    摘要: A slat angle adjustment mechanism adapted for use with slats of a Venetian blind includes a body shell and a transmission unit. The transmission unit includes a transmission gear set and a retractable member. The transmission gear set has a gear and a screw. A position-limiting hole of the gear corresponds in position to a second through hole of the body shell. The retractable member connects to the extendible segment of the screw and undergoes reciprocating motion along the extendible segment of the screw. Pulling the retractable member from an initial first position of the extendible segment of the screw to a second position of the extendible segment of the screw allows a rib of the body shell to be confined to a limiting portion of the retractable member. Therefore, the slat angle adjustment mechanism is capable of extension, retraction, engagement and fixation.
