The welding gun 50 is detachably mounted on the operating table 10.

[0019] In this embodiment, the operating table 10 is configured as a rectangular parallelepiped structure.

[0020] Through the arrangement of the carrier 20, the clamping member 30, the limiting rod 40 and the welding gun 50, the clamping member 30 includes a first clamping portion 31, a second clamping portion 32 and a locking buckle 33. The curled edge to be processed is placed on the carrier 20, and the two ends of the curled edge are inserted into the clamping areas of the first clamping portion 31 and the second clamping portion 32. The locking buckle 33 clamps and fixes the curled edge in the clamping areas inside the first clamping portion 31 and the second clamping portion 32. The limiting rod 40 is installed on the operating table 10. The limiting rod 40 fixes the peripheral wall of the curled edge to be processed, and then the end of the curled edge is welded by the welding gun 50, which improves the welding efficiency of the curled edge, improves the stability of the welding of the end of the curled edge, and ensures the quality of the curled edge welding.

[0021] In this embodiment, the support member 20 is configured as a cylindrical structure. A connecting block is installed at the bottom of the operating table 10 .
