<p>A blind control device of Venetian blind includes a retainer seat (1), a brake mechanism (2), a cord winding mechanism (3), and a ladder tape seat (4). The retainer seat (1) is arranged inside a head rail seat. The brake mechanism (2) includes a toothed disc (21), a spring (22), and a resilient plate (23). The brake mechanism (2) is operated in such a way that when the blind is stopped by being blocked by an external object during a lowering process, the spring (22) drives away a stop plate (213) of the toothed disc (21) the stop plate (213) and also causes rotation of the resilient plate (23) to engage a stop block of the ladder tape seat (4), thereby preventing a first reel disc (31) and a second reel disc (32) of the cord winding mechanism (3) from further rotation and thus preventing further unwinding of a lift cord (A) that may lead to undesired entangling.</p> |
