A second protrusion 34 is fixedly connected to the inner surface of the second annular plate 32. The sponge body 35 is engaged with the first annular plate 31 and the second annular plate 32. The first protrusion 33 and the second protrusion 34 can increase the friction between the sponge body 35 and the sponge body 35. A rubber cover plate 37 is engaged with the outer surface of the first annular plate 31 and the second annular plate 32. The cross-section of the rubber cover plate 37 is U-shaped.
