The outer walls of the mounting seat 1 are respectively installed with motors 12 and drive components 13, and the drive components 13 are connected to the annular groove 11. The output end of the motor 12 is fixedly connected to the rotating shaft 2, and the output end of the motor 12 passes through the side wall of the mounting seat 1 and is rotatably connected to the side wall. A mounting plate 5 is installed on the top of the mounting seat 1, and a welding device 6 is installed on the bottom of the mounting plate 5.

[0021] A connecting rod 14 is fixedly installed on the side wall of the adjacent end of the arc-shaped plates 10 at the left and right ends, and a protective cover 9 is fixedly installed on the other end of the connecting rod 14. The protective cover 9 is in close contact with the metal pipe 8. When the arc-shaped plate 10 moves downward, the protective cover 9 is driven by the connecting rod 14 to approach the end of the metal pipe 8. When the arc-shaped plate 10 clamps the metal pipe 8, the protective cover 9 just covers the connection of the metal pipe 8, and the welding slag of the welding device 6 will not splash elsewhere during the welding process.

[0022] The driving assembly 13 includes a second motor 131, a bidirectional threaded rod 132, a first slider 133, a rectangular plate 134, a slide groove 135 and a second slider 136.

Through the interaction of the motor 12, the rotating shaft 2, the telescopic rod 15 and the disc 3 and other components, when the tops of the two groups of metal pipes 8 are welded, the output end of the motor 12 drives one group of metal pipes 8 to rotate through the rope component, and the other group of metal pipes 8 rotates accordingly, which facilitates the welding device 6 to completely weld the two groups of metal pipes 8.
