The inside of the cylinder is divided into rod cavity and rodless cavity by the piston. When compressed air is input from the rodless cavity, the rod cavity exhausts. The force formed by the pressure difference between the two chambers of the cylinder acts on the piston overcomes the resistance load and pushes the piston movement, so that the piston rod extends out. The piston rod is retracted when there is a rod cavity for intake and no rod cavity for exhaust. If the rod-cavity and rod-cavity alternate intake and exhaust, the piston realizes reciprocating linear movement .
