The invention discloses a novel swing type micro-mechanical locking structure, which includes a swing unit and a mechanical latch unit. The swing unit includes a swing body, a rotary shaft driven by amotor, a slot for rotating the rotary shaft and matching with the rotary shaft, a pair of intermeshing micro-gear and rack, and a swinging connecting rod swinging under the drive of the gear. The mechanical latch unit includes a resilient hook, an anti-off boss, and a latch base. In the invention, the rotation of the rotating shaft driven by the motor is converted into the swing of a swinging assembly, and then the locking is achieved through the joint action of the resilient hook and the anti-off boss. The novel swing type micro-mechanical locking structure is simple in structure and easy toprocess, reduces the production cost while increasing the production efficiency, and has a good locking effect.
