A second gear 11 is meshed at one end of the first gear 10. A threaded rod 12 is threaded inside the second gear 11. The bottom of the threaded rod 12 is rotatably connected to the top of the dust cover body 2.

[0021] When it is necessary to adjust the height of the dust cover body 2, the motor 8 is started. The motor 8 will drive the rotating shaft 9 to rotate, the rotating shaft 9 will drive the first gear 10 to rotate, the first gear 10 will drive the second gear 11 to rotate, the second gear 11 will drive the threaded rod 12 to move up and down, and the threaded rod 12 will drive the dust cover body 2 to move up and down, which makes it easy to adjust the height of the dust cover body 2, avoids frequent disassembly and installation, and greatly improves work efficiency.

[0022] Furthermore, the bottom of the threaded rod 12 is fixedly connected to a limiting ring 13, and the top of the dust cover body 2 is machined with a limiting groove 14. The limiting ring 13 is rotatably connected inside the limiting groove 14. When the threaded rod 12 rotates, the threaded rod 12 will drive the limiting ring 13 to rotate, and the limiting ring 13 will rotate along the inside of the limiting groove 14. When the second gear 11 rotates, it drives the threaded rod 12 to move up and down, and the threaded rod 12 will drive the dust cover body 2 to move up and down. By setting the limiting groove 14, the limiting groove 14 will limit the movement of the threaded rod 12 and prevent the bottom of the threaded rod 12 from leaving the inside of the dust cover body 2.
