The invention relates to a variable pitch propeller, in particular to a blade assembly for a variable pitch propeller, which comprises a blade body and a blade support, the blade support is provided with an accommodating cavity used for being connected and matched with the root of the blade body, and the blade support is provided with a mounting part used for mounting an eccentric pin. The mounting part protrudes towards the interior of the containing cavity, and the root of the paddle body is provided with a combination section matched with the containing cavity in shape. According to the scheme, the problem that in the prior art, after a fixed-wing unmanned aerial vehicle using a variable pitch propeller is maintained, the flight height upper limit is prone to generating serious deviation is solved.

    本发明涉及变距螺旋桨,具体为一种变距螺旋桨用桨叶总成,包括桨叶本体和桨叶支座,所述桨叶支座设置有用于与桨叶本体的根部进行连接配合的容纳腔,所述桨叶支座上设置有用于安装偏心销的安装部,所述安装部朝向容纳腔的内部凸出设置,所述桨叶本体的根部具有与容纳腔的形状匹配的结合段。本方案解决了现有技术中使用变距螺旋桨的固定翼无人机在进行维护后容易出现飞行高度上限产生严重偏差的问题。
