The invention discloses a bionic 4D printing multi-factor triggering satellite locking and releasing device, which belongs to the technical field of spaceflight and bionic 4D printing, and comprises an electromagnetic radiation prevention heat insulation shell, an upper shape memory bionic locking mechanism, a satellite buffering heat insulation fixing table, a lower shape memory bionic locking mechanism, a telescopic energy storage ejection mechanism and a rocket connecting base. The upper shape memory bionic locking mechanism is of an electrostrictive shape memory structure and is a first-stage locking and releasing mechanism of the satellite, locking grooves are evenly distributed in the satellite buffering and heat-insulating fixing table and are lower shape memory bionic locking mechanisms of the satellite, and the satellite is locked or separated from the satellite buffering and heat-insulating fixing table through magnetic shape memory T-shaped locking pieces evenly distributed on the lower portion of the satellite buffering and heat-insulating fixing table. The locking and releasing mechanism is a secondary locking and releasing mechanism of the satellite; telescopic energy storage ejection mechanisms are evenly distributed on the lower side of the satellite buffering heat insulation fixing table and composed of shape memory springs and shape memory electrostriction pieces, and the lower portions of the telescopic energy storage ejection mechanisms are connected with the lower end of the electromagnetic radiation prevention heat insulation shell. Response is fast, impact is small, and reliability is high.
