[0019] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention. The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] For example, see Figures 1 to 3 As shown: A fan blade installation structure on a floor fan includes a turntable 10 connected to the motor shaft of the floor fan and fan blades 11. The fan blades 11 are installed on the turntable 10 at equal intervals through the connecting parts thereon and are linked thereto. The installation structure of the fan blades 11 and the turntable 10 is as follows: it also includes an end cap 12, and a groove 13 is opened on the end surface of the turntable 10, that is, the groove 13 runs through the front surface of the turntable 10, and the number of grooves 13 is the same as the number of fan blades 11; a clamping block 14 is provided on the connecting portion of the fan blade 11, and the clamping block 14 is embedded in the groove 13 from the front surface of the turntable 10 to achieve the clamping effect. At the same time, the clamping block 14 and the inner circumference of the groove 13 form a limiting structure that restricts the fan blade 11 from escaping from the circumference of the turntable 10. The limiting structure is as follows: a stopper 16 is provided on the clamping block 14, and a stopper 2 17 is provided in the groove 13. The stopper 16 and the stopper 2 17 are mutually clamped; this can prevent the fan blade 11 from escaping from the groove 13 during rotation. An opening 15 is opened on the groove 13 and runs through the circumference of the turntable 10. The opening 15 is used to allow the connecting portion of the fan blade 11 to pass through. The end cap 12 covers the turntable 10 to prevent the block 14 from being dislodged from the end surface of the turntable 10. The cover structure is as follows: an inner retaining strip 18 is provided on the inner circumference of the end cap 12, and an outer retaining strip 19 is provided on the outer circumference of the turntable 10. The inner retaining strip 18 and the outer retaining strip 19 are mutually engaged. When the end cap 12 is closed, its covering surface abuts against the connection portion of the fan blade 11 to prevent the fan blade 11 from loosening.

[0021] See Figures 4 to 7As shown, a floor fan includes a motor 20, a support rod 21, a base 22, and a fan blade mounting structure. The fan blade mounting structure is connected to the rotating shaft on the motor 20. When the rotating shaft rotates, the fan blade mounting structure is linked with it (the fan blade mounting structure has been described in detail above and will not be elaborated here). The motor 20 is mounted on the support rod 21, and the bottom of the support rod 21 is plugged into the base 22. The base 22 is composed of two detachable left and right halves 221 and 222. The left and right halves 221 and 222 are separated by a socket 23 and a latch 24 provided on the side of the left half 221, and an insert block 25 and a hook 26 provided on the side of the right half 222. The insert block 25 is inserted into the socket 23, and the hook 26 is engaged with the latch 24. This structure allows the base 22 to be disassembled during transportation, saving packaging costs while also improving transportation efficiency. An inner base 30 is provided at the bottom of the base 22. The inner base 30 is composed of two detachable inner left halves 301 and inner right halves 302. A T-shaped bayonet 31 is provided on the side of the inner left halves 301, and a T-shaped block 32 is provided on the side of the inner right halves 302. The T-shaped block 32 is engaged with the T-shaped bayonet 31. The inner base 30 enhances the support of the base 22, making it more stable.
