Abstract: The present application provides an electric lock device, adopting a clutch mechanism composed of a driven gear and a turntable. The first side of the driven gear is provided with a mounting position for the turntable to be embedded, the sidewall of the mounting position is provided with an arc-shaped recess, and the outer sidewall of the turntable is provided with an arc-shaped bump corresponding to the arc-shaped recess. The central angle corresponding to the arc-shaped recess is denoted as ?, and the central angle corresponding to the arc-shaped bump is denoted as ?, then ? and ? satisfy: ????180°. Based on the above structure, there is a rotation virtual position greater than or equal to 180° between the driven gear and the turntable, that is, the gear can be rotated at least 180° regardless of the angle to which the gear rotates the turntable.
