Description

  The present invention relates to a seat clip mounting assisting tool used when an electrical insulating insulating sheet coated with an object to be covered such as an overhead wire in a live wire state, an insulator, a metal arm or the like is sandwiched and fixed by a sheet clip, In particular, the present invention relates to a seat clip attachment assisting tool that is used when attaching a sheet clip to an insulating sheet that covers an object to be covered using an insulating jacket.

  In recent years, an indirect hot wire construction method for performing various operations on a power system in a live wire state using an indirect hot wire working tool such as an insulating Yatco or an indirect hot wire operation rod is becoming widespread. In other words, the indirect hot wire construction method performs various operations using an indirect hot wire work tool, and therefore attracts attention as being able to ensure the safety of workers without directly touching the power system in the live state. It is being adopted by power companies and construction companies nationwide.

  By the way, as described above, the indirect hot line method is effective for ensuring the safety of the worker, but in order to make the worker's safety more complete, various work on the power system in the live line state is performed. In doing so, it is a rubber or resin that has electrical insulation on some of the overhead wires that make up the power system, and on the objects around the work objects (hereinafter referred to as covering objects) such as insulators and armors that support the overhead lines. An insulation sheet made of metal is wound and the object to be covered is covered with an insulation sheet to prevent occurrence of a short circuit accident or a ground fault.

  Then, since the insulating sheet may be detached only by winding the insulating sheet around the covering object, generally, the insulating sheet is fixed by attaching a sheet clip to the insulating sheet wound around the covering object. (For example, refer to Patent Documents 1 and 2).

  As shown in FIG. 1, the seat clip includes a pair of clip members 50a and 50b that face each other, and a shaft 51 that pivotally attaches the pair of clip members 50a and 50b. The pair of clip members 50a, 50b is in a state in which one end side (hereinafter referred to as a clamping portion) 500a, 500b is close to each other, and the other end side (hereinafter, grip) from the pivot position (shaft 51) of both clip members 50a, 50b. 501a and 501b are separated from each other.

  The seat clip 5 is provided with urging means (not shown) for urging the clip members 50a and 50b so that the holding portions 500a and 500b of the clip members 50a and 50b approach each other in a normal state. Yes. As a result, the seat clip 5 having the above-described configuration urges the grip portions 501a and 501b against the urging force by the urging means so that the grip portions 501a and 501b approach each other, thereby holding the holding portions 500a and 501b. 500b can be separated from each other and the insulating sheet S wound around the covering object T can be interposed between them, and the urging force of the urging means can be released by releasing the urging force on the grip portions 501a and 501b. , 500b approach each other and sandwich the insulating sheet S.

  When the insulating sheet S is wound around the covering object T or the sheet clip 5 having the above-described configuration is attached to the insulating sheet S, an insulating Y-co Y is used as shown in FIG. That is, the winding operation of the insulating sheet S and the mounting operation of the sheet clip 5 are performed by the indirect hot wire method.

  The insulating Ytco Y is provided with a pair of sandwiching bodies P, P that can be connected to and separated from one end of a rod-like insulator B having electrical insulation, and is provided on the other end side of the insulator B. By operating a lever (not shown), the pair of sandwiching bodies P, P are brought into and out of contact with each other. Therefore, when the seat clip 5 is attached to the insulating sheet S wound around the covering object T, the grip portions 501a and 501b of the sheet clip 5 are sandwiched (biased) by the pair of sandwiching bodies P and P of the insulating jacket Y and sandwiched. A series of operations are performed in which the gripping portions 501a and 501b are released (biased) while the portions 500a and 500b are separated from each other and the insulating sheet S is interposed between the gripping portions 500a and 500b. As a result, as shown in FIG. 15B, the insulating sheet S wound around the covering target T is sandwiched between the sheet clips 5, and as a result, the covering target T is maintained in the state covered with the insulating sheet S. As a result, when the worker performs various operations thereafter, contact with the power system is reliably prevented, and the safety of the worker is ensured.

  By the way, as described above, in order to attach the seat clip 5 to the insulating sheet S, the grip portions 501a and 501b are sandwiched by the sandwiching bodies P and P of the insulating jacket Y so that the sandwiching portions 500a and 500 of the seat clip 5 are separated from each other. Therefore, depending on the arrangement and posture of the insulating sheet S to which the seat clip 5 is to be attached, the operator may operate the insulating Y-coat in an unreasonable posture, In some cases, Y may enter an environment in which it is in a live line state.

  That is, when the sheet clip 5 is attached to the insulating sheet S wound around the covering object T, the grip sheets 501a and 501b are attached until the insulating sheet S is interposed between the clamping portions 500a and 500b of the clip members 50a and 50b. Since the clamping (biasing) cannot be released, the arrangement of the insulating Y-cots Y and the seat clips 5 (the positions of each other) becomes constant during the installation work of the seat clip 5, and the position of the insulating Y-cots Y is the seat clip. 5 will be restrained.

  Therefore, an operator tries to make the posture of the sheet clip 5 correspond to the arrangement and posture of the insulating sheet S (the sheet clip 5 is arranged so that the insulating sheet S can be interposed between the holding portions 500a and 500b of the clip members 50a and 50b). As a result, the operator may operate the insulated Y-coat Y in an unreasonable posture, or the operator or the insulated Y-shaped Y may approach or intrude into a live line environment. It was pointed out that accidents, electric shocks, short circuit accidents, etc. may occur.

  Therefore, in view of such a situation, the present invention operates the insulating jacket in an unreasonable posture when the sheet clip is attached to the insulating sheet wound around the covering object, or the worker or the insulating jacket is hot. It is an object of the present invention to provide a seat clip attachment assisting tool that can prevent an approach or entry into an environment in a state and can sufficiently ensure the safety of an operator.

  In the seat clip attachment assisting device according to the present invention, a pair of clip members facing each other are pivotally attached via a shaft, and the holding portions on one end side of each clip member with the shaft as a boundary approach each other. Seat clip mounting aid used when attaching a sheet clip in which both clip members are urged by the urging means so that the grip portions on the other end side of the clip member are separated from each other to an insulating sheet coated with a covering object And a pair of grip restricting portions, a pair of grip restricting portions, and a connecting portion for connecting at least one of the one end and the other end of the pair of grip restricting portions. The grip part that is configured to be able to intervene between the grip parts that are brought close to each other, and each grip part that intervenes between the pair of grip restricting parts is opposed to each other by urging by the urging means. Characterized in that it is configured to maintain in a state of being spaced apart clamping portions of the sheet clip abuts.

  According to the seat clip attachment assisting device having the above-described configuration, the grip portions of the seat clip intervening between the grip restricting portions are brought into contact with the opposing grip restricting portions, so that they are separated from each other by the biasing means. The movement of the grip portion is restricted, and the holding portion of the seat clip can be maintained in a separated state. This eliminates the need to hold the grip portion of the seat clip with an insulating jacket to separate the holding portions of the seat clip from each other, so that an appropriate portion of at least one of the seat clip and the seat clip mounting aid is used with the insulating jacket. Can be held.

  Therefore, when the insulating sheet is interposed between the holding portions of the seat clip, the posture of the insulating clip is not restrained by the posture of the seat clip, and the operator can operate the insulating clip in an unreasonable posture. In addition, it is possible to prevent the insulating jacket from approaching or intruding into an environment in a live line state, and the safety of the worker can be sufficiently ensured.

  Then, the seat clip mounting aid having the above-described configuration is configured so that the grip restricting portion is moved in a direction opposite to the direction in which the grip portion is interposed between the grip restricting portions in a state where the grip portion is in contact with the grip restricting portion. It is possible to remove the grip part from the contact and release it. As described above, when the seat clip attachment assisting tool having the above-described configuration is removed, the holding portion of the seat clip approaches each other by the biasing means, and the insulating sheet is sandwiched. Therefore, the seat clip attachment assisting tool having the above-described configuration can be used when the operator operates the insulated lever in an unreasonable posture even when it is removed from the seat clip, or approaches an environment where the worker or the insulated jacket is in a live state. Intrusion can be prevented, and the safety of workers can be sufficiently ensured.

  As one aspect of the present invention, it is preferable that a holding protruding piece that protrudes outwardly protrudes from at least one of the grip restricting portion and the connecting portion. If it does in this way, the aspect which hold | maintains the protrusion for a holding | maintenance can be taken other than the aspect which hold | maintains a seat clip directly, and the aspect which hold | maintains at least any one of a grip control part and a connection part directly with an insulating jacket. Thereby, since the location (mode) hold | maintained with an insulating Yatco increases, it becomes easy to make the attitude | position of a seat clip respond | correspond to arrangement | positioning and attitude | position of an insulating sheet, and a seat clip can be attached more smoothly.

  As another aspect of the present invention, it is preferable that one end of the pair of grip regulating portions is connected to each other via a connecting portion, while the other end is opened. In this way, even if the seat clip and the seat clip attachment auxiliary tool are moved relative to each other in the direction in which the grip restricting portion extends in addition to the direction orthogonal to the direction in which the grip restricting portion extends, It is possible to intervene in between or to remove the seat clip attachment aid itself from the seat clip.

  In this case, it is preferable that the pair of grip restricting portions be chamfered at least on the opposite surface side of the other end. In this way, when the seat clip and the seat clip mounting aid are relatively moved in the direction in which the grip restricting portion extends to interpose the grip portion of the seat clip between the grip restricting portions, the grip portion and the grip restricting portion Interference can be mitigated. Thereby, when attaching and detaching the seat clip attachment tool to and from the seat clip, the seat clip (grip part) can be prevented from being damaged, and the grip part of the seat clip is smoothly intervened between the grip restricting parts. be able to.

  And it is preferable that the flexible wire connected with the seat clip is connected directly or indirectly to at least one of the grip restricting portion and the connecting portion. In this way, the seat clip and the seat clip mounting aid can be integrated, and the seat clip mounting aid can be integrated with the seat clip mounting aid according to the seat clip at the time of work. Can be attached to a clip. Moreover, the sheet clip holding the insulating sheet can be removed by holding and pulling the wire rod or the sheet clip attachment auxiliary tool with the insulating Yacht while the insulating sheet is sandwiched between the sheet clips.

  As described above, according to the seat clip attachment assisting tool according to the present invention, when attaching the sheet clip to the insulation sheet wound around the covering object, the operator operates the insulation jacket in an unreasonable posture, In addition, it is possible to prevent the insulating jacket from approaching or intruding into an environment in a live line state, and it is possible to achieve an excellent effect that the safety of the worker can be sufficiently ensured.

Is formed. That is, each clip member 50a, 50b is formed with sandwiching portions 500a, 500b for sandwiching the insulating sheet S on one end side, and grip portions 501a, 501b for separating the sandwiching portions 500a, 500b from each other on the other end side. ing.

  The seat clip 5 is provided with urging means (not shown) for urging both the clip members 50a and 50b so that the sandwiching portions 500a and 500b approach each other in a normal state. Here, as an urging means, a coil spring interposed between the grip portions 501a and 501b so as to urge the grip portions 501a and 501b outward, and an urging force toward the outer sides of the grip portions 501a and 501b. Thus, a torsion coil spring or the like externally fitted to the shaft 51 is employed.

  Then, as shown in FIG. 1B, the seat clip 5 configured as described above urges both the clip members 50a and 50b against the urging by the urging means so that the grip portions 501a and 501b approach each other. As shown in FIG. 1 (a), the clamping portions 500a and 500b of the clip members 50a and 50b are separated from each other by releasing the biasing force to the grip portions 501a and 501b. The holding portions 500a and 500b come close to each other by the biasing means.

  Note that the seat clip 5 shown in FIG. 1 is formed so that the holding portions 500a and 500b are curved, and when both the holding portions 500a and 500b come close to each other, only one end portion (tip portion) of each is held. Although the holding portions 500a and 500b extend substantially straight, and when both the holding portions 500a and 500b come close to each other, each of the holding portions 500a and 500b are configured to contact each other (for example, Japanese Patent Laid-Open 2001-27209 publication etc.).

  The seat clip attachment assisting tool according to the present embodiment is intended for the seat clip 5 having the above-described configuration. As shown in FIGS. 2 and 3, the pair of grip restricting portions 10 and 11 facing each other, A connecting portion 12 that connects one end portions (base end portions) of the grip restricting portions 10 and 11 is provided.

  The seat clip attachment assisting tool 1 having the above-described configuration is configured such that the grip portions 501a and 501b that are brought close to each other between the pair of grip restricting portions 10 and 11 can intervene, and intervene between the pair of grip restricting portions 10 and 11. The grip portions 501a and 501b are held in contact with the opposing grip regulating portions 10 and 11 by the urging force of the urging means so that the holding portions 500a and 500b of the seat clip 5 are maintained apart from each other. Yes. In other words, the pair of grip restricting portions 10 and 11 are arranged with an interval at which the pair of grip portions 501a and 501b can be interposed only when the pair of grip portions 501a and 501b are brought close to each other. In the present embodiment, the pair of grip regulating portions 10 and 11 are set to have the same or substantially the same length in the axial direction.

  In the seat clip attachment assisting tool 1 according to the present embodiment, the other end portions (tip portions) of the pair of grip regulating portions 10 and 11 are opened. That is, the seat clip attachment assisting tool 1 according to the present embodiment is formed in a U-shape in plan view by connecting only the base end portions of the pair of grip regulating portions 10 and 11 via the connecting portion 12. .

  Thereby, the seat clip attachment assisting tool 1 according to the present embodiment can interpose the grip portions 501a and 501b of the seat clip 5 from the front end side of the grip restricting portions 10 and 11 between the grip restricting portions 10 and 11. Further, the grip portions 501a and 501b of the inserted seat clip 5 can be extracted from the front end sides of the clip restricting portions 10 and 11. That is, the seat clip attachment assisting tool 1 according to the present embodiment causes the grip portions 501a and 501b that are close to each other (closed) to move relative to the seat clip 5 in the direction in which the grip restricting portions 10 and 11 extend. The pair of grip regulating portions 10 and 11 can be taken in and out.

  In this embodiment, each grip control part 10 and 11 is formed in prismatic shape, and is arrange | positioned so that one surface of the four surfaces which comprise the outer peripheral surface may be made to oppose. And a pair of grip control parts 10 and 11 concerning this embodiment chamfer C on the edge of the counter surface side of at least the other end part (tip part).

  That is, on the premise that each of the grip regulating portions 10 and 11 is formed in a prismatic shape, chamfering C is applied to the edge on the tip (other end) side that delimits a surface (opposing surface) facing each other, and a pair of At the other end portions of the grip restricting portions 10 and 11, the distance between the opposing surfaces increases toward the other end (tip). Accordingly, the seat clip attachment assisting tool 1 according to the present embodiment is moved relative to the seat clip 1 in the extending direction of the grip restricting portions 10 and 11, and the grip portions 501a and 501b are interposed between the grip restricting portions 10 and 11. When intervening, the interference between the grip portions 501a and 501b and the grip restricting portions 10 and 11 is alleviated, the damage to the seat clip 5 (grips 501a and 501b) is suppressed, and the grip between the clip restricting portions 10 and 11 is suppressed. The parts 501a and 501b can be smoothly intervened.

  In addition, the seat clip attachment assisting tool 1 according to the present embodiment is chamfered (numbered) with respect to an edge extending in the axial direction of the grip regulating portions 10 and 11 by defining the opposing surfaces of the grip regulating portions 10 and 11. Not). Since the contact area between the grip restricting portions 10 and 11 and the grip portions 501a and 501b is reduced by chamfering in this way, the contact resistance between the seat clip attachment assisting tool 1 and the seat clip 5 is reduced. The seat clip attachment auxiliary tool 1 can be smoothly removed from 5.

  The connecting portion 12 only needs to be able to connect the pair of grip restricting portions 10 and 11 to each other, and can be set in various forms. In the present embodiment, the connecting portion 12 is formed in a prismatic shape like the grip restricting portions 10 and 11 and has both ends. One end of the grip restricting portions 10 and 11 is connected to the portion.

  The seat clip attachment assisting tool 1 according to the present embodiment is provided with a holding protrusion 13 protruding outward from the connecting portion 12. The holding protruding piece 13 can be set in various forms. In the present embodiment, the holding protruding piece 13 is formed in a plate shape and extends along a surface perpendicular to the extending direction (axial direction) of the connecting portion 12. Is arranged. And in the protrusion 13 for holding | maintenance which concerns on this embodiment, the hole 15 for penetrating the wire 2 (refer FIG. 4) mentioned later penetrates in the surface orthogonal direction. The holding protrusion 13 is formed with a plurality of irregularities (concave and convex) (not shown) alternately as anti-slip on both surfaces in consideration of sandwiching the insulating yoke Y.

  In the seat clip mounting aid 1, the flexible wire 2 connected to the seat clip 5 is connected to at least one of the grip regulating portions 10 and 11 and the connecting portion 12. preferable. In the present embodiment, as shown in FIG. 4, the wire 2 connected to the seat clip 5 is connected to the connecting portion 12 via the holding protrusion 13. The wire 2 according to the present embodiment is formed of an electrically insulating string material (for example, a string formed of at least one of a rubber string, a natural fiber, and a synthetic fiber). The wire 2 is inserted into holes H1 and H2 formed in both grip portions 501a and 501b of the seat clip 5, and a knot is formed at one end portion thereof to prevent the grip portion 501a from coming off. . The other end of the wire 2 is inserted into the hole 15 of the seat clip mounting assisting tool 1 (holding protrusion 13), and a knot is formed at the other end so that it is removed from the seat clip mounting assisting tool 1. It is stopped.

  The seat clip attachment assisting tool 1 according to the present embodiment has the above-described configuration. Next, a method of using the seat clip attachment assisting tool 1 will be described.

  First, the seat clip attachment assisting tool 1 is attached to the grip portions 501a and 501b in a state where the operator holds the grip portions 501a and 501b so that the both grip portions 501a and 501b of the seat clip 5 approach each other. That is, both grip portions 501a and 501b are interposed between the grip restricting portions 10 and 11 of the seat clip attachment assisting tool 1 in a state where both the sandwiching portions 500a and 500b of the seat clip 5 are separated. When the operator releases the grip on the grips 501a and 501b, the seat clip 5 is urged by the urging means so that the grips 501a and 501b are separated from each other. The movement is restricted by coming into contact with the grip restricting portions 10 and 11. Thereby, both the clamping parts 500a and 500b are maintained in the state which mutually separated (refer FIG.1 (b)).

  In this state, as shown in FIG. 5, either the seat clip attachment assisting tool 1 or the seat clip 5 is appropriately held (clamped) with the insulating Y-cots Y. That is, when operating the insulating Y-cots Y, the seat clip 5 is arranged so that the operator does not take an unreasonable posture and the workers and the insulating Y-cots Y do not approach or enter the environment in the live state. Is directly held by the insulating Yatco Y or indirectly via the seat clip attachment aid 1.

  Thereafter, the sheet is operated so that the insulating sheet S covered with the covering target T such as an overhead wire (wrapped around the covering target T) intervenes between the sandwiching portions 500a and 500b of the sheet clip 5 by operating the insulating Y-co. Place the clip 5. And the seat clip attachment auxiliary tool 1 is removed in this state. At this time, for example, the seat clip mounting assisting tool 1 is held by the insulating Y-cots Y, and the seat clip mounting assisting tool 1 is rotated using the connecting portion 12 side as a fulcrum while pressing the seat clip 5 against the insulating sheet S. Then, the pair of grip restricting portions 10 and 11 rotate and the seat clip 5 (grips 501a and 501b) comes out between them, and the seat clip mounting aid 1 can be removed from the seat clip 5.

  Moreover, the seat clip attachment auxiliary | assistance tool 1 can also be removed using the two insulating Yatco Y. That is, by holding the seat clip 5 so that the arrangement of the seat clip 5 is maintained by one insulating Y-cot Y, the seat clip 5 can be moved by moving the seat clip attaching auxiliary tool 1 by the other one insulating Y-tack Y. The seat clip attachment assisting tool 1 can be removed from.

  As described above, when the seat clip attachment assisting tool 1 is removed from the seat clip 5, the restriction of the grip portions 501a and 501b by the seat clip attachment assisting tool 1 (grip restricting portions 10 and 11) is released. As shown in FIG. 6, the urging means biases the two sandwiching portions 500 a and 500 b closer to each other to sandwich the insulating sheet S, and the insulating sheet S covering the covering target T is unintentionally removed. Can be prevented. In this state, the operator performs various operations on the periphery of the area covered with the insulating sheet S.

  When various operations are completed, the seat clip 5 is removed, and the insulating sheet S can be removed. At this time, as shown in FIG. 7, the insulating Y-cots Y are hooked and pulled on the wire 2 existing between the grip portions 501a and 501b of the seat clip 5. In this way, the force point at which the tensile force acts (the position where the insulating Y-cot Y is hooked) and the point of action where the tensile force acts (the ends of the grip portions 501a and 501b at which both ends of the wire 2 are hooked) are connected. Since the wire forms a triangle, a component of tension (tensile force) acting on the wire 2 acts in a direction in which the grip portions 501a and 501b are brought closer to each other. As a result, the grip portions 501a and 501b are brought close to each other (the holding portions 500a and 500b are separated from each other), and the holding of the insulating sheet S is released. Thereby, the seat clip 5 can be easily removed.

  As described above, according to the seat clip attachment assisting tool 1 having the above-described configuration, the pair of grip restricting portions 10 and 11 that face each other and the connecting portion 12 that connects the ends of the pair of grip restricting portions 10 and 11 to each other. The grip portions 501a and 501b that are close to each other between the pair of grip restricting portions 10 and 11 are configured to be able to intervene, and the grip portions 501a and 501b that intervene between the pair of grip restricting portions 10 and 11 are provided. Since the gripping portions 10a and 11b of the seat clip 5 are kept in contact with the grip regulating portions 10 and 11 that are opposed to each other by urging by the urging means, the grip regulating portions 10 and 11 are maintained. The grip portions 501a and 501b of the seat clip 5 intervening between 11 are in contact with the opposing grip regulating portions 10 and 11, Grip 501a to be spaced apart from each other at the urging of the energization means, will want to restrict the movement of 501b, sandwiching portion 500a of the sheet clip 5 can be maintained in a state of being separated 500b together. This eliminates the need to hold the grip portions 501a and 501b of the seat clip 5 with the insulating Y-shaped Y to separate the holding portions 500a and 500b of the seat clip 5, so that the seat clip 5 and the seat clip are attached with the insulating Y-shaped Y. An appropriate portion of at least one of the auxiliary tools 1 can be held by the insulating Y-cots Y.

  Therefore, when the insulating sheet S is interposed between the clamping portions 500a and 500b of the seat clip 5, the posture of the insulating jacket Y is not restrained by the posture of the seat clip 5, and the worker cannot perform the insulating jacket in an unreasonable posture. It is possible to prevent Y from being manipulated or from approaching or entering the environment in which the worker or the insulated Y-shaped Y is in a live state, and the safety of the worker can be sufficiently ensured.

Part 501a, 501b) (the opposing state between the grip parts 501a, 501b and the grip restricting parts 10, 11 is released) is the rotation amount of the grip restricting parts 10, 10 (the grip restricting parts 10, 10). The width in the direction perpendicular to the direction in which the 11 extends and the direction in which the pair of grip regulating portions 10 and 11 are arranged is smaller than the case where the width is constant. Thereby, the seat clip attachment auxiliary tool 1 according to the present embodiment can be smoothly removed from the seat clip 5 even if there is only one worker.

  It should be noted that the seat clip attachment assisting tool according to the present invention is not limited to the above-described embodiments, and it goes without saying that modifications can be made as appropriate without departing from the spirit of the present invention.

  In each of the above embodiments, the seat clip attachment assisting tool 1 is connected to the seat clip 5 via the wire 2. However, the present invention is not limited to this. For example, the seat clip attachment assisting tool 1 and the seat clip 5 are not limited thereto. And may be made independent of each other. Moreover, when connecting the seat clip attachment auxiliary | assistance tool 1 to the seat clip 5 via the wire 2, it is not limited to the aspect demonstrated by said each embodiment, For example, as shown in FIG. One end of the wire 2 may be connected to one grip portion 501b, and the other end of the wire 2 may be connected to the seat clip attachment assisting tool 1. And, in connecting the seat clip attachment assisting tool 1 to the seat clip 5 in the above-described manner, the minimum distance between the sandwiching bodies P, P when the sandwiching bodies P, P of the insulating Yachto Y are brought close to each other. When the wire 2 having a small wire diameter is employed, the seat clip attachment assisting tool 1 is preferably formed to have a size larger than the minimum distance between the sandwiching bodies P, P of the insulating jacket Y.

  In this way, when removing the sheet clip 5 sandwiching the insulating sheet S, the wire 2 cannot be directly sandwiched by the sandwiching bodies P, P of the insulating Y-cots Y. However, as shown in FIG. If the insulating Y-cog Y is pulled with the wire 2 interposed between the sandwiching bodies P, P, the seat clip attachment assisting tool 1 is caught on the sandwiching bodies P, P. As a result, the seat clip 5 is interposed via the wire 2. It will be pulled and removed from the insulating sheet 5. Since both the seat clip 5 and the seat clip attachment assisting tool 5 are larger in size than the minimum distance between the sandwiching bodies P, P of the insulating jacket Y, the seat clip 5 is detached from the insulating sheet S and suspended. However, it is also prevented that the sheet clip 5 or the seat clip attachment auxiliary tool 1 is caught by the sandwiching bodies P, P and the wire 2 is dropped from between the sandwiching bodies P, P.

  In each of the above-described embodiments, the wire 2 is connected to the holding protrusion 13. However, the present invention is not limited to this. For example, the wire 2 is connected to the grip restricting portions 10 and 11 or the connecting portion 12. In the case where the holding protrusions 14 project from the grip restricting portions 10 and 11, the wire 2 may be connected to the holding protrusions 14.

  In each of the above embodiments, the base end portions of the pair of grip regulating portions 10 and 11 are connected to each other via the connecting portion 12 and formed in a U shape in plan view. However, the present invention is not limited to this. The tip portions of the pair of grip restricting portions 10 and 11 may also be connected by another connecting portion 12, and may be formed in an annular shape, for example. That is, the pair of grip regulating portions 10 and 11 may be connected to each other at least one of the one end and the other end via the connecting portion 12. And a pair of grip control part 10,11 and the connection part 12 are not limited to what extended straight, You may curved in circular arc shape. Therefore, as described above, when the tip ends of the pair of grip restricting portions 10 and 11 are connected by another connecting portion 12, the seat clip attachment assisting tool 1 has the pair of grip restricting portions 10, 11 and the connecting portion 12 may be integrated so as to form an annular shape in plan view. If the pair of grip restricting portions 10 and 11 and the connecting portion 12 are integrally formed in an annular shape, the attachment / detachment with respect to the seat clip 1 is limited to only the direction orthogonal to the direction in which the grip restricting portions 10 and 11 extend. Considering the characteristics, it is preferable to connect only the base end portions of the pair of grip regulating portions 10 and 11 with the connecting portion 12 as in the above embodiment.

  In each of the above-described embodiments, the seat clip attachment auxiliary tool 1 attached to the seat clip 5 is removed by the insulating YAT Y. However, the present invention is not limited to this. For example, the seat clip 5 is arranged in the insulating sheet S. At the same time, the seat clip attachment assisting tool 1 may be removed from the seat clip 5.

  Specifically, as shown in FIG. 12, the rod-shaped sheet interference member 16 is attached to the connecting portion 12 so as to extend in a direction orthogonal to the extending direction of the grip restricting portions 10 and 11 and the extending direction of the connecting portion 12. You may make it project. If it does in this way, as shown in FIG. 13, in the state which interposed the grip parts 501a and 501b of the seat clip 5 between the grip control parts 10 and 11, it is a sheet | seat while interposing the insulating sheet S between the clamping parts 500a and 500b. When the front end of the interference member 16 is brought into contact with the insulating sheet S, the sheet interference member 16 is pushed in the axial direction, so that the seat clip attachment assisting tool 1 rotates with the connecting portion 12 side as a rotation fulcrum.

  Accordingly, the sheet clip attachment assisting tool 1 is removed from the sheet clip 5 with the insulating sheet S completely intervening between the clamping portions 500a and 500b, and at the same time, the sheet clip 5 sandwiches the insulating sheet S. Therefore, even one worker can make the sheet clip 5 correspond to the arrangement of the insulating sheet S and remove the sheet clip attachment auxiliary tool 1 from the sheet clip 5 (holding the insulating sheet S by the sheet clip 5). Can also be performed smoothly.

  Needless to say, as described in the third embodiment, if the grip regulating portions 10 and 11 are tapered, the amount of rotation necessary for rotating (twisting) and removing the seat clip attachment assisting tool 1. Therefore, when the sheet interference member 16 is provided as described above, it is preferable that the grip regulating portions 10 and 11 are tapered.

  In each of the above embodiments, the explanation has been made on the assumption that the insulating Y-cots Y are configured so that the tips of the sandwiching bodies P and P are in contact with each other. However, the present invention is not limited to this. For example, when sandwiching an object An insulating jacket (quick type insulating jacket) in which the tip portions of the pair of sandwiching bodies P, P intersect each other may be used. In this case, as shown in FIG. 14, it is preferable to form the holding projection piece 14 through the slit 14a. In this way, when the holding protrusion 14 is held by the insulating Y-shaped Y, the end portions of the holding bodies P, P can be inserted. The holding protrusion 14 can be held. In FIG. 14, the slits 14 a are formed in the holding protrusions 14 protruding from the grip restricting portions 10 and 11. However, the slits may be formed in the holding protrusions 13 protruding from the connecting portion 12. Of course.

  Further, when the slit 14a is formed in the holding projection piece 14, the edge E1 that defines the tip of the holding projection piece 14 is formed in an arc shape, and one end distance X is set from the edge E1 along the edge E1. It is preferable to form the arc-shaped slit 14a in the opened position. In this way, the distance X between the tip (edge) E1 of the holding protrusion 14 and the edge E2 defining the slit 14a is constant in the circumferential direction, and is held at an appropriate position in the extending direction of the slit 14a. The projecting piece 14 can be held between the insulating Y-cots Y.

  In each of the above embodiments, the length in the axial direction of the pair of grip restricting portions 10 and 11 is set to be the same or substantially the same, but is not limited to this. For example, one grip restricting portion 10 is connected to the other. You may form longer than the grip control part 11. If it does in this way, both grip parts 501a and 501b can be made to intervene between a pair of grip control parts 10 and 11 along with one grip part 501a and 501b along the other grip control part 11 formed long. .
