When the piston rings 53 at both ends of the expansion sleeve 52 slide toward each other, the piston ring 53 squeezes the two ends of the expansion sleeve 52 to drive the two ends of the expansion sleeve 52 to bend inward and hold tightly.
[0024] When in use, the oil circuit between the fixed sleeve 51 and the piston ring 53 is connected to the oil pump, and the oil is input or output in the oil circuit through the oil pump to drive the piston ring 53 by oil pressure, so that the piston rings 53 at both ends slide toward or oppositely in the fixed sleeve 51.
