The invention discloses a multi-gear locking mechanism which comprises a locking unit, a locking keeping unit and a first elastic piece, the locking unit is configured to rotate through external force so as to be locked with an external locking component, and the first elastic piece is connected with the locking keeping unit and gives elastic force towards the locking unit to the locking keeping unit; a plurality of lock tongues are sequentially arranged on the locking unit in the rotating direction of the locking unit, when the locking unit rotates through external force, the lock tongues sequentially rotate to the locking maintaining unit, and the lock tongues and the locking maintaining unit elastically abut against each other through the elastic force of the first elastic piece; along with the rotation of the locking unit, the spring bolt slides on the locking retaining unit relative to the locking retaining unit; a safety groove is formed in the position, on the sliding path of the spring bolt, of the locking maintaining unit, when the spring bolt slides to be right opposite to the safety groove, the spring bolt enters the safety groove through the elastic force of the first elastic piece, and the locking state of the locking unit and the locking component is maintained through cooperation of the spring bolt and the safety groove.

    本发明公开了一种多挡锁止机构,包括锁定单元、锁定保持单元和第一弹性件,所述锁定单元被配置为通过外力转动以实现与外部的锁定部件锁定,所述第一弹性件连接所述锁定保持单元并给予其朝向所述锁定单元的弹性力;所述锁定单元上沿其转动方向依次设有若干锁舌,锁定单元通过外力转动时,若干锁舌依次转动至锁定保持单元上,锁舌与锁定保持单元通过第一弹性件的弹性力相互弹性抵接,且随着锁定单元的转动所述锁舌在所述锁定保持单元上相对其滑动;锁定保持单元上在所述锁舌的滑动路径上设有安全槽,当锁舌滑动至与所述安全槽正对时,锁舌通过所述第一弹性件的弹性力进入所述安全槽内,通过两者的配合以保持锁定单元与所述锁定部件的锁定状态。
