The slider 331 has a locking position in which the locking tooth is inserted into the rack 21 and an unlocking position in which the locking tooth is pulled out of the rack 21. The slider 331 slides between the locking position and the unlocking position. The rotating shaft 332 is rotatably mounted to the outer shell 31. The slider 331 is formed with a waist-shaped groove. The trigger 333 is mounted to one end of the rotating shaft 332. An eccentric column is provided at the other end of the rotating shaft 332. The axis of the eccentric column deviates from the rotation axis of the rotating shaft 332; the eccentric column is inserted into the waist-shaped groove.

[0026] The direction of the rotation axis of the rotating shaft 332 is parallel to the length direction of the rack 21 and perpendicular to the sliding direction of the slider 331. When the rotating shaft 332 rotates, the slider 331 is driven to slide between the locking position and the unlocking position through the eccentric column.
