The invention discloses a screw top piece composite transmission type electric suction lock which comprises a base plate, a cover plate, a lock piece composite transmission mechanism, a screw electric pushing mechanism and an electric control system. The locking plate composite transmission mechanism is composed of a driving locking plate and a non-return locking plate, and the locking plate composite transmission mechanism is endowed with a reverse rotation trend through a torsion spring. The screw electric pushing mechanism drives the movable seat to move through the screw, and the unlocking top sheet at the lower part of the movable seat can respectively push the driving locking sheet to rotate clockwise for locking or push the non-return locking sheet to rotate anticlockwise for releasing; the electric control system detects the positions of the locking plate and the rack through the three microswitches and controls the motor to rotate forwards and backwards so as to achieve automatic switching of the unlocking state, the semi-locking state and the full-locking state. The locking device is compact in structure, reliable in transmission and capable of accurately recognizing and executing the locking state, the safety is improved, and the service life is prolonged.
