The invention relates to the field of locking and unlocking tools, in particular to a locking and unlocking sleeve and a locking and unlocking device, and aims to solve at least one of the problems that in the prior art, a locking and unlocking sleeve is limited in application range, too large in noise and serious in first tooth abrasion. In order to achieve the purpose, the locking and unlocking sleeve comprises a sleeve body which is arranged on a transition body in a sliding mode in the axial direction; the first elastic piece is arranged between the sleeve and the transition main body, and the first elastic piece is arranged to enable the sleeve to move between a first position and a second position; the transition body is arranged on the sleeve base in a sliding mode in the axial direction. The second elastic piece is arranged between the transition body and the sleeve base, and the second elastic piece is arranged to enable the sleeve to move between the second position and the third position when the sleeve reaches the second position under the action of the first elastic piece. Through two-stage stroke step-by-step compression, the change range of the elastic force of the locking and unlocking sleeve is expanded, so that the locking and unlocking sleeve can adapt to various locking mechanisms.
本发明涉及加解锁工具领域,具体提供一种加解锁套筒及加解锁装置,旨在解决现有技术中的加解锁套筒适应范围有限,噪音太大以及首牙磨损严重中的至少一个问题。为此目的,本发明的加解锁套筒,包括:套筒沿轴向滑动设置在过渡主体上;第一弹性件设置在套筒和过渡主体之间,第一弹性件被设置成能够使套筒在第一位置与第二位置之间移动;过渡主体沿轴向滑动设置在套筒底座上;第二弹性件设置在过渡主体和套筒底座之间,第二弹性件被设置成当套筒在第一弹性件的作用下到达第二位置后,第二弹性件能够使套筒在第二位置与第三位置之间移动。通过两级行程逐级压缩,扩大了加解锁套筒弹力的变化范围,使其能够适配多种锁止机构。
