The technical scheme of the utility model, compare prior art, the implementation structure is simpler, can reduce the whole weight of fan blade, makes things convenient for the use of fan blade.

It should be noted that, in the technical scheme of the utility model, can realize in theory that blade 360 freely rotates to select required 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.
