[0042] In addition, when the personnel are rolling up the dustproof cloth 505, the dust on the surface of the dustproof cloth 505 can be cleaned by the cleaning structure 6 during the rolling process of the dustproof cloth 505. When the cleaning brush 603 needs to be replaced after a long period of use, the personnel can first use the connecting block 610 to drive the connecting plate 611 and the iron block 612 to move away from the magnetic block 609, wherein the magnetic block 609 and the iron block 612 can fix the connecting block 610, and prevent the connecting block 610 from moving and causing the slider 604 to slide out of the inner wall of the slide groove 605. Then the connecting plate 611 slides on the arc surface of the limiting rod 613, wherein the limiting rod 613 can play a role in fixing the connecting block 610. The limiting effect of the connecting plate 611 can prevent the connecting plate 611 from being misplaced during the sliding process on the inner wall of the auxiliary groove 607, and then the connecting plate 611 drives the adjusting plate 608 to move in the direction away from the slider 604. When the adjusting plate 608 is completely away from the slider 604, the personnel can move the cleaning brush 603 to move away from the slide groove 605. The cleaning brush 603 drives the slider 604 to move away from the slide groove 605. At this time, the personnel can replace the cleaning brush 603. By setting the cleaning structure 6, the effect of allowing personnel to quickly clean the dust on the surface of the dustproof cloth 505 is achieved.
