ABSTRACT:
The invention relates to a fast-positioning device for assembling blade brackets to a motor housing of a ceiling fan. The motor housing has its bottom provided with plural locations located around its circumference, which are respectively extended downward with at least two restricting plates having a long side aligned as a beam radiated from the center of the motor housing. Each location of the restricting plates is to be connected with a blade bracket, which has a connecting portion extended with at least one positioning projection for being moved horizontally to engage with the restricting plates. As good vision is kept during installation, the blade brackets can be easily assembled on the motor housing and the relative locations to be positioned are in a line.
