Referring to fig. 17, the other structure in the present embodiment is the same as embodiment 1 except that: the pressing piece is a pressing block 13-5, the pressing driving mechanism is a telescopic cylinder 13-6, a cylinder body of the telescopic cylinder 13-6 is installed on the side face of a 7-shaped installation plate 13-1 through a support 13-7, and the pressing block 13-5 is fixedly connected to the telescopic piece of the telescopic cylinder 13-6. Through the mechanism, when the telescopic cylinder 13-6 drives the telescopic piece to move towards the side surface of the 7-shaped mounting plate 13-1, the belt 5-4 is tightly propped against the side surface of the 7-shaped mounting plate 13-1, so that the power connection between the belt 5-4 and the 7-shaped mounting plate 13-1 is realized; when the telescopic cylinder 13-6 drives the telescopic piece to move reversely, the power of the belt 5-4 and the 7-shaped mounting plate 13-1 is disconnected.

The present invention is not limited to the above embodiments, and any other changes, modifications, substitutions, combinations, and simplifications which do not depart from the spirit and principle of the present invention should be construed as equivalents and are included in the scope of the present invention.
