为了解决上述技术问题，本申请实施例还提供以下技术方案：
一种无人飞行器，包括机身、机臂以及如上所述的动力组件，所述动力组件与所述机臂连接。
本申请提供的无人飞行器及其动力组件、螺旋桨、螺旋桨底座组件具有如下优点：
1.本申请提供的螺旋桨底座组件，当安装螺旋桨时，按键开关轴向滑动地设置在固定座上，并抵持螺旋桨上朝向固定座凸出的钩形卡件卡持在收容空间内，进而通过钩形卡件的卡持作用，来实现螺旋桨在螺旋桨底座组件上的固定连接；当拆卸螺旋桨时，按压按键开关，钩形卡件脱离收容空间，此时钩形卡件与固定座不再卡持连接，即实现了对螺旋桨的拆卸，由于螺旋桨在螺旋桨底座组件上的安装仅仅需要通过对按键开关的单向外力按压就可实现，进而在实现快速拆装的同时，其操作更加简单、方便。
2.本申请提供的螺旋桨底座组件，由于按键本体滑动地设置在第一通孔中，并且按键本体的外表面对应于收容空间的位置向外凸伸形成有环状 的导引斜面，导引斜面沿着外力按压的方向轴径逐渐增大，进而当螺旋桨的钩形卡件滑动地伸入第一通孔中时，沿着导引斜面逐渐靠近收容空间，直至最终滑入收容空间中，并被按键本体的外周表面抵持，而无法退出收容空间。
3.本申请提供的螺旋桨底座组件，通过按键本体的一端的外表面向外凸伸形成有环状的凸台，凸台的外径大于所述第一通孔的孔径，进而使得按键本体安装在固定座上时，无法穿过第一通孔，进而保证了按键本体位置的稳定性以及功能的正常实现。
4.本申请提供的螺旋桨底座组件，通过在按键本体的外表面位于导引斜面和凸台之间的部分向外凸伸形成有抵顶面，抵顶面滑动地收容于第一通孔中，并抵持钩形卡件卡持在收容空间中，进而使得按键开关与钩形卡件的接触为线接触、甚至是面接触，进而避免了仅仅通过导引斜面抵持时，钩形卡件与导引斜面因接触面过小导致的磨损加快的情况产生。
5.本申请提的螺旋桨底座组件，通过收容空间内设置有弹性件，钩形卡件收容在收容空间的部分抵持并压缩弹性件，进而当外力按压按键开关时，一方面按键开关给予钩形卡件足够的退回空间，另一方面弹性件对钩形卡件施加足够的退出推力，以保证按键开关正常退出收容空间。
6.本申请提供的螺旋桨，由于座体朝向螺旋桨底座组件的一侧成型有多个凸出座体的钩形卡件，钩形卡件与螺旋桨底座组件中的收容空间相配合，以使座体可拆卸地固定连接在螺旋桨底座组件上，进而通过钩形卡件与收容空间之间的配合，能够有效的实现了螺旋桨的快速拆卸，同时采用钩形设计，使得螺旋桨连接结构简单、加工容易、稳定性好。
7.本申请提供的螺旋桨，由于座体朝向螺旋桨底座组件的一侧凹陷形成有一收容槽；收容槽的槽底沿轴向开设有贯穿座体的第二通孔；多个钩形卡件成型于收容槽的槽底壁，并等角度的间隔设置在第二通孔的外围，进而增加了钩形卡件的长度以及变形容纳空间，以减小其在滑动过程中产生的形变，从而提高了钩形卡件使用寿命。
8.本申请提供的动力组件，由于包括上述的螺旋桨底座组件及对应的螺旋桨，因此具备上述任一项所述的优点；同时，钩形卡件与收容空间的数量对应，且分别设置在固定座及座体的相配合的对应位置上，按键开关在不受外力按压状态时，抵持钩形卡件收容在收容空间内，进而使得该动力组件仅仅需要控制钩形卡件在收容空间的卡持状态，即可实现螺旋桨在 螺旋桨底座组件上的快速安装，在结构简单的同时，带来了操作更加简单、方便的效果。
9.本申请提供的无人飞行器，由于具有上述的动力组件，同时该动力组件包括上述的螺旋桨底座组件以及螺旋桨，因此具有上述任一项所述的优点。

此外，下面所描述的本申请不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
如图1至图3所示，为本申请一实施例提供的动力组件的示意图，其包括螺旋桨底座组件100、螺旋桨300以及驱动装置200。所述螺旋桨300可拆卸地固定至所述螺旋桨底座组件100，所述螺旋桨底座组件100固定安装于所述驱动装置200，所述驱动装置200与所述螺旋桨300连接，用于给所述螺旋桨300的旋转提供动力。
其中，螺旋桨300包括座体301和周向均匀分布设置在座体301上的至少两个桨叶303，座体301朝向螺旋桨底座组件100的一侧成型有多个凸出座体301的钩形卡件302，所述多个钩形卡件302收容在螺旋桨底座组件100的固定座1的收容空间11中，以使座体301可拆卸的固定连接在螺旋桨底座组件100上。
螺旋桨底座组件100包括固定座1按键开关2，固定座1固定连接在驱动装置200的主体201上，所述固定座1上设置有多个收容所述钩形卡件302的收容空间。按键开关2轴向滑动地穿设在固定座1上，具有适于按触的按键本体21。其中，当所述按键开关2不受外力按压时，抵持所述钩形卡件302而使所述钩形卡件302卡持在所述收容空间11内；当所述按键开关2受外力按压时，所述钩形卡件302脱离所述收容空间11。
钩形卡件302与收容空间11的数量对应，分别设置在所述固定座1及所述座体301的相配合的对应位置上。按键开关2在不受外力按压时，抵持钩形卡件302以使得所述钩形卡件302收容并卡持在收容空间11内；弹按键开关2在受外力按压时，钩形卡件302脱离收容空间11。螺旋桨底座组件100还包括复位件22，在所述按键开关2受外力按压而相对于所述固定座1的轴向滑动时，所述复位件22对所述按键开关2施加回复力。在本 实施例中，所述复位件23为弹簧。
对于上述动力组件，在安装所螺旋桨300时，按键开关2轴向滑动地设置在固定座1上，并抵持螺旋桨300上的钩形卡件302以使得所述钩形卡件302收容并卡持在收容空间11内，进而通过钩形卡件的卡持作用，来实现螺旋桨300在螺旋桨底座组件100上的固定连接；在拆卸所螺旋桨300时，按压弹性滑块2，钩形卡件302脱离收容空间11，此时钩形卡件302与固定座1不再卡持连接，即实现了对螺旋桨300的拆卸，由于螺旋桨300在螺旋桨底座组件100上的安装仅仅需要通过对弹性滑块2的单向外力按压就可实现，进而在实现快速拆装的同时，其操作更加简单、方便；同时采用钩形设计，使得螺旋桨300连接结构简单、加工容易、稳定性好。
具体地，按键本体21为圆柱形，按键本体21朝向复位件22的一端的外表面向外凸伸形成有环状的凸台212；固定座1及座体301沿轴向分别开设有轴向对齐的贯穿的第一通孔12和第二通孔3012；按键本体21滑动地设置在第一通孔12和第二通孔3012中，凸台212的外径大于所述第一通孔12的孔径，进而使得按键本体21在复位件22释放状态下抵持固定座1的与座体301相背的端面，而不会从固定座1中脱离，保证了弹性滑块2组装的稳定性以及功能的实现。
其中，如图4和图5所示，按键本体21的外表面对应于所述收容空间11的位置向外凸伸形成有环状的导引斜面211，所述导引斜面211沿着外力按压的方向轴径逐渐增大。按键本体21的外表面位于导引斜面211和按键本体21之间的部分向外凸伸形成有抵顶面213，导引斜面211和抵顶面213可滑动地收容于第一通孔12中；第一通孔12的孔壁上向内凹设有所述收容空间11，如图3所示。
当钩形卡件302连接在固定座1上时，钩形卡件302的卡钩部分3021沿导引斜面211滑动地伸入第一通孔12中，沿着导引斜面211逐渐靠近收容空间11，直至最终滑入收容空间11中，通过抵顶面213的抵持作用卡持在收容空间11中，并且被按键本体2的外周表面抵持，而无法退出收容空间。具体地，钩形卡件302围绕按键本体21插设在所述第一通孔12的中，并沿导引斜面211滑入收容空间11内，此时钩形卡件302的卡钩部分3021在沿着第一通孔12的孔壁向下滑动的过程中，受到导引斜面211对其施加的作用力，进而产生向外扩张的趋势，当卡钩部分3021滑动到收容空间11位置时，钩形卡件302受到导引斜面211的挤压，以使卡钩部分3021卡入 收容空间11；同时由于抵顶面213与钩形卡件302采用线接触，甚至是面接触，进而降低了导引斜面211和卡钩部分3021的磨损，从而增加了该动力组件的使用寿命。
作为可选的实施方式，所述收容空间11内设置有弹性件13，所述钩形卡件302收容在所述收容空间11的卡钩部分3021抵持并压缩所述弹性件13，弹性件13包括弹簧131和弹性滑块132，弹簧131设置在弹性滑块132和收容空间11的内壁之间；钩形卡件302的卡钩部分3021与弹性滑块132相配合，并抵持弹性滑块132以使得弹簧131压缩，进而通过弹簧131对弹性滑块132的弹力作用，实现了弹性件13对卡钩部分3021的抵持功能。在本实施方式中，复位件22同样为弹簧131。
为了使得座体301在固定座1上的安装更加方便、准确，往往座体301朝向固定座1的一侧还成型有至少一桨叶304；固定座1的第一通孔12的内壁对应于桨叶304向内凹进设置有至少一导向槽14，桨叶304滑动地设置在导向槽14中，如图3所示。
动力组件在使用的过程中，由于钩形卡件302和桨叶304不断的受到力的作用而发生形变，进而其很容易损坏而使得动力组件失去其快拆功能，因此往往要求提高钩形卡件302和桨叶304的使用寿命以保证动力组件功能的实现。对此，如图3所示，座体301朝向螺旋桨底座组件100的一侧凹陷形成有一收容槽3011；多个所述钩形卡件302成型于收容槽3011的槽底壁，并伸出收容槽3011，等角度地间隔设置在所述第二通孔3012的外围，进而增加了钩形卡件302和桨叶304的长度，以减小其在滑动过程中产生的形变，从而提高了钩形卡件302和桨叶304的使用寿命。
除此之外，座体301朝向固定座1的一侧成型有至少一导向柱304，所述导向柱304滑动地设置在上述导向槽14中。多个导向柱304和多个钩形卡件302等角度交替间隔的围绕设置在第二通孔3012的外围，并伸出所述收容槽3011，进而使得螺旋桨300在螺旋桨底座组件100上的受力平衡，保证了螺旋桨300在使用过程中无人飞行器飞行的稳定性。
在动力组件使用的过程中，除了要保证螺旋桨300与固定座1周向固定，往往还需要使得弹性滑块2相对于座体301在周向上相对固定，以保证了两者之间组装的稳定性，对此，按键本体21插入座体301的第二通孔3012中的外表面向外突出形成有异形突起214，第二通孔3012朝向固定座1的一侧对应于异形突起214设置有异形凹槽(图未示)，异形突起214滑 动地设置在异形凹槽中，进而使得异形突起214和异形凹槽之间异形配合，从而保证了弹性滑块2相对于座体301在周向上相对固定。
在驱动螺旋桨300转动的过程中，作为可选的实施方式，驱动装置200为一旋转电机(图中未标示)，旋转电机的输出轴固定连接有主体201，主体201上设置有一凸伸的驱动轴202，弹性滑块2和复位件22活动的套设在驱动轴202上，复位件22推动弹性滑块2以抵持钩形卡件302的卡钩部分3021卡持在收容空间11内，进而复位件22能够稳定的对钩形卡件302施加抵持力，保证了螺旋桨300与固定座1之间的组装稳定性。同时，固定座1通过连接件400固定安装在主体201上，在本实施方式中，连接件400为螺丝，进而可以通过控制旋转电机的输出轴的转动，以驱动主体201旋转，使得主体201驱动固定座1旋转并带动卡持在固定座1中的钩形卡件302轴向旋转，从而实现了螺旋桨300同轴转动。
作为变形的实施方式，所述驱动装置200还可以为旋转气缸等具有旋转输出动力的机构，在此不再加以一一列举。
本申请实施还提供一种无人飞行器(图未示)，包括机身、机臂以及如上实施例中记载的动力组件，所述动力组件与所述机臂连接，用于给所述无人飞行器提供飞行动力。
上述无人飞行器，由于采用了上述动力组件，因此具有上述实施例中所述的优点。
最后应说明的是：以上实施例仅用以说明本申请的技术方案，而非对其限制；在本申请的思路下，以上实施例或者不同实施例中的技术特征之间也可以进行组合，步骤可以以任意顺序实现，并存在如上所述的本申请的不同方面的许多其它变化，为了简明，它们没有在细节中提供；尽管参照前述实施例对本申请进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例技术方案的范围。
