Still further, the second cylinder 5 drives the coiling barrel 10 to extrude the abutting plate 13 to slide in the process of pushing the coiling barrel 10, the sliding of the abutting plate 13 drives the supporting plate 15 to slide so as to separate the supporting plate 15 from the guiding plate 7, the guiding plate 7 compresses the supporting spring 12 to incline downwards, the coiling barrel 10 slides down along the inclined guiding plate 7, when the guiding plate 7 inclines, the abutting plate 13 is pulled to reset under the elastic force of the second spring 14, and the supporting plate 15 is reset due to the reset of the abutting plate 13. The effect of this design is that the tilting of the guide plate 7 occurs after the sliver has been cut, i.e. the guide plate 7 tilts after the sliver has been cut to slide down the can 10 so that the sliver is not pulled out of the can 10 by pulling the sliver when the can 10 slides down.
