延伸到壳体外的按压部为一个按键。
当然， 延伸到壳体外的按压部亦可以是一个拨杆。
所述锁钩有两个， 两个锁钩上下叠放， 锁钩复位装置的推压部抵顶在两 个锁钩的后端部， 两个锁钩的前端部分别对应穿插在壳体上的两个锁扣卡位 中。
当然， 所述推压部亦可以与锁钩的前端部抵顶配合。
或者， 所述推压部与锁钩的中部抵顶配合。
所述锁钩复位装置为一个 "L "形或 "V "形的异形件， 其转折处为铰接 占、、、。
本实用新型的有益效果： 本实用新型是在壳体内设置有一个用于将锁钩 的前端部推回壳体内的锁钩复位装置， 锁钩复位装置的中部铰接在壳体上， 锁钩复位装置从铰接点分别延伸出一个推压部和一个按压部， 推压部抵顶于 锁钩上， 按压部延伸到壳体外， 它是通过一个应用杠杆原理制成的锁钩复位 装置将锁钩的前端部退回壳体内， 通过对按压部的控制使锁钩退回壳体内， 达到轻松省力的目的。
