While filtering, the servo motor 402 is started to drive the semicircular gear 403 to rotate through the servo motor 402. When the semicircular gear 403 is engaged with the linkage gear rod 405, the linkage gear rod 405 moves on one side of the guide rail 404, so that the return spring 407 is stretched. When the semicircular gear 403 is separated from the linkage gear rod 405, the return spring 407 rebounds quickly, so that the rubber head 414 on the impact column 413 impacts the filter plate 410. When the lifting workbench 301 is moving, the cleaning brush plate 507 located on the cleaning mounting plate 506 cleans the outside of the cross rail 2 to prevent impurities from adhering to the outside of the cross rail 2. At the same time, the roller 512 is abutted against the arc surface of the anti-deflection block 505, so that the cleaning brush plate 507 is always perpendicular to the cross rail 2 to prevent it from tilting.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
