A fan blade installation structure of a ceiling fan, the ceiling fan having at least one fan blade, at least one socket and at least one elastic member;
- the fan blade having a connecting end, the connecting end of the fan blade being formed with a blade hole;
- the socket having a space therein, an opening being formed on an outer side of the socket for the connecting end of the fan blade to be inserted into the space via the opening, a bottom of the socket having a through hole corresponding to the blade hole of the fan blade;
- the elastic member having a closed end and an open end, the closed end of the elastic member being fixed to a periphery of the socket, the open end of the elastic member being provided with a holding portion corresponding to the through hole and the blade hole, the open end of the elastic member elastically leaning against the holding portion, the holding portion having a guide surface corresponding to the connecting end of the fan blade, the holding portion being elastically moved in and out of the space via the through hole, the open end of the elastic member further having an operating portion outside the socket for a user to move the open end of the elastic member;
- wherein when the elastic member is in a normal state, the holding portion and the guide surface are located in the space, the guide surface faces the opening, and the guide surface extends in a direction away from the opening and the through hole for the guide surface to be pushed by the connecting end of the fan blade;
- wherein when the guide surface of the elastic member is pushed by the fan blade, the holding portion is moved away from the space;
- wherein when the fan blade is connected to the socket, the holding portion passes through the through hole and is engaged in the blade hole so that the fan blade is secured to the socket;
- wherein when the user operates the operating portion to move away from the space, the holding portion is moved away from the space,
- wherein the ceiling fan further has at least one bracket, at least one base and a motor, the motor has a rotor, the rotor is fixedly connected to the at least one bracket, and the at least one base is fixed below the at least one bracket so that the at least one socket is formed between the at least one base and the at least one bracket, wherein the elastic member further has a spring, a holding member and a shaft, the spring has the closed end and the open end, the base, the spring and the holding member are pivotally connected to the shaft, the closed end of the elastic member is fixed below the base, the holding member is disposed on one side of the open end of the elastic member adjacent to the through hole so that the open end of the elastic member leans against the holding member, the holding member has the holding portion extending toward the space, and the holding member extends downward and outward to form the operating portion.
