  • Patent number: 10935043
    Abstract: An assembly of a blade assembly bracket and a blade of a ceiling fan includes a blade assembly bracket, an adaptor, and a fan blade. The adaptor is pivoted to the blade assembly bracket, and the fan blade is pivoted to the adaptor. When the adaptor is pivoted relative to the blade assembly bracket, the adaptor can drive the rotatable holder simultaneously to switch a position of the fan blade between an initial position and a rotational position, so as to change an inclination angle of the fan blade, and make the fan blade unfold outwardly. When the operation of the ceil fan is stopped, the adaptor is operated reversely to make the fan blade fold from the outwardly-unfolded state.
