[0077] A transmission gear 14 is provided at the bottom of the threaded adjustment rod 3, which meshes with the driving gear 13 of the eccentric wheel reduction motor 2.

[0078] When the eccentric wheel reduction motor 2 rotates, it drives the transmission gear 14 to rotate through the driving gear 13, and then rotates the threaded adjustment rod 3.

[0079] Linkage between the ejection locking plate 5 and the swing connecting rod 4:

[0080] Working principle:

[0081] The bottom of the ejection locking plate 5 is hinged with a swing connecting rod 4, and the swing connecting rod 4 is sleeved on the threaded adjustment rod 3 through a threaded structure.

[0098] When performing the pipe shrinking and roundness correction work on the pipe fitting, the first hydraulic rod 10 and the second hydraulic rod 11 can play a certain buffer and rebound role. The buffer and rebound absorb the impact force generated during the pipe shrinking and roundness correction process, reduce the vibration of the equipment, help improve the processing accuracy and stability, and avoid the processing errors caused by vibration.
