When the hydraulic press 2 rotates, the fixed plate 7 is driven to rotate. A tilted workbench 8 is provided above the fixed plate 7. A lifting mechanism is connected between the workbench 8 and the fixed plate 7. By starting the hydraulic press 2, the workbench 8 can be lifted to achieve the purpose of adjusting the height of the workbench 8. The lifting mechanism includes two hinges 18 rotatably connected to the lower end of the lower end of the workbench 8. The other ends of the two hinges 18 are rotatably connected to the upper end of the fixed plate 7. The lower end of the high end of the workbench 8 is rotatably connected to an electric telescopic rod 17 for lifting. By driving the electric telescopic rod 17 drives the high end position of the workbench 8 to rise and fall. Since the low end position of the workbench 8 is limited by the hinge 18, the lifting of the high end of the workbench 8 is converted into a certain angle rotation around the hinge 18, so as to achieve the angle adjustment of the workbench 8. The electric telescopic rod 17 is rotatably connected to the upper end of the fixed plate 7. The electric telescopic rod 17 is located in the middle of the fixed plate 7, and the two hinges 18 are respectively located on both sides of the electric telescopic rod 17. A screw groove 9 is opened on the workbench 8. A double-headed screw 15 is arranged in the screw groove 9. One end of the double-headed screw 15 is rotatably connected to the side wall of the screw groove 9.

The limit plate 14 moves forward or backward to limit accessories of different sizes, and then the double-headed screw 15 is driven to rotate by rotating the first crank 11. The rotation of the double-headed screw 15 drives the two sliders 16 to move closer or farther away from each other, thereby driving the two clamping blocks 10 to clamp or release the accessories. After the accessories are clamped, the high end position of the workbench 8 is driven to rise and fall by starting the electric telescopic rod 17. Since the low end position of the workbench 8 is limited by the hinge 18, the lifting of the high end of the workbench 8 is converted into a rotation at a certain angle around the hinge 18, thereby achieving the angle adjustment of the workbench 8.
