[0026] The present invention will now be further described with reference to the accompanying drawings.

[0027] According to the appendix Figures 1 to 4 As shown, the split fan blade of this utility model includes a combined fan blade, which includes a rotating connector 1 connected to the motor shaft and several fan blades 2. The side wall of the rotating connector 1 has several mounting holes 11 evenly distributed around the axis. The fan blades 2 are respectively mounted on the rotating connector 1 through the mounting holes 11. The rotating connector 1 is provided with a fixing connector for locking the fan blades 2 on the rotating connector 1.

[0028] By rotating the connector 1 and cooperating with its mounting hole 11 and the fixed connector, several fan blades 2 can be assembled onto the rotating connector 1 through the mounting hole 11. The modular assembly structure is easy to assemble and disassemble, easy to package and transport, and reduces transportation costs.

[0029] Reference Figures 1 to 4 As shown in the figure, further detailed, the rotating connector 1 is provided with a support tilting platform 12 for tilting and positioning the fan blade 2, and the fixed connector is provided on the fan blade 2 and is detachably connected to the support tilting platform 12.

[0030] The inclined support platform 12 facilitates quick assembly and disassembly of the fan blades 2, making operation convenient. It also increases the contact area between the fan blades 2 and the rotating connecting piece 1, thereby enhancing structural stability.

[0031] Furthermore, the fixed connector includes a screw 3, and the support tilting platform 12 is provided with a screw hole 4. The screw 3 passes through the fan blade 2 and is threadedly connected to the screw hole 4.

[0032] The above-mentioned fixed connecting parts use screws 3 and screw holes 4 to strengthen the connection between the fan blade 2 and the rotating connecting parts 1, prevent the fan blade 2 and the rotating connecting parts 1 from loosening during high-speed operation, and extend the service life of the product.

[0033] In addition, the fixed connector also includes a snap-fit ​​block 5 for facilitating the sliding of the fan blade 2 from the mounting hole 11 onto the support tilting platform 12 and fixing it to the support tilting platform 12. The snap-fit ​​block 5 is distributed on the side of the support tilting platform 12.

[0034] The use of snap-fit ​​block 5 further enhances the sturdiness of the fan blade 2 assembly and reduces the occurrence of loosening.

[0035] Furthermore, the rotating connector 1 is provided with a locking cover, which covers the end of the fixed rotating connector 1 and is fitted with locking pins that are locked onto the fixed rotating connector 1.

[0036] The combination of the locking cap and the locking pin not only strengthens the connection stability but also enhances the product's aesthetics.

[0037] Reference Figures 5 to 9 As shown, the second embodiment differs from the above in that: the rotating connector 1 is provided with a support platform 13, the end of the fan blade 2 is provided with a support connection part 21 that is obliquely assembled on the rotating connector 1, the support connection part 21 passes through the mounting hole 11 and is connected to the support platform 13, and the fixed connector is provided on the support platform 13 and is detachably connected to the support connection part 21.

[0038] With the structural cooperation between the support platform 13 and the support connection part 21, during assembly and disassembly, the support connection part 21 can slide onto or detach from the support platform 13 through the mounting hole 11. The split structure is convenient to operate, easy to package and transport, and has a large contact area, which enhances the stability of the connection.

[0039] The fixed connector includes a fixed buckle 8, which is disposed on the support platform 13, and the support connection part 21 is provided with a snap-fit ​​hole 7 adapted to the fixed buckle 8 for fastening.

[0040] That is, when the support connection part 21 is slidably mounted in a specific position on the support platform 13, the snap-fit ​​hole 7 is then snapped onto the fixing buckle 8, locking the support connection part 21 onto the support platform 13, thereby improving the disassembly and assembly efficiency of the fan blade 2, reducing the use of parts, and lowering manufacturing costs.

[0041] During this period, the fixed connector also includes a locking cover 9, which is integrally connected to a threaded post 91, and the rotating connector 1 has a connecting hole 6 for threaded connection with the threaded post 91.

[0042] With the locking cover 9, during disassembly and assembly, simply rotate the locking cover 9 to lock the threaded post 91 onto the connecting hole 6, thereby locking the fan blade 2 onto the rotating connector 1. The structure is stable, reliable, practical, and aesthetically pleasing.
