A second installation groove 115 is arranged on the second cross frame 111. A second lead screw 114 is rotatably arranged in the second installation groove 115. A second lead nut 116 is arranged on the second lead screw 114. The second lead nut 116 is connected to the second reinforcement plate 103 and can control the movement of the second fixing plate. Specifically, the spiral directions of the first lead screw 108 and the second lead screw 114 are opposite. Then, when the first lead screw 108 and the second lead screw 114 rotate in the same direction, the first reinforcement plate 101 and the second reinforcement plate 103 can be driven to move towards each other.

[0028] First, connect the lead body 2 to the T-shaped wire clamp 4. At the same time, rotate the first lead screw 108 and the second lead screw 114 in the same direction. The first lead nut 110 and the second lead nut 116 move towards each other at the same time.

Through the elastic force of the return spring 64, the fixing pin 63 is in close contact with the lead body 2 and locks the lead body 2, performing multi-stage fixing on the lead body 2 to prevent it from loosening.

[0034] Furthermore, the cross-section of the fixing pin 63 is conical, and an arc surface is provided at the end of the fixing pin 63, which can further improve the firmness of the fixing of the fixing pin 63 to the lead body 2.

[0035] Furthermore, a first insulating pad is arranged on one side of the first reinforcement plate 101, and a second insulating pad is arranged on one side of the second reinforcement plate 103, improving the insulation of the first reinforcement plate 101 and the second reinforcement plate 103.
