Furthermore, the position between the piston of the power cylinder and the push rod is locked through a locking screw.

Furthermore, a boss is arranged at the axle center of one end of the first oil cavity.

Furthermore, a second oil chamber is arranged at the front end of the first oil chamber, and an oil filling hole is formed in the inner wall of the second oil chamber.

Furthermore, a sealing plug is arranged in the hole of the oil filling hole for sealing.

Furthermore, a clutch plate is arranged at one end of the push rod and positioned outside the power cylinder.

Furthermore, a clamping groove is formed in the other end of the push rod and located outside the power cylinder.

Compared with the prior art, the utility model discloses at least, including following beneficial effect:

the utility model extends out of the two ends of the power cylinder through the push rod; and a first oil cavity is arranged in the power cylinder, a power cylinder piston is arranged in the first oil cavity by the push rod, a return spring is arranged between the power cylinder piston and the first oil cavity, and the clutch plate is quickly returned when losing external force through the return spring, so that the clutch is thoroughly separated, and the sensitivity of the clutch is improved.
