The invention relates to the technical field of space flight and aviation, in particular to a resettable pressing and releasing device which comprises a pressing device and a releasing device which are connected with each other, the pressing device is fixed to a solar wing panel needing to be pressed and unfolded through a screw, and the releasing device is fixed to a fixing component through a screw. The locking device is matched with a pin puller for locking, locking and releasing of the solar wing sailboard are achieved through tightening and unfolding of the split nuts in the separation nut, and compared with unlocking of assemblies such as an electromagnet, magnetic interference to signals of a whole satellite due to magnet characteristics is avoided; and meanwhile, the problems of unstable magnetic force, low reliability and incapability of realizing electromagnetic unlocking of a small-size device caused by adopting an electromagnet assembly for unlocking are also solved.

    本发明涉及航天航空技术领域,具体涉及一种可复位式压紧释放装置,包括相互连接的压紧装置和释放装置,所述压紧装置通过螺钉固定于需要压紧展开的太阳翼帆板,所述释放装置通过螺钉固定于固定部件。本发明配合拔销器锁紧,通过分离螺母内部分瓣螺母的束紧与展开,实现对太阳翼帆板的锁紧与释放,相比于采用电磁铁等组件解锁,不会因磁铁特性对整星信号造成磁干扰,同时也解决了采用电磁铁组件解锁带来的磁力不稳、可靠性低以及无法实现小尺寸装置电磁解锁的问题。
