SCREWLESS CURTAIN CONTROL ASSEMBLY
A screwless curtain control assembly is revealed. An assembly segment is disposed on one end of a bead chain base while first radial positioning parts and first axial positioning parts are arranged at the assembly segment alternately. A sleeve including second radial positioning parts and second axial positioning parts is mounted to the assembly segment of the bead chain base. Thereby the bead chain base and the sleeve are connected stably by the first radial positioning parts and the first axial positioning parts connected to and positioned by the second radial positioning parts and second axial positioning parts respectively. Thus both labor time for fastening screws and cost of the screws are saved. Therefore the screwless curtain control assembly meets the modern industry's requirement for high efficiency at low cost.
