[0044] The control board 33 continues to move, first driving the energy transmission component 41 into the inner side of the energy transmission groove 48, driving the air inside the energy transmission groove 48 to enter the inner side of the connecting cavity 19 along the energy conduction pipe 49, and the air inside the connecting cavity 19 enters the inner side of the pressing pipe 20.

On the one hand, the energy transmission component 41 can further enhance the downward pressure of the pressure plate 65 to ensure the stability of the circular end cover plate during welding. On the other hand, the air inside the transmission control groove 43 enters the inner side of the guide control cavity 44, thereby driving the lifting component 46 to move upward inside the lifting tube 45. The lifting component 46 drives the annular sleeve 25 to move upward through the side frame 16, thereby realizing the separation of the positioning plate 15 from the circular end cover plate.

[0046] The lifting adjustment component 61, together with the fixed frame 60, realizes the lifting of the lifting seat 62.
