The output end of the first motor is fixedly connected to the rotating rod 6. The toothed synchronous drive can cause the two first contact rollers 4 to rotate synchronously, driving the stiffening ring to rotate and adjust.

[0025] Specifically, when the stiffening ring needs to be welded, the stiffening ring is placed above the two sliding plates 2, and the first contact roller 4 contacts the outer side of the stiffening ring to support and fix the stiffening ring. When the welding position of the stiffening ring needs to be adjusted, the first motor on the outer side of the four support plates 3 is started, so that the first motor drives the rotating rod 6 to rotate, and the toothed synchronous wheel 5 and the toothed synchronous belt on the outer side of the rotating rod 6 are used for transmission, so that the first contact roller 4 drives the stiffening ring to rotate, thereby adjusting the welding position.

[0026] Please refer to Figures 1, 2 and 4 again.
