ABSTRACT:
A Venetian blind includes a main body, a transmission mechanism, and a motorized drive mechanism. The motorized drive mechanism is operated to lift and lower the slats automatically. Thus, the Venetian blind does not need a lift cord, thereby preventing a child from being tangled by the lift cord so as to ensure the environmental safety of the house.
