One end of the connecting part 21 is connected to the cylinder 11, and the other end is connected to the cylinder 11. One end is slidably connected to the knocking rod 23 through a guide member 22. The guide member 22 is used to guide the knocking rod 23 to move axially along the cylinder 11 when the knocking rod 23 is knocked. The knocking rod 23 is used to apply a knocking force to separate the bearing from the bearing sleeve. The knocking rod 23 applies a knocking force toward the screw 4 in the dustproof hole 301 of the bearing sleeve 3. The knocking force acts on the steel gasket 5, and then has a knocking effect on the bearing 6, causing the steel gasket 5 and the bearing 6 to fall off downward and fall into the cylinder 11.

[0028] In this embodiment, in order to apply the knocking force to the screw 4, the knocking rod 23 comprises a first guide sleeve 231 and a round rod 232, the first guide sleeve 231 is connected on both sides of the round rod 232, and is sleeved with the guide rod 221 one by one and can slide along the guide rod 221, and the round rod 232 is used for inserting into the thread hole of the dustproof hole of the bearing sleeve and abutting to the inner hexagonal hole of the bearing sleeve and the core connection screw of the leather roller.
