Rotate and withstand axial force. The lower thrust ring 25 is threaded in the middle of the shoe boot joint 27 , and the anti-rotation screw 24 is threaded into the outer threaded hole of the lower thrust ring 25 to prevent the lower thrust ring 25 from loosening after tightening. The lower bearing 23 can bear the downward axial impact force generated by the piston rod 10 and transmit it to the shoe 28 through the lower thrust ring 25 . A buffer washer 2 is installed between the upper joint 1 and the upper cylinder liner 3 , which can compensate the length error during axial assembly and can buffer the upward impact force of the piston rod 10 . The piston upper seal 5 is installed in the inner hole of the upper cylinder liner 3 , and the piston rod 10 can reciprocate in the axial direction relative to the piston upper cylinder liner 3 . The middle sealing cylinder 9 is connected with the upper piston cylinder 6 through threads, and the maximum diameter of the upper part of the piston rod 10 (ie the annular piston) is installed in the cavity formed by the upper cylinder liner 3, the upper piston cylinder 6 and the middle sealing cylinder 9, and can move along the axis. Reciprocating motion and free rotation. The upper end of the lower joint 17 of the piston cylinder is connected with the middle sealing cylinder 9 through threads. The positioning screw 15 passes through the outer through hole at the lower part of the middle sealing cylinder 9 and then is screwed on the guide sleeve 11 to ensure that the guide sleeve flow channel 36 of the guide sleeve 11 is flush with the flow hole 31 of the middle sealing cylinder 9 (refer to Figure 12) .

Referring to FIG. 5 , the lower end of the piston rod 10 is connected with the inner hole of the shoe-in joint 27 through a spline sleeve structure, which can reciprocate relative to the axial direction and transmit torque to the shoe-in 28 . When the piston rod 10 is at the lower end position as shown in FIG. 1 , the liquid flowing through the nozzle 26 produces a pressure drop, causing the pressure in the inner hole of the piston rod 10 to be higher than the pressure at the lower end of the nozzle 26 . , The lower joint hole 33 of the piston cylinder and the upper hole 29 of the upper piston cylinder are communicated with the upper hydraulic chamber 30 of the piston rod 10 to maintain the same pressure (low pressure).
