s4, the distance between the adjusting rod (7824) and the workpiece is changed by releasing the engagement between the convex rod (7827) and the groove (7823) through pressing the pressing block (7828), the length of the sleeve rod (7822) and the adjusting rod (7824) is changed when the sleeve rod is contacted with the workpiece, the rotating time of the third gear (785) is also changed, meanwhile, the second clamping block (7864) clamps the workpiece firstly, and the buffering effect is achieved under the elastic force of the second spring (7865).
