[0053] The working principle and beneficial effects of this embodiment are as follows: by fixing the fan frame 1 and the fan in use, the wires connected to the fan are introduced into the fan through the wire outlet slot 2, thereby ensuring that the wires can be laid out in parallel, ensuring the beauty of the product and avoiding the risk of loose wires, warping and interfering with the fan blades;

[0054] The wire is led out of the fan frame 1 from the wire outlet trough 2, and a wire clamp 4 is used at the outer end of the wire outlet trough 3 to limit the wire to prevent the wire from loosening and curling;

[0055] The wire outlet slot 3 of the fan outer frame 1 is arranged on the back of the fan outer frame 1. The wire is routed through the wire outlet slot 2, and there is no interference between the wire and the bottom of the fan blade, which effectively avoids the loosening and warping of the wire during the operation of the fan in the prior art, thereby improving safety and practicality.
