The outside of the cam 19 is in contact with the rear outside of the stop plate 20, and the design of the cam 19 should ensure that it can smoothly convert the rotary motion of the handle 18 into the linear motion of the stop plate 20.

[0036] The front side of the abutting plate 20 is in contact with the rear side of the clamping plate 2, and the abutting plate 20 is directly acted on by the cam 19, which converts the rotary motion of the cam 19 into linear motion to push the clamping plate 2 to achieve the unlocking action.

The bottom of the top column 28 is in contact with the outside of the connecting column 5, and will press the top column 28 upward with the rotation of the connecting column 5. When the top column 28 is not stressed, the spring 1 is no longer stressed and compressed, and generates a counterforce on the top plate 27. At this time, the inside of the hydraulic chamber 25 generates negative pressure to extract the lubricating oil in the inside of the oil storage box 22 through the connecting pipe 24. The top column 28 is forced to move again, and the air pressure in the inside of the hydraulic chamber 25 increases to squeeze out the lubricating oil again.
