[0022] A circular hole connected to the screw placement hole in the fixture 10 is opened on the top surface of the workbench 1. An L-shaped plate 18 is provided in the workbench 1. A lifting component for lifting the screw is provided on the L-shaped plate 18. By using the lifting component, it is convenient to lift the processed screws, thereby facilitating the removal of the screws. The operation is simple and convenient, which improves the work efficiency of screw cutting.

[0023] In the utility model, the lifting assembly includes a push rod 15 slidably arranged in a circular hole, a circular plate 16 arranged at the bottom of the push rod 15 and a shell 5 arranged on the outer wall of the U-shaped frame 2. A plurality of pulleys 14 are rotatably arranged in the shell 5 and on the inner bottom surface of the L-shaped plate 18. A traction rope 6 is arranged on the bottom surface of the circular plate 16, and the traction rope 6 passes through each pulley 14 and is fixedly connected to the top surface of the mounting plate 3. A reset spring 17 is sleeved on the outer wall of the traction rope 6 between the traction rope 6 and the L-shaped plate 18. The coordinated use of the reset spring 17 facilitates the automatic reset of the push rod 15, thereby facilitating the lifting of the screw and improving the work efficiency of screw cutting.

[0024] In the utility model, a slide bar 19 is provided on the outer wall of the circular plate 16, and a slide groove is provided on the inner wall of the L-shaped plate 18 to cooperate with the slide bar 19; the use of the slide bar 19 facilitates the stable sliding of the circular plate 16, thereby facilitating the lifting of the screw.

[0025] In the utility model, the fixing member includes an annular mounting ring 7 arranged on the bottom surface of the mounting plate 3 and matched with the hexagonal punching head 8. The annular mounting ring 7 is provided with a locking screw 12, and the locking screw 12 passes through the hexagonal punching head 8. The use of the locking screw 12 facilitates the installation of the hexagonal punching head 8.

[0026] In the utility model, the mounting plate 3 is symmetrically provided with a sliding plate 11 , and the inner wall of the U-shaped frame 2 is provided with a strip-shaped sliding groove to cooperate with the sliding plate 11 , so as to facilitate the sliding of the sliding plate 11 and thus facilitate the stable movement of the hexagonal punching head 8 .
