[0013] Furthermore, the lower pressure ring is shaped like a frustum, and its vertical cross-section is trapezoidal;

[0014] The above technical solution can be used well with the connecting groove.

[0015] Furthermore, the connecting structure is made of polyurethane rubber;

[0016] The above technical solution has good wear resistance, oil resistance, low temperature resistance and excellent mechanical strength, as well as good weather resistance.

[0017] Furthermore, the material of the pressure ring is synthetic rubber;

[0018] The above technical solution has high wear resistance and good friction performance.

[0019] This utility model has the following beneficial effects:

[0020] 1. The utility model discloses a connecting structure is provided with, can guarantee the contact area of increasing with the hole in use, reaches better sealing effect, changes the material quality of preparation simultaneously, makes it have good use effect, prolongs the service life of whole.

[0021] 2. The utility model discloses an auxiliary structure is provided with, can be after the use of connecting structure to the top cap is pressed down and makes the press down ring insert into the inside of connecting groove, thereby continuing to the lateral wall of lower connecting body and toping outward, thereby improving the sealing property of connecting place on the basis of originally.
