[0012] Beneficial Effects

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1.

The front end of the device is extended into the middle of the bushing, and the motor inside the frame is started to drive the threaded sleeve inside the connecting sleeve to rotate. When the threaded sleeve rotates, the threaded rod will extend forward in the middle of the threaded sleeve due to the limitation of the telescopic rod, and then push the conical head forward. When the conical head extends into the middle of the fixed ring, the extrusion plate will be gradually squeezed due to the conical shape of the conical head, and the extrusion plate will push the movable ring outward through the connecting rod, and the outer wall of the movable ring will contact the inner wall of the bushing. The pressure generated forms a large friction force, so that the bushing can be unlocked, and the operation is very convenient.

When the outer wall of the movable ring contacts the inner wall of the bushing, a greater friction force is generated due to the anti-slip strip on the outer wall of the movable ring. The electric push rod extends forward to make the gasket at the front end contact with the parts around the bushing, and then the electric push rod continues to extend to push the frame backward. The frame will drive the fixed ring and the movable ring to move backward through the connecting sleeve, unlocking and removing the bushing. The operation is simple and convenient.
