The invention relates to a holding claw type on-orbit detachable pressing and releasing mechanism, and belongs to the field of pressing and releasing of spacecraft mechanisms. Comprising a captive screw, a first sliding block, a pressing cap, a holding claw, a first support, a second sliding block, a compression spring, a spring sleeve, a pressing head sleeve, a locknut, a loading nut, a force bearing bowl, a tension spring, a long screw rod, a second support and a pressed part. The working process of the pressing and releasing mechanism comprises the three stages of long screw rod releasing, holding claw holding and pressing and releasing mechanism on-orbit dismounting. And finally, the astronaut integrally takes away the pressing and releasing mechanism and places the pressing and releasing mechanism in a storage bag, and the on-orbit dismounting work of the pressing and releasing mechanism is completed. According to the invention, astronaut on-orbit disassembly can be realized, and the claw type structure is adopted to tightly hold internal parts to realize disassembly, assembly and separation without scattering, and no space debris is generated.
