In practical application, when the fourth motor 21 operates, the screw 17 is driven to rotate, the screw nut 18 and the nut seat 19 are driven to move forward or backward on the screw 17 along the extending direction of the screw 17, so as to drive the synchronous rod 13 to move forward or backward correspondingly, and therefore the follow-up support mechanism 10 connected with the other end of the synchronous rod 13 is enabled to ascend or descend in the lathe bed 1 to adapt to the rotation and cutting of the reducer union. Specifically, the fourth motor 21 is a servo motor, and when the fourth motor 21 operates in the reverse direction, the moving directions of the sliding table transmission mechanism, the first synchronizing rod connecting block 22, the synchronizing rod 13 and the fourth motor 21 during the forward operation are opposite, so as to drive the servo support mechanism 10 to ascend or descend (if the fourth motor 21 operates in the forward direction, the servo support mechanism 10 ascends, the fourth motor 21 operates in the reverse direction, and the servo support mechanism 10 descends, otherwise, when the fourth motor 21 operates in the forward direction, the servo support mechanism 10 descends, and the servo support mechanism 10 ascends, the fourth motor 21 operates in the reverse direction).

The smoothness of the ascending or descending of the first elevation plate 26 is improved by providing the second elevation rail 40 and the second elevation slider 41.
Further, the side walls of the two ends of the second lifting track 40 are both provided with a fourth limiting block 42. Similarly, the fourth stopper 42 also protects the second lifting slider 41.
