Abstract:
A safe curtain control assembly which does not require screws to assemble is revealed. The safe curtain control assembly includes a stopping portion located on a wall of a cavity of a base forming a raised structure, and a recessed area is formed by the wall of the cavity and the stopping portion. A sleeve, an elastic member and a drive member are mounted within the cavity of the base in turn. A second stopping flange of the drive member is positioned in the recessed area between the wall of the cavity and the stopping portion for preventing the sleeve, the elastic member, and the drive member assembled from being released. Thereby the base, the sleeve, the elastic member and the drive member are secured firmly without screws so as to save time and cost for each assembly.
