After the adjustment is completed, the push button 405 is pushed to make the locking piece 413 compress the spring two 412 again to slide, and the rotating piece 407 is reset under the elastic action of the spring one 411, locking the rotating rod 404 and the gear 406, and at the same time fixing the position of the sliding column 402 so that it cannot slide and locks the current tension; when in a working environment with serious dust pollution, the air can be filtered through the filter plate 502, and at the same time, the motor 508 is started to rotate the toothless gear 507, and the sliding rod 509 is driven to stretch the spring four 505 to slide through the meshing of the rack two 506. When the toothless gear 507 is disengaged from the rack two 506, the spring four 505 rebounds, driving the impact column 510 to impact the filter plate 502, so that the filter plate 502 vibrates under the action of the spring three 501, to avoid dust accumulation and blockage of the filter plate 502.
