Further, the movable chuck 4 can be connected with the active skeleton by adopting various structures, and some of the movable chucks are arranged by adopting the following structures:
the movable chuck 4 is rotationally connected with the main framework 3 through a connecting shaft 13, and a first spring 14 is arranged at the rotationally connected position; when an external force is applied to rotate the connecting shaft 13, the movable clamp 4 can be moved to increase the distance between the movable clamp 4 and the main clamp 7, so that the movable clamp 4 and the main clamp 7 are in an open state. Meanwhile, due to the arrangement of the first spring 14, the first spring 14 can generate elastic potential energy in the rotation process of the connecting shaft 13; when the external force is removed, the first spring 14 releases elastic potential energy, so that the connecting shaft 13 reversely rotates, the distance between the movable chuck 4 and the main chuck 7 is reduced, and the welding rod 26 is clamped.
Specific: the movable clamping head 4 is fixedly connected with one end of the connecting shaft 13, the connecting shaft 13 is rotationally connected with the main framework 3, and corresponding connecting lugs can be arranged on the main framework 3.
