Description

  The present invention relates to a work bar mounting tool, and more particularly to a work bar that can be used for various operations by attaching and detaching a functional tool according to a work target.

  Conventionally, Yatsuko that can grip a work object at a remote position is known. For example, the so-called indirect hot wire method, which works so that there is no risk of electric shock coming in direct contact with a voltage-applied electric wire, is often used, and a protective tube is put on the electric wire built on the power pole. In addition, there are operations such as screwing an insulator to an electric wire and removing a nest of crows nested on the upper part of the utility pole.

  For example, as shown in FIG. 10, a gripping unit 110 that grips a work object, an operation unit 120 that is operated by an operator, and the operation unit 120 that is disposed on the hand side are gripped. A support transmission unit 130 that is connected to the distal end positions at which the unit 110 is spaced apart and supports each of the unit 110 and transmits the operation force from the operation unit 120 to the gripping unit 110 and operates. Since the support transmission unit 130 is made of a member made of plastic or the like, insulation between the grip unit 110 and the operation unit 120 is ensured. In addition, umbrella cover 414, 142 which shows the limit position where the water | moisture content from the holding | grip part 110 side can be dripped, or can operate | work safely is supported on this Yatco 100 by the support transmission part 130 (the support bar 131 and the transmission bar 132 mentioned later). Is provided.

  The grip portion 110 of the YATCO 100 includes a stationary member (rotating member) 111 fixed to the support rod 131 of the support transmission portion 130 and a rotation shaft disposed on the support rod 131 side of the support transmission portion 130. 113, a movable member (rotating member) 112 supported so as to be rotatable about the center 113, and the movable member 112 of the grip portion 110 is connected to the operation portion 120 via the transmission rod 132 of the support transmission portion 130. It is connected to the lever 121. As a result, the gripping part 110 of the YATCO 100 is pulled by the lever 121 of the operation part 120 through the transmission rod 132 of the support transmission part 130, so that the movable member 112 is relative to the stationary member 111. By rotating to each other, the respective front end portions come in contact with each other, and the work object can be grasped or separated (see, for example, Patent Documents 1 to 3). In addition, it has also been proposed to improve functionality by attaching a nipper or the like used for general work to the tip of the gripping portion (see, for example, Patent Document 4).

  Also, the indirect hot wire method is applied to a wide variety of work, and a functional tool that functions to perform the work more efficiently than Yatco is used as an operation stick (working stick) that ensures insulation. It is also used frequently.

  As this type of operation rod, for example, as shown in FIG. 1, a rod-like portion 11 held by an operator and an attachment / detachment portion 12 for attaching / detaching various functional tools on the tip side of the rod-like portion 11 are provided. In this operation rod 10, the functional tool attached to the attaching / detaching portion 12 is replaced with a tool suitable for general work such as a saw or a hook, or a fuse cylinder in a cylindrical cutout is replaced. By exchanging with one suitable for the above, it is possible to perform a work by applying a desired operation to the work object (see, for example, Patent Documents 5 and 6).

However, in such an indirect hot line method, it is effective for carrying out the work comfortably by carrying a Yatco together with the operation rod to which various functional tools are attached and appropriately using it according to the work contents. The wire method often involves climbing to high places such as utility poles, and it is difficult to bring the Yatco together with the operating rod. Also, this Yatco is an expensive tool, so it is difficult to equip all work vehicles.

  Therefore, the present invention makes it possible to work at high places comfortably and inexpensively by making the operating rod (working rod) usable as a Yatco, and to improve the convenience of the working rod. The purpose is to provide.

  A first invention of a working rod mounting tool that solves the above-described problem has a rod-shaped portion that is gripped by an operator, and an attachment / detachment portion that is disposed on the distal end side of the rod-shaped portion and attaches and detaches various functional tools. A mounting tool to be attached to a work rod that applies a desired operation to the work object by exchanging the functional tool of the attachment / detachment portion on the distal end side according to the work content, and is attached to the attachment / detachment portion on the distal end side of the work rod A function part that is attached and functions, an operation part that is attached to and operates the bar-like part of the work bar, and a transmission part that is coupled to the operation part and the function part and transmits an operation force applied to the operation part to the function part These are provided.

  In the present invention, a functional unit is attached to a work bar that is operated in a state where the functional tool is attached and held at the tip, and an operation unit is attached to a part gripped by the operator, and the functional unit and The operation unit is connected by a transmission unit to enable operation. This allows you to attach the function unit, operation unit, and transmission unit to the work bar that only works by causing the function tool on the tip side to function by moving forward and backward, left, right, up and down, and rotating. Tools that can be operated can be assembled from the operation unit. Therefore, in addition to the function as a work bar, it is possible to perform a desired work by operating the function unit on the distal end side from the operation unit at hand on the work object at a remote position, and the function unit is replaced as appropriate. It is possible to perform various and various work.

  In addition to the specific matter of the first invention, the second invention of the working bar mounting tool that solves the above-mentioned problems is that the functional part is rotated relatively around the rotation axis and the tip part is in contact. A pair of rotating members that perform a desired operation by being separated, and the operation unit includes a lever that is pivotally supported in a direction that contacts and separates from the rod-shaped part around the rotation axis; The transmission unit includes a connecting rod that connects one rotating member of the functional unit and the lever of the operation unit, so that the connection rod of the transmission unit moves substantially parallel to the work rod by the rotation of the lever of the operation unit. Then, by rotating the rotating member of the functional unit, the distal end portions of the pair of rotating members are brought into contact with and separated from each other to perform a desired operation.

  In this invention, by rotating the lever of the operation part attached to the hand of the work bar, the connecting bar of the transmission part is moved substantially parallel to the bar-like part of the work bar, and the functional part at the tip of the work bar is moved. The rotating member can be relatively rotated so that the tip portions thereof can be contacted and separated. Thereby, a work object can be grasped between the front-end | tip parts of the rotation member of the function part of a front end side. Therefore, in addition to being used as a work bar (so-called operation bar) that functions by moving back and forth, right and left, up and down and rotating, it can also be used as a so-called Yatsuko.

  According to a third aspect of the working bar mounting tool for solving the above-mentioned problems, in addition to the specific matter of the second aspect, the functional portion is at least one in a direction in which the tip portions of the pair of rotating members approach or separate from each other. An urging means for urging the rotating member is arranged.

  In the present invention, at least one of the rotating members of the functional part that can be relatively rotated at the tip of the work bar is biased in a direction in which the rotating member approaches or separates toward the other side. Thereby, the rotation member of the function part can return to the natural state of approaching or separating from each other unless the lever of the operation part is operated. Therefore, it is possible to perform operations such as grasping or expanding the work object only by performing an operation of rotating the lever of the operation unit in one direction by bringing the tip of the rotating member closer to the work object. After this, it is possible to easily return to a state where the next operation can be performed by releasing the lever and releasing the grasped object.

  In addition to the specific matters of the second or third invention, the fourth invention of the working bar mounting tool that solves the above-mentioned problems is the connection of the rotation member of the functional unit, the lever of the operation unit, and the transmission unit. The connecting portion with the rod is characterized by having a joint structure that can be detached by being pushed with a force of a predetermined level or more and can be detached by pulling with a force of a predetermined level or more. .

  In this invention, it can be attached and detached by pressing or pulling the connecting rod of the transmission portion with a certain amount of force to the rotating member of the functional portion attached to the work rod and the lever of the operation portion. Thereby, the connecting rod of the transmission unit can be connected to the rotating member of the functional unit and the lever of the operation unit without using special parts or tools such as screws and drivers, for example. Therefore, it can be easily used as a so-called Yatsuko simply by carrying the rotating member of the functional unit, the lever of the operation unit, and the connecting rod of the transmission unit together with the work rod.

  According to a fifth aspect of the working bar mounting tool for solving the above-mentioned problems, in addition to the specific matters of any one of the second to fourth aspects, the connecting bar of the transmission portion is substantially parallel to the bar-shaped portion of the working bar. It has a holding member that holds it in a proper posture.

  According to the present invention, the connecting rod of the transmission portion connected to the rotating member of the functional portion at the tip of the working rod and the lever of the operating portion is held in a posture substantially parallel to the rod-shaped portion of the working rod by the holding member which is a separate part. Can be made. Thereby, even if it does not make it the state connected with the rotation member of a function part, for example, it can hold | maintain, without connecting the connecting rod of a transmission part, from a work stick. Therefore, the functional unit can be removed from the tip of the work bar and replaced with another functional tool with the lever of the operation unit and the connecting rod of the transmission unit attached to the work bar, and can be used as a work bar as it is. Can do.

  As described above, according to the present invention, the functional unit is attached to the work bar for performing a desired work by exchanging the functional tool at the tip and moving forward and backward, right and left, up and down, and rotating, and the operation unit and By simply attaching the transmission part, the function part at the tip can be operated by hand to perform a desired work operation on the work object at a remote position. For example, a pair of rotating members can be attached as the function part to operate the operation part. By operating the lever, the tip end portion of the rotating member is brought into contact with and separated from, so that the working rod can be used as a lever.

  Therefore, for example, even in a work place such as a high place where it is bulky and cannot carry the YATCO with the work rod, it is cheap and easy to carry the YATCO with the work rod and the functional tool together with the parts such as the functional unit and the operation unit. As a result, the convenience of the work bar can be improved and the work can be comfortably performed.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described based on the drawings. FIGS. 1-9 is a figure which shows an example at the time of attaching one Embodiment of the mounting tool for working bars which concerns on this invention to a working bar, and assembling the Yatco.

  In FIG. 1, an operation rod 10 includes a rod-like portion 11 that is formed in a long shape and is gripped by an operator, and an attachment / detachment portion 12 that is disposed on the distal end side of the rod-like portion 11 and attaches / detaches various functional tools. In addition, by bringing a functional tool such as a hook attached to the detachable portion 12 by gripping the rod-shaped portion 11 by an operator close to a work object at a remote position, for example, a desired work / operation can be performed on an electric wire or the like at a high place. A so-called indirect hot wire method can be realized.

  For example, the operation stick 10 can be used for the indirect hot wire method by attaching the CF attachment (functional tool) 20 shown in FIG. 2 to the attaching / detaching portion 12. The CF attachment 20 is installed at a high place such as a utility pole. The operation of attaching and detaching the fuse cylinder 32 can be easily and safely performed in the main body 31 of the cylindrical cutout 30 shown in FIG.

  For example, the rod-shaped portion 11 is made of an insulating material such as plastic in a hollow cylindrical shape so that insulation is secured, and umbrella covers 13 and 14 are attached to intermediate portions between both ends, When the umbrella cover 13 drops water from the detachable portion 12 side, and the umbrella cover 14 on the base end side indicates the limit position where the work can be safely performed in consideration of the insulation from the distal end side. Ensuring safety. In addition, the part which the operator of the rod-shaped part 11 hold | grips is provided with the slipper which can replace the material which is hard to slip.

  The detachable portion 12 includes a main body shaft portion 15 protruding in the same direction as the rod-shaped portion 11, a pair of pins 16 erected in a protruding shape on opposite sides of the peripheral surface of the main body shaft portion 15, and a main body A protrusion 17 urged by a built-in spring (not shown) so as to protrude from the tip surface of the shaft portion 15 and a screw shape (not shown) engraved on the peripheral surface of the body shaft portion 15 on the rod-like portion 11 side. A grip 18 that moves up and down together is disposed.

  The CF attachment 20 to be attached to the detachable portion 12 includes a joint portion 21 designed to engage and lock the detachable portion 12 so that it cannot be rotated relative to the detachable portion, and cannot be detached. The main body cylindrical portion 22 formed in a bottomed cylindrical shape with the base end side rear end surface opened so that the main body shaft portion 15 of the portion 12 can be inserted and received, and the peripheral surface portion of the main body cylindrical portion 22 are mutually connected. It is comprised by a pair of T-shaped notch part 23 which is located in the other side and is notched by the general | schematic T-shape. Here, in detail, the T-shaped notch portion 23 extends to both sides of the insertion groove portion 23a from the rear end surface side to the front end side of the main body cylindrical portion 22 and the insertion groove portion 23a in the orthogonal direction. The rotating groove 23b is formed in a T-shape with a rotating groove 23b and an engaging groove 23c that returns from both ends of the rotating groove 23b to the rear end surface side of the main body cylinder 22.

  Thus, the joint portion 21 of the CF attachment 20 allows the body of the detachable portion 12 to be inserted while the pin 16 of the detachable portion 12 of the operating rod 10 is inserted into the insertion groove portion 23a of the T-shaped notch portion 23 of the main body cylindrical portion 22. After the shaft portion 15 is inserted into the inside of the main body cylindrical portion 22, the shaft portion 15 can be caused to enter until it abuts against the end portion of the rotation groove portion 23 b of the T-shaped notch portion 23 by rotating relative to each other. At this time, the main body shaft portion 15 of the detachable portion 12 abuts against the bottom surface of the main body cylinder portion 22 of the joint portion 21 and relatively rotates with the projection 17 sinking, and then the force inserted into the main body cylinder portion 22 is released. Then, the projection 17 protrudes due to the elastic force of the built-in spring and pushes back the main body cylindrical portion 22, and the pin 16 of the detachable portion 12 enters the engaging groove portion 23 c from the rotating groove portion 23 b of the T-shaped notch portion 23. Thus, it is possible to engage with each other so that the relative rotation is impossible and the separation is impossible. Further, the operating rod 10 can be locked so that the pin 16 is not detached from the engaging groove 23c and rotated by rotating the grip 18 of the attaching / detaching portion 12 and moving it toward the joint portion 21 side. It is possible to reliably prevent the joint portion 21 of the attachment 20 from being relatively rotated and detached from the attaching / detaching portion 12 of the operation rod 10.

  Further, the CF attachment 20 has a holding portion 24 formed in a substantially cylindrical shape that opens a lower portion 32a of a fuse cylinder 32 that is detachably attached to the main body portion 31 of the cylindrical cutout 30 so that the lower portion 32a can be accommodated. In the state in which the lower portion 32a of the fuse cylinder 32 is accommodated in the holding portion 24, it is engaged in a non-detachable manner by an engagement mechanism (not shown) The lower part 32a of the fuse cylinder 32 is designed to be releasably released by relative rotation in the opposite opposite direction.

  As a result, the CF attachment 20 opens the fuse cylinder 32 in a state in which the lower portion 32a is engaged with the holding portion 24 in a direction that is relatively rotated in one direction, and is opened to the lower portion of the main body portion 31 of the cylindrical cutout 30. It can be inserted and set through the insertion port 33, and the space between the power connection part 36 and the load connection part 37 of the cylindrical cutout 30 is electrically connected via a fuse (not shown) built in the fuse cylinder 32. The electric wire D1 branched and connected from the electric wire on the commercial power supply side can be conductively connected to the electric wire D2 on the load device side. The CF attachment 20 is inserted into the main body 31 from the insertion port 33 of the cylindrical cutout 30 with the closing lid 34 removed, and the lower portion 32 a of the fuse cylinder 32 is accommodated in the holding portion 24. The fuse cylinder 32 can be lowered so as to be pulled out from the insertion port 33 and can be detached after being relatively engaged in one direction by being rotated, and the power supply connection of the cylindrical cutout 30 can be performed. The conduction connection between the portion 36 (the electric wire D1) and the load connecting portion 37 (the electric wire D2) can be interrupted.

  Further, the closing lid 34 for closing the insertion port 33 of the main body 31 of the cylindrical cutout 30 is pressed against the insertion port 33 in a posture in which the cylindrical portion 34a is directed outward (lower side), whereby the insertion port 33 is pressed. The leaf springs 35 installed at a plurality of locations on the inner peripheral surface of the outer edge side of the outer edge of the insertion spring 33 can be spread and held so as not to fall. Can be spread out and released. The closing lid 34 is connected to the other end side of a hanging strap 38 fixed at one end to the main body 31 of the cylindrical cutout 30 and may be dropped and lost by the hanging strap 38. In addition to being prevented, it can be easily removed from the insertion port 33 by pulling the hanging strap 38. Here, the closing lid 34 of the cylindrical cutout 30 is in a state in which the cylindrical portion 34a is inserted and held inside the holding portion 24 (inside the cylindrical shape) of the CF attachment 20 (the cylindrical portion 34a is lowered below). It can be attached by pressing against its insertion port 33 (in a side-to-side orientation).

  And the mounting tool which consists of each part shown in FIGS. 4-8 is prepared for the operating rod 10 so that attachment is possible, and this mounting tool is attached to the attachment / detachment part 12 of the operating rod 10, and performs desired operation | movement.

The holding member 70 is configured to be held in a posture substantially parallel to the rod-like portion 11 of the operation rod 10 so that the transmission mounting tool 60 does not become unstable.

  As shown in FIG. 4, the function wearing device 40 is designed to be detachable from the attaching / detaching portion 12 of the operation rod 10 by providing the joint portion 21, as in the case of the CF attachment 20. A set of two immovable members (rotating members) 41 erected on the front end surface of the portion 22, and an intermediate portion sandwiched between the immovable members 41 is rotatably supported by a rotating shaft 42. Both ends are connected between the movable member (rotating member) 43 and the distal end side of the movable member 43 with respect to the rotating shaft 42 and the distal end surface of the main body cylinder portion 22, and the distal end portion 43 a of the movable member 43 is connected. And a spring (biasing means) 44 that pulls (biases) in a direction away from the distal end portion 41a of the immovable member 41. The stationary member 41 and the movable member 43 of the functional wearing device 40 are bent in a direction in which the distal end portions 41a and 43a approach each other, and in the natural state where the distal end portions 41a and 43a are sufficiently pulled by the spring 44, The work object etc. can be inserted between them with the distance 43a separated, and when the tip portions 41a, 43a approach, the work object existing between them can be grasped.

  As shown in FIG. 5, the operation mounting tool 50 is formed so as to be along the outer peripheral surface of the rod-shaped portion 11 of the operation rod 10, and has a flat plate shape in which arc portions 51 a sandwiching the rod-shaped portion 11 face each other. And a lever 52 that is formed in a “<” shape and is pivotally supported at one end of the clamping member 51 so as to be pivotable. One end side of the clamping member 51 is designed to adjust the facing distance by passing a bolt 53 a through a screw hole (not shown) and screwing a nut 53 b, and the bolt 53 a is attached to a bent portion of the lever 52. It is pivotally supported by passing through a through hole (not shown) that is opened and adjusting the facing distance so as not to limit the rotation of the lever 52. In addition, the other end side of the clamping member 51 has a screw hole (not shown) that can pass through the bolt 54a in the same manner as the one end side, but the bolt 54a is inserted / removed from the end side to the other side. A notch portion 51b that expands as much as possible is formed. The wing nut 54b is screwed into the bolt 54a and pressed on both sides of the notch portion 51b, whereby the other end side of the clamping member 51 is tightened to The outer peripheral surface of the rod-shaped part 11 can be pinched by the circular arc part 51a, and it can attach so that a movement is impossible. The lever 52 has a rubber 55 wound on one end side for the purpose of protecting the hand of the operator.

  As shown in FIG. 6, the transmission attachment 60 is provided with insulation by a body portion (connecting rod) 61 formed of an insulating material such as plastic in a hollow cylindrical shape, for example, in substantially the same manner as the rod-like portion 11. The main body 61 is made to have a length capable of connecting the function mounting tool 40 attached to the operation rod 10 and the operation mounting tool 50. An umbrella cover 63 is attached to the main body portion 61 at a position corresponding to the umbrella cover 13 of the rod-shaped portion 11, and the umbrella cover 63 is similarly connected from the distal end side (the attaching / detaching portion 12 side of the operation rod 10). Water is dripped to ensure safety when working.

  In addition, a receiving portion 62 formed in a substantially cylindrical shape is fixed to both ends of the main body portion 61 of the transmission mounting device 60, and the rear end portion 43 b of the movable member 43 of the functional mounting device 40 and the operation mounting device are mounted. The other end 52 a of the lever 52 of the tool 50 (opposite the rubber 55) is connected with plugs 46 and 56 formed in a substantially cylindrical shape so as to be plugged into the receiving part 62 of the transmission mounting tool 60. The members 47 and 57 are rotatably connected by the rotation shafts 47a and 57b. Protrusions 46a and 56a that are urged and projected by a biasing member such as a built-in leaf spring are disposed on the peripheral surfaces of the insertion portions 46 and 56, and the projections 46a and 56a are provided on the receiving portion 62. The recess shape 62a is formed at a corresponding position so as to define a space allowing the protrusion. The insertion portions 46 and 56 are formed with flange shapes 46 b and 56 b in order to limit insertion into the receiving portion 62 more than necessary.

  As a result, the rear end portion 43b of the movable member 43 of the function attachment device 40 and the other end portion 52a of the lever 52 of the operation attachment device 50 insert the insertion portions 46 and 56 into the receiving portion 62 of the transmission attachment device 60. Then, the projections 46a and 56a can be made to enter against the projection output (biasing force) by being pushed in with a predetermined force or more, and the projections 46a and 56a project in the recessed shape 62a of the receiving portion 62. As a result, it can be easily assembled without being separated unless it is pulled out with a predetermined force or more. That is, the insertion parts 46 and 56 and the receiving part 62 are designed in a joint structure. Here, since the insertion parts 46 and 56 are connected to the movable member 43 of the function mounting device 40 and the lever 52 of the operation mounting device 50 so that the posture can be freely changed by the connecting members 47 and 57, the transmission mounting device. The operation can be easily performed regardless of the posture of the movable member 43 and the lever 52 that are continuously provided when the receiving unit 62 is inserted into the receiving unit 62 of the 60.

  Therefore, as shown in FIG. 7, by attaching the operation mounting tool 50 to the rod-like portion 11, the attachment / detachment portion 12 of the operation rod 10 can be attached without using special parts and tools such as screws and drivers. The functional attachment 40 can be easily attached and detached, and the transmission attachment 60 can be easily connected to the functional attachment 40 and the operation attachment 50, and is equivalent to the YATCO 100 shown in FIG. 80 can be assembled and used at low cost.

  As shown in FIGS. 7 and 8, the holding member 70 includes a first holding portion 71 having an opening 71 a having substantially the same diameter as the rod-like portion 11 of the operation rod 10, and a body portion 61 having the same diameter as the main body portion 61 of the transmission fitting 60. The second holding portion 72 having the opening 72a is formed at both ends, and is made by molding a resin material that can be elastically deformed to some extent. The first and second holding portions 71 and 72 of the holding member 70 are set to an interval that substantially coincides with the separation distance when the rod-like portion 11 of the operation rod 10 and the main body portion 61 of the transmission mounting device 60 are parallel to each other. In addition, when the main body portion 61 of the transmission mounting tool 60 is connected to the function mounting tool 40 and the operation mounting tool 50, the main body portion 61 is located between them and is designed to be freely translatable. In addition, the first and second holding portions 71 and 72 of the holding member 70 are formed with notches 71b and 72b that are set narrower than the diameters of the rod-like portion 11 and the main body portion 61 on the same side. By pushing the rod-like portion 11 of the operating rod 10 and the main body portion 61 of the transmission fitting 60 from the notches 71b and 72b, the first and second holding portions 71 and 72 are installed in the openings 71a and 72a. Can be held. Here, a rubber material 73 is affixed to the inner surface of the first holding portion 71, and it is restricted that the first holding portion 71 rotates freely by being in close contact with the rod-like portion 11 of the operation rod 10 that is internally provided.

  Therefore, by attaching the operation mounting tool 50 and the transmission mounting tool 60 to the rod-shaped portion 11 of the operating rod 10 and holding or removing the main body 61 of the transmission mounting tool 60 from the holding member 70, the attaching / detaching portion of the operating rod 10 is provided. 12, a function tool (not shown) and a function mounting tool 40 can be attached and detached.

  For example, as shown in FIG. 9, in a state where the rod-like portion 11 of the operation rod 10 and the main body portion 61 of the transmission mounting device 60 are held in a parallel posture by the holding member 70, By attaching the attachment 20, it is possible to perform the work of attaching and detaching the fuse cylinder 32 in the cylindrical cutout 30, and thereafter, as shown in FIG. 7, the main body 61 of the transmission attachment 60 is held. By detaching from the second holding portion 72 of the member 70 and connecting it to the movable member 43 of the function wearing device 40, the operation rod 10 can be easily assembled to the YATKO 80 for work.

  In the Yatco 80, the cylindrical portion 34a of the closing lid 34 of the cylindrical cutout 30 is inserted between the stationary member 41 separated by the spring 44 of the function wearing device 40 and the distal end portions 41a and 42a of the movable member 43. After that, by grasping the rubber 55 of the lever 52 of the operation mounting device 50, the main body 61 of the transmission mounting device 60 is pulled and moved substantially in parallel to move the movable member 43 of the functional mounting device 40 with respect to the stationary member 41. The distal end portions 41a and 43a can be relatively rotated to approach each other, and as shown in FIG. 10, the cylindrical portion 34a of the closing lid 34 is held between the distal end portions 41a and 43a and has a stable posture. It can be directly attached to the insertion port 33 of the cylindrical cutout 30 by pressing (in a state where force can be applied).

  At this time, when the YATCO 80 loosens the force for gripping the lever 52 of the operation mounting tool 50, the spring 44 of the function mounting tool 40 separates the stationary member 41 and the distal end portions 41a, 42a of the movable member 43 from each other. It is possible to return to a standby (natural) state where the next operation can be started, and the cylindrical shape portion 34a of the closing lid 34 of the cylindrical cutout 30 can be separated to perform other operations continuously.

  As described above, in the present embodiment, the heavy lid 100 shown in FIG. 11 is not lifted to a high place, and is inserted into the holding portion 24 of the non-dedicated CF attachment 20 so as to remain in an unstable posture. The function mounting tool 40, the operation mounting tool 50, and the transmission are transmitted together with a simple rod-shaped operation bar 10 that does not push the cylindrical portion 34 a against the insertion port 33 of the cylindrical cutout 30 in an inferior workability. By simply carrying the mounting tool 60, the YATCO 80 can be assembled easily and inexpensively, or by using the holding member 70, it can be carried in a semi-assembled state and used as the operation rod 10 or YATCO 80. Continuing the work of setting the fuse cylinder 32 in the mold cutout 30, the closing lid 34 is stabilized at the insertion port 33 in a stable posture. It can be attached to.

  Therefore, even on an electric pole in a high place where the conventional YATCO 100 cannot be carried with the operation rod 10, the YATCO 80 can be easily and inexpensively assembled from the operation rod 10 and used with the operation rod 10. This improves the convenience of the operation rod 10.
