The inner part includes multiple first slots and second slots defined axially in the outside thereof. Each first slot receives a pin therein, and each second slot receives a roller therein. A rod extends through a dust-proof unit, a first ring and a spring. The lower section of the rod is connected to the top end of the inner part. An outer part is a tube which includes multiple first grooves and second grooves defined axially in the inner periphery thereof. The outer part is mounted to the inner part. The pins are partially accommodated in the first grooves, and the rollers are partially accommodated in the second grooves.
