The annular electromagnet 21 is a powerful electromagnet. When the annular electromagnet 21 is energized, the annular electromagnet 21 can adsorb each iron sheet 71, that is, the iron sheet 71 is fixed on the annular electromagnet 21. At this time, the rotation of the movable cylinder 3 is restricted, and during the spiral advancement of the arc-shaped orifice plate, the annular electromagnet 21 is in a de-energized state.

[0043] During the movement of the stepped shaft 2, the first piston head 121 squeezes the air flow in the matching hole 22 and discharges it from the air guide channel, thereby accelerating the heat dissipation at the welding position and avoiding excessive temperature when welding at the next position, which helps to reduce welding defects and improve the welding quality; after the welding is completed, the first hydraulic cylinder 111 drives the stepped shaft 2 to reset, and the second hydraulic cylinder 621 drives the moving seat 61 to reset, at which time it is convenient to take out the cylinder formed by the welding; in addition, during welding, the arc-shaped orifice plate spirally advances and contacts the universal ball 631, and due to the provision of the long hole 44 and the guide channel 411, air can be sucked into the matching hole 22.
