[0026] A first arc groove 22 is formed on the bottom surface of the clamp plate 16, and a first wear-resistant pad 23 is fixedly connected to the bottom surface of the clamp plate 16 at the position of the first arc groove 22. A second arc groove 14 is formed on the surface of the wire clamp sleeve 13, and a second wear-resistant pad 15 is fixedly connected to the surface of the wire clamp sleeve 13 at the position of the second arc groove 14. Both the first wear-resistant pad 23 and the second wear-resistant pad 15 are made of rubber material.

[0027] Four mounting ears 20 are fixedly connected to the surface of the clamping plate 16, and the four mounting ears 20 are symmetrically arranged in pairs. A limiting block 17 is arranged on the bottom surface of the wire clamp sleeve 13, and a plug rod 18 with a threaded surface is symmetrically fixedly connected to the surface of the limiting block 17. A nut 19 is threadedly sleeved on the surface of the plug rod 18, and the plug rod 18 and the mounting ears 20 are adapted to each other.

[0028] The working principle of this embodiment is as follows: when using this kind of power fittings, first place one of the cables on the second wear-resistant pad 15 provided on the surface of the wire clamp sleeve 13, then clamp the clamp plate 16 in the wire clamp sleeve 13 according to its own shape, and make the first wear-resistant pad 23 on the bottom of the clamp plate 16 contact with the surface of the cable, then pass the plug rod 18 through the wire clamp sleeve 13 and the mounting ear 20 in turn through the limit block 17, and screw the nut 19 on the surface of the plug rod 18, tighten the nut 19, so that the first wear-resistant pad 23 can be close to the surface of the cable, thereby fixing the cable, and then connect the wire clamp sleeve 13 fixed with the cable to the U-shaped seat 11 through the third mounting bolt 12. The U-shaped seat 11 is then installed on the surface of the moving block 6 through the second mounting bolt 10, thereby completing the fixation of one of the cables, and then rotating the bidirectional screw 8. The rotation of the bidirectional screw 8 can then drive the two moving blocks 6 to approach each other (or move away from each other), so that the spacing between the two wire clamps 13 can be adjusted according to the spacing between the two cables. After the adjustment is appropriate, the above steps can be repeated to fix the second cable in the other wire clamp 13. After the two cables are fixed, the entire suspension wire clamp is connected and fixed to the insulating string through the connecting rod 2.
