[0030] Implementation steps of the first innovation point:

[0031] The ramming rod 26 on the transmission rod 27 is rotated simultaneously by the operation of the second driving motor 10. When the ramming rod 26 rotates below the oil plug 21, then the oil plug 21 is pushed upward. At the same time, the sealing gasket 19 moves upward, and the lubricating oil in the oil box 17 flows out through the gap between the oil plug 21 and the oil hole 20, and then drips downward onto the driving motor 12 for lubrication.

[0032] Implementation steps of the second innovation point:

[0033] The first drive motor 7 operates to rotate the lead screw 16. Through screw-thread fit, the moving sleeve 15 drives the movable plate 4 to move leftward. Then, one end of the cutting roller 3 moves away from inside the rotating shaft 8, and then the cutting roller 3 is pulled out leftward, so that the other end of the cutting roller 3 moves away from inside the movable shaft 14, and the cutting roller 3 is disassembled.
