Through the interaction between the lever and the movable ring, as well as the interaction between the guide plate and the guide groove, and the interaction with the connecting plate, the movable ring can drive the sleeve to move back and forth. This allows the oil-cleaning cotton to remove oil from the straightened brass rod body. Tightening the fastening bolts can remove and install the sleeve from the holder for replacement, so that the sleeve can be adapted to brass rod bodies of different sizes.
