Under the action of the control plate 721, the control rod 720, and the moving rod 710, the placement plate 711 is controlled to separate from the sleeve. At the same time, under the action of the moving ring 718 and the inclined plate 716, multiple clamping blocks 714 are controlled to separate from the sleeve, which facilitates the sleeve falling into the collection box 4 under the action of gravity. At the same time, the control plate 721 drives the L-shaped plate 730 to move. Under the action of the toothed plate 735, the gear 2 734, the double screw 2 733, the control block 731, and the stabilizing plate 727, the auxiliary wheel 729 is separated from the sleeve, which facilitates the rapid discharge of the sleeve.
