When the hub 101 is installed in the accommodating space 22, the length The direction is consistent with the second direction.

Specifically, the preset range may be an included angle range of approximately 90 degrees, that is, the second direction and the first direction are substantially perpendicular. When the hub 101 is installed in the accommodating space 22, since the length direction of the hub 101 is consistent with the second direction, the length of the hub 101 in the accommodating space 22 can be increased, and further, the hub can be lifted.

In order to avoid incorrect installation of the propeller rotating clockwise and counterclockwise.

Specifically, since the size of the limiting shaft 24 corresponding to the first mounting seat is different from the size of the limiting shaft 24 corresponding to the second mounting seat, the size of the limiting shaft 24 is the same as that of the propeller hub 101. The size of the limiting hole is compatible, that is, the size of the limiting hole on the hub of the propeller rotating clockwise and the size of the limiting hole on the hub of the propeller rotating counterclockwise are also Different, in this way, when the limit shaft 24 is installed to the limit hole on the hub of the propeller that rotates clockwise, or the limit shaft 24 is installed on the hub of the propeller that rotates counterclockwise When the limit hole is used, an incorrect installation situation where the limit shaft 24 does not fit the limit hole can be found in time, so as to avoid incorrect installation of the propeller rotating clockwise or counterclockwise.
