An unfolding and locking mechanism is used for unfolding and locking of a lunar surface lunar landing module, and comprises an unfolding structure and a locking structure. The unfolding structure comprises a vortex coil spring used for providing unfolding power, a rotating wheel, a vortex coil spring shaft, a transmission mechanism and a limiting hook, wherein the vortex coil spring is connected with the vortex coil spring shaft through the rotating wheel, and the vertex coil spring shaft is connected with the transmission structure and the limiting hook. The transmission structure transmits the driving force of the vortex coil spring to an unfolding rack, and the unfolding rack pushes an unfolded part to be unfolded. Meanwhile, the unfolding rack is further provided with a swiveling lever, and a limiting pin is arranged at the end of the swiveling lever. When the vortex coil spring moves, the limiting pin of the swiveling lever moves towards a locking mechanism, after the limiting hook rotates by a certain angle, the hook-shaped part of the limiting hook can be clamped into an opening of a clamping pin shaft, and the locking mechanism is triggered. At the moment, the limiting pin of the swiveling lever just rotates within the capture range of the locking mechanism, and the limiting pin is locked by the locking mechanism. According to the unfolding and locking mechanism, the landing module can be stably unfolded and locked effectively.
