[0030] Please refer to Figures 1-4 , the deflecting member 50 includes a telescopic cylinder 51 and a rocker arm 52. The telescopic cylinder 51 is hinged to the set of frames 23, the rocker arm 52 is fixedly connected to the roller frame 30, and the telescopic end of the telescopic cylinder 51 is hinged to the outer end of the rocker arm 52.
