The two nut seats 63 move closer to each other, driving the two sliders 5 and the fixed blocks 71 on the sliders 5 to move, so that the pressure rollers 73 on the fixed blocks 71 clamp the pipe fitting around its perimeter. At the same time, the push cylinder 94 pushes the clamping plate 95 to clamp and fix the end of the pipe fitting; during welding, the rotation motor 96 drives the rotating frame 93 to rotate, thereby driving the pipe fitting to rotate one revolution, so that the operator can weld the pipe fitting once.
