Through adopting above-mentioned technical scheme, the width of ring channel tank bottom is less than the width of ring channel notch, and when the elastic component was located the ring channel, on the cylinder was located to the cover body cover, and the cylinder extruded the conical surface of slope section, made the ring channel shrink inwards, the ring channel after the shrink made cell wall extrusion elastic component, and then made the elastic component more stable in the ring channel.

To sum up, the beneficial technical effect of this application does:

1. the edge of the limiting bulge is provided with the arc-shaped chamfer, when a plurality of sleeve bodies are put together for transportation, the arc-shaped chamfer is smooth, and when the adjacent sleeve bodies collide, the limiting bulge is not easy to abrade the sleeve bodies, so that abrasion of the sleeve bodies during transportation is reduced;

2. the side surface of the limiting protrusion, which is close to the limiting groove, is an inclined surface, so that the width of the limiting groove is gradually increased from one end close to the sleeve body to one end far away from the sleeve body, when the sleeve body enters the limiting groove in the transportation process, the limiting protrusion is more easily slid out of the limiting groove, and the abrasion of the limiting protrusion on the limiting groove is reduced;

3. the inclined plane of slope section inclines to the mounting hole center, and when the cover body cover was located on the cylinder, the inclined plane of slope section and cylinder looks butt and hug closely the cylinder, made to be connected more firmly between the cover body and the cylinder.
