[0024] Please refer to Figures 1-5In this embodiment, the clamping piece 10 is designed with an arc-shaped structure. The upper end of the shock-absorbing pad 11 is fixedly connected to the lower end of the clamping piece 10. The lower end of the shock-absorbing pad 11 and the upper end of the welding gun body 2 are adapted to each other. The shock-absorbing pad 11 is made of rubber. There are two fixing plates 12 symmetrically arranged in front and back, and they are integrally formed with the clamping piece 10. Fixing holes 121 are opened at equal intervals on the surface of the fixing plate 12, and bolt holes are opened at equal intervals on the upper end of the limiting seat 13.
