[0044] In the present application, each time the feeding mechanism 5 conveys the cylinder to the clamping mechanism, the opening of the avoidance groove 431 is downward, so that the limit plate 54 can enter and leave the limit groove downward conveniently; after the clamp block 43 clamps the cylinder, the clamp block 43 rotates during the welding process, and after the welding is completed, the clamp block 43 continues to rotate until the first sensor 446 detects the detection block 447 and the motor 443 stops.
