[0008] The flexible insulating sleeve is sleeved outside the conductive chain body, and the two ends of the flexible insulating sleeve are fixedly connected with the conductive clamps respectively.
[0009] Preferably, the end of the upper clamp and the lower clamp away from the clamp block is a pressing part, and the pressing part is detachably connected with an insulating shell outside.
[0010] Preferably, the inner side of the upper clamp or the inner side of the lower clamp is fixedly connected with a docking foot, and the docking foot is provided with a threaded hole.

[0024] Electrically-conductive chain body 2 is composed of a plurality of sequentially connected chain rings, and the volume and weight of a single chain ring can be as small as possible, so as to facilitate reducing the pulling feeling in the rotating process of electrically-conductive chain body 2. The chain rings at the two ends of electrically-conductive chain body 2 are detachably connected with electrically-conductive clamp 1. As an implementation mode, a docking foot base 11 can be fixedly installed on the inner side of upper clamp 4 or on the inner side of lower clamp 5, the docking foot base 11 is provided with a threaded hole, the chain rings at the two ends of electrically-conductive chain body 2 are respectively fixedly connected with a threaded rod 12, the threaded rod 12 is inserted into the threaded hole, and the threaded rod 12 is threadedly connected with the docking foot base 11.
