A second hydraulic cylinder 17 is arranged on one side of the moving block 4. The output shaft of the second hydraulic cylinder 17 is connected to the installation ear 16, which can move the clamped workpiece forward and backward and left and right. It is relatively perfect. A guide rod 6 that is slidably connected to the moving block 4 is fixed between the outer walls of the two fixed ears 2, making the movement of the first mounting plate 5 on the moving block 4 relatively stable and facilitating driving one of the workpieces to move forward and backward; The rotating component includes a support shaft 7 rotatably installed on the other side of the top of the bottom plate 1. A second mounting plate 12 is fixed on the top of the support shaft 7. A worm gear 8 is fixed on the outer wall of the support shaft 7.
