Description

本発明は、間接活線工法において、架空配電線等の電線の存在を喚起するための電線管（例えば、ジャバラポリ管）を電線に挿入・取り付け又電線から電線管を撤去する際に用いられる電線管挿入用工具及びこの工具を用いた電線管挿入工法に関し、特に、電線を防護するための電線防護管を電線に取り付ける際に用いられる電線管挿入用工具及び電線管挿入工法に関するものである。   The present invention relates to an indirect hot wire construction method in which an electric wire tube (for example, bellows poly tube) for arousing the presence of an electric wire such as an aerial distribution wire is inserted / attached to / from an electric wire and the electric wire used when the electric wire tube is removed from the electric wire. The present invention relates to a tube insertion tool and a conduit insertion method using the tool, and more particularly to a conduit insertion tool and a conduit insertion method used when a wire protection tube for protecting a wire is attached to the wire.

一般に、直接活線工法において、架空配電線（以下単に電線と呼ぶ）にジャバラポリ管等の電線管（例えば、電線を防護するための電線防護管）を取り付ける場合、図１０〜図１２に示す工法が用いられる。ジャバラポリ管に電線を挿入する際には、後述する挿入管及びガイドクリップが用いられ、まず、図１０に示すように、ジャバラポリ管１１の開口端に挿入管１２が挿入される。   In general, in the direct hot wire method, when a conduit such as a bellows poly pipe (for example, a wire protective tube for protecting the wire) is attached to an overhead distribution line (hereinafter simply referred to as an electric wire), the method shown in FIGS. Is used. When inserting an electric wire into the bellows poly pipe, an insertion pipe and a guide clip which will be described later are used. First, as shown in FIG. 10, the insertion pipe 12 is inserted into the open end of the bellows poly pipe 11.

ジャバラポリ管１１はその周面が蛇腹形状となっており、その長手方向に沿って切り込み部１１ａが形成され、この切り込み部１１ａから電線（図１０には示さず）がジャバラポリ管１１に挿入される。上述の切り込み部１１ａは、ジャバラポリ管の電線からの脱落を防止するため、通常は閉じた状態にあり、ジャバラポリ管１１に電線を挿入するに当たっては、ジャバラポリ管１１の内径よりもその外径が大きい挿入管１２をジャバラポリ管１１の開口端から挿入して、ジャバラポリ管を押し広げて、前述の切り込み部１１ａを開く必要がある。   The bellows poly pipe 11 has a bellows-shaped peripheral surface, and a cut portion 11a is formed along the longitudinal direction. An electric wire (not shown in FIG. 10) is inserted into the bellows poly pipe 11 from the cut portion 11a. . The above-described cut portion 11a is normally closed to prevent the bellows-poly tube from falling off from the electric wire. When the electric wire is inserted into the bellows-poly tube 11, the outer diameter thereof is larger than the inner diameter of the bellows-poly tube 11. It is necessary to insert the insertion pipe 12 from the opening end of the bellows poly pipe 11 and push the bellows poly pipe to open the above-described cut portion 11a.

続いて、電線（例えば、縁線）１３にガイドクリップ１４を取り付けた後（図１１参照）、図１２に示すように、ガイドクリップ１４で電線１３を案内しつつ、図中右側から切り込み部１１ａを介して電線１３をジャバラポリ管１１に挿入して、電線１３にジャバラポリ管１１を取り付ける。   Subsequently, after attaching the guide clip 14 to the electric wire (for example, the edge line) 13 (see FIG. 11), as shown in FIG. 12, while guiding the electric wire 13 with the guide clip 14, the cut portion 11a from the right side in the figure. Then, the electric wire 13 is inserted into the bellows poly pipe 11 and the bellows poly pipe 11 is attached to the electric wire 13.

一方、間接活線工法において、電線にジャバラポリ管を取り付ける際には、例えば、ヤットコ等所要の間接活線把持工具によってジャバラポリ管の切り込み部を開いて電線にジャバラポリ管を取り付けるようにしている（例えば、特許文献１参照）。
特開２００４−３２０９６１号公報 On the other hand, when the bellows poly pipe is attached to the electric wire in the indirect hot wire method, the bellows poly pipe is attached to the electric wire by opening the cut portion of the bellows poly pipe with a required indirect hot wire gripping tool such as a yatco (for example, , See Patent Document 1).
JP 2004-320961 A

ところで、間接活線工法によって、電線にジャバラポリ管を取り付ける際には、ヤットコを用いてジャバラポリ管の切り込み部を開いて、この切り込み部から電線をジャバラポリ管に挿入しているものの、一般にヤットコはその把持部（レバー）を握ると先端側（作用部側）が閉じる構成であるため、ジャバラポリ管の切り込み部を開くためには、ヤットコの把持部を開く方向に力を加えて、ヤットコの作用部側（つまり、先端側）を開く必要がある。   By the way, when attaching a bellows poly pipe to an electric wire by the indirect hot wire method, a notched part of the bellows poly pipe is opened using a yatco, and the electric wire is inserted into the bellows poly pipe from this notch. Since the tip side (acting part side) closes when the gripping part (lever) is gripped, in order to open the notch part of the bellows poly pipe, force is applied in the direction of opening the gripping part of the yatco, and the acting part of the yatco The side (ie, the tip side) needs to be opened.

しかしながら、間接活線工法において、電柱等に登って通電状態にある電線にジャバラポリ管を取り付けるとなると、ヤットコの把持部（レバー）を開いて、ヤットコの先端部を開方向に動作させる。そして、ジャバラポリ管の切り込み部を開きつつ、この切り込み部から電線をジャバラポリ管に挿入するとなると、作業が極めて行いづらく、その結果、作業員が感電する等の事故が発生するという危険性が増大するという課題がある。   However, in the indirect hot wire method, when a bellows poly pipe is attached to a wire that is energized by climbing on a utility pole or the like, the gripping portion (lever) of the yatco is opened and the tip of the yatco is moved in the opening direction. And, when the cut portion of the bellows poly pipe is opened and the electric wire is inserted into the bellows poly pipe from the cut portion, the work is extremely difficult to perform, and as a result, the risk of an accident such as an electric shock of the worker increases. There is a problem.

従って、本発明の目的は、間接活線工法において容易に電線にジャバラポリ管等の電線管を取り付けることのできる電線管挿入用工具及びこの工具を用いた電線管挿入工法を提供することにある。   Accordingly, an object of the present invention is to provide a conduit insertion tool that can easily attach a conduit such as a bellows poly tube to an electric wire in an indirect hot wire method, and a conduit insertion method using this tool.

And a connecting member for connecting the first and second action members.

本発明の電線管挿入用工具は、前記第１及び前記第２の操作部材の後端にヤットコの先端部を装着するための装着アダプターが設けられている。   The conduit tube insertion tool of the present invention is provided with a mounting adapter for mounting the tip of the Yatco to the rear ends of the first and second operating members.

本発明では、前記電線管は、例えば、ジャバラ管であり、前記第１及び前記第２の作用部材の先端部には径方向外側に突起する突起部がそれぞれ形成されている。   In the present invention, the electric wire tube is, for example, a bellows tube, and a protruding portion protruding outward in the radial direction is formed at a tip portion of each of the first and second action members.

本発明では、前記電線管を前記電線に挿入・取り付ける際、前記電線管の開口端から前記第１及び前記第２の作用部材の先端部が挿入され、前記第１及び前記第２の操作部材が閉じる方向に操作されると、前記第１及び前記第２の操作部材が前記所定の方向に平行な回転軸回りに開く方向に動作して前記切り込み部を開く。   In the present invention, when the conduit tube is inserted and attached to the wire, the distal ends of the first and second action members are inserted from the open ends of the conduit tube, and the first and second operation members are inserted. Is operated in a closing direction, the first and second operating members operate in a direction of opening around a rotation axis parallel to the predetermined direction to open the cut portion.

本発明による電線管挿入工法は、間接活線工法において上述の電線管挿入用工具を用いて電線に電線管を挿入・取り付ける際に用いられ、前記電線管は絶縁弾性材料で成形されて、その長手方向に沿って切り込み部が形成されており、前記電線管の開口端から前記第１及び前記第２の作用部材の先端部を挿入する第１のステップと、前記第１及び前記第２の操作部材を閉じる方向に操作して前記第１及び前記第２の操作部材を開く方向に動作させ、前記切り込み部を開く第２のステップと、前記切り込み部から前記電線に前記電線管を挿入する第３のステップとを有することを特徴とするものである。   The conduit insertion method according to the present invention is used when inserting and attaching a conduit to an electric wire using the above-described conduit insertion tool in the indirect hot wire method, and the conduit is formed of an insulating elastic material. A notch is formed along the longitudinal direction, and a first step of inserting the distal ends of the first and second action members from the open end of the conduit, and the first and second A second step of opening the cut portion by operating the operation member in a closing direction to open the first and second operation members, and inserting the conduit from the cut portion into the electric wire. And a third step.

以上のように、本発明によれば、第１及び第２の操作部材に第１及び第２の作用部材の一端部を所定の方向に延びる回転軸回りに回動可能にそれぞれ取り付け、第１及び第２の作用部材においてその一端部と他端部との間で所定の方向と平行な回転軸回りに回動可能に第１及び第２の作用部材を連結するようにしたので、第１及び第２の操作部材が握られる等によって閉じる方向に操作されると、第１及び第２の作用部は上記の回転軸回りに開く方向に回動することになって、第１及び第２の作用部材の先端部を電線管の開口端から挿入しておけば、電線管に開く方向に力が作用することになって、切り込み部を容易に開くことができる。その結果、間接活線工法において容易に電線に電線管を取り付けることができるという効果がある。   As described above, according to the present invention, the first and second operation members are attached to the first and second operation members in such a manner that the one end portions of the first and second action members can rotate about the rotation axis extending in a predetermined direction. In the second action member, the first and second action members are connected between the one end and the other end so as to be rotatable around a rotation axis parallel to a predetermined direction. When the second operation member is operated in the closing direction, for example, by being gripped, the first and second action portions are rotated in the opening direction around the rotation axis, and the first and second operations are performed. If the tip of the working member is inserted from the opening end of the conduit, a force acts in the opening direction on the conduit, and the notch can be easily opened. As a result, there is an effect that the conduit can be easily attached to the electric wire in the indirect hot wire method.

Since the protrusion is caught by the bellows, there is an effect that the cut portion of the conduit can be easily opened.

以下、本発明の実施形態による電線管挿入用工具の一例について図面を参照して説明する。なお、この電線管挿入用工具は、間接活線工法において、電線の存在を喚起するための電線管を電線に挿入・取り付ける際に用いられるものであるが、ここでは一例として、電線の存在を喚起するとともに、電線を防護する電線防護管を電線に挿入・取り付ける場合について説明する。   Hereinafter, an example of a conduit tube insertion tool according to an embodiment of the present invention will be described with reference to the drawings. This conduit insertion tool is used when inserting / attaching a conduit for inducing the presence of an electrical wire in an indirect hot wire method. We will explain how to insert and attach a wire protection tube that protects the wire to the wire.

まず図１を参照すると、図示の電線管挿入用工具（以下単に工具と呼ぶ）２０は、例えば、ヤットコ（図１には示さず）の先端部に取り付けられる。図１（ａ）は工具２０を側方から見た図、図１（ｂ）は工具２０を上方から見た図、図１（ｃ）は工具２０を後方から見た図である。   Referring first to FIG. 1, a conduit insertion tool 20 (hereinafter simply referred to as a tool) 20 is attached to, for example, the tip of a Yatco (not shown in FIG. 1). 1A is a view of the tool 20 viewed from the side, FIG. 1B is a view of the tool 20 viewed from above, and FIG. 1C is a view of the tool 20 viewed from the rear.

図１（ａ）〜（ｃ）に示すように、工具２０は第１及び第２の操作部（操作部材）２１及び２２を有しており、後述するように、第１及び第２の操作部２１及び２２にはヤットコの先端部がそれぞれ取り付けられる。これら第１及び第２の操作部２１及び２２の先端部にはそれぞれ第１及び第２の回動部２３及び２４を介して第１及び第２の作用部（作用部材）２５及び２６が連結され、第１及び第２の作用部２５及び２６はそれぞれ第１及び第２の回動部２３及び２４回り（所定の方向回り：図１（ａ）において紙面の表側から裏側に延びる方向回り）に回動可能となっている。   As shown in FIGS. 1A to 1C, the tool 20 has first and second operation portions (operation members) 21 and 22, and the first and second operations are described later. At the portions 21 and 22, the end portions of Yatco are respectively attached. First and second action parts (action members) 25 and 26 are connected to the distal ends of the first and second operation parts 21 and 22 via first and second rotating parts 23 and 24, respectively. The first and second action parts 25 and 26 are respectively around the first and second rotating parts 23 and 24 (around a predetermined direction: around a direction extending from the front side to the back side of the paper surface in FIG. 1A). Can be rotated.

図示のように、第１及び第２の作用部２５及び２６には、その後端と先端との間においてそれぞれ第１及び第２の連結部２５ａ及び２６ａが形成され、第１及び第２の連結部２５ａ及び２６ａはピン部材（連結部材）２７で連結され、第１及び第２の作用部２５及び２６はピン部材２７回り（所定の方向に平行な方向回り）に回動可能となっている。そして、第１及び第２の作用部２５及び２６の先端部にはそれぞれ第１及び第２の突起部２５ｂ及び２６ｂが形成され、これら第１及び第２の突起部２５ｂ及び２６ｂは径方向外側に突出している。   As shown in the figure, the first and second action portions 25 and 26 are respectively formed with first and second connection portions 25a and 26a between the rear end and the front end, respectively. The parts 25a and 26a are connected by a pin member (connecting member) 27, and the first and second action parts 25 and 26 are rotatable around the pin member 27 (around a direction parallel to a predetermined direction). . And the 1st and 2nd protrusion parts 25b and 26b are formed in the front-end | tip part of the 1st and 2nd action parts 25 and 26, respectively, and these 1st and 2nd protrusion parts 25b and 26b are radial direction outer sides. Protruding.

図２も参照すると、図２は上述の工具２０にヤットコ３０を取り付けた状態を示す図であり、ヤットコ３０の先端部がそれぞれ第１及び第２の操作部２１及び２２に取り付けられる（取り付け方法については後述する）。ヤットコ３０は周知のように、後端側の把持レバーを握ると先端側が閉じ、把持レバーを放すとその先端側が開くものである。   Referring also to FIG. 2, FIG. 2 is a view showing a state where the tool 30 is attached to the above-described tool 20, and the front end portion of the tool 30 is attached to the first and second operation parts 21 and 22 (attachment method) Will be described later). As is well known, the YATCO 30 closes the tip when the grip lever on the rear end side is gripped, and opens the tip when the grip lever is released.

ここで再び図１（ａ）を参照すると、いまヤットコの把持レバーを握ると、ヤットコの先端部が閉じる。ヤットコの先端部が閉じると、第１及び第２の操作部２１及び２２も閉じる方向に動くが、第１及び第２の作用部２５及び２６はピン部材２７によって連結され、ピン部材２７回りに回動可能であるから、第１及び第２の作用部２５及び２６の後端側がそれぞれ第１及び第２の回動部２３及び２４回りに回動して閉じる方向に動作すると、第１及び第２の作用部２５及び２６の先端側はピン部材２７回りに開く方向に回動し、この結果、第１及び第２の作用部２５及び２６は開く方向に動くことになる。つまり、ヤットコの把持レバーを握ると、工具２０の先端部は図１（ａ）に示すように開くことになる。   Here, referring to FIG. 1A again, if the grip lever of the lever is now gripped, the tip of the lever closes. When the tip of the Yatco is closed, the first and second operation parts 21 and 22 are also moved in the closing direction, but the first and second action parts 25 and 26 are connected by a pin member 27 and around the pin member 27. Since the rear end sides of the first and second action portions 25 and 26 are rotated around the first and second rotation portions 23 and 24 and moved in the closing direction, respectively, The distal end sides of the second action parts 25 and 26 rotate in the opening direction around the pin member 27. As a result, the first and second action parts 25 and 26 move in the opening direction. That is, when the grip lever of Yatco is gripped, the tip of the tool 20 opens as shown in FIG.

続いて、図２及び図３を参照すると、図２は工具２０を閉じた状態で示す図であり、図３は工具２０を開いた状態で示す図である。ジャバラポリ管１１の切り込み部１１ａを開く際には、ヤットコ３０の把持レバーを握らない状態で、つまり、工具２０を閉じた状態で、ジャバラポリ管１１の開口端からジャバラポリ管１１に工具２０の先端部を挿入する（図２参照）。   2 and 3, FIG. 2 is a view showing the tool 20 in a closed state, and FIG. 3 is a view showing the tool 20 in an opened state. When opening the notch 11a of the bellows poly pipe 11, the tip end of the tool 20 from the opening end of the bellows poly pipe 11 to the bellows poly pipe 11 without gripping the grip lever of the yatco 30, that is, with the tool 20 closed. Is inserted (see FIG. 2).

続いて、ヤットコ３０の把持レバーを握ると、前述したように、工具２０が開く。工具２０の先端部には径方向外側に突出する突起部２５ｂ及び２６ｂが設けられているから、これら突起部２５ｂ及び２６ｂがジャバラポリ管１１の蛇腹に引っかかり、工具２０が開くにつれて、つまり、ヤットコ３０の把持レバーを握るにつれて、図３に示すように、ジャバラポリ管１１の切り込み部１１ａが開かれることになり、このようにして開かれた切り込み部１１ａから電線（図示せず）を挿入するようにすればよい（つまり、間接活線工法においてジャバラポリ管１１を電線に取り付けるようにすればよい）。   Subsequently, when the grip lever of the Yatco 30 is gripped, the tool 20 is opened as described above. Since the projecting portions 25b and 26b projecting radially outward are provided at the distal end portion of the tool 20, the projecting portions 25b and 26b are caught by the bellows of the bellows poly pipe 11 and the tool 20 is opened, that is, the YATCO 30. As shown in FIG. 3, the notch 11a of the bellows poly pipe 11 is opened, and an electric wire (not shown) is inserted from the notch 11a thus opened. What is necessary is just to attach the bellows poly pipe 11 to an electric wire in an indirect hot wire construction method.

ここで、間接活線工法におけるジャバラポリ管の取り付けについて説明する。図４及び図５を参照すると、図４は電柱を側方から見た図、図５は電柱を正面から見た図である。電柱３１はその高さが約１２メートルであり、その頂部付近には高圧引下線引留金物３２が取り付けられており、その下側には電線支持具（４線用）３３が取り付けられている。   Here, attachment of the bellows poly pipe in the indirect hot wire method will be described. Referring to FIGS. 4 and 5, FIG. 4 is a diagram of the utility pole viewed from the side, and FIG. 5 is a diagram of the utility pole viewed from the front. The utility pole 31 has a height of about 12 meters, a high voltage underline retainer 32 is attached to the vicinity of the top thereof, and an electric wire support (for 4-wire) 33 is attached to the lower side.

さらに、電柱３１には、低圧引上線３４及び高圧引下線３５が配設され、高圧カットアウト支持アーム３６には変圧器３７が配置されて、この変圧器３７は変圧器取付バンド３７ａによって電柱３１に固定されている。そして、高圧引下線３５は高圧カットアウト３８を介して変圧器３７に引き込まれ、変圧器３７から低圧引上線３４が引き上げられて、引込み線３９に連結される。なお、変圧器３７の下側には、引込専用腕金４０が配設され、電柱３１には、高圧カットアウト操作用足場４１が設けられている。   Further, the utility pole 31 is provided with a low-voltage pull-up line 34 and a high-voltage under-line 35, and a high-voltage cutout support arm 36 is provided with a transformer 37. The transformer 37 is connected to the power pole 31 by a transformer mounting band 37a. It is fixed to. Then, the high voltage underline 35 is drawn into the transformer 37 via the high voltage cutout 38, and the low voltage upline 34 is pulled up from the transformer 37 and connected to the lead line 39. A pull-in armature 40 is disposed below the transformer 37, and a high voltage cutout operation scaffold 41 is provided on the utility pole 31.

間接活線工法によって、電線、例えば、高圧引下線３５及び引込み線３９にジャバラポリ管１１を取り付ける際には、図１１〜図１３を用いて説明した直接活線工法における挿入管及びガイドクリップを用いることはできない。このため、ここでは、前述した工具２０を用いてジャバラポリ管１１の切り込み部１１ａを開いて、この切り込み部１１ａから電線をジャバラポリ管１１に挿入する。   When the bellows poly pipe 11 is attached to the electric wire, for example, the high-voltage underline 35 and the lead-in line 39 by the indirect hot wire method, the insertion tube and the guide clip in the direct hot wire method described with reference to FIGS. It is not possible. For this reason, here, the notch part 11a of the bellows poly pipe 11 is opened using the tool 20 described above, and the electric wire is inserted into the bellows poly pipe 11 from the notch part 11a.

まず、工具２０をヤットコ３０に取り付ける（取り付け方法について後述する）。そして、ヤットコ３０の把持レバーを把持しない状態（つまり、握らない状態）で、工具２０の先端側（つまり、第１及び第２の作用部２５及び２６）をジャバラポリ管１１の開口端からジャバラポリ管１１に挿入する。続いて、ヤットコ３０の把持レバーを握ると、ヤットコ３０の先端部は閉じ、これによって、第１及び第２の作用部２５及び２６が開く方向に動作する。   First, the tool 20 is attached to the Yatco 30 (an attachment method will be described later). The tip end side (that is, the first and second action portions 25 and 26) of the tool 20 is moved from the opening end of the bellows poly pipe 11 to the bellows poly pipe in a state in which the grip lever of the yatco 30 is not gripped (that is, not gripped). 11 is inserted. Subsequently, when the grip lever of the yatco 30 is gripped, the tip of the yatco 30 is closed, and thereby the first and second action portions 25 and 26 are operated in the opening direction.

第１及び第２の作用部２５及び２６が開くにつれて、第１及び第２の突起部２５ｂ及び２６ｂがジャバラポリ管１１の蛇腹に引っかかって、ジャバラポリ管１１に開く方向の力が作用する。そして、第１及び第２の作用部２５及び２６がさらに開かれると、切り込み部１１ａが開く。切り込み部１１ａを開いた状態とした後、切り込み部１１ａから電線を挿入し、ジャバラポリ管１１を電線に取り付ける。   As the first and second action portions 25 and 26 open, the first and second protrusions 25b and 26b are caught by the bellows of the bellows poly pipe 11, and a force in the opening direction acts on the bellows poly pipe 11. And if the 1st and 2nd action parts 25 and 26 are opened further, the notch part 11a will open. After the cut portion 11a is opened, an electric wire is inserted from the cut portion 11a, and the bellows poly pipe 11 is attached to the electric wire.

このようにして、工具２０を用いることによって、ヤットコ３０の把持レバーを把持すれば、工具２０によってジャバラポリ管１１の切り込み部１１ａを容易に開くことができ、この切り込み部１１ａから電線を挿入するようにすればよく、間接活線工法においても簡単に電線にジャバラポリ管１１を取り付けることができる。   Thus, by using the tool 20, if the grip lever of the Yatco 30 is gripped, the cut portion 11a of the bellows poly pipe 11 can be easily opened by the tool 20, and an electric wire is inserted from the cut portion 11a. The bellows poly pipe 11 can be easily attached to the electric wire even in the indirect hot wire method.

続いて、工具２０をヤットコ３０に取り付ける際に用いられる取付アダプターについて説明する。なお、以下の説明では、取付アダプターを用いて工具２０の代わりにラジオペンチをヤットコに取り付ける例について説明するが、工具２０についても同様にして取付アダプターを用いてヤットコに取り付けることができる。   Then, the attachment adapter used when attaching the tool 20 to the Yatco 30 is demonstrated. In addition, although the following description demonstrates the example which attaches a radio pliers to a yatco instead of the tool 20 using an attachment adapter, the tool 20 can be similarly attached to a yatco using an attachment adapter.

図６を参照すると、図６は取付アダプターを示す斜視図であり、取付アダプター５０は筐体部５１を有しており、この筐体部５１の底外面にはラジオペンチを構成するラジオペンチ部５２が固定されている。   Referring to FIG. 6, FIG. 6 is a perspective view showing the mounting adapter, and the mounting adapter 50 has a casing 51, and a radio pliers that constitutes a radio pliers on the bottom outer surface of the casing 51. 52 is fixed.

筐体部５１の一面（側面）は開放されて、筐体部５１内には挿入空間５３が規定されている。また、筐体部５１の上面には図中上方に延びるシリンダー部５４が形成され、このシリンダー部５４の内周面にはネジが切られている。そして、このシリンダー部５４にはボルト体５５が螺合され、ボルト体５５を回転すると、ボルト体５５はシリンダー部５４に沿って上下方向に移動する。   One surface (side surface) of the housing part 51 is open, and an insertion space 53 is defined in the housing part 51. A cylinder portion 54 extending upward in the figure is formed on the upper surface of the housing portion 51, and a screw is cut on the inner peripheral surface of the cylinder portion 54. A bolt body 55 is screwed onto the cylinder portion 54, and when the bolt body 55 is rotated, the bolt body 55 moves in the vertical direction along the cylinder portion 54.

続いて、図７及び図８を参照すると、図７及び図８はそれぞれ取付アダプターを開口端側から見た図であり、図７に示す状態においては、ボルト体５５は上方に移動されており、一方、図８に示す状態では、ボルト体５５は下方に移動されて、その先端部５５ａが挿入空間５３に突出している。   Next, referring to FIG. 7 and FIG. 8, FIG. 7 and FIG. 8 are views of the mounting adapter viewed from the opening end side, respectively, and in the state shown in FIG. 7, the bolt body 55 is moved upward. On the other hand, in the state shown in FIG. 8, the bolt body 55 is moved downward, and its distal end portion 55 a protrudes into the insertion space 53.

取付アダプター５０にヤットコを取り付ける際には、図７に示す状態において、取付アダプター５０の開口端から挿入空間５３にヤットコの先端部を挿入する。そして、ヤットコの先端部を挿入空間５３に挿入した後、例えば、手動でボルト体５５を回転させて、図８に示す状態とする。つまり、ボルト体５５の先端部５５ａが挿入空間５３に突出した状態とする。   When attaching the yatco to the mounting adapter 50, the tip of the yatko is inserted into the insertion space 53 from the opening end of the mounting adapter 50 in the state shown in FIG. And after inserting the front-end | tip part of a Yatsuko into the insertion space 53, the bolt body 55 is rotated manually, for example, and it is set as the state shown in FIG. That is, the tip end portion 55 a of the bolt body 55 is projected into the insertion space 53.

図８に示す状態にすると、ヤットコの先端部はボルト体５５の先端部５５ａと筐体部５１の内底面との間で挟持されることになって、挿入空間５３からヤットコの先端部が抜けることがなくなる。   In the state shown in FIG. 8, the tip end portion of the yatco is sandwiched between the tip end portion 55 a of the bolt body 55 and the inner bottom surface of the housing portion 51, and the tip end portion of the yatco comes out of the insertion space 53. Nothing will happen.

ラジオペンチとして用いる際には、別の取付アダプターにヤットコの他方の先端部を取り付けることになる。つまり、図９に示すように、一対の取付アダプター５０をそれぞれヤットコ３０の先端部に前述したようにして取り付けるようにすればよい。   When using it as a radio pliers, the other tip of the Yatco is attached to another attachment adapter. That is, as shown in FIG. 9, the pair of attachment adapters 50 may be attached to the tip of the Yatco 30 as described above.

なお、一対の取付アダプター５０にはそれぞれラジオペンチ部５２ａ及び５２ｂが取り付けられており、これらラジオペンチ部５２ａ及び５２ｂによってラジオペンチが構成される。そして、ヤットコ３０を開けばラジオペンチも開き、ヤットコ３０を閉じればラジオペンチも閉じる。   Radio pliers 52a and 52b are attached to the pair of attachment adapters 50, respectively, and the radio pliers 52a and 52b constitute radio pliers. Then, opening the yatco 30 opens the radio pliers, and closing the yatco 30 closes the radio pliers.

上述の説明から明らかなように、図１で説明した工具２０の第１及び第２の操作部２１及び２２の後端にそれぞれ前述の取付アダプター５０を備えるようにすれば、これら取付アダプター５０にヤットコ３０の先端部を挿入して、前述したようにして、ヤットコ３０の先端部と取付アダプター５０とを連結すると、ヤットコ３０と工具２０とを簡単に接続することができる。そして、ヤットコ３０を開けば工具２０が閉じ、ヤットコ３０を閉じれば工具２０が開くことになる。   As is apparent from the above description, if the above-described mounting adapters 50 are provided at the rear ends of the first and second operating portions 21 and 22 of the tool 20 described in FIG. When the tip of the Yachco 30 is inserted and the tip of the Yatco 30 and the mounting adapter 50 are coupled as described above, the Yatco 30 and the tool 20 can be easily connected. Then, the tool 20 is closed when the yatco 30 is opened, and the tool 20 is opened when the yatco 30 is closed.
