ABSTRACT:
A shockproof spindle includes a spindle inserted into an elastomer having a compressible structure, and a sleeve having a hollow cylinder, sequentially. The sleeve caps the elastomer while the elastomer is pressed on the top of the base fixed at the bottom end the spindle to expose the chute of the spindle. The ball is then disposed in the chute of the spindle and the chute of the sleeve. After the sleeve is released to return the elastomer to its normal state, the sleeve, the elastomer and the spindle are held together by the ball which is retained in the chutes of the spindle and the sleeve. A C-shaped plate is then inserted between the elastomer and the base.
