When a user rotates the handle 40 relative to the first cylinder 11 and pushes the first piston 12 to move in the hydraulic cylinder, the oil in the working chamber 211 pushes the second piston 22 to move forward, and the power spring 25 can release the elastic force, so that the oil in the working chamber 211 pushes the second piston 22 to move forward, and further, the energy-saving effect can be achieved. In addition, when the user releases the acting force on the handle 40, the positioning steel ball 24 of the second piston 22 can be always abutted against the clutch push rod 70 under the action of the boosting spring 25, so that the positioning steel ball 24 of the second piston 22 is always kept in contact with the clutch push rod 70 without collision.

The dust cover 100 is provided with a through hole 101 through which the adjusting rod 50 passes, and the stopper 110 is connected to the dust cover 100 and blocks the through hole 101.

Through set up stop collar 110 and elastic component 120 on adjusting pole 50, and connect dust cover 100 on stop collar 110 to make stop collar 110 and dust cover 100 support all the time to lean on in rotating seat 80 under the effect of elastic component 120, thereby rotate and reset back dust cover 100 at handle 40 relative first cylinder body 11 and can reset under the effect of elastic component 120 and stop collar 110, and resume deformation, and then guarantee dust-proof effects of dust cover 100. In addition, the dust cover 100 is provided with a through hole 101 through which the adjusting rod 50 passes, and the through hole 101 can be blocked by the stop sleeve 110, so that dust is prevented from entering the working environment of the first piston 12 from the through hole 101.

For example, as shown in fig. 3, the elastic member 120 is a spring, the spring is sleeved on the outer side of the adjustment lever 50, one end of the spring abuts against the shoulder of the adjustment lever 50, and the other end abuts against the limiting sleeve 110.

In this embodiment, with continued reference to fig. 3, one end of the first piston 12 is provided with a limit groove 122 into which one end of the adjustment rod 50 is snapped. The limiting groove 122 is formed in one end, abutting against the adjusting rod 50, of the first piston 12, and one end of the adjusting rod 50 is clamped into the limiting groove 122 of the first piston 12, so that the adjusting rod 50 is guaranteed to act on the first piston 12 all the time, the adjusting rod 50 is prevented from sliding sideways with the first piston 12 when the first piston 12 is pushed to move relative to the first cylinder 11, and the adjusting rod 50 is further caused to act on the cylinder wall of the first cylinder 11 and scrape against the cylinder wall of the first cylinder 11.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
