An electric door lock includes a deadbolt, a deadbolt operating spindle, a door handle, and a coupling mechanism. The spindle is coupled to the deadbolt and is capable of driving movement of the deadbolt between locking and unlocking positions. The coupling mechanism includes an engaging member, a push unit, and an electric driving motor unit. The engaging member is coupled co-rotatably to the spindle and is axially movable relative to the spindle from a first axial position, where the engaging member can be disengaged from the door handle, to a second axial position, where the engaging member engages the door handle such that rotation of the door handle results in corresponding rotation of the spindle. The push unit is driven by the motor unit so as to move the engaging member from the first axial position to the second axial position.
