える。 The gripping tool 1C in the third embodiment includes a first member 10 including a first grip portion 11, a second member 20 including a second grip portion 21, and a first grip portion 11 and a second grip portion 21. A third member 30 capable of transmitting a force to the second member 20 so as to reduce the distance between them, and a locked state for preventing the distance between the first grip portion 11 and the second grip portion 21 from increasing. A lock mechanism M for switching between an unlocked state that allows an increase in the distance between the first grip portion 11 and the second grip portion 21, and at least a part of the lock mechanism M are formed in the third member 30. A fourth member 40 to be screwed and an operating member 50 to be screwed to the fourth member 40 are provided.
　よって、第３の実施形態における把持工具１Ｃは、第１の実施形態における把持工具１Ａ、または、第２の実施形態における把持工具１Ｂと同様の効果を奏する。 Therefore, the gripping tool 1C in the third embodiment has the same effect as the gripping tool 1A in the first embodiment or the gripping tool 1B in the second embodiment.
　図１０に記載の例では、第２部材２０は、第１部材１０に対して揺動可能に連結されている。第１部材１０の第１把持部１１は、第１の可動把持部を構成する。より具体的には、第１把持部１１（より具体的には、第１把持部１１を備える第１部材１０）は、揺動軸ＡＸまわりを揺動可能である。第２部材２０の第２把持部２１は、第２の可動把持部を構成する。より具体的には、第２把持部２１（より具体的には、第２把持部２１を備える第２部材２０）は、揺動軸ＡＸまわりを揺動可能である。 In the example shown in FIG. 10, the second member 20 is swingably connected to the first member 10. The first grip portion 11 of the first member 10 constitutes a first movable grip portion. More specifically, the first grip portion 11 (more specifically, the first member 10 including the first grip portion 11) can swing around the swing shaft AX. The second grip portion 21 of the second member 20 constitutes a second movable grip portion. More specifically, the second grip portion 21 (more specifically, the second member 20 including the second grip portion 21) can swing around the swing shaft AX.
　図１０に記載の例では、第３部材３０は、第４部材４０に螺合するナット部３４を有する。ナット部３４の雌ネジ部３４ｆは、第４部材４０の一部を構成するネジ棒４４と螺合する。第３部材３０は、第２部材２０と接触する接触部３１を含む。図１０に記載の例では、第２部材２０は、第２揺動軸ＡＸ３まわりを揺動可能なように、接触部３１に連結されている。 In the example shown in FIG. 10, the third member 30 has a nut portion 34 screwed to the fourth member 40. The female screw portion 34f of the nut portion 34 is screwed with the screw rod 44 which constitutes a part of the fourth member 40. The third member 30 includes a contact portion 31 that comes into contact with the second member 20. In the example shown in FIG. 10, the second member 20 is connected to the contact portion 31 so as to be swingable around the second swing shaft AX3.
　図１０に記載の例では、第４部材４０は、ナット部３４に螺合する雄ネジ部４４ｍを備える。第４部材４０は、第４部材支持部Ｂに対して相対回転可能なように、第４部材支持部Ｂによって支持されている。 In the example shown in FIG. 10, the fourth member 40 includes a male screw portion 44 m screwed to the nut portion 34. The fourth member 40 is supported by the fourth member support portion B so as to be rotatable relative to the fourth member support portion B.
　図１１に記載の例では、ロック機構Ｍは、第４部材４０に設けられた第１係合部Ｍ１と、第４部材支持部Ｂに設けられた第２係合部Ｍ２とを備える。 In the example shown in FIG. 11, the lock mechanism M includes a first engaging portion M1 provided on the fourth member 40 and a second engaging portion M2 provided on the fourth member support portion B.
　図１１に記載の例において、操作部材５０が第４部材４０とともに、第３部材３０に対して第１回転方向Ｒ１に相対回転すると、第３部材３０（より具体的には、ナット部３４）は、第１方向ＤＲ１に移動する。その結果、第１部材１０の基端部と第２部材２０の基端部との間の間隔が縮小し、第１部材１０の第１把持部１１と第２部材２０の第２把持部２１との間の間隔が縮小する。こうして、把持対象物Ｗが、第１把持部１１と第２把持部２１とによって把持される。なお、図１１に記載の例では、第１方向ＤＲ１は、下方向である。 In the example shown in FIG. 11, when the operating member 50 and the fourth member 40 rotate relative to the third member 30 in the first rotation direction R1, the third member 30 (more specifically, the nut portion 34). Moves to the first direction DR1. As a result, the distance between the base end portion of the first member 10 and the base end portion of the second member 20 is reduced, and the first grip portion 11 of the first member 10 and the second grip portion 21 of the second member 20 are reduced. The interval between and is reduced. In this way, the gripping object W is gripped by the first gripping portion 11 and the second gripping portion 21. In the example shown in FIG. 11, the first direction DR1 is downward.
　図１２に例示されるように、操作部材５０が、第４部材４０に対して第１回転方向Ｒ１に相対回転すると、操作部材５０に配置された押圧部５６が第２係合部Ｍ２から離間する。こうして、ロック機構Ｍの状態が、ロック解除状態（図１１を参照。）からロック状態（図１２を参照。）に変更される。 As illustrated in FIG. 12, when the operating member 50 rotates relative to the fourth member 40 in the first rotation direction R1, the pressing portion 56 arranged on the operating member 50 is separated from the second engaging portion M2. do. In this way, the state of the lock mechanism M is changed from the unlocked state (see FIG. 11) to the locked state (see FIG. 12).
　以上のとおり、図１１および図１２に記載の例では、操作部材５０を第１回転方向Ｒ１に回転させることにより、第１把持部１１と第２把持部２１との間の間隔の縮小、および、ロック解除状態からロック状態への切り替えの両方が実行される。 As described above, in the examples shown in FIGS. 11 and 12, by rotating the operating member 50 in the first rotation direction R1, the distance between the first grip portion 11 and the second grip portion 21 is reduced, and the distance between the first grip portion 11 and the second grip portion 21 is reduced. , Both switching from the unlocked state to the locked state are executed.
　図１２に例示されるようにロック機構Ｍの状態がロック状態であるときに、操作部材５０を第２回転方向Ｒ２に回転させることを想定する。この場合、操作部材５０が第２回転方向Ｒ２に所定角度回転されるまではロック状態が維持され、操作部材５０が第２回転方向Ｒ２に所定角度以上回転すると、操作部材５０に配置された押圧部５６が第２係合部Ｍ２を押圧する。こうして、ロック状態（図１２を参照。）からロック解除状態（図１１を参照。）への切り替えが行われる。 As illustrated in FIG. 12, it is assumed that the operating member 50 is rotated in the second rotation direction R2 when the lock mechanism M is in the locked state. In this case, the locked state is maintained until the operating member 50 is rotated by a predetermined angle in the second rotation direction R2, and when the operating member 50 is rotated by a predetermined angle or more in the second rotation direction R2, the pressing arranged on the operating member 50 is performed. The portion 56 presses the second engaging portion M2. In this way, the lock state (see FIG. 12) is switched to the unlock state (see FIG. 11).
　ロック解除後に、操作部材５０が第４部材４０とともに、第３部材３０に対して第２回転方向Ｒ２に相対回転すると、第３部材３０（より具体的には、ナット部３４）は、第２方向ＤＲ２に移動する。その結果、第１部材１０の基端部と第２部材２０の基端部との間の間隔が拡大し、第１部材１０の第１把持部１１と第２部材２０の第２把持部２１との間の間隔が拡大する。こうして、把持対象物Ｗを、把持工具１Ｃから取り外すことができる。 After the lock is released, when the operating member 50 and the fourth member 40 rotate relative to the third member 30 in the second rotation direction R2, the third member 30 (more specifically, the nut portion 34) becomes the second member. Move in direction DR2. As a result, the distance between the base end portion of the first member 10 and the base end portion of the second member 20 is widened, and the first grip portion 11 of the first member 10 and the second grip portion 21 of the second member 20 are widened. The distance between and is widened. In this way, the gripping object W can be removed from the gripping tool 1C.
（把持工具の使用方法）
　図１乃至図１３を参照して、実施形態における把持工具１の使用方法の一例について説明する。図１３は、実施形態における把持工具１の使用方法の一例を示すフローチャートである。 (How to use the grip tool)
An example of how to use the gripping tool 1 in the embodiment will be described with reference to FIGS. 1 to 13. FIG. 13 is a flowchart showing an example of how to use the gripping tool 1 in the embodiment.
　実施形態における把持工具１の使用方法で用いられる把持工具は、第１の実施形態における把持工具１Ａであってもよいし、第２の実施形態における把持工具１Ｂであってもよいし、第３の実施形態における把持工具１Ｃであってもよいし、その他の把持工具であってもよい。 The gripping tool used in the method of using the gripping tool 1 in the embodiment may be the gripping tool 1A in the first embodiment, the gripping tool 1B in the second embodiment, or the third. It may be the gripping tool 1C in the embodiment, or it may be another gripping tool.
　把持工具１は、第１把持部１１を含む第１部材１０と、第２把持部２１を含む第２部材２０と、第１把持部１１と第２把持部２１との間の間隔が縮小するように第２部材２０に力を伝達可能な第３部材３０と、第１把持部１１と第２把持部２１との間の間隔が拡大することを防ぐロック状態と、第１把持部１１と第２把持部２１との間の間隔が拡大することを許容するロック解除状態とを切り替えるロック機構Ｍと、ロック機構Ｍの少なくとも一部を構成し、第３部材３０に螺合する第４部材４０と、第４部材４０に螺合する操作部材５０と、を備える。 In the grip tool 1, the distance between the first member 10 including the first grip portion 11, the second member 20 including the second grip portion 21, and the first grip portion 11 and the second grip portion 21 is reduced. As described above, the third member 30 capable of transmitting a force to the second member 20, the locked state for preventing the distance between the first grip portion 11 and the second grip portion 21 from increasing, and the first grip portion 11 A fourth member that constitutes at least a part of the lock mechanism M and the lock mechanism M that switches between an unlocked state that allows an increase in the distance between the second grip portion 21 and the third member 30 and is screwed into the third member 30. A 40 and an operating member 50 screwed to the fourth member 40 are provided.
　図１、図８、あるいは、図１１に示されるように、第１ステップＳＴ１において、第１把持部１１と第２把持部２１との間に、把持対象物Ｗが配置される。第１ステップＳＴ１は、配置工程である。第１ステップＳＴ１（配置工程）は、例えば、把持対象物Ｗを、把持工具１の開口ＯＰを介して、第１把持部１１と第２把持部２１との間の空間に移動させることにより実行される。把持対象物Ｗは、例えば、電線等の線材、または、掴線器等の工具である。なお、把持対象物Ｗは、線材、工具に限定されない。 As shown in FIGS. 1, 8 or 11, in the first step ST1, the gripping object W is arranged between the first gripping portion 11 and the second gripping portion 21. The first step ST1 is an arrangement step. The first step ST1 (arrangement step) is executed, for example, by moving the gripping object W to the space between the first gripping portion 11 and the second gripping portion 21 through the opening OP of the gripping tool 1. Will be done. The gripping object W is, for example, a wire rod such as an electric wire or a tool such as a wire gripper. The gripping object W is not limited to the wire rod and the tool.
　第２ステップＳＴ２において、第１把持部１１と第２把持部２１とによって把持対象物Ｗが把持される。第２ステップＳＴ２は、把持対象物Ｗを把持する把持工程である。第２ステップＳＴ２（把持工程）は、操作部材５０を第１回転方向Ｒ１に回転させることにより実行される。 In the second step ST2, the gripping object W is gripped by the first gripping portion 11 and the second gripping portion 21. The second step ST2 is a gripping step of gripping the gripping object W. The second step ST2 (grasping step) is executed by rotating the operating member 50 in the first rotation direction R1.
　第２ステップＳＴ２（把持工程）は、第４部材４０と第３部材３０との間の相対回転により、第１把持部１１と第２把持部２１との間の間隔を縮小する間隔縮小工程と、第４部材４０と操作部材５０との間の相対回転により、ロック機構Ｍをロック解除状態からロック状態に切り替える第１切替工程と、を含む。 The second step ST2 (grip step) is a gap reducing step of reducing the gap between the first grip portion 11 and the second grip portion 21 by the relative rotation between the fourth member 40 and the third member 30. The first switching step of switching the lock mechanism M from the unlocked state to the locked state by the relative rotation between the fourth member 40 and the operating member 50 is included.
　間隔縮小工程では、第４部材４０と第３部材３０との間の相対回転により、第４部材４０に螺合する第３部材３０が、第１方向ＤＲ１に移動する。こうして、第３部材３０が第２部材２０に力を伝達し、第２部材２０に設けられた第２把持部２１と第１部材１０に設けられた第１把持部１１との間の間隔が縮小する。なお、間隔縮小工程では、操作部材５０を回転させる回転力が第４部材４０に伝達され、第４部材４０が操作部材５０とともに第１回転方向Ｒ１に回転する。当該回転力の伝達は、例えば、操作部材５０の位置が、第４部材４０に対する相対上限位置にある状態で実行される（図３、図８、または、図１１を参照。）。より具体的には、第４部材４０の第１面４１と操作部材５０の第３面５４との間の接触によって、上述の回転力が操作部材５０から第４部材４０に伝達される。 In the interval reducing step, the third member 30 screwed to the fourth member 40 moves to the first direction DR1 due to the relative rotation between the fourth member 40 and the third member 30. In this way, the third member 30 transmits the force to the second member 20, and the distance between the second grip portion 21 provided on the second member 20 and the first grip portion 11 provided on the first member 10 is increased. to shrink. In the interval reducing step, the rotational force for rotating the operation member 50 is transmitted to the fourth member 40, and the fourth member 40 rotates together with the operation member 50 in the first rotation direction R1. The transmission of the rotational force is performed, for example, in a state where the position of the operating member 50 is at the relative upper limit position with respect to the fourth member 40 (see FIG. 3, FIG. 8 or FIG. 11). More specifically, the above-mentioned rotational force is transmitted from the operating member 50 to the fourth member 40 by the contact between the first surface 41 of the fourth member 40 and the third surface 54 of the operating member 50.
　間隔縮小工程の実行により、第１把持部１１と第２把持部２１とによって把持対象物Ｗが把持される（例えば、図２、図９、または、図１２を参照。）。第１把持部１１と第２把持部２１とによって把持対象物Ｗが把持されると、第２把持部２１を含む第２部材２０は、第１把持部１１に対して、実質的に相対移動することができなくなる。その結果、第１回転方向Ｒ１に第４部材４０が回転することができなくなる。第４部材４０が回転できなくなると、操作部材５０を回転させる回転力は第４部材４０に伝達されず、操作部材５０は第４部材４０に対して相対回転する。 By executing the interval reducing step, the gripping object W is gripped by the first gripping portion 11 and the second gripping portion 21 (see, for example, FIG. 2, FIG. 9, or FIG. 12). When the gripping object W is gripped by the first grip portion 11 and the second grip portion 21, the second member 20 including the second grip portion 21 moves substantially relative to the first grip portion 11. You will not be able to. As a result, the fourth member 40 cannot rotate in the first rotation direction R1. When the fourth member 40 cannot rotate, the rotational force for rotating the operating member 50 is not transmitted to the fourth member 40, and the operating member 50 rotates relative to the fourth member 40.
　間隔縮小工程の実行後、操作部材５０を更に第１回転方向Ｒ１に回転させることにより、第１切替工程が実行される。第１切替工程では、第４部材４０と操作部材５０との間の相対回転により、操作部材５０が進出位置（図３、図８、または、図１１を参照。）から退避位置（図４、図９、または、図１２を参照。）に移動する。操作部材５０が退避位置に移動することにより、操作部材５０の押圧部５６が、第２係合部Ｍ２から離間する。押圧部５６が第２係合部Ｍ２から離間すると、付勢部材Ｍ３によって第１係合部Ｍ１に向かう方向に付勢された第２係合部Ｍ２が、第１係合部Ｍ１と係合する（図４、図９、または、図１２を参照。）。こうして、ロック機構Ｍが、ロック解除状態からロック状態に切り替えられる。 After executing the interval reducing step, the first switching step is executed by further rotating the operating member 50 in the first rotation direction R1. In the first switching step, the operating member 50 moves from the advanced position (see FIG. 3, FIG. 8 or FIG. 11) to the retracted position (FIG. 4, FIG. 11) due to the relative rotation between the fourth member 40 and the operating member 50. See FIG. 9 or FIG. 12). When the operating member 50 moves to the retracted position, the pressing portion 56 of the operating member 50 is separated from the second engaging portion M2. When the pressing portion 56 is separated from the second engaging portion M2, the second engaging portion M2 urged by the urging member M3 in the direction toward the first engaging portion M1 engages with the first engaging portion M1. (See FIG. 4, FIG. 9, or FIG. 12). In this way, the lock mechanism M is switched from the unlocked state to the locked state.
　なお、第１切替工程では、第４部材４０に対する操作部材５０の相対位置が、相対上限位置から相対下限位置に移動することが好ましい。操作部材５０の位置が、相対上限位置から相対下限位置に移動することにより、ロック機構Ｍが、ロック解除状態からロック状態に確実に切り替えられる。 In the first switching step, it is preferable that the relative position of the operating member 50 with respect to the fourth member 40 moves from the relative upper limit position to the relative lower limit position. By moving the position of the operating member 50 from the relative upper limit position to the relative lower limit position, the lock mechanism M is reliably switched from the unlocked state to the locked state.
　実施形態における把持工具１の使用方法では、操作部材５０を第１回転方向Ｒ１に回転させるだけで、第１把持部１１と第２把持部２１との間の間隔を縮小する間隔縮小工程と、ロック機構Ｍをロック解除状態からロック状態に切り替える第１切替工程とが、連続的に実行される。よって、実施形態では、簡易な操作で、ロック状態とロック解除状態とを切り替え可能な把持工具１の使用方法が提供される。 In the method of using the gripping tool 1 in the embodiment, a spacing reducing step of reducing the spacing between the first gripping portion 11 and the second gripping portion 21 by simply rotating the operating member 50 in the first rotation direction R1 is provided. The first switching step of switching the lock mechanism M from the unlocked state to the locked state is continuously executed. Therefore, in the embodiment, there is provided a method of using the gripping tool 1 that can switch between the locked state and the unlocked state by a simple operation.
　なお、把持工程（第２ステップＳＴ２）は、上述の間隔縮小工程、および、上述の第１切替工程に加えて、第２の間隔縮小工程を含んでいてもよい。第２の間隔縮小工程は、第１把持部１１と第２把持部２１との間の間隔を更に小さくする工程である。第２の間隔縮小工程は、増し締め工程であるということもできる。第２の間隔縮小工程は、第１切替工程の実行後、換言すれば、第４部材４０に対する操作部材５０の相対位置が相対下限位置に移動した後、操作部材５０を更に第１回転方向Ｒ１に回転させることにより実行される。 The gripping step (second step ST2) may include a second interval reducing step in addition to the above-mentioned interval reducing step and the above-mentioned first switching step. The second gap reducing step is a step of further reducing the gap between the first grip portion 11 and the second grip portion 21. It can also be said that the second interval reducing step is a retightening step. In the second interval reducing step, after the execution of the first switching step, in other words, after the relative position of the operating member 50 with respect to the fourth member 40 moves to the relative lower limit position, the operating member 50 is further moved to the first rotation direction R1. It is executed by rotating to.
　第２の間隔縮小工程の実行中、操作部材５０は相対下限位置にある。より具体的には、操作部材５０の第４面５５（図４、図９、または、図１２を参照。）が第４部材４０の第２面４２と接触している。このため、操作部材５０は、第４部材４０に対して、第１回転方向Ｒ１に相対回転することができない。この場合、操作部材５０を第１回転方向Ｒ１に回転させると、上述の間隔縮小工程と同様に、操作部材５０および第４部材４０は、第３部材３０に対して、第１回転方向Ｒ１に相対回転することとなる。 During the execution of the second interval reduction step, the operating member 50 is in the relative lower limit position. More specifically, the fourth surface 55 of the operating member 50 (see FIGS. 4, 9, or 12) is in contact with the second surface 42 of the fourth member 40. Therefore, the operating member 50 cannot rotate relative to the fourth member 40 in the first rotation direction R1. In this case, when the operation member 50 is rotated in the first rotation direction R1, the operation member 50 and the fourth member 40 are in the first rotation direction R1 with respect to the third member 30 as in the above-mentioned interval reducing step. It will rotate relative to each other.
　第４部材４０が、第３部材３０に対して、第１回転方向Ｒ１に相対回転すると、第４部材４０の第１係合部Ｍ１は、第２係合部Ｍ２を乗り越えて移動する。その結果、第３部材３０は、第４部材４０の長手軸方向に沿って、第１方向ＤＲ１に移動する。こうして、第１把持部１１と第２部材２０に設けられた第２把持部２１との間の間隔が更に小さくなる。 When the fourth member 40 rotates relative to the third member 30 in the first rotation direction R1, the first engaging portion M1 of the fourth member 40 moves over the second engaging portion M2. As a result, the third member 30 moves in the first direction DR1 along the longitudinal axis direction of the fourth member 40. In this way, the distance between the first grip portion 11 and the second grip portion 21 provided on the second member 20 is further reduced.
　なお、第２の間隔縮小工程では、操作部材５０を回転させる回転力が第４部材４０に伝達され、第４部材４０が操作部材５０とともに第１回転方向Ｒ１に回転する。当該回転力の伝達は、操作部材５０の位置が、第４部材４０に対する相対下限位置にある状態で実行されることが好ましい。より具体的には、操作部材５０の第４面５５（図４、図９、または、図１２を参照。）と第４部材４０の第２面４２との間の接触によって、上述の回転力が操作部材５０から第４部材４０に伝達される。 In the second interval reduction step, the rotational force for rotating the operating member 50 is transmitted to the fourth member 40, and the fourth member 40 rotates together with the operating member 50 in the first rotation direction R1. It is preferable that the transmission of the rotational force is executed in a state where the position of the operating member 50 is at the lower limit position relative to the fourth member 40. More specifically, the above-mentioned rotational force due to contact between the fourth surface 55 of the operating member 50 (see FIGS. 4, 9, or 12) and the second surface 42 of the fourth member 40. Is transmitted from the operating member 50 to the fourth member 40.
（把持解除工程）
　続いて、第１把持部１１および第２把持部２１による把持対象物Ｗの把持を解除する把持解除工程（換言すれば、第３ステップＳＴ３）について説明する。 (Gripping release process)
Subsequently, a grip release step (in other words, a third step ST3) for releasing the grip of the gripping object W by the first grip portion 11 and the second grip portion 21 will be described.
　第３ステップＳＴ３（把持解除工程）では、操作部材５０を第２回転方向Ｒ２に回転させることにより、第１把持部１１および第２把持部２１による把持対象物Ｗの把持が解除される。 In the third step ST3 (grip release step), the operation member 50 is rotated in the second rotation direction R2 to release the grip of the gripping object W by the first grip portion 11 and the second grip portion 21.
　第３ステップＳＴ３（把持解除工程）は、第４部材４０と操作部材５０との間の相対回転により、ロック機構Ｍをロック状態からロック解除状態に切り替える第２切替工程と、第４部材４０と第３部材３０との間の相対回転により、第１把持部１１と第２把持部２１との間の間隔を拡大する間隔拡大工程と、を含む。 The third step ST3 (grasping release step) includes a second switching step of switching the lock mechanism M from the locked state to the unlocked state by relative rotation between the fourth member 40 and the operating member 50, and the fourth member 40. A step of increasing the distance between the first grip portion 11 and the second grip portion 21 by relative rotation between the third member 30 and the second grip portion 21 is included.
　第２切替工程では、第４部材４０と操作部材５０との間の相対回転により、操作部材５０が、退避位置（図４、図９、または、図１２を参照。）から進出位置（図３、図８、または、図１１を参照。）に移動する。操作部材５０が進出位置に移動することにより、操作部材５０の押圧部５６が、第２係合部Ｍ２を押圧する。押圧部５６が第２係合部Ｍ２を押圧すると、第１係合部Ｍ１と第２係合部Ｍ２との間の係合が解除される。こうして、ロック機構Ｍが、ロック状態からロック解除状態に切り替えられる。 In the second switching step, due to the relative rotation between the fourth member 40 and the operating member 50, the operating member 50 moves from the retracted position (see FIG. 4, FIG. 9, or FIG. 12) to the advanced position (FIG. 3). , FIG. 8 or FIG. 11). As the operating member 50 moves to the advanced position, the pressing portion 56 of the operating member 50 presses the second engaging portion M2. When the pressing portion 56 presses the second engaging portion M2, the engagement between the first engaging portion M1 and the second engaging portion M2 is released. In this way, the lock mechanism M is switched from the locked state to the unlocked state.
　なお、第２切替工程では、第４部材４０に対する操作部材５０の相対位置が、相対下限位置から相対上限位置に移動することが好ましい。操作部材５０の位置が、相対下限位置から相対上限位置に移動することにより、ロック機構Ｍが、ロック状態からロック解除状態に確実に切り替えられる。 In the second switching step, it is preferable that the relative position of the operating member 50 with respect to the fourth member 40 moves from the relative lower limit position to the relative upper limit position. By moving the position of the operating member 50 from the relative lower limit position to the relative upper limit position, the lock mechanism M is reliably switched from the locked state to the unlocked state.
　第２切替工程の実行後、操作部材５０を更に第２回転方向Ｒ２に回転させることにより、間隔拡大工程が実行される。間隔拡大工程では、第４部材４０と第３部材３０との間の相対回転により、第４部材４０に螺合する第３部材３０が、第２方向ＤＲ２に移動する。こうして、第２把持部２１と第１把持部１１との間の間隔が拡大する。なお、間隔拡大工程では、操作部材５０を回転させる回転力が第４部材４０に伝達され、第４部材４０が操作部材５０とともに第２回転方向Ｒ２に回転する。当該回転力の伝達は、操作部材５０の位置が、第４部材４０に対する相対上限位置にある状態で実行される（図３、図８、または、図１１を参照。）。より具体的には、第４部材４０の第１面４１と操作部材５０の第３面５４との間の接触によって、上述の回転力が操作部材５０から第４部材４０に伝達される。 After executing the second switching step, the interval expanding step is executed by further rotating the operating member 50 in the second rotation direction R2. In the interval expanding step, the third member 30 screwed to the fourth member 40 moves in the second direction DR2 due to the relative rotation between the fourth member 40 and the third member 30. In this way, the distance between the second grip portion 21 and the first grip portion 11 is increased. In the interval expanding step, the rotational force for rotating the operating member 50 is transmitted to the fourth member 40, and the fourth member 40 rotates together with the operating member 50 in the second rotation direction R2. The transmission of the rotational force is performed with the position of the operating member 50 at the upper limit position relative to the fourth member 40 (see FIG. 3, FIG. 8 or FIG. 11). More specifically, the above-mentioned rotational force is transmitted from the operating member 50 to the fourth member 40 by the contact between the first surface 41 of the fourth member 40 and the third surface 54 of the operating member 50.
　間隔拡大工程の実行により、第１把持部１１および第２把持部２１による把持対象物Ｗの把持が解除される。 By executing the interval expanding step, the gripping object W is released from being gripped by the first gripping portion 11 and the second gripping portion 21.
　実施形態における把持工具１の使用方法では、操作部材５０を第２回転方向Ｒ２に回転させるだけで、ロック機構Ｍの状態をロック状態からロック解除状態に切り替える第２切替工程と、第１把持部１１と第２把持部２１との間の間隔を拡大する間隔拡大工程とが、連続的に実行される。よって、実施形態では、簡易な操作で、ロック状態とロック解除状態とを切り替え可能な把持工具１の使用方法が提供される。 In the method of using the gripping tool 1 in the embodiment, a second switching step of switching the state of the lock mechanism M from the locked state to the unlocked state by simply rotating the operating member 50 in the second rotation direction R2, and the first gripping portion. The interval expanding step of increasing the interval between the 11 and the second grip portion 21 is continuously executed. Therefore, in the embodiment, there is provided a method of using the gripping tool 1 that can switch between the locked state and the unlocked state by a simple operation.

In the example shown in FIG. 6, the surface of the pressed portion 22 of the second member 20 includes a spherical surface 22a. Therefore, when the head portion N1 rotates with respect to the head portion support portion N2, the sliding between the pressed portion 22 of the second member 20 and the contact portion 31 of the third member 30 is smoothly performed. .. The center of the spherical surface 22a is preferably arranged in the vicinity of the extension line of the second axis AX2.
