In an embodiment of the present invention, a bearing is mounted on each suspension rod 401, and the driving mechanism is mounted on one of two adjacent bearings, so that the stability of mounting the driving mechanism can be improved by the arrangement of the bearings, and the stability of rotation of the wing 101 can be improved.
