The invention relates to a repeatable large-bearing-capacity locking mechanism for a multifunctional interface, and belongs to the technical field of on-orbit assembly. The problems that a locking mechanism is large in vibration and low in reliability are solved. Comprising a driving end and a driven end, the driving end comprises a separation spring, a machine body, a third pull rod, a second pull rod, a first pull rod, a small shaft, a spring, a lock hook and a driving structure, one end of the second pull rod is connected with the machine body, and the other end of the second pull rod is connected with one end of the third pull rod and one end of the first pull rod; the other end of the first pull rod is connected with one end of a lock hook through a small shaft, the other end of the lock hook is connected with the machine body through a spring, the lock hook is matched with the machine body, the small shaft is slidably connected with the machine body, a separation spring is arranged on the machine body, and the separation spring and the lock hook are matched with the driven end. According to the invention, a large load can be borne, and stable connection can be maintained in severe environments such as vibration and impact, so that the reliability and the safety of the whole system are improved.
