[0038] In this embodiment, the wire clamp includes a wire clamp body 7-1, a main wire clamping block 7-3, and a branch wire clamping mechanism. During actual use, after using a stripper to strip the connection section of the main wire 11, the branch wire 10 is clamped on the branch wire clamping mechanism, and the main wire clamping block 7-3 is hooked on the stripped connection section of the main wire 11. By screwing the adjusting nut 7-5, the main wire clamping block 7-3 is driven by the lead screw 7-4 to move, so as to achieve the purpose of clamping the main wire 11, thereby achieving the purpose of connecting the branch wire 10 to the main wire 11 through the wire clamp. It should be noted that during the process of the operator performing live installation of the wire clamp, when the wire clamp is fixed in the first housing 2-1, when the main wire clamping block 7-3 needs to be hooked on the main wire 11, the first housing 2-1 and the second housing 2-2 must be in an open state. After the main wire clamping block 7-3 is hooked on the main wire 11, an insulating tool can be used to make the unfixed second housing 2-2 flip around the hinge shaft 1 to achieve the buckling of the first housing 2-1 and the second housing 2-2.

[0039] In this embodiment, by providing an insulating tool for quickly installing the wire clamp on the main wire 11 or removing the wire clamp from the main wire 11, the insulating tool can be used to perform live installation and disassembly of the wire clamp while standing on the electric pole, which helps to improve the safety of live construction, has good use effect, and is convenient for popularization and application.

A screw rod through hole is provided on the branch clamping block 7-2. The branch clamping block 7-2 is located between the line clamping body 7-1 and the main line clamping block 7-3. A branch clamping channel 8-1 is formed between the branch clamping block 7-2 and the line clamping body 7-1, and a main line clamping channel 8-2 is formed between the main line clamping block 7-3 and the branch clamping block 7-2. The axis of the branch clamping channel 8-1 is parallel to the axis of the main line clamping channel 8-2.

[0041] During actual use, when it is necessary to clamp the branch line 10 on the branch line clamping mechanism, only need to thread the branch line 10 through the branch clamping channel 8-1 and fixedly connect the branch clamping block 7-2 and the line clamping body 7-1 by screwing the connecting bolt 7-7, then the purpose of clamping the branch line 10 in the branch clamping channel 8-1 can be achieved; afterwards, hook the main line clamping block 7-3 on the peeled connecting section of the main line 11, and by screwing the adjusting nut 7-5, drive the main line clamping block 7-3 to move towards the side close to the branch clamping block 7-2 by the screw rod 7-4, so as to clamp the main line 11 in the main line clamping channel 8-2, thereby achieving the purpose of connecting the branch line 10 to the main line 11 through the wire clamp.

The electric wrench 13 drives the sleeve 13-1 to rotate, and the sleeve 13-1 drives the adjusting nut 7-5 to rotate. When the adjusting nut 7-5 drives the lead screw 7-4 to move downward, it can drive the main line clamping block 7-3 to move downward, so as to clamp the main line 11 in the main line clamping channel 8-2 and realize the installation of the wire clamp on the main line 11; when the adjusting nut 7-5 drives the lead screw 7-4 to move upward, it can drive the main line clamping block 7-3 to move upward, and the disassembly of the wire clamp from the main line 11 can be realized.

Then, the clamp is installed on the sleeve 13-1 of the electric wrench 13, and the first housing 2-1 and the second housing 2-2 must be in an open state. After that, the clamp is lifted by the insulating rod 14 and suspended on the stripped connection section of the main line 11 at high altitude. Then, the electric wrench 13 is controlled to start by the remote controller, and the adjusting nut 7-5 is screwed.
