The vane 30 is rotatably installed between the first end plate 10 and the second end plate 20, and a first end of the vane 30 adjacent to the first end plate 10 is provided with a gear member 31. The rack member 40 is movably disposed on the first end plate 10, and the rack member 40 is movable and cooperates with the gear member 31 to rotate the blade 30.

By applying the technical scheme of the invention, the movable gear condition 40 drives the gear piece 31 to rotate, so that the blades 30 can rotate, the orientation of the blades 30 can be adjusted, the gap can be adjusted, and different air outlet directions and air volume sizes can be obtained, thereby meeting different use requirements. Compared with the prior art, the technical scheme of the invention has the advantages that the implementation structure is simpler, the overall weight of the fan blade can be reduced, and the use of the fan blade is convenient.

In the technical solution of the present invention, it is theoretically possible to realize a 360 ° free rotation of the blades, thereby selecting a desired wind direction.

As shown in fig. 2 and 3, in the solution of the present embodiment, there are a plurality of vanes 30, the plurality of vanes 30 are arranged in a ring shape, and the rack member 40 is a ring-shaped rack which is engaged with the plurality of gear members 31, respectively. When the device is used, the annular rack is only required to be operated to rotate, the blades 30 can be driven to rotate together, and then the orientation and the gap of the blades 30 are adjusted. As other alternative embodiments, a plurality of straight racks may be used to achieve the above-described effects.

As shown in fig. 2, in the solution of the present embodiment, a second end of the vane 30 close to the second end plate 20 is provided with a rotating shaft 32, the vane 30 is rotatably mounted on the second end plate 20 through the rotating shaft 32, and the rotation of the vane 30 can be smoother through the rotating shaft 32.

As shown in fig. 3, as a preferred embodiment, an operating portion 41 is formed on the rack member 40, and the operating portion 41 is used for operating the rotation of the rack member 40. In use, the blade 30 is rotated by manually operating the operating portion 41 to rotate the rack member 40. More preferably, the fan blade further comprises a fastening member 42, and the fastening member 42 is disposed on the operating portion 41 and is used for fixing the operating portion 41 on the first end plate 10. When it is necessary to adjust the rotation of the blade 30, the fastener 42 is loosened, and the rack member 40 can be rotated by the operating portion 41; after the adjustment blade 30 is rotated, the tooth members 40 are fixed by tightening the fasteners 42 to the first end plate 10, thereby maintaining the attitude of the blade 30.
