after returning, the left pedal 11 is stepped to downwardly displace the left pedal 11, the fourth pull rope 22 and the seventh pull rope 17 are pulled, the seventh pull rope 17 is pulled to contract the cleaning block 25 into the cleaning block sliding groove 31, the fourth pull rope 22 is pulled to rightward displace the left toothed plate 72 to the right limit position, so that the toothed plate fixture block 75 at the left side is abutted against the inner wall at the left side of the toothed plate 72 at the left side, and the shoe cover pedal 19 is stepped on again, so that the support rod 38 is displaced downwards, so that the left second transmission gear 56 rotates to drive the left second winding wheel 57 which is coaxial with the left second transmission gear to rotate and tension the third pull rope 24, so that the pulling plate 67 drives the cross rack 66 to extend into the first transmission gear cavity 49 to be meshed with the first transmission gear 52 and drive the first transmission gear 52 to rotate, thereby driving the first winding wheel 53 coaxial with the first transmission gear 52 to rotate and tighten the first pull rope 50, so that the clamping push block 62 is contracted into the clamping push block sliding groove 33 to finish clamping;

after finishing trampling to shoe cover pedal 19, shoe cover pedal 19 upwards displacement under the effect of shoe cover pedal spring 20, thereby make lug 41 upwards displacement extrusion shifting plate 42 promote and dial the taut sixth stay cord 35 of board slider 46 forward displacement, make pinion rack fixture block 75 downward displacement and pinion rack 72 break away from the butt, thereby make pinion rack 72 reply initial position under pinion rack spring 71's effect, taut sixth stay cord 35 makes the upwards displacement of cleaning block fixture block 37 break away from the butt with cleaning block 25, thereby make cleaning block 25 reply initial position and clean shoe cover 28.
