A noise reduction mechanism is arranged between the chute 10 and the guide rail 9. The noise reduction mechanism is composed of a trapezoidal block 11, a first guiding wheel 12 and a second guiding wheel 13. The two trapezoidal blocks 11 are fixedly connected to the two inner walls of the chute 10. Trapezoidal grooves 14 corresponding to the trapezoidal blocks 11 are respectively provided on the two side walls of the guide rail 9.
