Furthermore, the outer wall of the clamp ring body is divided into an upper ring surface, an inclined surface and a lower ring surface.

Furthermore, the outer ring groove is formed at the bottom end of the lower ring surface, the distance between the highest surface of the outer ring groove and the outer wall of the bottom of the clamp ring body is 1.75mm-2.25mm, and the distance between the highest surface of the inner ring groove and the outer wall of the bottom of the clamp ring body is 3mm-4 mm.

Furthermore, a smooth transition inner inclined plane is arranged between the inner ring groove and the clamp ring body.

Further, the inclination angle of the inner inclined plane is between 0 and 30 degrees.

Further, the distance between the highest point of the inner inclined plane and the outer wall of the bottom of the snap ring body is 0mm-1 mm.

The utility model has the advantages that:

1. through at least one ladder face of design on the snap ring body, make things convenient for it to cooperate closely with other parts more, be favorable to reducing the gap of contact position to produce a plurality of contact surfaces, increase area of contact between them, and also can play certain effect of blockking in the corner, further improve sealing performance.

2. Through the arrangement of the upper ring surface, the inclined surface, the lower ring surface, the inner inclined surface and the chamfer surface, the number of sharp tips is reduced, stress transition concentration is avoided, and damage caused by stress transition concentration is avoided as much as possible.

3. Through regarding the echelonment structure on the snap ring body as the sign of installation location, make things convenient for the staff to install.
