The utility model is further set to: described shock-absorbing main body outer peripheral surface is provided with adjustment screw thread, and described dustproof annulus inner peripheral surface is provided with the annulus screw thread 62 suitable with adjusting screw thread, and the dustproof convex tendon of described annular cross section is wedge shape.
By adopting technique scheme, adjust match with the dustproof groove of the annular gap length of formation of the dustproof convex tendon of annular by rotating dustproof annulus, people can be adjusted as required, and can be by the rotation annulus that prevents dust, dustproof annulus is separated, the dust of the dustproof convex tendon of easy cleaning annular and the dustproof groove surfaces of annular with dust-proof cover.
The utility model is further set to: between the dustproof groove of described annular and the dustproof convex tendon of annular, be filled with air-filtering particle.
By adopting technique scheme, improve the filtration to air.
