The utility model discloses further set up to: and two sealing rings are arranged on the outer wall of the piston.

Through above-mentioned technical scheme, make the sealing washer realize sealed to the inner wall of piston and mounting groove, prevent that hydraulic oil from flowing through the gap, causing the oil leak.

The utility model discloses further set up to: and the two sealing rings are in interference connection with the mounting groove.

Through the technical scheme, the piston and the sealing ring can be better sealed in the center of the mounting groove, and can move through the movement of the bolt.

The utility model discloses further set up to: the inner circumferential surface of the locking groove is provided with an internal thread, and the bolt is positioned in the center of the internal thread.

Through the technical scheme, the bolt can rotate at the center of the locking groove, so that the movement of the piston is controlled, and the adjustment of the size of the gap is realized.

The utility model has the advantages as follows:

1. the utility model discloses a plurality of spare parts that set up make can be through to annotating oil pipe way center injection hydraulic oil, make hydraulic oil get into the cavity, make partly hydraulic oil overflow mounting groove center simultaneously, rethread bolt tightening locking groove to reach certain moment of torsion, make the bolt drive the piston and remove, extrude hydraulic oil into the cavity, extrude integral type axle bush inner wall, can adjust the clearance size, the degree of adjustment of clearance size can be controlled through the oil pressure size, the result of use is better, application scope is wider;

2. the utility model discloses a lubrication groove or the oil film that sets up for frictional force is minimum between integral type axle bush inner wall and the axle, and the wearing and tearing that make the integral type axle bush receive are lower, have promoted life, excellent in use effect.
