The above-mentioned first surface treatment process is currently operated manually with equipment, which is inefficient and the effect after treatment is not high. Summary of the invention

The connecting rods 5 are slidably mounted on the circular mounting seat 2. The surrounding side walls of the circular elastic ring 3 are provided with connecting seats corresponding to the number and position of the connecting rods 5, and the ends of the connecting rods 5 are correspondingly mounted therein; the connecting rods 5 play the role of connecting the circular elastic ring 3 with the circular mounting seat 2 on the one hand, and provide the role of outward expansion guidance when the circular elastic ring 3 expands outward on the other hand; when replacing the circular elastic ring 3, it is only necessary to unscrew and pull out the connecting rods 5. In addition, the inner ring walls on the left and right sides of the loop elastic ring 3 are chamfered structures, which can facilitate the insertion of a copper busbar flexible connection that is larger than the caliber of the loop elastic ring 3 and smaller than the tensile limit size of the loop elastic ring 3.

In this embodiment, four clamping guide columns 19 are provided, which are correspondingly distributed around the clamping lower plate 18, and each clamping guide column 19 corresponds to a clamping nut 21. The stop bar 22 serves to limit the copper busbar soft connection in the right direction.
