When the hydraulic cylinder is used to realize reciprocating motion, a speed reduction device can be omitted, and there is no transmission gap, so that the motion is stable. Therefore, the hydraulic cylinder is widely used in hydraulic systems of various machines. The hydraulic cylinder is basically composed of a cylinder sleeve, a cylinder cover, a piston, a piston rod, a sealing device, a buffer device and an exhaust device.
