[0022] The supporting legs 2 stably support the workbench 1. Initially, the hydraulic cylinder 4 is in a retracted state, the distance between the two sets of clamping plates 10 is large, the end of the stamping rod 7 with the clamping groove is inserted into the supporting ring, the handle 13 drives the rotation of the worm 12 in the cover 8, the two sets of worm gears 11 drive the rotation of the two sets of screws, and then the two sets of clamping plates 10 move towards each other, the gap of the clamping plate 10 is inserted into the clamping groove of the stamping rod 7. The workbench 1 provides stable support for the supporting frame 3, and the supporting frame 3 provides stable support for the hydraulic cylinder 4. When it is necessary to replace or repair the stamping rod 7, the handle 13 is rotated to reversely rotate the worm 12. The worm 12 drives the reverse tooth screw 9 to reversely rotate, the two sets of clamping plates 10 move away from each other, the stamping rod 7 is loosened, the stamping rod 7 is pulled out of the supporting pipe 6, and replacement or repair is performed. The new stamping rod 7 is inserted into the supporting pipe 6, the stamping rod 7 is clamped again according to the installation steps, and the stamping operation can be continued.
