The protrusion 4A of the movement for preventing clamp body 21 also can be set in clamp body incorporating section 4.For example, making Protrusion 4A is abutted with the reinforcement part 27 of clamp body 21, and thus clamp body 21 is difficult to mobile to far side.The shape of protrusion 4A Such as it can be the polygons such as circle, ellipse, rectangle, triangle or these combination.In FIG. 1 to FIG. 3, protrusion The far side of 4A is formed as round, and proximal side is formed as from the round center elongated rectangle that proximally side extends, but protrusion Shape be not particularly limited.

Insertion access 3 is the access being inserted into for thread 30, is formed as connecting insert port 2 and clamp body incorporating section 4.It is logical In normal situation, insertion access 3 is formed as extending to clamp body incorporating section 4 as the crow flies from insert port 2, is inserted into the extension of access 3 Direction is equivalent to the direction from insert port 2 to the entrance of clamp body incorporating section 4, is inserted into the proximal side of the extending direction of access 3 It is 2 side of insert port for being inserted into access 3, far side is 4 side of clamp body incorporating section.Insert port 2 is equivalent to entering for insertion access 3 Mouthful, it is formed in the lateral surface of clamp box 1.

Ring incorporating section 5 is the space of the dead ring 29 of storage fastening clamp body 21, is set to the midway of insertion access 3. Fig. 8~Figure 11 is indicated inside clamp box, and indicates to expand the top view of the part VIII shown in Fig. 3.In Fig. 8~Figure 11, Dead ring 29 is accommodated in ring incorporating section 5 in the state of extending direction of the radial central axis along insertion access 3.In the present invention Clamp box 1 in also include to be accommodated with the mode of dead ring 29 in ring incorporating section 5 and be not accommodated with tightly in ring incorporating section 5 Gu the arbitrary mode in the mode of ring 29.

Ring incorporating section 5 has the abutting part 6 for preventing the movement of dead ring 29 to the extending direction for being inserted into access 3.It supports Socket part 6 is contacted with dead ring 29, so as to prevent the movement of dead ring 29, therefore is able to suppress dead ring 29 to than clamp master The peri position end of body 21 is mobile by the position of far side and makes the base end part 23 of clamp body 21 into the feelings of the inside of dead ring 29 Condition, the base end part 23 of clamp body 21 is not by the internal diameter restrictions of dead ring 29, to be easily opened.Therefore, it is easy thread 30 linking part 32 is linked to the base end part 23 of clamp body 21.In addition, can also prevent dead ring 29 to the close of insertion access 3 Position side or far side are mobile, and the case where fall off from ring incorporating section 5, clamp box 1.In the present invention, clamp body incorporating section 4 is matched It is placed in the position that far side is leaned on than ring incorporating section 5, the amphi position end of dead ring 29 is configured at more close than the peri position end of clamp body 21 The position of position side.

Using Fig. 8~Figure 11, to being described in detail for the movement of clamp box 1 of the invention.Firstly, as shown in figure 8, quasi- It is standby to be configured with clamp body 21 in clamp body incorporating section 4, and the clamp box 1 of dead ring 29 is configured in ring incorporating section 5.It connects down Come, is inserted in the thread 30 that far side has linking part 32 to insertion access 3 from the insert port 2 of clamp box 1.In fig. 8, with Mode shown in Fig. 7 is identical, linking part 32 is provided with openings 33A and positioned at the convex for leaning on far side than openings 33A Portion 33B and as engaging receiving portion 33, but engage receiving portion 33 shape be not particularly limited.Convex shaped part 33B is formed as court It is prominent to far side, and become the tapered shape in front end towards far side.Engaging receiving portion 33 is also possible to be not provided with penetrating through Mouth 33A, and the shape being only made of convex shaped part 33B.In this case, holding section 25 and the convex shaped part of clamp body 21 can be made 33B engaging.

As shown in figure 9, keeping thread 30 mobile to far side, make thread 30 by dead ring 29, next, making threadiness The engaging receiving portion 33 of the linking part 32 of object 30 and the base end part 23 of clamp body 21 link.Specifically, if by linking part 32 Convex shaped part 33B insertion be set to hold component 24 holding section 25 (pawl 26) between, then in the base end part 23 of clamp body 21 In, opposed holding component 24 is mobile to the direction being separated from each other.That is, between expanding holding component 24 by linking part 32 The base end part 23 of gap, clamp body 21 is opened to the opening and closing direction of clamp body 21.At this point, by thread 30, dead ring 29 It is pressed to far side, but the amphi position end of dead ring 29 is contacted with the protrusion 7A of the abutting part 6 as far side, is able to suppress The undesigned movement of dead ring 29.If dead ring 29 is in holding section 25 of the inside of dead ring 29 comprising clamp body 21 Mode is mobile, then distance of minimum separation (the engaging of the base end part 23 on the opening and closing direction of base end part 23 held between component The distance of minimum separation in portion 25) it expands with being unable to fully, so that holding section 25 can not link with linking part 32.

As shown in Figure 10, it if keeping thread 30 mobile to far side, is further expanded by convex shaped part 33B and holds component 24 gap.

As shown in figure 11, if keeping thread 30 further mobile to far side, holding section 25 (pawl 26) crosses convex shaped part Both the part as maximum outside diameter of 33B, pawl 26 are engaged with positioned at than convex shaped part 33B by the openings 33A of proximal side, thus Engaging.

As described above, clamp box 1 of the invention contacts the shifting for preventing dead ring 29 by abutting part 6 with dead ring 29 It is dynamic, therefore the amphi position end of dead ring 29 can be configured to the proximal side of clamp body 21.Therefore, be able to suppress dead ring 29 to The case where peri position end than clamp body 21 surrounds base end part 23 of clamp body 21 by far side movement, clamp body 21 Base end part 23 is not by the internal diameter restrictions of dead ring 29, to be easily opened.It is easy to link the linking part 32 of thread 30 as a result, In the base end part 23 of clamp body 21.

In clamp box 1, the base end part 23 of clamp body 21 is difficult to be covered by dead ring 29.Thus, for example such as Fig. 8~figure Shown in 11, at least one party in components 24 is held at 2 and is provided with to opposed 24 side of holding component holding section 25 outstanding, In the case that linking part 32 is provided with the engaging receiving portion 33 engaged with the holding section 25 of clamp body 21, following A₂And R₁It is preferred that Meet (3) formula below.

A₂< R₁ (3)

Wherein, A₂For holding section 25 with engage opening and closing direction in the state that receiving portion 33 does not engage, in base end part 23 On base end part 23 hold component 24 between distance of minimum separation, R₁For the maximum outside diameter for engaging receiving portion 33.As a result, can Enough firmly connection clamp body 21 and thread 30, therefore linking part 32 is difficult to fall off from holding section 25.

In addition, above-mentioned A₂With above-mentioned R₁More preferably meet (4) formula below.

0.13≤(A₂/R₁)≤0.50 (4)

Thereby, it is possible to more firmly connection clamp body 21 and threads 30.

In the case where the linking part 32 of thread 30 has engaging receiving portion 33,2 holding components 24 of base end part 23 Maximum separation when, subbase end 23 opening and closing direction on base end part 23 maximum length L₄It is preferred that by formula table below Show.

L₄=(L₃+R₁)-A₂

Wherein, L₃For holding section 25 with engage opening and closing direction in the state that receiving portion 33 does not engage, in base end part 23 On base end part 23 maximum length, and be L₃> A₂.The structure that the base end part 23 of clamp body 21 is opened is formed in this way, Thus even the distal end section of thread 30 is bigger size, also can firmly link clamp body 21 and thread 30。

L₃< R₂ (5)

L₄> R₂ (6)

Wherein, R₂For the internal diameter of dead ring 29.For such pincer system, holding section 25 with engage receiving portion In the state that 33 do not engage, base end part 23 is by dead ring 29, and in 2 maximum separations for holding component 24, base end part 23 is not Pass through dead ring 29.Setting L in this way is provided₃, thus make dead ring 29 mobile from base end part 23 to 22 side of handle part, thus fasten Ring 29 can close the handle part 22 of clamp body 21.In addition, setting L as described above₄, the thus base end part of clamp body 21 23 are more than the internal diameter of dead ring 29 and significantly open, therefore are easy the linking part 32 of thread 30 being linked to clamp body 21 Base end part 23.

Abutting part 6 be preferably from insertion access 3 inner surface protrusion outstanding (for example, in attached drawing 7,7A, 7B).It is prominent The portion of rising is formed as compared with surrounding part, prominent from the space of inner surface to the insertion access 3 of insertion access 3.Protrusion It is abutted with dead ring 29, thus, it is possible to prevent the movement of dead ring 29.The movement of dead ring 29 is contacted and prevented with dead ring 29 Abutting part 6 in addition to being that it is logical to be also possible to be set to aftermentioned insertion other than the inner surface protrusion outstanding of insertion access 3 The recess portion 8 of the inner surface on road 3.In the case where dead ring 29 is embedded in and is accommodated in recess portion 8, the amphi position end and recess portion of dead ring 29 Wall surface contact, the movement of dead ring 29 can be prevented.Protrusion is illustrated using Figure 12~Figure 14.

As long as the height of protrusion is formed as the linking part in the part linear object 30 for the protrusion for being provided with insertion access 3 32 by insertion access 3, and height is not particularly limited, but section of the protrusion preferably not reach insertion access 3 Center (or center of gravity) height mode it is prominent from insertion 3 inner surface of access.

As shown in Figure 12~Figure 14, protrusion is preferably made of amphi position side projecture part 7A and peri position side projecture part 7B, remote Ring incorporating section 5 is configured between the side projecture part 7A and peri position side projecture part 7B of position.The court of amphi position side projecture part 7A and dead ring 29 It is abutted to the face of 4 side of clamp body incorporating section, therefore prevents dead ring 29 mobile to the far side of insertion access 3.In addition, peri position Side projecture part 7B is abutted with the face towards 2 side of insert port of dead ring 29, therefore prevents dead ring 29 to the peri position of insertion access 3 Side is mobile.

(it is paper up and down direction in Figure 12~Figure 13, hangs down in Figure 14 for paper in the width direction for holding component 24 Histogram to) on, the length of protrusion is not particularly limited, for example, as shown in figure 12, the outer diameter of dead ring 29 can be longer than, As shown in figure 13, the outer diameter of dead ring 29 can also be shorter than.In order to reliably prevent the movement of dead ring 29, preferably in handle part In the width direction of part 24, protrusion is longer than the thickest of dead ring 29.

Amphi position side projecture part 7A and peri position side projecture part 7B are able to that one or more is arranged.In this case, far Position side projecture part 7A and the quantity of peri position side projecture part 7B may be the same or different.It is amphi position in Figure 12~Figure 14 Side projecture part 7A is provided with 2, and peri position side projecture part 7B is provided with 1.In this way, multiple amphi position side projecture part 7A are preferably provided with, And a peri position side projecture part 7B is only set.When using clamp box 1, thread 30 is inserted into from insert port 2 towards far side, And after linking the base end part 23 of clamp body 21 and thread 30, it unloads lower clamp box cover 16 (aftermentioned), to being equipped with the one of cover Thread 30 is picked up in side, thus unloads clamp body 21 from clamp box 1.Thread 30 is mobile generally toward far side in this way, Therefore compared with a possibility that proximally side is mobile for dead ring 29, follow the linking part 32 of thread 30 to far side it is mobile can Energy property is higher.Therefore, multiple protrusions are set in far side in advance, thus, it is possible to reliably prevent the movement of dead ring 29.

Amphi position side projecture part 7A and the height of peri position side projecture part 7B may be the same or different.Especially, it is being inserted into Radially, preferably amphi position side projecture part 7A is more protruded inwardly access 3 than peri position side projecture part 7B.Dead ring 29 is difficult as a result, With mobile to far side.Here, the height of protrusion refers to from the section of the inner surface direction insertion access 3 of insertion access 3 Length on the direction at center (or center of gravity).The radial inside of insertion access 3 refers to from the wall surface of insertion access 3 towards center Direction.

In the section of insertion access 3, in the case where multiple amphi position side projecture part 7A are arranged, an amphi position side projecture part 7A and others amphi position side projecture part 7A are also configurable to using the center for the section for being inserted into access 3 as the rotational symmetry of center axis Structure.29 abutting portion 6 of dead ring balancedly supports as a result, therefore even if thread 30 is inadvertently contacted with dead ring 29, Also the movement of dead ring 29 can be prevented.In addition, the case where multiple peri position side projecture part 7B are arranged can also configure in the same manner.

The height of protrusion can be constant on the extending direction of insertion access 3, can also change.Protrusion can also be with It is formed with the inclined surface increased towards far side or proximal side.It preferably wraps the inclined surface for being set to amphi position side projecture part 7A The face at the peri position end containing protrusion.Thereby, it is possible to abut protrusion with dead ring 29, and protrusion and dead ring 29 it Between gap is set, therefore be easy ring incorporating section 5 configure dead ring 29.In addition, in Figure 12~Figure 13, in amphi position side projecture part 7A is provided with inclined surface.

In the case where multiple amphi position side projecture part 7A are arranged, preferably multiple amphi position side projecture part 7A are configured to logical to be inserted into The center (center of gravity) on road 3 is the structure of the rotational symmetry of center axis.The linking part 32 of thread 30 is embedded in amphi position lateral process as a result, Portion 7A, linking part 32 are configured at angle appropriate, position relative to the clamp body 21 for being accommodated in clamp body incorporating section 4.Cause This, can reliably carry out the connection of clamp body 21 Yu thread 30, can prevent maloperation.

The inclined surface of protrusion can be formed as tilting in a linear fashion, can also be formed as inclining in a manner of curve Tiltedly.Inclined surface, which is for example preferably formed into, has 20 ° or more and 60 ° of angles below relative to the extending direction of insertion access 3.Incline Inclined-plane can also be multiple relative to a protrusion setting, can suitably be changed according to the shape of the dead ring 29 of abutting.

In addition, in order to which clamp box 1 is easily manufactured, protrusion can also be formed relative to the inner surface for being inserted into access 3 It is ladder-like.

The position for the protrusion being inserted on the extending direction of access 3 is not particularly limited, for example, it may be more logical than insertion The position of proximal side is leaned at the center of the extending direction on road 3, is also possible to by the position of far side.As long as protrusion is set to than inserting The position of proximal side is leaned at the extending direction center for entering access 3, even if then dead ring 29 is mobile to far side, it is also difficult to reach clamp Main body incorporating section 4.As long as protrusion is set to the position for leaning on far side than the extending direction center for being inserted into access 3, dead ring 29 are difficult to fall off from insert port 2.

Clamp box 1 can be made of 1 component, can also be made of 2 or more components.In addition, clamp box 1 is in inside It is formed with insertion access 3 and clamp body incorporating section 4, from making to be formed from the viewpoint of above structure becomes easy, preferred clamp Box 1 is made of component more than at least two.For example, clamp box 1 can also be by clamp box main body 15 and clamp box cover 16 this 2 Component is constituted.Clamp box main body 15 has the 1st slot of insertion 3 formation of access and the 2nd of 4 formation of clamp body incorporating section Slot covers clamp box main body 15 by clamp box cover 16, is thus respectively formed clamp body incorporating section 4 and ring incorporating section 5.This Outside, by clamp box cover 16 cover insertion 3 formation of access the 1st slot, it is possible thereby to be formed with insert port 2, insertion access 3, Clamp body incorporating section 4 and ring incorporating section 5, the clamp box main body 15 that the slot of insert port 2 can also be additionally formed at.If this Sample constitutes clamp box 1, then being made for clamp box 1 becomes easy, and installs clamp master in clamp box 1 in addition, can easily be done Body 21 takes out the gripping mechanism 40 that thread 30 is linked to clamp body 21 from clamp box 1.

As long as clamp box cover 16 covers a part of clamp box main body 15, such as by can be relative to clamp box main body The component of 15 slidings is constituted.As long as clamp box cover 16 can cover clamp box main body 15 insertion 3 formation of access the 1st slot with 2nd slot of incorporating section formation, then its shape is not particularly limited.In FIG. 1 to FIG. 2, cylinder is formed as with clamp box cover 16 Shape and the extending direction to be inserted into access 3 are constituted clamp box 1 in the way of surrounding clamp box main body 15 as axis.In addition it is also possible to structure Be formed as plate as clamp box cover 16, it is Chong Die with clamp box main body 15.The face opposed with clamp box main body 15 of clamp box cover 16 It can be formed as plane, the 2nd slot of the 1st slot and 4 formation of clamp body incorporating section that are inserted into 3 formation of access can also be formed In clamp box cover 16.

As shown in Figure 12~Figure 13, abutting part 6 can be set in the 1st slot of clamp box main body 15, also can be set in The face (not shown) opposed with clamp box main body 15 of clamp box cover 16.Thereby, it is possible to simplify the structure of clamp box 1.In addition, supporting Socket part 6 also can be set in the component different from clamp box main body 15 and clamp box cover 16.

It although not shown, but in abutting part 6 is the face opposed with clamp box main body 15 protrusion outstanding from clamp box cover 16 In the case where portion, one or more is also can be set in protrusion.The protrusion for being set to cover is configured to and is set to clamp box Protrusion in 1st slot of main body 15 is identical.In addition, clamp box cover 16 can also be installed on clamp box main body 15 by protrusion In the state of, the opposed with clamp box main body 15 of clamp box cover 16 is set in a manner of abutting with the outer peripheral surface of dead ring 29 Face.Even if pressing the outer peripheral surface of dead ring 29 by protrusion, extension of the dead ring 29 to insertion access 3 thus can be also prevented The movement in direction.

As shown in Fig. 2, protrusion 16A also can be set in the face opposed with clamp box main body 15 of clamp box cover 16 and made For the protrusion of the abutting part 6 of the movement for preventing clamp body 21.The shape of protrusion 16A is for example also possible to round, ellipse The polygons such as circle, rectangle, triangle or these combination.In Fig. 2, protrusion 16A is formed as storing to clamp body The rectangle that the far and near direction in portion 4 integrally extends, but the shape of protrusion 16A is not particularly limited.

Protrusion can also be formed to unload from insertion access 3.Such as in Figure 14, amphi position side projecture part 7A is formed In the limiting component 17 of the direction of insertion of limitation linking part 32, limiting component 17 is formed to slide upwards.Protrusion It unloads and refers to from 3 inner surface of insertion access of clamp box 1 and unload protrusion, protrusion or the component (example for being provided with protrusion Such as limiting component 17) it can be separated from clamp box 1, protrusion or the component for being provided with protrusion can also be can slide Mode is configured at clamp box 1.So long as protrusion is formed, then after linking thread 30 and clamp body 21, will press from both sides Clamp device 40 from clamp box 1 take out when, even if gripping mechanism 40 is hooked to protrusion, can also unload protrusion, thus, it is possible to from Clamp box 1 easily takes out gripping mechanism 40.In addition, can also be unloaded in advance when taking out gripping mechanism 40 from clamp box 1 Protrusion.Protrusion (amphi position when the clamp box main body 15 shown in Figure 14 is equipped with clamp box cover 16, on limiting component 17 Side projecture part 7A) it is configured to prominent from the inner surface of insertion access 3, thus, it is possible to limit limiting component 17 by clamp box cover 16 Movement.

For protrusion, the linking part 32 of thread 30 when thread 30 is inserted into insertion access 3, can also be made and dashed forward The portion of rising contact, thus thread 30 is pivoted, so as to angle, the position etc. for controlling linking part 32.Protrusion can be simultaneous There is the function of the storage of dead ring 29 and the axis rotation both sides of thread 30, the structure of clamp box 1 can be simplified, thus preferably.

Using Figure 15~Figure 16, the example that abutting part 6 is recess portion 8 is illustrated.Figure 15 expression is configured in clamp box 1 The state of dead ring 29, Figure 16 indicate the state that dead ring 29 has been unloaded from clamp box 1.Abutting part 6 or be set to it is slotting Enter the recess portion 8 of the inner surface of access 3.In this case, dead ring 29, the inner wall of dead ring 29 and recess portion 8 are stored in recess portion 8 It abuts, thus, it is possible to prevent movement of the dead ring 29 to the extending direction for being inserted into access 3.

In order to store dead ring 29, on the extending direction of insertion access 3, recess portion 8 is formed as being longer than dead ring 29.Recess portion 8 depth capacity D (towards the height of the radial outside of dead ring 29 on the basis of the inner surface for being inserted into access 3) is preferably greater than tight Gu the wall thickness of ring 29.Thereby, it is possible to reliably prevent the movement of dead ring 29.

As shown in Fig. 6~Fig. 7, it is outer greater than the minimum of holding section 25 also to could be formed with outer diameter in the proximal side of linking part 32 The wall thickness 36 of diameter.In the case where linking part 32 is provided with wall thickness 36, the depth capacity D of recess portion 8 preferably satisfies following Formula.

D < (R₃- R₄)
