[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] The utility model provides Figure 1-6 The multifunctional electrician's pliers shown include a first pliers arm 1 and a second pliers arm 2;

[0030] The groove 3 is provided above the inner side of the first clamp arm 1 and the second clamp arm 2 for stable clamping. The first clamp arm 1 and the second clamp arm 2 are both provided with a wire stripping groove 4. A movable shaft 9 is installed between the first clamp arm 1 and the second clamp arm 2. A force-saving spring 10 is provided between the first clamp arm 1 and the second clamp arm 2.

[0031] The locking assembly 11 is installed inside the first clamp arm 1 and the second clamp arm 2 and is used for locking;

[0032] The adjusting mechanism 12 is installed at the lower ends of the first clamp arm 1 and the second clamp arm 2 and is used for length adjustment. When the first clamp arm 1 and the second clamp arm 2 are combined to clamp the wire, the limiting sleeve 1102 outside the fixed block 1101 on the inner side of the first clamp arm 1 is pushed, so that the limiting sleeve 1102 moves outside the fixed block 1101. When the limiting sleeve 1102 moves upward, the limiting grooves 1104 opened on the upper sides are sleeved on the outside of the limiting blocks 1105 on the inner sides of the first clamp arm 1 and the second clamp arm 2, thereby locking the first clamp arm 1 and the second clamp arm 2.

[0033] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, a hexagonal slot 5 is provided on the surface of one side of the first clamp arm 1, a wiring hole 6 is provided inside one side of the first clamp arm 1, a tool 7 is provided on one side of the second clamp arm 2, and a winding hole 8 is provided inside one side of the second clamp arm 2. The hexagonal slot 5 provided on one side of the first clamp arm 1 can be used to screw the hexagonal screw without carrying a hexagonal plate, which improves convenience. At the same time, the wiring hole 6 inside the first clamp arm 1 can divide the wiring harness into two halves by passing the wiring harness through the wiring hole 6, which is more convenient than manually tearing it apart. The tool 7 provided on one side of the second clamp arm 2 can cut off the surface of the wiring harness. Finally, the winding hole 8 is provided inside one side of the second clamp arm 2. The four groups of wiring harnesses are passed through the winding hole 8, and then the entire electrician's pliers are rotated to wind the four groups of wiring harnesses together, which is more convenient than manual de-winding. These functions further reflect the versatility of the electrician's pliers.

[0034] like Figure 1 and Figure 5 As shown, the locking assembly 11 includes a fixed block 1101, which is installed on one side of the interior of the first clamp arm 1, and the external movably connected to the limiting sleeve 1102, and a sliding groove 1103 is provided on one side surface of the limiting sleeve 1102, and a limiting groove 1104 is provided on the front side surface of the limiting sleeve 1102. A limiting block 1105 is provided on one side of the interior of the first clamp arm 1 and the second clamp arm 2. When the first clamp arm 1 and the second clamp arm 2 are combined to clamp the wire, the limiting sleeve 1102 outside the fixed block 1101 on the inside of the first clamp arm 1 is pushed, so that the limiting sleeve 1102 moves outside the fixed block 1101, and when the limiting sleeve 1102 moves upward, the limiting grooves 1104 on both sides above are set outside the limiting blocks 1105 on the inside of the first clamp arm 1 and the second clamp arm 2, thereby locking the first clamp arm 1 and the second clamp arm 2.

[0035] like Figure 5 As shown, the limiting groove 1104 opened on the front surface of the limiting sleeve 1102 is movably engaged with the limiting block 1105, and the limiting block 1105 is L-shaped. The limiting block 1105 is L-shaped, so that the limiting sleeve 1102 is sleeved on the outside of the two groups of limiting blocks 1105 when sliding, so that the limiting block 1105 is locked between the first clamp arm 1 and the second clamp arm 2 to avoid loosening.

[0036] like Figure 1 and Figure 6As shown, the adjustment mechanism 12 includes a connecting plate 1201, which is installed at the lower ends of the first clamp arm 1 and the second clamp arm 2. The inner surface of the connecting plate 1201 is provided with a threaded groove 1202, and the outer surface of the connecting plate 1201 is provided with a handle 1203. A bolt 1204 passes through the top of the handle 1203. The handle 1203 is moved on the connecting plate 1201 on the side of the first clamp arm 1 and the second clamp arm 2. When it is moved to an appropriate length, the bolt 1204 is passed through the threaded groove 1202 above the handle 1203 and the connecting plate 1201, thereby limiting and fixing the connecting plate 1201 and the handle 1203. This way of adjusting the length is convenient for electrician maintenance personnel to use.

[0037] like Figure 6 As shown, there are two groups of handles 1203. The outer covers of the two groups of handles 1203 are provided with rubber covers 1205. The outer covers of the two groups of handles 1203 are provided with rubber covers 1205. When performing live operations, the rubber covers 1205 provide additional safety protection for electricians and reduce electric shock injuries caused by accidental touch or other unexpected situations.

[0038] The practical working principle of the present invention is as follows: when using the multi-function electrician's pliers, first adjust the length of the multi-function electrician's pliers that the electrician maintenance personnel needs to hold, and move the handle 1203 on the connecting plate 1201 on one side of the first clamp arm 1 and the second clamp arm 2. When it is moved to the appropriate length, the bolt 1204 is passed through the handle 1203 and the threaded groove 1202 above the connecting plate 1201, so as to limit and fix the connecting plate 1201 and the handle 1203. This way of adjusting the length is convenient for the electrician maintenance personnel to use. Later, during maintenance work, when it is necessary to tighten or loosen the hexagonal screw, the hexagonal screw can be screwed through the hexagonal slot 5 opened on the side of the first clamp arm 1, and there is no need to carry a hexagonal plate separately, which improves convenience. At the same time, when it is necessary to tear the wiring harness or wrap multiple sets of wiring harnesses together, the wiring harness can be divided into two halves through the wiring harness passing through the wiring harness hole 6 inside the first clamp arm 1, which is more convenient than manual labor. The first clamp arm 1 and the second clamp arm 2 are kept stable by the locking assembly 11, and can clamp the workpiece or wiring harness more accurately.

[0039] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
