[0023] The piston rod 8 moves in the inner cavity of the connecting channel 6 , the oil inlet channel 5 and the oil outlet channel 7 are not level, and the height of the piston rod 8 is consistent with the diameter of the oil outlet channel 7 .

[0024] The inner wall of the connecting channel 6 is connected with a retaining ring 16 , the retaining ring 16 is located below the piston column 8 , and the retaining ring 16 is located above one end of the oil inlet channel 5 .

[0025] In this embodiment, when the flow of hydraulic oil needs to be controlled, the handle 11 can be used to drive the rotating block 10 to rotate the screw 9. At this time, the screw 9 moves in the inner cavity of the threaded barrel 12 through the thread, and drives the piston column 8 to move up and down, thereby adjusting the size of the entrance of the oil inlet channel 5 to achieve the purpose of controlling the flow of hydraulic oil, so that the practicality of the device is improved. The retaining ring 16 plays a limiting role. When one end of the piston column 8 is in contact with the retaining ring 16, the piston column 8 completely blocks the oil outlet channel 7, thereby achieving the purpose of cutting off the flow.
