Abstract: This invention publishes a kind of fan blade which can be assembled and disassembled quickly, including blade and blade bracket for ceiling fan, desk fan, pole fan, etc. In this invention, the blade and blade bracket are joined together by the inserting structure. During assembling, we only need to align the mounting holes with the elastic connectors and press downwards forcibly, and then the blade could be installed on the blade bracket securely. In this invention, screws are unnecessary for installing the blade on the blade bracket. The assembling is fast and the inserting structure is firm and reliable. When it comes to the necessity of disassembling the blade, only a press plate with matched holes is needed to press the elastic connectors and separate the blade from the blade bracket, which could greatly enhance the ease of use.
