Preferably, the inner wall of the new plastic sliding sleeve is provided with a plurality of slots, and the depth of the slots is 0.1-0.2 cm.

By adopting the technical scheme, when the hydraulic oil flows through the new plastic sliding sleeve, part of the hydraulic oil can flow into the plurality of the slots, when the pressure of the hydraulic oil is larger, the slots can reduce the pressure of the hydraulic oil, and when the depth of the slots is 0.1-0.2cm, the pressure of the hydraulic oil can be reduced, but the hydraulic oil cannot be separated.

Preferably, a plurality of concave holes are formed in the inner side of the Y-shaped ring, and the depth of the plurality of concave holes is 0.1-0.3 cm.

By adopting the technical scheme, when the lower end of the second circular ring is close to the plastic sliding block, the concave hole can ensure that a certain gap is reserved between the second circular ring and the plastic sliding block, so that the second circular ring and the plastic sliding block can move.

Preferably, the size difference between the upper end of the Y-shaped ring and the annular clamping groove is 0.001-0.005 cm.

By adopting the technical scheme, the size difference between the upper end of the Y-shaped ring and the annular clamping groove is controlled to be 0.001-0.005cm, and the sealing property can be further kept.
