The utility model relates to a lock controlled by micromotor. The utility model comprises a bolt and auxiliary bolt, a control circuit board and control circuit, a micromotor, a microswitch and a lock shell body consisting of a lock shell cover and a lock shell, and is characterized in that the micromotor, the control circuit board and the microswitch are arranged in the lock shell body, and an extension end of a shaft of the micromotor is connected with a worm to drive the worm to rotate, and then the worm drives a worm wheel to rotate; a clutch and a pinion are arranged on the worm wheel with the same main shaft; the pinion is driven to rotate by the clutch, and then drives a large gear to rotate; the large gear is arranged on a lock shaft to drive the lock shaft to rotate; then the lock shaft drives the bolt to stretch, and the auxiliary bolt retracts and drives the microswitch to close and open; the microswitch transmits a signal to the control circuit on the control circuit board to control reversion movement of the micromotor. The utility model has the advantages of no need for long term energization, low power consumption and small noise when closing door, and overcomes the defects of large noise of an electric lock when closing door and failure to lock door of an electromagnetic lock when no power.
