Turning the knob b11 drives the threaded rod b10 to rotate. The outer wall of the threaded rod b10 is threadedly connected to a positioning plate b4. The inner wall of the positioning seat 2 is fixedly connected to a guide rod 12. The outer wall of the guide rod 12 is slidably connected to the inner wall of the bottom of the positioning plate b4. The bottom of the positioning plate b4 is slidably connected to the inner wall of the positioning seat 2. The threaded rod b10 rotates to drive the positioning plate b4 to change its position along the guide rod 12, and the positioning plate a3 is cooperated to position the material. A marking component is fixedly connected to the outer wall of the workbench 1, and the marking component includes a support frame 13. The bottom of the support frame 13 is fixedly connected to the outer wall of the workbench 1. The inner wall of the support frame 13 is slidably connected to an outer shell 14, and the outer shell 14 can be controlled to slide along the inner wall of the support frame 13 by a lifting device. A laser marking head 15 is fixedly connected to the end of the outer shell 14, and the laser marking head 15 is started to mark the material.

[0032] Reference Figure 1 , Figure 2 and Figure 4The outer wall of the workbench 1 is fixedly connected with a cylindrical block 16, and a circular groove 17 is opened on the side wall of the positioning seat 2. The outer wall of the cylindrical block 16 is plugged into the inner wall of the circular groove 17.
