A motor 23 is fixedly installed on the top of the worktable 1, and a gear 24 is fixedly connected to the output end of the motor 23. The gear 24 and the circular toothed plate 22... The two parts are meshed together. An electric push rod 25 is fixedly installed on the top of the disc 21. An arc plate 26 is fixedly connected to the output end of the electric push rod 25. A polishing stone 27 is provided on one side of the arc plate 26. A collection box 4 is slidably connected to one side of the worktable 1. The collection box 4 is rectangular in shape. A handle 5 is fixedly installed on one side of the collection box 4. The surface of the handle 5 is polished. A support leg 6 is fixedly installed at the bottom of the worktable 1. The bottom of the support leg 6 is treated with anti-slip treatment. There are four support legs 6, and the four support legs 6 are arranged opposite each other.

[0028] In this embodiment, the output end of the motor 23 drives the gear 24 to rotate. The gear 24 meshes with the circular toothed plate 22, driving the disc 21 to rotate at a constant speed on the worktable 1 through the bearing. At the same time, the electric push rod 25 pushes the arc plate 26 close to the edge of the secondary reflector, so that the polishing stone 27 contacts the edge of the lens. During the rotation of the disc 21, the polishing stone 27 polishes the edge of the lens evenly. The collection box 4 can hold spare items. The support leg 6 has an anti-slip design to ensure the overall stability of the device and avoid displacement during polishing that affects the accuracy.

[0029] Reference Figures 1 to 4 In one aspect of this embodiment, the height adjustment assembly 3 includes an L-shaped frame 31 and a slide rod 32.
