[0036] The feeding barrel 31 is fixedly connected with a telescopic mechanism I 37, and a pulling bracket 38 is fixedly connected to the telescopic end of the telescopic mechanism I 37. The transmission belt between the conical friction wheel II 35 and the conical friction wheel I 34 passes through the pulling bracket 38.
