请一并结合图3和图5，所述安装座30固定于第一通孔23中，并与该桨叶20固定连接。所述按压部41自桨叶20上的第二开口232插入该第一通孔23，弹性件43抵持于所述按压部41的第一阻挡部413与安装座30之间，在该弹性件43的作用下，所述按压部41的按压端411部分的伸出于所述桨叶20上的第二开口232外。所述驱动轴10的第一端部11与所述安装座30的安装孔33连接，所述卡持臂13穿过该安装孔33，并收容于所述孔35内，所述套筒部36插入所述按压部41的第二容纳孔414内。

在一实施方式中，所述安装座30的第三端部31的第一容纳孔34的侧壁上凸伸形成有凸块，该凸块与所述滑槽416相配合，限制所述按压部41的滑动轨迹。在其他实施方式中，还可以通过在第一通孔23的内侧壁上设置阻挡部或者其他方式来限位所述按压部41在第一通孔23内的滑动路径和最大滑动位置。
如图5所示，所述锁定部40处于一锁定状态，所述按压部41的第二凹槽415与所述套筒部36的第二通孔38错开，所述卡持部42容纳于所述按压部41的第二通孔38中，卡持部42一端卡持于驱动轴10的卡持臂13的卡槽14中，另一端抵持于所述按压部41的第二容纳孔414的内侧壁417上，使所述卡持部42无法从卡槽14中脱离，从而实现对驱动轴10对的锁定。
请一并结合图3和图6，所述锁定部40处于一解锁状态，所述锁定部40的按压部41在外力的驱使下，沿所述桨叶20的第一通孔23向靠近驱动轴10的方向滑动至一预设位置时，按压部41的第二凹槽415与所述套筒部36的侧壁上的第二通孔38相连通，所述按压部41的第二容纳孔414的内侧所述卡持部42可以从卡槽14中脱离，弹性件43处于压缩状态。在解锁状态下，保持施加于所述按压部41上的外力，可将所述安装座30与驱动轴10相分离，例如，在本实施方式中，所述驱动轴10与安装座30之间通过螺纹配合的方式连接，只需要沿螺纹旋出方向旋转所述桨叶20，即可分离所述安装座30与驱动轴10。
在所述解锁状态下，撤除施加在按压部41上的外力，所述按压部41在弹性件43的作用下沿所述桨叶20的第一通孔23向远离驱动轴10的方向滑动，返回至图5所示的锁定状态。
在一实施方式中，所述安装座30和桨叶座21可以是一体成型的。
在其他实施方式中，所述锁定部40的按压部41仅需要可滑动的设置于所述桨叶20上，使所述套筒部36插入所述按压部41的第二容纳孔414内，在按压部41滑动至一预设位置时，按压部41的第二容纳孔414的内侧壁417上的第二凹槽415与所述套筒部36的侧壁上的第二通孔38相连通，容纳于所述第二通孔38内的卡持部42可以从卡槽14中脱离。
在其他实施方式中，所述锁定部40的按压部41可滑动的设置于所述桨叶20上，所述卡持部42可以为设置于所述按压部41上的可伸缩的卡销或者凸块，在该按压部41在桨叶20上滑动至一预设位置时，所述卡持部42的位置与所述驱动轴10的卡持臂13的卡槽14的位置相对应，从而卡入该卡槽中，实现对驱动轴10对的锁定。
在本实施方式中，通过在驱动轴10上设置具有卡槽14的卡持臂13，以及设置所述锁定部40，驱动轴10可以被锁定在安装座30上，即使在螺旋桨100发生较大震动幅度或者加速度变化较大的情况下，所述驱动轴10与安装座30也不会发生松脱现象。且本实施方式中的螺旋桨100拆卸结构简单，易于更换。本技术领域的普通技术人员应当认识到，以上的实施方式仅是用来说明本发明，而并非用作为对本发明的限定，只要在本发明的实质精神范围之内，对以上实施例所作的适当改变和变化都落在本发明要求保护的范围之内。
