Specifically, the support base 1 is a circular cylinder with three ball joint nodes 11 at one end. The three support legs 81 are connected to each ball joint node 11.

[0046] In order to improve the application range of the welding equipment of this embodiment, in this embodiment, each support leg 81 is a telescopic rod.
