The variable-pitch propeller comprises a propeller hub, a propeller blade assembly and a variable-pitch mechanism, the variable-pitch mechanism comprises a variable-pitch motor, a variable-pitch switch set, a switch triggering piece and a sliding block used for being connected with the propeller blade assembly, the variable-pitch switch set comprises a switch body matched with the switch triggering piece, a connecting rod is arranged between the switch triggering piece and the sliding block, and the connecting rod is connected with the propeller blade assembly. The switch triggering piece is in threaded connection with the connecting rod through the threaded section, and a nut abutting against the switch triggering piece is in threaded connection with the position, located on the threaded section, of the connecting rod. According to the scheme, the problem that in the prior art, the adjusting process of a variable pitch mechanism of a variable pitch propeller is complex is solved.
本发明涉及可变距的螺旋桨,包括桨毂、桨叶总成和变距机构,所述变距机构包括变距电机、变距开关组、开关触发件和用于连接桨叶总成的滑块,所述变距开关组包括与开关触发件配合的开关本体,所述开关触发件与滑块之间设置有连杆,所述开关触发件通过螺纹段与连杆螺纹连接,所述连杆上位于螺纹段处螺纹连接有与开关触发件相抵的螺母。本方案解决了现有技术中变距螺旋桨的变距机构的调节过程复杂的问题。
