In other words, the sleeve support 21 is arranged between the first core support 26a and the second core support 26b.

In the example described in FIG. 1, although the sleeve support 21 and the core wire support 26 are independent entities, the sleeve support 21 and the core wire support 26 may also be integrated. In other words, at least a part of the sleeve support 21 and at least a part of the core wire support 26 may be shared.

Furthermore, when a remote operation tool is used to maintain the integrated state of the central axis of the exposed core wire WC and the central axis of the sleeve SV, or when the sleeve support 21 also has the function of the core support, etc. The core wire support 26 is omitted.

The first sliding rod 4 is arranged on one side of the base 2 (the first direction side in the example described in FIG. 1 ), and is a member that can slide and move relative to the base 2. By operating the slide bar operating portion 6, the amount of protrusion of the first slide bar 4 from the first direction side end 20a of the base portion 2 can be changed. In the example described in FIG. 1, when the sliding bar operating portion 6 (more specifically, the first sliding bar operating portion 6a) is operated in the first operating direction R1, the first sliding bar 4 is pulled toward the base 2 side . As a result, the amount of protrusion of the first sliding rod 4 from the first direction side end 20a is reduced. On the other hand, when the sliding rod operation part 6 (more specifically, the first sliding rod operation part 6a) is operated in the second operation direction, the first sliding rod 4 moves in a direction protruding from the base 2 side. As a result, the amount of protrusion of the first sliding rod 4 from the first direction side end 20a increases.

By operating the slide bar operating portion 6, the amount of protrusion of the second slide bar 5 from the second direction side end 20b of the base portion 2 can be changed. In the example described in FIG. 1, when the sliding bar operating portion 6 (more specifically, the second sliding bar operating portion 6b) is operated in the first operating direction R3, the second sliding bar 5 is pulled toward the base 2 side . As a result, the amount of protrusion of the second sliding rod 5 from the second direction side end 20b is reduced. On the other hand, when the sliding rod operation part 6 (more specifically, the second sliding rod operation part 6b) is operated in the second operation direction R4, the second sliding rod 5 moves in a direction protruding from the base 2 side. As a result, the amount of protrusion of the second sliding rod 5 from the second direction side end 20b increases.

The sliding rod operation part 6 is an operation part that can slide the first sliding rod 4 and the second sliding rod 5. In the example described in FIG. 1, the sliding bar operating portion 6 is provided with: a first sliding bar operating portion 6a for sliding movement of the first sliding bar 4; and a second sliding bar operating portion 6b for sliding the second sliding bar 5 mobile. In addition, the sliding movement of the first sliding bar 4 and the sliding movement of the second sliding bar 5 can be operated independently. More specifically, when the first sliding bar operating portion 6 a is operated, the first sliding bar 4 moves relative to the base 2, but the second sliding bar 5 does not move relative to the base 2. In addition, when the second sliding bar operation portion 6b is operated, the second sliding bar 5 relatively moves with respect to the base 2, but the first sliding bar 4 does not relatively move with respect to the base 2.

In addition, when the sleeve mounting tool 1A has a mechanism for selectively transmitting the operating force acting on the sliding rod operating portion 6 to either the first sliding rod 4 or the second sliding rod 5, etc., it may be The first sliding bar operating portion 6a and the second sliding bar operating portion 6b are shared.

The first electric wire gripping tool 7a grips the first electric wire W1 (more specifically, the part WP1 of the first electric wire W1 where the core wire is not exposed). The first electric wire holding tool 7a is connected to the end of the first sliding rod 4. According to this, when the first sliding rod 4 slidably moves with respect to the base 2, the first electric wire gripping tool 7 a relatively moves with respect to the base 2. In the example shown in FIG. 1, the sleeve installation tool 1A is equipped with the 1st electric wire holding tool 7a. As an alternative, in the shipping state, etc., the sleeve installation tool 1A may not have the first electric wire holding tool 7a, and the sleeve installation tool 1A is configured to be mounted on the existing first electric wire holding tool. .

The second wire gripping tool 7b grips the second wire W2 (more specifically, the portion WP2 of the second wire W2 where the core wire is not exposed). The second electric wire gripping tool 7b is connected to the end of the second sliding rod 5. According to this, when the second sliding rod 5 is slidably moved with respect to the base 2, the second electric wire gripping tool 7 b relatively moves with respect to the base 2. In the example shown in FIG. 1, the sleeve installation tool 1A is equipped with the 2nd electric wire holding tool 7b. As an alternative, in the shipping state, etc., the sleeve installation tool 1A may not have the second wire holding tool 7b, and the sleeve installation tool 1A is configured to be mounted on an existing second wire holding tool. .

In the sleeve installation tool 1A of the first embodiment, the sliding rod operating portion 6 can independently operate the sliding movement of the first sliding rod 4 and the sliding movement of the second sliding rod 5. Accordingly, when inserting the exposed core wire WC1 of the first electric wire W1 into the sleeve SV, it is only necessary to move the first sliding rod 4 by a distance shorter than the length of the sleeve SV (refer to Fig. 1(a) and Fig. 1() b)). When inserting the exposed core wire WC2 of the second electric wire W2 into the sleeve SV, it is sufficient to move the second sliding rod 5 a distance shorter than the length of the sleeve SV (refer to Figure 1(c) and Figure 1 (d)). Therefore, in the step of connecting the first electric wire W1 and the second electric wire W2 through the sleeve SV, the distance between the first electric wire holding tool 7a and the second electric wire holding tool 7b can be suppressed more than in the past. enlarge. As a result, it is possible to suppress slack in the entirety of the first electric wire W1 and the second electric wire W2.

In addition, the base portion 2 of the sleeve mounting tool 1A of the first embodiment may be divided or bendable at a substantially central portion. In the case of being divisible, for example, a concave portion is provided on one side of the divided body of the base 2 and a convex portion is provided on the other side of the divided body, and the concave portion and the convex portion are engaged with each other and then fixed with screws or the like. Alternatively, the shape of the split body may be such that the split bodies will not be separated from each other when force is applied in the first direction and the second direction, and the split body on one side may be placed in the first direction and the split body on the other side. Move in the vertical direction of the second direction, thereby joining and/or separating the two divided bodies. Moreover, when making it bendable, it is only necessary to connect it with a hinge etc. so that the base part 2 can bend at substantially the center part. The sleeve installation tool 1A can be folded into two sections because it is divided or bent on the approximate center of the base 2, so that the sleeve installation tool 1A can be made compact during transportation or storage.化.

In addition, the end of the exposed core wire WC tends to expand radially outward. In the past, it was not easy to insert the exposed core wire WC into a sleeve opening that is slightly larger than the inner diameter of the exposed core wire WC. In contrast to this, in the first embodiment, when the sleeve installation tool 1A is provided with the core wire support 26, the core wire WC can be exposed more easily in the step of inserting the exposed core wire WC into the sleeve SV. Align with the sleeve SV. Therefore, the work of inserting the exposed core wire WC into the opening of the sleeve becomes easier. More specifically, when the sleeve SV is supported by the sleeve support 21 and the core wire WC is supported by the core support 26, only the sliding rod (the first sliding rod 4 or the second sliding The rod 5) is pulled to the base 2 side to automatically insert the exposed core wire WC into the sleeve SV. Therefore, the operator can easily insert the exposed core wire WC into the sleeve SV.

(Sleeve installation method) Referring to Fig. 1, the sleeve installation method in the first embodiment will be described.

In the first step ST1, the sleeve SV is supported by the sleeve support 21. Fig. 1(a) shows the state after the first step ST1 is executed.

In the second step ST2, the first sliding rod 4 is pulled to the side of the base 2 to move the first electric wire W1 held by the first electric wire holding tool 7a in the second direction, thereby exposing the core wire WC1 of the first electric wire W1 Insert to the first end of the sleeve SV. Fig. 1(b) shows the state after the second step ST2 is executed. In addition, the second step ST2 is performed by, for example, operating the slide bar operating portion 6 (more specifically, the first slide bar operating portion 6a).

In the third step ST3, the second sliding rod 5 is moved in a direction protruding from the base 2 side, thereby moving the second electric wire W2 held by the second electric wire holding tool 7b in the second direction. Fig. 1(c) shows the state after the third step ST3 is executed. In addition, the third step ST3 is performed, for example, by operating the slide bar operating portion 6 (more specifically, the second slide bar operating portion 6b).

Furthermore, after the execution of the third step ST3, when the end of the exposed core wire WC2 and the end of the sleeve SV in the second direction are not facing each other, use a remote operation tool to expose the end of the core wire WC2 It is only necessary to move to a position facing the end of the sleeve SV in the second direction. More specifically, a remote operation tool may be used to move the end of the exposed core wire WC2, and the second core wire support 26b may support the end.

In the fourth step ST4, the second sliding rod 5 is pulled toward the base 2 to move the second wire W2 held by the second wire gripping tool 7b in the first direction, thereby exposing the core wire WC2 of the second wire W2 Insert into the second end of the sleeve SV. Fig. 1(d) shows the state after the fourth step ST4 is executed. In addition, the fourth step ST4 is performed, for example, by operating the slide bar operating portion 6 (more specifically, the second slide bar operating portion 6b).

As described above, in the sleeve installation method of the first embodiment, the overall slack of the first electric wire W1 and the second electric wire W2 can be suppressed, and the sleeve SV can be installed on the first electric wire with a simple operation.

Next, the sleeve support 21 and the core wire support 26 will be described with reference to FIGS. 3 to 5.

In the example shown in FIG. 3, the sleeve support tool 21 is equipped with the attachment part 23 attached to the rod-shaped part 20, the support part 210 which supports the sleeve SV, etc.. The mounting portion 23 is provided with a through hole 231 (refer to FIG. 4) for accommodating a part of the rod-shaped portion 20. The sleeve support 21 may be adjusted in position along the first direction with respect to the rod-shaped portion 20. In this case, the position of the sleeve support 21 can be adjusted corresponding to the length of the sleeve SV actually used. Accordingly, the versatility of the sleeve installation tool 1B can be improved. In addition, the sleeve support 21 may be detachably attached to the rod-shaped portion 20. In this case, it is possible to fit the most suitable sleeve support 21 to the rod-shaped portion 20 corresponding to the diameter of the sleeve SV actually used. Accordingly, the versatility of the sleeve installation tool 1B can be improved.

A sleeve supporter operating portion 212 is provided on the support portion 210, and the sleeve supporter operating portion 212 can change the state of the support portion between a closed state and an open state. When the supporting portion 210 is in the closed state, the supporting portion 210 restricts the sleeve SV, so that the sleeve SV cannot substantially move relative to the supporting portion 210. On the other hand, when the support part 210 is in an open state, the sleeve SV can be placed on the support part 210 or the sleeve SV can be removed from the support part 210. In the example described in FIG. 3, the sleeve support operating portion 212 is an eye bolt or eye nut having a through hole, and the through hole can receive the tip of the remote operating tool.

The second portion 216 is provided with a tapered surface 216a, whereby even when the end of the exposed core wire WC is expanded or bent, the exposed core wire WC can be smoothly inserted into the second portion 216. Furthermore, the core wire guide path 217 defined by the inner surface of the second portion 216 and the sleeve accommodating portion 215 defined by the inner surface of the first portion 214 are in communication with each other. Preferably, the inner surface of the first portion 214 has an end surface support surface 214a and an outer peripheral surface support surface 214b. The end surface support surface 214a is opposite to the end surface of the sleeve SV, and the outer peripheral surface support surface 214b is opposite to the sleeve SV. The outer peripheral surfaces of the SV face each other.

In the example shown in FIG. 3, the core wire support 26 is equipped with the attachment part 23 attached to the rod-shaped part 20 of the base part 2, and the support part 260 which supports exposed core wire WC and/or the covered electric wire. In the example described in FIG. 3, the attachment portion 23 of the core wire support 26 and the attachment portion 23 of the sleeve support 21 are the same. In other words, the core wire support 26 and the sleeve support 21 share the mounting portion 23. In this case, in a state where the positional relationship between the sleeve supporter 21 and the core wire supporter 26 has been maintained, the mounting portion 23 can be mounted on the rod-shaped portion 20. Furthermore, as shown in the example described in FIG. 1, the attachment portion of the core wire support 26 and the attachment portion of the sleeve support 21 may be independent individuals.

The support portion 260 is provided with a core wire support device operating portion 262 which can change the state of the support portion between a closed state and an open state. When the supporting portion 260 is in the closed state, the supporting portion 260 restricts the exposed core wire WC and/or the covered wire, so that the exposed core wire WC cannot move relative to the supporting portion 260 in a direction perpendicular to the first direction. On the other hand, when the supporting part 260 is in an open state, the exposed core wire WC and/or the covered electric wire may be placed on the supporting part 260 or removed from the supporting part 260 to expose the exposed core wire WC and/or the covered electric wire. In the example described in FIG. 3, the core wire support operating portion 262 is an eye bolt or eye nut having a through hole, and the through hole can accommodate the tip of the remote operating tool.

Preferably, the supporting portion 260 includes a core wire accommodating portion 267 into which the core wire WC and/or the covered electric wire can be inserted and exposed. In addition, although not shown in FIG. 3, the inner surface of the core wire accommodating portion 267 may be provided with a tapered surface whose diameter decreases toward the support portion 210 of the sleeve SV. When the core wire accommodating portion 267 has a tapered surface, the exposed core wire WC can be smoothly inserted into the core wire accommodating portion 267.

In the example described in FIG. 3, a gap G is provided between the support portion 260 of the core wire support 26 and the support portion 210 of the sleeve support 21. With the existence of the gap G, the operator can confirm whether the exposed core wire WC inserted from the core wire support 26 side has reached the sleeve support 21. In other words, the operator can confirm whether the work of inserting the exposed core wire WC into the sleeve SV is smoothly performed. Furthermore, there may be no gap G.

The sleeve support 21 will be further described with reference to FIG. 4. In the example shown in FIG. 4, the support part 210 which supports the sleeve SV is equipped with the 1st division body 218a and the 2nd division body 218b. In addition, by operating the sleeve support operating portion 212, the interval between the first divided body 218a and the second divided body 218b can be adjusted. In the example described in FIG. 4, the first divided body 218a and the second divided body 218b can be approached or separated along a direction (third direction) perpendicular to the first direction. Furthermore, the distance between the first divided body 218a and the second divided body 218b has been reduced, which corresponds to the closed state where the sleeve SV is restricted. The gap between the first divided body 218a and the second divided body 218b The state in which the interval is enlarged corresponds to the open state in which the restriction of the sleeve SV is released.

As shown in FIG. 4, one of the first divided body 218a and the second divided body 218b may also be provided with a guide member 219 (for example, a guide plate), and the guide member 219 can guide the sleeve SV Insertion of the cartridge housing 215. One of the first divided body 218a and the second divided body 218b is provided with the guide member 219, whereby the sleeve SV can be smoothly inserted into the sleeve receiving portion 215. Furthermore, in the example described in FIG. 4, the guide member 219 is provided with a guide surface 219c perpendicular to the third direction.

The core wire support 26 will be further described with reference to FIG. 5. In the example shown in FIG. 5, the support part 260 which supports the exposed core wire WC and/or the covered electric wire is equipped with the 1st divided body 268a and the 2nd divided body 268b. In addition, by operating the core wire support operating portion 262, the interval between the first divided body 268a and the second divided body 268b can be adjusted. In the example described in FIG. 5, the first divided body 268a and the second divided body 268b can approach or separate in a direction perpendicular to the first direction (third direction). Furthermore, the distance between the first divided body 268a and the second divided body 268b has been reduced, which corresponds to the closed state where the exposed core wire WC and/or the covered electric wire is restricted. The first divided body 268a and the second divided body 268a The state in which the interval between the bodies 268b has been enlarged corresponds to the open state in which the restriction on exposing the core wire WC and/or the covered electric wire is released.

As shown in FIG. 5, one of the first divided body 268a and the second divided body 268b may also be provided with a guide member 269 (for example, a guide plate), and the guide member 269 can guide and expose the core wires WC and/ Or the insertion of the covered wire into the core wire accommodating portion 267. One of the first divided body 268a and the second divided body 268b is provided with the guide member 269, whereby the exposed core wire WC and/or the covered electric wire can be smoothly inserted into the core wire receiving portion 267. Furthermore, in the example described in FIG. 5, the guide member 269 is provided with a guide surface 269c perpendicular to the third direction.

The sleeve support 21 and/or the core wire support 26 described in FIGS. 3 to 5 can be adopted as the second sleeve support 21 b and/or the second core wire support 26 b described in FIG. 2. In addition, a mirror image of the sleeve support 21 and/or the core wire support 26 described in FIGS. 3 to 5 can be adopted as the first sleeve support 21a and/or the first core wire support 26a described in FIG. 2 .

Furthermore, in the examples described in FIGS. 2 to 5, the sleeve supporter operating portion 212 and the core wire supporter operating portion 262 are separate operating portions. Alternatively, the sleeve supporter operating portion 212 and the core wire supporter operating portion 262 may be constituted by one operating portion. In this case, by operating one operation unit, the interval between the first split body 218a and the second split body 218b, and the interval between the first split body 268a and the second split body 268b can be adjusted simultaneously . Furthermore, it is also possible to configure the operating parts corresponding to one side of the sleeve supporter and the core wire supporter (for example, the first sleeve supporter 21a and the first core wire supporter 26a) by a single operating portion, The operating parts (212, 262) of the corresponding to the other side of the sleeve supporter and the core wire supporter (for example, the second sleeve supporter 21b and the second core wire supporter 26b) constitute the operation portion.

(1st sliding bar 4) As shown in Fig. 2, the first sliding rod 4 is an elongated member extending in the first direction. The first sliding rod 4 may be hollow or solid. In the example described in FIG. 2, a part of the first sliding rod 4 is inserted into the inside of the base 2. The first sliding bar 4 and the first sliding bar operating portion 6a are configured to transmit operating force, and by operating the first sliding bar operating portion 6a, the protrusion amount of the first sliding bar 4 from the base 2 can be changed. A first electric wire gripping tool 7a is connected to the front end of the first sliding rod 4.

(Second Slider 5) The second sliding rod 5 is an elongated member extending in the second direction. The second sliding rod 5 may be hollow or solid. In the example described in FIG. 2, a part of the second sliding rod 5 is inserted into the inside of the base 2. The second sliding bar 5 and the second sliding bar operating portion 6b are configured to transmit operating force, and by operating the second sliding bar operating portion 6b, the protrusion amount of the second sliding bar 5 from the base 2 can be changed. A second electric wire holding tool 7b is connected to the front end of the second sliding rod 5.

(Sliding stick operation part 6) In the example described in FIG. 2, the first slide bar operating portion 6a and the second slide bar operating portion 6b are eye bolts or eye nuts having through holes, respectively. The front end of a remote operation tool can be accommodated.

An example of a mechanism in which the first sliding rod operation portion 6a is operated using a remote operation tool to slide the first sliding rod 4 with respect to the base 2 will be described. In an example, the following scenario is assumed: (A) A first bevel gear is provided on the first sliding bar operating portion 6a, and the first bevel gear is rotatable about the rotation axis AX1 together with the first sliding bar operating portion 6a, ( B) A second bevel gear is arranged on the inner side of the base 2. The second bevel gear is connected to the first bevel gear so that load can be transmitted. (C) The second bevel gear can be wound with a threaded rod with external threads on the outer circumference The longitudinal axis of the threaded rod rotates, and (D) the first sliding rod 4 is screwed to the threaded rod. In this case, after the first sliding rod operating portion 6a is rotated around the rotation axis AX1 by the remote operation tool, the first bevel gear will rotate around the rotation axis AX1, and the second bevel gear and the threaded rod will be around the threaded rod The long side direction axis to rotate. When the threaded rod is rotated, the first sliding rod 4 screwed on the threaded rod will move in the direction of being pulled toward the base 2 (or in the direction protruding from the base 2). In this way, the first sliding rod 4 can relatively slide and move with respect to the base 2.

In addition, as a mechanism for operating the first sliding rod operating portion 6a to thereby slide the first sliding rod 4 with respect to the base portion 2, any mechanism other than the aforementioned mechanism may be adopted.

As a mechanism for operating the second sliding bar operating portion 6b with a remote operating tool, thereby sliding the second sliding bar 5 relative to the base 2, it is possible to adopt and operate the first sliding bar operating portion 6a, thereby making the first The mechanism of sliding movement of the sliding rod 4 relative to the base 2 is the same.

(Wire holder 7) The first electric wire gripping tool 7a includes a first gripping piece 71 and a second gripping piece 72, and the first gripping piece 71 and the second gripping piece 72 clamp the first electric wire W1 (more specifically, the first The part of the wire that does not expose the core wire). In the example described in Fig. 2, the first electric wire gripping tool 7a includes a parallel link mechanism. In addition, when the first wire W1 arranged between the first grip piece 71 and the second grip piece 72 wants to move in the first direction with respect to the first wire gripping tool 7a, the parallel link mechanism acts The force with which the first gripping piece 71 and the second gripping piece 72 grip the first electric wire W1 increases.

The first electric wire holding tool 7a is connected to the first sliding rod 4 through the first connecting portion 74. Furthermore, the connection between the first wire holding tool 7a and the first sliding rod 4 may be connected to swing around a swing axis perpendicular to the first direction, or may be a non-swing connection. The first electric wire holding tool 7a may be included in the sleeve installation tool 1B, or may not be included in the sleeve installation tool 1B. When the sleeve installation tool 1B does not include the first electric wire gripping tool 7a, the existing first electric wire gripping tool may be attached to the sleeve installation tool 1B.

The second electric wire gripping tool 7b is connected to the second sliding rod 5 through the second connecting portion 76. Since the configuration of the second electric wire gripping tool 7b is the same as that of the first electric wire gripping tool 7a, the repeated description of the second electric wire gripping tool 7b is omitted. Furthermore, one of the connection between the first electric wire holding tool 7a and the first sliding rod 4 and the connection between the second electric wire holding tool 7b and the second sliding rod 5 may also be a vertical The connection on the swing axis in the first direction is swingable, and the connection on the other side is a non-swing connection.

(Wire support 8) The wire support tool 8 is a member that supports the first wire W1 or the second wire W2 in the area between the first wire gripping tool 7a and the second wire gripping tool 7b. The wire support 8 may be a member that supports the wire by directly contacting the wire (the first wire W1 or the second wire W2), or may be a member that defines the position of the wire by surrounding the wire.

In the example described in FIG. 2, the number of wire supports 8 is three (a first wire support 8a, a second wire support 8b, and a third wire support 8c). As an alternative, the number of wire supports 8 can also be one, two, or four or more. In the example described in FIG. 2, each wire supporter (the first wire supporter 8a, the second wire supporter 8b, the third wire supporter 8c, etc.) is attached to the base 2 of the sleeve installation tool 1B. In addition, the first wire support 8a is arranged on the first direction side than the first core wire support 26a, and the second wire support 8b (and the third wire support 8c) is arranged more than the second core wire support 26b. Further to the second direction side.

The first wire support 8a can support the end of the first wire W1 when the first wire W1 and the second wire W2 are formed by cutting the wires (wherein, the "support end" includes "the position of the predetermined end" "). The second wire supporter 8b supports the end of the second wire W2 after the wire is cut (here, the "support end" includes the "predetermined end position").

The third wire support 8c is arranged on the opposite side of the second wire support 8b with respect to the base 2. In other words, when the second wire support 8b is located above the base 2, the third wire support 8c is configured to be located below the base 2. Imagine the following situation: use a remote operation tool to move the second wire W2 to change the position of the end of the second wire W2 from the position supported by the second wire support 8b to the third wire support 8c The location of support. In this case, the end of the first electric wire W1 supported by the first electric wire support 8a and the end of the second electric wire W2 supported by the third electric wire support 8c can be appropriately separated (for example, vertically divided) .

As an alternative or as an additional solution, the first wire support 8a and/or the second wire support 8b may also be rotated around the longitudinal axis of the base 2. In this case, by rotating the first wire support 8a or the second wire support 8b around the longitudinal axis of the base 2, the end of the first wire W1 supported by the first wire support 8a can be , And the end of the second electric wire W2 supported by the second electric wire support 8b is split (for example, up and down). Furthermore, when the first wire support 8a and/or the second wire support 8b are rotatable about the longitudinal axis of the base 2, the third wire support 8c may be omitted.

In the example shown in FIG. 6, the 2nd wire support 8b is equipped with the accommodation space SP which accommodates an electric wire (for example, 2nd electric wire W2). In the example shown in FIG. 6, the second wire support 8b includes a frame member 81b and an opening and closing member 82b that can freely open and close the opening of the frame member 81b. In addition, the housing space SP is defined by the frame member 81b and the opening and closing member 82b.

Moreover, in the example described in FIG. 6, the 3rd electric wire support 8c is equipped with the accommodation space which accommodates an electric wire (for example, 2nd electric wire W2). In the example shown in FIG. 6, the 3rd wire support 8c is equipped with the frame member 81c and the opening and closing member 82c which can open and close the opening part of the frame member 81c. In addition, the housing space is defined by the frame member 81c and the opening and closing member 82c. In the example described in FIG. 2 and FIG. 6, the 3rd wire support 8c is comprised integrally with the 2nd wire support 8b. Alternatively, the third wire support 8c may be integrally configured with the first wire support 8a, or may be configured independently of the first wire support 8a and the second wire support 8b.

The structure of the first wire support 8a is the same as the structure of the second wire support 8b. Therefore, detailed description of the first wire support 8a is omitted here. As shown in FIG. 2, the first wire support 8a includes a frame member 81a and an opening and closing member 82a that can freely open and close the opening of the frame member 81a.

(Sleeve cover holder 9) In the example described in FIG. 2, the sleeve installation tool 1B is equipped with the sleeve cover gripping tool 9 which grips the sleeve cover SC (refer FIG. 13 etc.). The sleeve cover gripping tool 9 grips the sleeve cover SC arranged along the first wire W1 or the second wire W2. The sleeve cover gripping tool 9 is attached to, for example, any of the first sliding rod 4, the second sliding rod 5, the first electric wire gripping tool 7a, and the second electric wire gripping tool 7b.

When the sleeve installation tool 1B is equipped with the sleeve cover gripping tool 9, the exposed core wire WC1 of the first electric wire and the exposed core wire WC2 of the second electric wire are inserted into the sleeve SV, and the sleeve cover SC can be suppressed The movement of the sleeve cover SC will not hinder the operation. In addition, when the sleeve SV into which the exposed core wire WC1 and the exposed core wire WC2 are inserted is compressed by a compression tool, the movement of the sleeve cover SC can be suppressed, so that the sleeve cover SC does not interfere with the operation. After the sleeve SV is compressed, the sleeve cover SC will move to a position covering the sleeve SV, and the sleeve cover SC protects the connection between the sleeve SV and the exposed core wires (WC1, WC2).

In the example described in FIG. 2, the sleeve cover gripping tool 9 includes a first sleeve cover gripping tool 9a that grips the first sleeve cover SC1 (refer to FIG. 13 etc.), and a second sleeve cover The second sleeve cover gripping tool 9b of SC2 (see Fig. 15 etc.). The first sleeve cover holding tool 9a is attached to, for example, the first sliding rod 4 or the first wire holding tool 7a, and the second sleeve cover holding tool 9b is attached to, for example, the second sliding rod 5 or the second wire holding tool. 7b.

When the sleeve cover gripping tool 9 includes the first sleeve cover gripping tool 9a and the second sleeve cover gripping tool 9b, a split-type sleeve cover can be used as the sleeve cover. It is divided into a first sleeve cover SC1 and a second sleeve cover SC2. When a split-type sleeve cover is used, the length of each sleeve cover (the first sleeve cover SC1 and the second sleeve cover SC2) becomes shorter. According to this, even if the electric wire is slightly bent, the operation of moving the sleeve cover along the electric wire (the first electric wire W1 or the second electric wire W2) can be performed relatively easily. Furthermore, when the first sleeve cover SC1 and the second sleeve cover SC2 are moved to the position covering the sleeve SV, the first sleeve cover SC1 and the second sleeve cover SC2 are connected to each other.

An example of the structure of the sleeve cover gripping tool 9 will be described in more detail with reference to FIG. 7.

In the example described in FIG. 7, the sleeve cover gripping tool 9 is provided with: a mounting portion 93 attached to a sliding rod (for example, the second sliding rod 5) or a wire gripping tool (for example, the second wire gripping tool 7b), and a support The sleeve covers the support portion 95 of the SC.

The support portion 95 is provided with a sleeve cover gripping tool operating portion 952 that can change the state of the support portion 95 between a closed state and an open state. When the supporting portion 95 is in the closed state, the supporting portion 95 will hold the sleeve cover SC. On the other hand, when the support portion 95 is in an open state, the sleeve cover SC can be inserted into the support portion 95 or the sleeve cover SC can be removed from the support portion 95. In the example described in FIG. 7, the sleeve cover gripping tool operating portion 952 is an eye bolt or eye nut having a through hole, and the through hole can accommodate the tip of the remote operating tool .

In the example shown in FIG. 7, the support part 95 which supports the sleeve cover SC is equipped with the 1st divided body 958a and the 2nd divided body 958b. In addition, by operating the sleeve cover gripping tool operating portion 952, the interval between the first divided body 958a and the second divided body 958b can be adjusted. In the example described in FIG. 7, the first divided body 958a and the second divided body 958b can approach or separate in a direction perpendicular to the first direction (third direction). Furthermore, the distance between the first divided body 958a and the second divided body 958b has been reduced, which corresponds to the closed state in which the sleeve cover SC is gripped. The difference between the first divided body 958a and the second divided body 958b The state in which the interval between the two is enlarged corresponds to the open state in which the grip state of the sleeve cover SC is released.

The sleeve cover gripping tool 9 described in FIG. 7 can be adopted as the second sleeve cover gripping tool 9b described in FIG. 2. Furthermore, the mirror image of the sleeve cover gripping tool 9 described in FIG. 7 can be adopted as the first sleeve cover gripping tool 9a described in FIG. 2.

The sleeve installation tool 1B in the second embodiment can exhibit the same effects as the sleeve installation tool 1A in the first embodiment. In addition, when the sleeve mounting tool 1B of the second embodiment includes at least one wire support 8, the end of the first wire W1 and the end of the second wire W2 can be separated. In this case, it is possible to suppress unexpected contact (short circuit) between the end of the first electric wire W1 and the end of the second electric wire W2. Furthermore, when the sleeve installation tool 1B of the second embodiment includes at least one sleeve cover gripping tool 9, the movement of the sleeve cover SC can be prevented. Therefore, in the work of inserting the exposed core wire into the sleeve SV or the work of compressing the sleeve SV, the sleeve cover SC does not hinder the work. In addition, the configuration of the wire support tool 8 and/or the sleeve cover gripping tool 9 in the second embodiment may be adopted in the first embodiment.

(Sleeve installation method) An example of the sleeve mounting method in the second embodiment will be described with reference to FIGS. 8 to 17. Fig. 8 is a flowchart showing an example of the sleeve installation method in the second embodiment. Fig. 9 to Fig. 17 are diagrams respectively showing one step of the sleeve installation method.

In the first step ST101, the sleeve installation tool 1B is attached to the electric wire W. This installation is performed by attaching the first electric wire holding tool 7a and the second electric wire holding tool 7b to the electric wire W. In the example shown in FIG. 9, the sleeve installation tool 1B is attached to the electric wire W, and the part (exposed part A) of the core wire WC is exposed so that the coating layer of the electric wire W may be peeled to oppose. Alternatively, after mounting the sleeve installation tool 1B on the wire W, the coating layer of the wire W may be peeled off to form the exposed portion A.

In the first step ST101, it is preferable that the wire W is supported by the wire support 8 (specifically, the first wire support 8a and the second wire support 8b). The step of supporting the electric wire W by the electric wire support 8 includes, for example, moving the opening and closing members (82a, 82b) to the open position and moving the electric wire W into the frame members (81a, 81b), and then the opening and closing members (82a) , 82b) Move to the closed position to execute. Furthermore, the step of supporting the wire W by the wire support 8 and the step of mounting the first wire holding device 7a and the second wire holding device 7b to the wire W may be performed first.

In the second step ST102, the interval between the first wire gripping tool 7a and the second wire gripping tool 7b is reduced, thereby bending the portion of the wire W between the first wire gripping tool 7a and the second wire gripping tool 7b (Refer to Figure 10). The second step ST102 is performed by operating the sliding bar operating part 6 (for example, the first sliding rod operating part 6a), pulling the first sliding rod 4 to the base 2 side, and operating the sliding rod operating part 6 (for example, the first sliding rod operating part 6a). 2 Slide bar operation part 6b), pull the second slide bar 5 to the base 2 side. Furthermore, for the pulling-in step of the first sliding bar 4 and the pulling-in step of the second sliding bar 5, either step may be performed first. As an alternative, the pulling-in step of the first sliding bar 4 and the pulling-in step of the second sliding bar 5 may be repeated alternately.

In the third step ST103, the wire W is cut by a cutting tool between the first wire gripping tool 7a and the second wire gripping tool 7b. By this cutting, the electric wire W is separated into the first electric wire W1 and the second electric wire W2. Furthermore, the cutting position is preferably a part of the wire W where the core wire WC is exposed (exposed part A). In this case, by cutting, the end of the first electric wire W1 becomes the exposed core wire WC1, and the end of the second electric wire W2 becomes the exposed core wire WC2. Furthermore, instead of peeling off the coating layer of the wire before the wire is cut, after the wire is cut, the end of the first wire W1 and the end of the second wire W2 are stripped off. under. In this case, there is no need to peel off the coating layer of the electric wire before the first step ST101.

The cutting tool used in the third step ST103 is, for example, a cutting tool attached to the tip of the remote operation tool. Fig. 11 shows the state after the third step ST103 is executed.

As shown in FIG. 12, in the fourth step ST104, the end of the first electric wire W1 and the end of the second electric wire W2 are separated (for example, vertically separated). The fourth step ST104 is performed, for example, by moving the end of the second electric wire W2 from the second electric wire support 8b to the third electric wire support 8c, and the second electric wire is supported by the third electric wire support 8c The end of W2. Alternatively, the fourth step ST104 may be performed by rotating the second wire support 8b that supports the end of the second wire W2 around the longitudinal axis of the base 2.

In the fourth step ST104, as an additional solution, in order to increase the distance between the end of the first electric wire W1 and the end of the second electric wire W2, the first sliding rod 4 and/or the second sliding rod 5 Move in the direction protruding from the base 2. This movement is performed by operating the sliding bar operating portion 6 (specifically, the first sliding bar operating portion 6a and/or the second sliding bar operating portion 6b).

After the execution of the fourth step ST104, the insulating cap IC (see FIG. 13) may be attached to one of the end of the first electric wire W1 and the end of the second electric wire W2. Alternatively, an insulating cap may be attached to both the end of the first electric wire W1 and the second electric wire W2.

In addition, during the execution of the first step ST101 to the fourth step ST104, the sleeve support 21 and the core wire support 26 are preferably in an open state. Similarly, in the execution of the first step ST101 to the fourth step ST104 described above, the sleeve cover gripping tool 9 is preferably in an open state.

As shown in FIG. 13, in the fifth step ST105, the first sleeve cover SC1 is pressed in, the first wire W1 passes through the inside of the first sleeve cover SC1, and then the first sleeve cover The gripping tool 9a grips the first sleeve cover SC1. The fifth step ST105 is performed by using a remote operation tool such as an insulating clamp.

Furthermore, when an insulating cap is attached to the end of the first electric wire W1, the insulating cap must be removed from the end of the first electric wire W1 before the execution of the fifth step ST105. Moreover, as indicated by the arrow B, the first sliding rod 4 may be moved in a direction protruding from the base 2 before the execution of the fifth step ST105.

As shown in FIG. 13, in the sixth step ST106, the sleeve SV is supported by the sleeve support 21. In the sixth step ST106, first, the sleeve SV is placed on the sleeve support 21 using a remote operation tool such as an insulating clamp. After that, using the remote operation tool, the sleeve supporter operating portion 212 is operated to change the state of the sleeve supporter 21 from the open state to the closed state. As a result, the sleeve support 21 can position and support the sleeve SV. Furthermore, when the sleeve supporter 21 includes the first sleeve supporter 21a and the second sleeve supporter 21b, it is positioned by the first sleeve supporter 21a and the second sleeve supporter 21b Support sleeve SV.

As shown in FIG. 13, in the seventh step ST107, the exposed core wire WC1 of the first electric wire W1 is supported by the first core wire support 26a. In the seventh step ST107, first, using the remote operation tool, the exposed core wire WC1 is moved into the first core wire support 26a. After that, using the remote operation tool, the first core wire support operating portion 262a is operated to change the state of the first core wire support 26a from the open state to the closed state. As a result, the exposed core wire WC1 can be restricted by the first core wire support 26a. With this restriction, it is possible to align the sleeve SV and the exposed core wire WC1, and correct the bend of the first electric wire W1. As a result, the subsequent steps (the step of inserting the exposed core wire WC1 into the sleeve SV) can be performed smoothly.

The seventh step ST107 may be executed before the sixth step ST106.

As shown in Fig. 14, in the eighth step ST108, the exposed core wire WC1 of the first electric wire W1 is inserted into the sleeve SV. The eighth step ST108 is performed by operating the sliding bar operating portion 6 (for example, the first sliding bar operating portion 6a), and pulling the first sliding bar 4 toward the base 2 side. By executing the eighth step ST108, the downward bending of the first electric wire W1 and the second electric wire W2 can be reduced. In addition, by executing the eighth step ST108, the first sleeve cover SC1 can approach the first core wire support 26a.

The first sleeve cover SC1 gripped by the first sleeve cover gripping tool 9a may also function as a restricting tool for maintaining the first electric wire W1 in a linear shape. Accordingly, when the sleeve installation tool 1B is provided with the first sleeve cover gripping tool 9a, the step of inserting the exposed core wire WC1 into the sleeve SV can be performed more smoothly.

As shown in FIG. 15, in the ninth step ST109, the slide bar operating portion 6 (for example, the second slide bar operating portion 6b) is operated to move the second slide bar 5 in a direction protruding from the base portion 2. By executing the ninth step ST109, the exposed core wire WC2 of the second electric wire W2 can be retracted to the second direction side of the sleeve SV. Furthermore, by the execution of the ninth step ST109, the downward bending of the first electric wire W1 and the second electric wire W2 increases.

Furthermore, when an insulating cap is attached to the end of the second electric wire W2, the insulating cap is removed from the end of the second electric wire W2 before the execution of the ninth step ST109.

In the tenth step ST110, the second sleeve cover SC2 is pressed in, the second wire W2 is passed through the inside of the second sleeve cover SC2, and then the second sleeve cover gripping tool 9b is used to hold the 2Sleeve cover SC2. The tenth step ST110 is performed using, for example, a remote operation tool such as an insulating clamp. In addition, the tenth step ST110 is executed after the end of the second electric wire W2 is moved above the second sliding rod 5. The movement of the end of the second electric wire W2 includes, for example, moving the end of the second electric wire W2 from the third electric wire support 8c to the second electric wire support 8b.

In the eleventh step ST111, the exposed core wire WC2 of the second electric wire W2 is supported by the second core wire support 26b. In the 11th step ST111, first, using a remote operation tool, the exposed core wire WC2 is moved into the second core wire support 26b. After that, using the remote operation tool, the second core wire support operating portion 262b is operated to change the state of the second core wire support 26b from the open state to the closed state. As a result, the exposed core wire WC2 can be restricted by the second core wire support 26b. With this restriction, it is possible to align the sleeve SV and the exposed core wire WC2, and to correct the bend of the second electric wire W2.

As shown in FIG. 16, in the 12th step ST112, the exposed core wire WC2 of the 2nd electric wire W2 is inserted in the sleeve SV. The twelfth step ST112 is performed by operating the sliding bar operating portion 6 (for example, the second sliding bar operating portion 6b), and pulling the second sliding bar 5 toward the base 2 side. By performing the twelfth step ST112, the downward bending of the first electric wire W1 and the second electric wire W2 can be reduced. In addition, by executing the twelfth step ST112, the second sleeve cover SC2 can approach the second core wire support 26b.

The second sleeve cover SC2 gripped by the second sleeve cover gripping tool 9b may also function as a restricting tool for maintaining the second electric wire W2 in a linear shape. Accordingly, when the sleeve installation tool 1B is provided with the second sleeve cover gripping tool 9b, the step of inserting the exposed core wire WC2 into the sleeve SV can be performed more smoothly.

After the execution of the twelfth step ST112, it is also possible to remove or reduce the restriction of the sleeve support (21a, 21b) on the sleeve SV, the restriction of the core support (26a, 26b) on the exposed core wire, and the grip of the sleeve cover Tools (9a, 9b) restrict the sleeve cover. The release or reduction of these restrictions is performed by operating the sleeve supporter operating portion 212, the core wire supporter operating portion 262, and the sleeve cover gripper operating portion 952 with a remote operating tool. With these restrictions removed or reduced, pull the first sliding rod 4 and/or the second sliding rod 5 to the side of the base 2 to expose the core wire WC1 and the core wire WC2 to insert it into the sleeve SV deeper position. In addition, the sleeve SV is compressed using the sleeve compression device, thereby connecting the first wire W1 and the second wire W2 that were originally cut.

In the 13th step ST113, the sleeve mounting tool 1B is removed from the first electric wire W1 and the second electric wire W2.

In the fourteenth step ST114, the first sleeve cover SC1 and the second sleeve cover SC2 are moved to the position covering the sleeve SV, and the first sleeve cover SC1 and the second sleeve cover SC2 are aligned with each other. link.

In addition, arbitrary constituent elements used in each embodiment may be combined with other embodiments, and arbitrary constituent elements may be omitted in each embodiment.

For example, in the example described in FIG. 1 or FIG. 2, it is described that the slide bar operating portion 6 includes a first slide bar operating portion 6a that slides the first slide bar 4, and a first slide bar operating portion 6a that slides the second slide bar 5. 2 An example of the sliding bar operating part 6b. As an alternative, as shown in FIG. 18, one sliding bar operating portion 6c may independently operate the first sliding bar 4 and the second sliding bar 5.

In the example described in FIG. 18, the slide bar operating portion 6c can be selectively connected to the first load transmission mechanism 61 or the second load transmission mechanism 62, wherein the first load transmission mechanism 61 can drive the first slide bar 4. The aforementioned second load transmission mechanism 62 can drive the second sliding rod 5. More specifically, the slide bar operating portion 6c includes an operating portion side engaging portion 63, the first load transmission mechanism 61 includes a first engaging portion 61a that can be engaged with the operating portion side engaging portion 63, and a second load The transmission mechanism 62 includes a second engaging portion 62a that can be engaged with the operating portion-side engaging portion 63. In addition, the operation portion side engaging portion 63 can be selectively engaged with the first engaging portion 61a or the second engaging portion 62a. In this way, the operating force acting on the sliding bar operating portion 6c can be selectively transmitted to the first sliding bar 4 or the second sliding bar 5 through the first engaging portion 61a or the second engaging portion 62a.

In the example described in FIG. 18, the slide bar operating portion 6 c is installed so as to be relatively movable with respect to the base 2. Between the slide bar operating portion 6c and the base portion 2, there is an imparting potential energy member 64, which imparts the slide bar operating portion 6c in a direction toward the first engaging portion 61a or the second engaging portion 62a. And potential energy. Moreover, in the example described in FIG. 18, the magnet 65 is arrange|positioned on the operation part side engagement part 63, and this magnet 65 is attracted to the 1st engagement part 61a (or the 2nd engagement part 62a). As an alternative or in addition, magnets for sucking the operating portion-side engaging portion 63 may be respectively arranged on the first engaging portion 61a and the second engaging portion 62a.

In the example described in FIG. 18, the first load transmission mechanism 61 includes: a first bevel gear 61b that rotates together with the first engagement portion 61a; and a second bevel gear 61e that is screwed to the first slide bar 4 The first screw rod 61c rotates together. Therefore, when the slide bar operating portion 6c is operated to rotate around the first axis AT1, the first engaging portion 61a engaged with the operating portion-side engaging portion 63 will go around the first bevel gear 61b together with the first bevel gear 61b. Axis AT1 rotates. In the example described in FIG. 18, the first bevel gear 61b and the second bevel gear 61e mesh with each other. Accordingly, when the first bevel gear 61b rotates around the first axis AT1, the second bevel gear 61e engaged with the first bevel gear 61b and the first threaded rod 61c around the first axis AT1 perpendicular to the first axis. 2 axis AT2 to rotate. The threaded portion 61d of the first threaded rod 61c is screwed to the first sliding rod 4. Therefore, when the first screw rod 61c rotates around the second axis AT2, the first sliding rod 4 slides in the direction along the second axis AT2.

Similarly, in the example described in FIG. 18, the second load transmission mechanism 62 includes: a third bevel gear 62b that rotates with the second engagement portion 62a; and a fourth bevel gear 62e that is screwed to the second The second threaded rod 62c of the sliding rod 5 rotates together. Therefore, when the slide bar operating portion 6c is operated to rotate around the third axis AT3, the second engaging portion 62a engaged with the operating portion-side engaging portion 63 will move around the third bevel gear 62b together. Axis AT3 rotates. In the example described in FIG. 18, the third bevel gear 62b and the fourth bevel gear 62e mesh with each other. According to this, when the third bevel gear 62b rotates around the third axis AT3, the fourth bevel gear 62e engaged with the third bevel gear 62b and the second threaded rod 62c will go around the third axis perpendicular to the third axis AT3. 4 axis AT4 to rotate. The threaded portion 62d of the second threaded rod 62c is screwed to the second sliding rod 5. Therefore, when the second screw rod 62c rotates around the fourth axis AT4, the second sliding rod 5 will slide in the direction along the fourth axis AT4. Furthermore, the fourth axis AT4 and the second axis AT2 are axes arranged on a straight line.

In the example described in FIG. 18, it is assumed that the engagement target of the operation portion-side engagement portion 63 of the slide bar operation portion 6c is switched from the first engagement portion 61a to the second engagement portion 62a. In this case, first, use a remote control tool to move the sliding rod operating portion 6c away from the first engaging portion 61a against the potential energy imparting ability of the potential energy imparting member 64 and/or the attraction force of the magnet 65 . Next, using a remote operating tool, the slide bar operating portion 6c is slidably moved from the position facing the first engaging portion 61a to the position facing the second engaging portion 62a. Preferably, a guide portion such as a long hole is provided in the base portion 2 to guide the sliding movement of the slide bar operating portion 6c. Next, the sliding bar operating portion 6c is engaged with the second engaging portion 62a by the potential energy imparted by the potential energy member 64 and/or the attraction force of the magnet 65.

Since the operation of switching the engagement object of the operating portion side engaging portion 63 of the slide bar operating portion 6c from the second engaging portion 62a to the first engaging portion 61a is the same as switching the slide bar operating portion 6c on the operating portion side The operation of switching the engagement object of the engagement portion 63 from the first engagement portion 61a to the second engagement portion 62a is the same, and therefore, the repeated description is omitted.

FIG. 19 shows a modification example in which at least one of the sleeve support 21 and the core wire support 26 is mounted to the mounting portion 23 of the rod-shaped portion 20 of the base 2. In the example described in FIG. 19, the attachment portion 23 is attachable and detachable to the rod-shaped portion 20 of the base 2.

In the example described in FIG. 19, the mounting portion 23 includes: a mounting portion base member 23a to which at least one of the sleeve support 21 and the core wire support 26 is mounted; and a holding member 23b that can be opposed to the mounting portion The base member 23a moves relatively. When the holding member 23b is located at the holding position with respect to the mounting portion base member 23a, the mounting portion 23 is fixed to the rod-shaped portion 20 by the holding member 23b and the mounting portion base member 23a. On the other hand, when the gripping member 23b is located at the grip opening position relative to the mounting portion base member 23a, the mounting portion 23 can be removed from the rod-shaped portion 20 (or, the mounting portion 23 can be mounted to the rod-shaped portion 20) .

In the example shown in FIG. 19, the gripping member 23b is swingably attached to the mounting portion base member 23a, and the gripping member 23b can swing freely about the first swing axis AS1 relative to the mounting portion base member 23a. . The mounting portion base member 23a and the holding member 23b each have an inner surface (more specifically, an arc-shaped surface) complementary to the outer shape of the rod-shaped portion 20. An elastic body 24 a may be arranged on the inner surface of the mounting portion base member 23 a to suppress sliding with respect to the rod-shaped portion 20. Similarly, an elastic body 24b may be arranged on the inner surface of the gripping member 23b to suppress sliding with respect to the rod-shaped portion 20.

In the example shown in FIG. 19, the magnet 235 is arrange|positioned on the holding member 23b for holding the holding member 23b in a holding position. The magnet 235 is attracted by the mounting base member 23a to hold the gripping member 23b at the gripping position. As an alternative or as an additional solution, a magnet may also be arranged on the mounting portion base member 23a for holding the holding member 23b at the holding position.

In the example described in FIG. 19, the mounting portion 23 is provided with a lock member 25 which prevents the grip member 23b from moving from the grip position to the grip opening position. The locking member 25 is attached to the mounting portion base member 23a in a swingable manner, for example. In the example described in FIG. 19, the lock member 25 can swing freely about the second swing axis AS2 with respect to the mounting portion base member 23a.

When attaching the attaching portion 23 to the rod-shaped portion 20, first, the attaching portion base member 23a is arranged around the rod-shaped portion 20. Next, the grip member 23b is moved from the grip opening position to the grip position. In this way, the mounting part 23 can be mounted on the rod-shaped part 20. Next, the locking member 25 is moved from the locked open position to the locked position, thereby locking the holding member 23b so as not to move from the holding position.

When removing the mounting portion 23 from the rod-shaped portion 20, it is only necessary to perform an operation opposite to the operation of mounting the mounting portion 23 to the rod-shaped portion 20.

In the example shown in FIG. 19, the attachment part 23 is equipped with the attachment part base member 23a and the holding member 23b. Therefore, the mounting part 23 can be mounted to the rod-shaped part 20 of the base 2 by a simple operation, and the mounting part 23 can be removed from the rod-shaped part 20 of the base 2 by a simple operation. In addition, the attachment portion 23 can be attached to the rod-shaped portion 20 by a simple operation, which means that the position of the attachment portion 23 can be changed along the longitudinal direction of the rod-shaped portion 20 by a simple operation. In this case, it is possible to easily adjust the mounting position of the mounting portion 23 to the rod-shaped portion 20 in accordance with the length of the sleeve SV used.

FIG. 20 shows a modified example of the opening and closing operation mechanism M that opens and closes at least one of the sleeve support 21 and the core wire support 26. In the example described in FIG. 4 or FIG. 5, the opening and closing of the sleeve support 21 or the core support 26 is performed by rotating the operating parts (212, 262) such as eye bolts and eye nuts. On the other hand, in the example described in FIG. 20, opening and closing of the sleeve support 21 or the core wire support 26 is performed by a swing type operating lever (212a, 262a). The operating levers (212a, 262a) are, for example, toggle levers.

An example of a mechanism for opening and closing the sleeve support 21 or the core wire support 26 by the swing type operating lever (212a, 262a) will be described with reference to FIG. 20.

In the example described in FIG. 20, when the operating levers (212a, 262a) are located at the first position (for example, the upper position), the supports (21, 26) are in an open state. In the example described in FIG. 20, the open state of the supports (21, 26) refers to a state where the first divided bodies (218a, 268a) and the second divided bodies (218b, 268b) are separately arranged. In the example described in FIG. 20, when the operating levers (212a, 262a) are located at the second position (for example, the lower position), the supports (21, 26) are in the locked state. In the example described in FIG. 20, the locked state of the support (21, 26) refers to a state where the first split body (218a, 268a) and the second split body (218b, 268b) are arranged close to each other.

In the example described in FIG. 20, when the operating levers (212a, 262a) are moved from the first position (upper position) to the second position (lower position), the first pressing body 27a is the first split body (218a). , 268a) press in the direction toward the second split body, and the second pressing body 27b presses the second split body (218b, 268b) in the direction toward the first split body. In this way, the support (21, 26) becomes a locked state.

In the example shown in FIG. 20, the potential energy-imparting member 28 is arranged between the first divided body (218a, 268a) and the second divided body (218b, 268b). The potential energy-imparting member 28 is in the direction separating the first divided body (218a, 268a) and the second divided body (218b, 268b) from each other, and the first divided body (218a, 268a) and the second divided body (218b, 268b) ) Give potential energy. Therefore, when the operating levers (212a, 262a) move from the second position (lower position) to the first position (upper position), the potential energy-generating member 28 will move the first divided body (218a, 268a) away from the second position. The direction of the divided body is pressed, and the potential energy-imparting member 28 will press the second divided body (218b, 268b) in the direction away from the first divided body. In this way, the support (21, 26) becomes an open state.

In the example described in FIG. 20, the first shaft 29a to which the first pressing body 27a is fixed is pivoted to the first plug 29c, and the first plug 29c is attached to the operating levers (212a, 262a). In addition, the second pressing body 27b is slidable along the longitudinal direction of the first shaft 29a, and the second pressing body 27b is attached to the operating levers (212a, 262a) through the connecting member CN. More specifically, the connecting member CN is pivotally mounted to the second pressing body 27b through the second plug 29d, and is pivotally mounted to the operating lever (212a, 262a) through the third plug 29e.

In the example described in FIG. 20, by moving the operating levers (212a, 262a) from the first position (upper position) to the second position (lower position), the operating levers (212a, 262a) are moved around the third latch When 29e rotates, the first pin 29c will rotate around the third pin 29e. As a result, the first shaft 29a and the first pressing body 27a connected to the first plug 29c move in a direction approaching the second pressing body 27b. In this way, the supports (21, 26) are in a locked state.

In the example described in FIG. 20, a positioning stopper (more specifically, a centering pin CP) is provided on the support (21, 26). Therefore, when the support (21, 26) is in the locked state, the support (21, 26) can be positioned at the position specified by the positioning stopper. In the example described in FIG. 20, the position specified by the positioning stopper corresponds to a position directly above the central axis of the rod-shaped portion 20.

More specifically, the first divided body (218a, 268a) is provided with an engaging portion EN1 that can be engaged with the positioning stopper. Therefore, the first split body (218a, 268a) cannot move beyond the positioning stopper to the second split body side. In addition, the second split body (218b, 268b) is provided with an engaging portion EN2 that can be engaged with the positioning stopper. Therefore, the second split body (218b, 268b) cannot move beyond the positioning stopper to the side of the first split body. In this way, the first split body (218a, 268a) and the second split body (218b, 268b) come into contact with each other at the position where the positioning stopper is arranged.

Furthermore, the opening and closing operating mechanism M can also use a toggle clamp (model: MC02-S2) manufactured by MISUMI Co., Ltd.

In the example described in FIG. 20, the support tools (21, 26) are opened and closed by swinging operating levers (212a, 262a). According to this, it is possible to easily open and close the supports (21, 26) using a remote operation tool.
