The common spring type air cylinder is mostly a built-in spring type air cylinder. The built-in spring cylinder generally includes a piston and a pneumatic actuator (i.e., a cylinder), the piston divides an inner cavity of the pneumatic actuator into two parts, if the cylinder is vertically disposed, the cylinder is divided into an upper cylinder and a lower cylinder, the upper cylinder is above the piston, and the lower cylinder is below the piston. The working principle is that compressed air is introduced into an air inlet at one end (an upper cylinder or a lower cylinder) of an air cylinder, and a piston compresses a spring to move towards the other end under the action of gas pressure; when the air inlet end is decompressed, the piston is restored to the initial position under the action of the spring force.
