Rotating the handle 11 clockwise drives the rotating shaft 54, which drives gear 3 9 through gear 1 8. The linkage gear 2 10 drives the limiter 53 of fixing device 2 6 to rotate synchronously, adjusting the two limiters 53 to the appropriate height and pressing the outer wall of the tube 16. When the two limiters 53 rotate to the pressing position, rotating gear 1 8 can simultaneously drive gear 2 9 to rotate, allowing the limiters 53 of fixing device 1 5 and fixing device 2 6 to move up and down simultaneously. This allows the two limiters 53 to press down on the tube 16 simultaneously, thus ensuring stable fixing. After the weld is completed, rotate handle 11 counterclockwise to release limiter 53, rotate pipe 16 to expose the unwelded weld seam to the welding torch's welding position, and tighten limiter 53. Repeat this process until welding is complete. This way, by simply rotating handle 11, both limiters 53 can be raised and lowered simultaneously, completing the clamping of the pipe fitting in one operation, which is convenient and saves time.
