Abstract
A fan blade mounting structure is constructed to include a first coupling unit fixedly located on the rotor of a fan motor assembly, the first coupling unit having a spring-supported hook and a control rod adapted to move the hook between the locking position and the unlocking position, and a second coupling unit fixedly located on a fan blade and adapted to secure the fan blade to the first coupling unit, the second coupling unit having a receiving hole for receiving the first coupling unit, a hook hole for receiving the hook when the hook moved to the locking position, and a spring-supported slide adapted to force the first coupling unit out of the second coupling unit when the hook moved to the unlocking position.
