After the cover plate 34 is disposed, the upper material guiding channel 311, the lower material guiding channel 312, the chute 313 and the material distributing channel 321 can be conveniently processed. The cover plate 34 covers the surface of the distributing block 31, the upper material guiding channel 311, the lower material guiding channel 312 and the sliding chute 313 form a peripheral closed channel through the matching of the distributing block 31 and the cover plate 34, and the distributing channel 321 forms a peripheral closed channel through the matching of the cover plate 34 and the distributing slide block 32.
