Slat angle adjusting mechanism for window blind
A slat angle adjusting mechanism for a window blind includes a shell, a worm gear rotatably disposed in the shell, and a rotationally driving unit rotatably disposed in the shell and including combinable first and second rotationally driving shafts. The first rotationally driving shaft is located in the shell and has a worm portion engaged with the worm gear, a cone-shaped abutting portion and an embedding portion with non-circular cross-section, which are connected with the worm portion in order. A top end of the second rotationally driving shaft is located in the shell and has an axial hole with non-circular cross-section and two opposite fastening portions each formed at a terminal end thereof with a hooking claw. As a result, the first and second rotationally driving shafts are combinable by the consumer, preventing themselves and the slats from damage during packaging and transportation.
