[0019] Furthermore, the angle between the elastic portion and the locking portion is greater than 0 and less than 180°.

[0020] Furthermore, the angle between the elastic portion and the locking portion is greater than 0 and less than 90°.

[0021] The elastic part can easily exert a force on the locking part in the opposite direction of the elastic force, thereby ensuring that the locking part and the locking buckle part are against each other, thereby improving the firmness of the fan blade installation.

[0022] Furthermore, the elastic part is a long elastic arm, the elastic part is S-shaped, and the locking part is a slot with a root side surface recessed inwardly.
