[0021] The inner diameter of the limit groove 2 is matched with the outer diameter of the moving block 6. The moving block 6 is slidably connected to the inside of the limit groove 2. The shape of the moving block 6 is T-shaped. The threaded rod 14 is located below the limit groove 2. The side of the moving block 6 is threadedly connected to the outer side of the threaded rod 14 through a threaded hole. The driving motor 13 rotates the threaded rod 14, and the threaded rod 14 is used to drive the moving block 6 to move under the limiting effect of the limit groove 2. The outer diameter of the rack 7 is matched with the outer diameter of the gear 9, and the gear 9 is meshed with the rack 7. A slide groove for placing the output end of the grinder 14 is provided on the side of the cover 12. Both sides of the cover 12 are fixedly connected to the connecting plate 11.

The motor 13 and the grinder 14 are both prior arts, and their specific structures, working principles and electrical connection relationships are not described in detail here.

[0022] Working principle: when in use, the staff turns the handwheel at one end of the two-way threaded rod 16 to drive the two clamps 17 to move toward each other synchronously, and the limit rod 18 ensures the stability of the movement of the clamp 17 until the hardware is clamped and fixed to prevent the hardware from loosening during the grinding process. Then the motor 3 is driven to make the threaded rod 4 rotate, and further the moving block 6 moves under the limiting action of the limiting groove 2. During the movement, the rack 7 will drive the sleeve 8 and the gear 9 on one side to rotate, so that the threaded rod 10 drives the cover shell 12 to move downward. At the same time, the telescopic column on the other side of the cover shell 12 cooperates with the lifting to limit, ensuring the stable movement of 12 in the vertical direction until the cover shell 12 covers the surrounding of the hardware, grinds through the baffle 15 and uses the cover shell 12 to prevent burrs and debris from flying out and injuring people. After grinding is completed, the motor 3 is driven again to move the moving block 6, and the sleeve 8 is driven to rotate again, so that the cover shell 12 moves upward to facilitate the removal of the hardware.
