The connection structure of the piston and the piston rod can be divided into integral type and assembled type, and the assembled type includes screw connection, half ring connection, spring retaining ring connection and cone pin connection. Under normal working conditions, the hydraulic cylinder uses a threaded connection between the piston and the piston rod. However, when the working pressure is high or the load is large, and the diameter of the piston rod is small, the thread of the piston rod may be overloaded. In addition, when the vibration of the working machine is large, the nut fixing the piston may vibrate, so it is necessary to use a non-threaded connection. Therefore, the design of the piston and the piston rod connection is integrated
