It has a simple structure and reliable operation. When using it to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

Figure 1 - Figure 6As shown, first, the cooling pipe 107 is connected to the water pipe, and the first clamping block 111 is connected to the flowing air. The cooling water in the cooling pipe 107 generates a large amount of heat, which can quickly cool the hydraulic cylinder.

[0040] Secondly, when the wear-resistant ring 203 needs to be replaced, first press the push rod 212 inward to drive the semi-circular ball 208 to move in the groove 205, and use the ring 210 to slide on the surface of the cylinder 211. At the same time, the elastic block 207 moves along the outside of the ring 210 in the limit groove 206, thereby changing the protruding position of the elastic block 207. When the ring 210 coincides with the semi-circular ball 208, the semi-circular ball 208 can be removed from the groove 205, the limitation of the protective shell 101 on the hydraulic cover 201 can be released, and the wear-resistant ring 203 can be replaced.
