Abstract
A plug-in transmission mechanism for a motor-driven blind is constructed to include a driving unit, two cord roll-up units controlled by the driving unit to lift/lower or tilt the slats of the motor-driven Venetian blind. Each cord roll-up unit includes an amplitude modulation wheel rotated by the driving unit to lift/lower the slats and bottom rail of the Venetian blind, a frequency modulation wheel for rotation with the amplitude modulation wheel to tilt the slats of the Venetian blind, a stop block adapted to limit the angle of rotation of the frequency modulation wheel, and a link supported on a spring in a longitudinal groove of the amplitude modulation wheel and detachably engaged into a notch of the frequency modulation wheel to control linkage between the amplitude modulation wheel and the frequency modulation wheel.
