[0027] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0028] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0029] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0030] like Figures 1 to 4 As shown, this utility model embodiment provides an electrician's pliers for electrical maintenance, which includes an electrician's pliers body 1, an extension assembly, and a reset component. A tangent assembly is provided between the upper parts of the left and right pliers handles of the electrician's pliers body 1, and a suspension assembly is provided on one outer wall of the electrician's pliers body 1. The reset component is located between the left and right pliers handles and below the tangent assembly. The extension assembly includes an extension handle 11 and a locking plate 13. The lower end of the pliers handle is hinged to the extension handle 11. The pliers handle and the extension handle 11 are provided with a through locking groove, and the locking plate is slidably disposed in the locking groove.

[0031] The electrician's pliers for electrical maintenance provided in this embodiment of the utility model have an extension handle hinged to the lower end of the pliers handle. When in use, the locking plate 13 is slid along the locking groove 12 between the pliers handle and the extension handle to fix the extension handle, which extends the length of the pliers handle, thereby enabling it to be inserted into narrow or deep spaces for operation, thus expanding the applicability of the electrician's pliers.

[0032] In one embodiment, there are multiple extension handles 11, with adjacent extension handles hinged together. Each extension handle 11 is provided with a locking groove 12, and the locking grooves on adjacent extension handles are interconnected. A locking plate 13 is provided in one of the adjacent locking grooves. This design, using multiple extension handles, allows for a further extension of the pliers handle length. It is understood that during use, placing the locking plate between adjacent extension handles, spanning the connection point of adjacent extension handles, secures the two extension handles together, allowing each extension handle to be extended to lengthen the pliers handle. Since adjacent extension handles are hinged together, the uppermost extension handle is also hinged to the lower end of the pliers handle. Therefore, when the pliers handle is not needed, the extension handles can be folded together and then folded onto the pliers handle.

[0033] In other embodiments, the number of extended handles 11 can be two, such as... Figure 3 and Figure 4 As shown.

[0034] Specifically, the locking plate 13 is provided with a plurality of anti-slip grooves 14 evenly distributed along its extension direction. These anti-slip grooves 14 increase the friction between the worker's hand and the locking plate 13, facilitating the sliding of the locking plate within the locking grooves. Preferably, the locking grooves are located in the middle of the pliers handle and the middle of the extension handle. When the extension handle is folded, the locking plate can be located in the locking groove of either the pliers handle or the extension handle.

[0035] Further, the wire cutting assembly includes a wire cutting base 2, a wire cutting blade 21, and a wire retaining ring 22. The wire cutting base 2 is fixedly connected to the inner wall of the right handle of the electrician's pliers body, and the wire cutting blade 21 is fixedly connected to the inner wall of the left handle of the electrician's pliers body. The wire retaining rings are arranged opposite each other on the front and rear side walls of the wire cutting base 2. The wire cutting base is provided with a through hole 23 opposite to the center hole of the wire retaining ring. The left end of the wire cutting base is provided with a groove for cooperating with the blade of the wire cutting blade. The groove is perpendicular to and communicates with the through hole. Using this solution, when it is necessary to cut the wire, open the electrician's pliers body 1, insert the wire into the wire retaining ring 22 and the through hole. After the wire moves to a suitable length in the wire retaining ring 22, press the handle of the electrician's pliers body 1 to make the wire cutting blade 21 move closer to the wire cutting base 2 until the blade inserts into the groove to cut the wire. Then, pull the wire out of the wire retaining ring 22. During the above operation, the folded extension handle 11 can be unfolded, such as... Figure 1 As shown, this extends the length of the pliers handle to increase torque and achieve the purpose of saving effort.

[0036] In one specific embodiment, the through hole 23 can be a semi-circular hole.

[0037] Preferably, a silicone ring 6 is provided inside the wire fixing ring. With this design, during use, the wire is inserted into the silicone ring, and the inner wall of the silicone ring 6 contacts the wire, increasing the friction between the wire fixing ring 22 and the wire. This improves the stability of the wire within the wire fixing ring 22, preventing the wire from falling out of the electrician's pliers body 1 during cutting, and improving the accuracy of the cutting position when cutting the wire.

[0038] Furthermore, the suspension assembly includes a hanging rope 3, a limiting ball 31, and a tightening ring 32. Both ends of the hanging rope 3 are fixedly connected to the outer wall of one side of the electrician's pliers body 1. The tightening ring 32 is fitted over the hanging rope 3, and the limiting ball 31 is fixedly connected to the middle of the hanging rope 3. With this design, after using the electrician's pliers, the hanging rope 3 is suspended on the hook of the electrician's bag. Pulling the tightening ring 32 towards the limiting ball 31 prevents the tightening ring 32 from falling off. Thus, the hanging rope 3, the limiting ball 31, and the tightening ring 32 form the suspension assembly for the electrician's pliers, achieving the function of hanging and storing the electrician's pliers after use. This solves the problem of repeatedly taking the electrician's pliers out of the electrician's bag during use and avoids the possibility of the electrician's pliers falling and causing damage due to instability.

[0039] Preferably, the jaws of the electrician's pliers body 1 are provided with multiple stripping holes 4 arranged sequentially from top to bottom, with the diameter of each stripping hole gradually increasing from top to bottom. Using this design, when it is necessary to remove the insulation layer of a wire, the wire is placed in the corresponding stripping hole 4 according to its size, then the handle of the electrician's pliers body 1 is pressed to cut the insulation layer of the wire, and then the insulation layer is peeled off, separating the insulation layer from the conductor. This conveniently achieves the removal of insulation layers from wires of different sizes, improving the adaptability of the electrician's pliers.

[0040] Specifically, the reset component is spring 5. With this design, when the left and right jaw handles are pressed, spring 5 is compressed; when the two jaw handles are released, spring 5 causes the two jaw handles to move away from each other, allowing them to automatically and quickly reset, thus achieving the reset of the jaw handles with relatively little effort. At this time, one end of spring 5 is fixedly connected to the inner wall of the left jaw handle, and the other end of spring is fixedly connected to the inner wall of the right jaw handle.

[0041] This utility model allows the extension handle 11 to be folded or unfolded as needed during use. For example, when using the electrician's pliers in a confined space, the handle of the pliers body 1 can be extended using the extension component to increase the overall length of the pliers. Then, the pliers can be inserted into the confined space to cut the wire using the wire-cutting component. When not in use, the extension handle can be folded up. Figure 2 As shown, restore the electrician's pliers to their initial length, and then use the suspension assembly to suspend the electrician's pliers on the electrician's bag.

[0042] This invention effectively solves the problem of electrician's pliers being inconvenient to operate in narrow spaces, making the overall length of the electrician's pliers adjustable, and making electrical equipment in narrow spaces easier to repair, thus expanding the application scenarios of the electrician's pliers.

[0043] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
