The invention provides a pressing and releasing device. The pressing and releasing device comprises a shell, a pushing mechanism, a self-locking mechanism, a triggering and jacking mechanism and a holding claw mechanism. The released body is installed on the top of the shell and is held tightly by the folded holding claw mechanism. The bottom of the pushing mechanism is installed on a bottom plate of the shell through a thruster, and the top of the pushing mechanism is connected with the self-locking mechanism through a linkage rod. The trigger jacking mechanism is installed on at least one side of the pushing mechanism and used for stretching out after being triggered to press the pushing mechanism at the pre-tightening position or retracting after being triggered to relieve pressing on the pushing mechanism. The holding claw mechanism is arranged on the side, away from the thruster, of the triggering jacking mechanism and connected with the self-locking mechanism through an actuating rod. The self-locking mechanism is configured to realize self-locking when being parallel to the action rod and release self-locking when the parallel state is damaged; the pressing and releasing device does not need to be triggered and released by an initiating explosive device, so that repeated testing and use can be carried out, and the reliability is greatly improved.

    本发明提供了一种压紧释放装置,包括:壳体、推动机构、自锁机构、触发顶紧机构和抱爪机构。被释放体安装在所述壳体的顶部并由收拢的抱爪机构抱紧。推动机构底部通过推力器安装在壳体的底板,推动机构顶部通过联动杆与自锁机构连接。触发顶紧机构安装在推动机构的至少一侧,用于被触发后伸出将推动机构压紧在预紧位置或被触发后缩回以解除对推动机构的压紧。抱爪机构设置在触发顶紧机构远离所述推力器的一侧,利用动作杆与自锁机构连接。自锁机构被配置为与动作杆平行时自锁,平行状态被破坏时解除自锁;本发明的压紧释放装置,无需采用火工品触发释放,从而可进行重复测试与使用,大大提升可靠性。
