The invention relates to a spacecraft parking mechanism, and belongs to the field of space station cargo transportation. The spacecraft parking mechanism comprises an active end and a passive end. Theactive end comprises a three-jaw connecting mechanism, a spring push rod separation mechanism, a ball screw transmission mechanism, a worm and gear self-locking mechanism, an active end shell, an active end electric interface, a push disc and a fixed disc; the passive end comprises a passive end shell, a passive end disc spring assembly, a passive end electric interface and a passive end guide directional hole; after the active end is aligned with the active end under the driving of the space mechanical arm, the three-jaw connecting mechanism is rotated outwards to be opened; the active end continues to move towards the driven end until the active end electric interface is inserted into the passive end electric interface and is inserted in place; three clamping jaws of the three-jaw connecting mechanism rotate inwards to be closed, and locking and fixing are achieved. Mechanical connection between carried goods and a space station can be achieved under the assistance of the space mechanical arm, the goods can be parked in the space station, and stable parking can be kept for a long time. When separation is needed, low-impact reliable separation is realized.
