Description

Technical Field

[0001] The present invention relates to an electric wire tool and an electric wire work method.

Background Art

[0002] For example, Patent Document 1 describes a cutting auxiliary tool for high-voltage drop wires that is used during cutting and reconnection of electric wires. The cutting auxiliary tool for high-voltage drop wires includes a tubular body having a first tubular body and a second tubular body slidable relative to the first tubular body, a first clip provided on the first tubular body to grip the drop wire, and a second clip provided on the second tubular body to grip the drop wire. Such a cutting auxiliary tool for high-voltage drop wires is used as follows. First, with the tubular body in a contracted state, the high-voltage drop wire is gripped by the first and second clips. Next, the high-voltage drop wire is cut between the two positions gripped by the first and second clips. Then, the tubular body naturally extends to a predetermined length under its own weight. Thereby, the ends of the high-voltage drop wire are separated from each other.

Summary of Invention

Problems to be Solved by the Invention

[0004] However, the cutting auxiliary tool for high-voltage drop wires of Patent Document 1 requires the tubular body to be contracted in advance before use, and the length of the tubular body at the time of extension must be predetermined, resulting in poor usability. In addition, since the tubular body can only extend and contract, the degree of freedom of deformation during use is low, which also leads to poor usability.

[0005] An object of the present invention, which was made in view of the above problems, is to provide an electric wire tool and an electric wire work method that are excellent in operability.

[0013] (7) Long wires and The wire material is arranged in a first holding part that holds the electric wire, The wire has a second holding portion that is spaced apart from the first holding portion and holds the electric wire, The wire material undergoes elastic deformation and expansion / contraction in at least a portion of the area between the first holding portion and the second holding portion, and when using a wire tool that cannot maintain the relative positional relationship between the first holding portion and the second holding portion, A mounting step of attaching the first holding part and the second holding part to the electric wire while the wire is bent, A method for working with electric wires, characterized by comprising a cutting step of cutting the electric wire at a location between the first holding portion and the second holding portion.

[Effects of the Invention]

[0016] According to the wire tool of the present invention, the wire is configured to be elastically deformable and expandable in at least a portion of the area between the first and second holding parts. Furthermore, the wire is configured not to maintain its relative positional relationship with the first and second holding parts. Therefore, the relative positional freedom of the first and second holding parts is high. In other words, within the expandable range of the wire, the position and orientation of one of the first and second holding parts can be changed freely with substantially no restriction on the other. Therefore, it becomes a wire tool with excellent operability.

[0017] In addition, due to high operability, it is possible to appropriately cope with various different situations at each work site, so that the electric wire tool can be used reasonably and appropriately, and the relevant work can also be performed safely. Furthermore, since the first holding portion and the second holding portion are arranged on the electric wire in a state where the wire rod is bent, at the same time as the electric wire is cut between the first holding portion and the second holding portion, at least one of the first holding portion and the second holding portion falls until the wire rod is pulled taut, whereby the cut end portions are separated from each other without external intervention. Therefore, smooth work is enabled.

[0018] Further, according to the electric wire work method of the present invention, since the above-described electric wire tool is used, high safety can be exhibited. [Brief Description of the Drawings]

[Modes for carrying out the invention]

[0020] The following will describe in detail embodiments of the wire tool and wire work method of the present invention. For the sake of clarity, the illustration of the wire tool has been simplified in all figures except Figures 5, 9, and 10.

[0021] The wire tool 1 shown in Figure 1 is a tool used during wire work, for example, when cutting or connecting a high-voltage down wire 94 that connects a high-voltage overhead distribution line 92, which is installed on a utility pole 91, to a pole-mounted transformer 93 installed on the utility pole 91. As shown in Figure 2, the wire tool 1 has a long wire 2 and a first holding part 3A and a second holding part 3B provided at both ends of the wire 2. These parts will be described in order below.

[0022] First, let's describe the wire 2. The wire 2 is elastic throughout and can expand and contract in the longitudinal direction. Also, because the wire 2 is sufficiently soft and bends freely, it cannot support the weight of the first holding part 3A and the second holding part 3B, and therefore cannot maintain the relative positional relationship between the first holding part 3A and the second holding part 3B. In other words, when the user holds only the wire 2, the first and second holding parts 3A and 3B both sag downwards in the vertical direction.

[0023] The wire 2 is made of an elastomer or rubber material. By using such a material, an expandable wire 2 can be easily obtained. The elastomer is not particularly limited and includes various thermoplastic elastomers such as styrene-based, polyolefin-based, polyvinyl chloride-based, polyurethane-based, polyester-based, polyamide-based, polybutadiene-based, trans-polyisoprene-based, fluororubber-based, and chlorinated polyethylene-based elastomers. The rubber material is not particularly limited and includes natural rubber, isoprene rubber, butadiene rubber, styrene-butadiene rubber, nitrile rubber, chloroprene rubber, butyl rubber, acrylic rubber, ethylene-propylene rubber, hydrin rubber, urethane rubber, silicone rubber, fluororubber, etc. (especially vulcanized rubber).

[0024] In particular, the wire 2 in this embodiment is made of urethane rubber. This results in a wire 2 with appropriate softness and elasticity (stretchability), improving the operability and safety of the wire tool 1. However, the constituent material of the wire 2 is not particularly limited as long as it is elastic and stretchable.

[0025] Furthermore, as shown in Figure 3, the wire 2 is tubular. By making the wire 2 tubular, its strength and rigidity can be moderately increased. This improves the operability and safety of the wire tool 1. However, the shape of the wire 2 is not particularly limited; for example, it may be a solid tube, a string, or a chain made up of multiple interconnected rings.

[0026] Although the wire 2 has been described above, the wire 2 is not particularly limited as long as it is elastic and expandable in at least a portion of the region between the first holding portion 3A and the second holding portion 3B. For example, as shown in Figure 4, the wire 2 may have a configuration comprising a pair of rigid first portions 2A provided at both ends that are substantially indeformable, and a second portion 2B located between the pair of first portions 2A that is elastic and expandable. Alternatively, a configuration in which multiple such first portions 2A and second portions 2B are arranged alternately may also be used.

[0027] Next, the first holding part 3A and the second holding part 3B will be described. As shown in Figure 2, the first holding part 3A is provided at one end of the wire 2, and the second holding part 3B is provided at the other end of the wire 2. By arranging the first holding part 3A and the second holding part 3B at both ends of the wire 2 in this way, it is possible to keep the overall length of the wire 2 short while ensuring a large distance between the first holding part 3A and the second holding part 3B. In addition, the protrusion of the wire 2 beyond the first and second holding parts 3A and 3B is suppressed. As a result, the wire tool 1 is compact and has high operability and safety.

[0028] Furthermore, as shown in Figure 2, the distance D between the first holding part 3A and the second holding part 3B when the wire 2 is straightened without being stretched or compressed is not particularly limited, but is preferably, for example, 30 cm or more and 50 cm or less, and more preferably 30 cm or more and 40 cm or less. By setting the distance between the first holding part 3A and the second holding part 3B to a length suitable for wire work, the operability and safety of the wire tool 1 are improved.

[0029] The first retaining portion 3A and the second retaining portion 3B have the same configuration except for the presence or absence of the engaging portion 39, which will be described later. Therefore, in the following description, the first and second retaining portions 3A and 3B will be collectively referred to as "retaining portion 3".

[0030] As shown in Figure 5, the holding part 3 is a clip that holds the electric wire. By making the holding part 3 a clip, the electric wire can be easily held during work. This improves the operability and safety of the electric wire tool 1. The holding part 3 also has a base part 31 fixed to the end of the wire 2, a clip body 32, and a shaft part 33 connecting the base part 31 and the clip body 32. Such a holding part 3 is mainly made of insulating material such as various resin materials. This improves the safety of the electric wire tool 1.

[0031] The base portion 31 is cylindrical and is fixed to the wire 2, for example, by clamping the wire 2. The base portion 31 also has an insertion hole 311 that opens on its outer end face. The tip of the shaft portion 33 is inserted into the insertion hole 311. Although not shown, the shaft portion 33 is fixed to the base portion 31 by a bolt or the like. The shaft portion 33 has a cylindrical body 331 and an annular flange portion 332 that protrudes radially from the body 331, with the tip of the body 331 being inserted into the insertion hole 311. The body 331 is arranged coaxially (concentrically) with the base portion 31, and its outer diameter is smaller than the outer diameter of the base portion 31. The clip body 32 is held between the base portion 31 and the flange portion 332. This prevents the clip body 32 from shifting (displacement) or coming off.

[0032] As shown in Figures 6 to 8, the clip body 32 has a pair of retaining arms 34 and 35 that open and close by rotating in opposite directions around the pivot axis J, and a torsion spring 36 that biases the retaining arms 34 and 35 in the closing direction.

[0033] The holding arm 34 has an action portion 341 located towards the tip of the pivot axis J, an operating portion 342 located towards the base of the pivot axis J, and a pair of connecting portions 343 and 344 located between the action portion 341 and the operating portion 342 and spaced apart in the direction along the pivot axis J. The connecting portions 343 and 344 also have through holes 343a and 344a.

[0034] The retaining arm 35 has the same configuration as the retaining arm 34. The retaining arm 35 has an action part 351 located on the tip side of the pivot axis J, an operating part 352 located on the base side of the pivot axis J, and a pair of connecting parts 353 and 354 located between the action part 351 and the operating part 352 and spaced apart in the direction along the pivot axis J. In addition, insertion holes 353a and 354a are formed in the connecting parts 353 and 354.

[0035] The main body 331 of the shaft portion 33 is inserted through these insertion holes 343a, 344a, 353a, and 354a. As a result, the clip body 32 is connected to the base portion 31 via the shaft portion 33 and held between the base portion 31 and the flange portion 332. When the clip body 32 is connected to the base portion 31, the pivot axis J of the clip body 32 coincides with the central axis of the shaft portion 33 (base portion 31). Therefore, the feel of operating the clip body 32 is enhanced. In addition, the clip body 32 is rotatable relative to the shaft portion 33 (base portion 31). Therefore, the position of the clip body 32 relative to the base portion 31 can be freely adjusted.

[0036] As shown in Figure 8, two torsion springs 36 are arranged between the connecting portions 344 and 354. The torsion spring 36 has a coil 361, an arm 362 extending from one end of the coil 361, and an arm 363 extending from the other end of the coil 361. The torsion spring 36 is fixed by inserting the main body 331 of the shaft portion 33 through the coil 361. The torsion spring 36 is positioned between the retaining arms 34 and 35 in a compressed state (with the coil 361 wound up), with one arm 362 in contact with the operating portion 342 of the retaining arm 34, and the other arm 363 in contact with the operating portion 352 of the retaining arm 35. Therefore, the elasticity (restoring force) of the torsion spring 36 biases the retaining arms 34 and 35 in the closing direction.

[0037] Furthermore, the inner surfaces (the surfaces that come into contact with the electric wire) of the working parts 341 and 351 are each provided with anti-slip surfaces 37 made of rubber material. By providing the anti-slip surfaces 37, the frictional resistance with the electric wire is increased, and the electric wire can be effectively prevented from slipping. As a result, the electric wire can be held more securely.

[0038] Furthermore, each anti-slip device 37 has a first recess 371 for holding relatively thick wires such as high-voltage overhead distribution lines 92 (for example, wires with a diameter of about 30 mm to 40 mm), and a second recess 372 for holding relatively thin wires such as high-voltage down lines 94 (for example, wires with a diameter of about 5 mm to 25 mm). The first recess 371 is located closer to the tip than the second recess 372 and is larger than the second recess 372. By having such first and second recesses 371 and 372, the holding part 3 can be securely and stably attached to wires of various thicknesses.

[0039] Furthermore, each anti-slip surface 37 is located on the base end side of the second recess 372 and has a restricting projection 373 to prevent the wire from entering beyond the second recess 372. This makes it easier to hold the wire in the second recess 372. The restricting projection 373 also comes into contact with the wire held in the second recess 372. As a result, the frictional resistance between the anti-slip surface 37 and the wire increases, making the wire less likely to slip.

[0040] In this type of holding unit 3, the wire can be held by pinching the operating parts 342 and 352, opening the working parts 341 and 351 against the elasticity of the torsion spring 36, inserting the wire between the working parts 341 and 351, and then closing the working parts 341 and 351 to clamp the wire. In particular, since the pivot axis J of the clip body 32 coincides with the central axis of the base 31, it is easy to grasp the feel of the operation, improving the operability of the holding unit 3.

[0041] The common parts of the first retaining part 3A and the second retaining part 3B have been described above. Next, the differences between the first retaining part 3A and the second retaining part 3B will be described. As shown in Figure 9, the first retaining part 3A further has an engaging part 39 into which the second retaining part 3B engages. By engaging the second retaining part 3B with the engaging part 39, the first retaining part 3A and the second retaining part 3B can be connected. The engaging part 39 is located outside the shaft part 33, is a circular rod shape extending parallel to the shaft part 33, and is connected and fixed to the shaft part 33 at its base end. Also, the central axis of the engaging part 39 is offset from the central axis of the shaft part 33. Then, as shown in Figure 10, by holding the engaging part 39 with the clip body 32 of the second retaining part 3B, the second retaining part 3B engages with the engaging part 39, and the second retaining part 3B is connected to the first retaining part 3A. Furthermore, by shifting the central axis of the engaging portion 39 from the central axis of the shaft portion 33, the clip body 32 can be rotated relative to the shaft portion 33, thereby changing the relative position of the first holding portion 32A and the second holding portion 32B when they are connected, allowing for an appropriate relative position depending on the work. This enables smoother operation.

[0042] The outer diameter of the engaging portion 39 is not particularly limited, but it is preferably about the same as the thickness of the wire intended to be held by the first and second holding portions 3A and 3B, specifically about 5 mm to 40 mm. This allows the engaging portion 39 to be held appropriately in the same way as the wire. Therefore, unintended detachment of the second holding portion 3B from the engaging portion 39 can be effectively prevented, improving the operability of the wire tool 1.

[0043] However, the engaging portion 39 is not particularly limited as long as it can engage with the second holding portion 3B. For example, the central axis of the engaging portion 39 may coincide with the central axis of the shaft portion 33. Also, the engaging portion 39 may not be rod-shaped, but plate-shaped, mesh-shaped, etc. Furthermore, the engaging portion 39 is not limited to being held by the clip body 32 of the second holding portion 3B. For example, it may be configured to hook and hold the second holding portion 3B with a hook or the like, or to attach and hold the second holding portion 3B with an adhesive material or the like. Also, the engaging portion 39 may be integrally formed with the shaft portion 33.

[0044] The first and second holding parts 3A and 3B have been described above, but the configuration of the first and second holding parts 3A and 3B is not particularly limited. For example, the clip body 32 does not need to be able to rotate relative to the shaft part 33. Also, the second holding part 3B may also have an engaging part 39. In other words, both the first and second holding parts 3A and 3B may have an engaging part 39.

[0045] The configuration of the wire tool 1 has been described above. In this wire tool 1, the wire 2 is elastic and can be freely expanded, contracted, and deformed without substantial restrictions, resulting in a high degree of relative positional freedom for the first holding part 3A and the second holding part 3B. In other words, within the expandable range of the wire 2, the position and orientation of one of the first holding part 3A and the second holding part 3B can be freely changed with virtually no restriction relative to the other. Therefore, the wire tool 1 is highly maneuverable. Furthermore, this high level of maneuverability allows for appropriate adaptation to various situations that differ from one work site to another, enabling the wire tool 1 to be used smoothly and appropriately, and the work to be performed safely.

[0046] Next, a method for working with electric wires using the electric wire tool 1 will be described. As shown in Figure 11, the method for working with electric wires using the electric wire tool 1 includes an attachment step S1 in which the electric wire tool 1 is attached to the electric wire, a cutting step S2 in which the electric wire is cut between the first and second holding parts 3A and 3B, a reattachment step S3 in which one of the first and second holding parts 3A and 3B is reattached to another location on the electric wire, a connection step S4 in which the cut parts of the electric wire are connected, and a removal step S5 in which the electric wire tool 1 is removed from the electric wire.

[0047] In the mounting process S1, first, as shown in Figure 10, the clip body 32 of the second retaining part 3B holds the engaging part 39, and the second retaining part 3B is connected to the first retaining part 3A.

[0048] Next, as shown in Figure 12, the first holding part 3A is attached to the high-voltage down wire 94. That is, the clip body 32 of the first holding part 3A holds the high-voltage down wire 94. At this time, by holding the high-voltage down wire 94 with the second recess 372, the high-voltage down wire 94 can be held more stably. Prior to attaching the first holding part 3A to the high-voltage down wire 94, the second holding part 3B was connected to the first holding part 3A in advance. This prevents the second holding part 3B from sagging and swaying when attaching the first holding part 3A to the high-voltage down wire 94, allowing this process to be carried out smoothly.

[0049] Next, as shown in Figure 13, the second holding part 3B is removed from the engaging part 39, and the removed second holding part 3B is attached to the high-voltage down wire 94. In other words, the clip body 32 of the second holding part 3B holds the high-voltage down wire 94. At this time, the second holding part 3B is attached to a location spaced apart in the direction of extension of the high-voltage down wire 94 from the location where the first holding part 3A is attached (in Figure 13, the location on the pole-mounted transformer 93 side), and the wire 2 is bent. With this, the attachment of the wire tool 1 to the high-voltage down wire 94 is completed. Although not shown, the attachment of the wire tool 1 to the high-voltage down wire 94 can be done using, for example, a long tool for working at heights called a "pliers".

[0050] The mounting locations of the first and second holding parts 3A and 3B in mounting step S1 are not particularly limited. For example, as shown in Figure 14, the first holding part 3A may be mounted on the high-voltage overhead distribution line 92. In this case, the high-voltage overhead distribution line 92 can be held more stably by gripping it with the first recess 371. Also, as shown in Figure 15, the first holding part 3A may be mounted on both the high-voltage overhead distribution line 92 and the high-voltage down line 94. In this case, the high-voltage overhead distribution line 92 can be gripped with the first recess 371 and the high-voltage down line 94 can be held more stably by gripping the high-voltage overhead distribution line 92 with the first recess 371 and the high-voltage down line 94 with the second recess 372. Furthermore, the positions of the first and second holding parts 3A and 3B may be reversed compared to this embodiment.

[0051] In cutting step S2, the high-voltage down wire 94 is cut between the first holding part 3A and the second holding part 3B. At the same time as the cut, the cut end 94b held by the second holding part 3B falls along with the second holding part 3B, and as shown in Figure 16, both cut ends 94a and 94b separate. Furthermore, the wire 2, which was bent before cutting, becomes taut when the second holding part 3B falls, preventing the second holding part 3B from falling any further. This prevents excessive displacement of the cut end 94b immediately after cutting (movement beyond the operator's expectations). Therefore, safety of the work is increased. In addition, since the cut ends 94a and 94b separate automatically at the same time as the cut, the effort required to separate the cut ends 94a and 94b is eliminated, allowing for smoother work.

[0052] Next, as shown in Figure 17, an insulating terminal cover 95 is attached to the cut end 94a. Note that since the cut end 94b is on the power outage side, it is not necessary to attach a terminal cover 95 to it.

[0053] In the reattachment process S3, first, the first holding part 3A is removed from the high-voltage down wire 94, and as shown in Figure 18, the first holding part 3A is reattached to the pole-mounted transformer 93 side of the high-voltage down wire 94 from its current location so that the cut ends 94a and 94b are further separated. In other words, the first holding part 3A holds the high-voltage down wire 94 in place on the pole-mounted transformer 93 side. By reattaching the first holding part 3A to the pole-mounted transformer 93 side of the high-voltage down wire 94 in this way, phase confirmation can be easily performed. At this time, by extending the wire 2, the second holding part 3B becomes more stable, and the shaking of the cut end 94b can be prevented more effectively. Then, predetermined work (for example, maintenance of the pole-mounted transformer 93) is performed in this state. Because the cut ends 94a and 94b can be sufficiently separated by this reattachment process S3, the work can be performed more safely.

[0054] In connection step S4, first, the terminal cover 95 is removed from the cut end 94a, and the cut ends 94a and 94b are stripped. Next, as shown in Figure 19, a tubular sleeve 96 is attached to the cut end 94b as a connecting member, and the sleeve 96 is crimped and attached to the cut end 94b. By attaching the sleeve 96 to the connection end 94b on the power outage side in this way, the work can be performed safely.

[0055] Next, the first holding part 3A is removed from the high-voltage down wire 94, and as shown in Figure 20, the first holding part 3A is reattached to the high-voltage overhead distribution line 92, so that the cut ends 94a and 94b are placed side by side (positioned side by side). In this state, the wire 2 is pulled taut by the weight of the second holding part 3B.

[0056] The location where the first retaining part 3A is reattached is not particularly limited, and may be, for example, on the cut end 94a side of the high-voltage down wire 94. By reattaching the first retaining part 3A on the cut end 94a side of the high-voltage down wire 94, which is the connection partner of the cut end 94b, it is possible to prevent short circuits, ground faults, etc., caused by incorrect connections (connection to the wrong partner).

[0057] Next, as shown in Figure 21, the cut end 94b is held with a tool or the like, and the wire 2 is pulled to extend it, causing the cut end 94b to retract so that the cut ends 94a and 94b face each other. Then, as shown in Figure 22, the cut end 94b is brought close to the cut end 94a, the sleeve 96 is inserted into the cut end 94a, and then the sleeve 96 is crimped and fixed to the cut end 94a. In this way, the cut ends 94a and 94b are connected by the sleeve 96. When inserting the sleeve 96 into the cut end 94a, the elasticity of the wire 2 acts as a force (an assisting force for insertion) in the direction in which the sleeve 96 is inserted into the cut end 94a, so the work can be performed more smoothly.

[0058] In removal step S5, the sleeve 96 is covered with an insulating cover, and then the wire tool 1 is removed from the high-voltage overhead distribution line 92 and the high-voltage down line 94. This completes the wire work.

[0059] This method of handling electrical wires allows for the use of an electrical wire tool 1 that offers excellent operability and safety, thus ensuring high safety. When storing the electrical wire tool 1, for example, as shown in Figure 10, the second holding part 3B can be connected to the engaging part 39, and the wires 2 can be bundled together for compact storage.

[0060] The above describes the wire tool 1 and the wire work method using the wire tool 1. As mentioned above, the wire tool 1 is a wire tool used when cutting or connecting electric wires, especially high-voltage down wires 94, and comprises a long wire 2, a first holding part 3A positioned on the wire 2 to hold the electric wire, and a second holding part 3B positioned on the wire 2 spaced apart from the first holding part 3A to hold the electric wire. Furthermore, the wire 2 elastically deforms and expands and contracts in at least a portion of the area between the first holding part 3A and the second holding part 3B, and cannot maintain the relative positional relationship between the first holding part 3A and the second holding part 3B. The first holding part 3A and the second holding part 3B are attached to the electric wire while the wire 2 is bent. With this configuration, the relative positional freedom of the first holding part 3A and the second holding part 3B is increased. As a result, the wire tool 1 has excellent operability. Furthermore, its high operability allows it to appropriately handle various situations that differ from one work site to another, enabling the wire tool 1 to be used smoothly and appropriately, and the work to be performed safely. In addition, since the first holding part 3A and the second holding part 3B are positioned on the wire (high-voltage down wire 94 in this embodiment) with the wire 2 bent, when the high-voltage down wire 94 is cut between the first and second holding parts 3A and 3B, at least one of the first and second holding parts 3A and 3B (the second holding part 3B in this embodiment) falls until the wire 2 is taut, causing the cut ends 94a and 94b to separate on their own. This enables smooth operation.

[0061] Furthermore, as mentioned above, the wire 2 is made of an elastomer or rubber material. With such a configuration, an expandable and contractible wire 2 can be easily obtained.

[0062] Furthermore, as mentioned above, the wire 2 is tubular. This configuration allows for a moderate increase in the strength and rigidity of the wire 2. As a result, the operability and safety of the wire handling tool 1 are improved.

[0063] Furthermore, as mentioned above, the first holding part 3A and the second holding part 3B are clips for gripping electric wires. With this configuration, electric wires can be held easily and accurately during work. As a result, the operability and safety of the electric wire tool 1 are improved.

[0064] Furthermore, as mentioned above, the distance between the first holding part 3A and the second holding part 3B is 30 cm or more and 50 cm or less. With this configuration, the distance between the first holding part 3A and the second holding part 3B becomes a length suitable for electrical wire work, improving the operability of the electrical wire tool 1.

[0065] Furthermore, as mentioned above, the first holding portion 3A has an engaging portion 39 into which the second holding portion 3B engages. With this configuration, by engaging the second holding portion 3B with the engaging portion 39, the second holding portion 3B is less likely to get in the way during work, allowing the work to be performed smoothly and safely. In addition, by engaging the second holding portion 3B with the engaging portion 39, the wire tool 1 can be stored compactly.

[0066] Furthermore, as mentioned above, the wire work method comprises a long wire 2, a first holding part 3A positioned on the wire 2 to hold the wire, and a second holding part 3B positioned on the wire 2 spaced apart from the first holding part 3A to hold the wire, wherein the wire 2 is elastic and expandable in at least a portion of the area between the first holding part 3A and the second holding part 3B, and the wire tool 1, which cannot maintain the relative positional relationship between the first holding part 3A and the second holding part 3B, is used to attach the first holding part 3A and the second holding part 3B to the wire while the wire 2 is bent, and the method comprises an attachment step S1 and a cutting step S2.

[0067] Furthermore, as mentioned above, the process includes a reattachment step S3 performed after the cutting step S2, in which the first retaining part 3A or the second retaining part 3B is reattached to another location. This method allows the cut ends 94a and 94b to be sufficiently spaced apart, thereby increasing safety during the work.

[0068] Furthermore, as mentioned above, the method includes a connection step S4 performed after the cutting step S2, in which the cut ends of the electric wire are connected. The connection step S4 includes the steps of: reattaching the first holding part 3A or the second holding part 3B (first holding part 3A in this embodiment) to another location so that the two cut ends 94a and 94b formed by the cutting are positioned side by side; extending the wire 2 and facing the two cut ends 94a and 94b directly; and bringing the two cut ends 94a and 94b closer together and connecting them using a sleeve 96, which is a connecting member. With this method, in the step of connecting the two cut ends 94a and 94b, the elasticity of the wire 2 generates a force that assists in connecting the cut ends 94a and 94b, so that the work can be performed smoothly.

[0069] The wire tool and wire work method of the present invention have been described above based on the illustrated embodiments. However, the present invention is not limited thereto, and the configuration of each part can be replaced with any configuration or process having a similar function. Furthermore, any other configuration or process may be added to the present invention.

[0070] Furthermore, although the above-described embodiment described an example of cutting a high-voltage down wire 94, the wire to be cut is not particularly limited and may be, for example, a high-voltage overhead distribution line, a low-voltage overhead distribution line, or a service drop to each building. Also, the mounting location of the wire cutting tool 1 can be appropriately changed depending on the type and location of the wire to be cut. [Explanation of Symbols]
