Working principle: The hydraulic transmission is to drive the piston in the working cylinder to move in a straight line through the pressure oil output by the oil pump, so that when the piston moves upwards, the sealing air in the working chamber is compressed into the oil chamber, and the high-pressure gas is discharged through the overflow hole; When it moves down to the lowest position, the slider is pushed by the spring to move in a vertical direction, and the air valve is opened to release the air at the same time.
