ABSTRACT:
A connecting assembly of a ceiling fan for fixing blades includes a connecting device mounted to a motor of the ceiling fan and a seat having multiple grooves radially defined in a bottom of the seat. The grooves extend to an outer periphery of the seat. A channel is laterally defined in one side of each of the multiple grooves and laterally communicates with the groove. A buckle is movably received in a corresponding one of the channels. A bracket has a first end inserted into a corresponding one of the multiple grooves and a second end adapted to connected to a blade of the ceiling fan. Each bracket has an indentation laterally defined for selectively partially receiving the buckle to hold the bracket in place when the first end of the bracket is inserted into the corresponding one of the multiple grooves in the seat.
