Abstract
An electric door lock includes a transmission wheel driven by a motor and incorporating a spring with a driving end to drive a driven wheel. The transmission wheel and the driven wheel are rotatably sleeved around an inner drive tube connected to an inner handle. A spindle is inserted into the inner drive tube and has an operating end exposed from the inner handle. The driven wheel is connected integrally to the spindle for rotation. Preferably, a coupling piece extends through an arc-shaped slot in the inner drive tube and interconnects the driven wheel and the spindle.
