In addition, the left and right swing driving structure 100 of the fan has a simple structure, which can effectively simplify the installation operation and improve the installation efficiency, and does not require gear transmission, which can effectively avoid the fan from shaking in the process of driving the fan to swing.

[0026] like Figure 1As shown, the driving assembly 30 also includes a plurality of locking members 32 for fixing the driving motor 31 to the rotating frame 20, and the driving motor 31 is provided with a plurality of mounting holes 312 for the locking members 32 to pass through. The rotating frame 20 is provided with a plurality of fixing holes 21, and the locking members 32 pass through the mounting holes 312 of the driving motor 31 and are locked in the fixing holes 21 of the rotating frame 20, so as to fix the driving motor 31 to the rotating frame 20.
