Abstract
A ceiling fan blade snap-fit structure has a blade holder and a blade. The blade holder has a coupling seat. A rotating member is provided on the coupling seat. A plurality of posts are provided beside the rotating member. The blade has a coupling hole for the rotating member to pass therethrough. An engaging block is provided at either side of the coupling hole. An indentation is formed on a top of the engaging block. The engaging block has two slopes at two sides of the indentation. The slopes each extend downwardly toward the coupling hole. A bottom of the engaging block is formed with grooves for receiving the respective posts. When the rotating member passes through the coupling hole and the rotating member is rotated, two ends of the rotating member are moved along the corresponding slopes and engaged in the indentations of the respective engaging blocks.
