请参阅图2至图4，缺口136包括靠近基座顶面112的缺口侧面1362，缺口侧面1362和安装槽侧面132相交形成的夹角A为锐角，即，0°<A<90°。进一步地，在一些例子中，夹角A的角度为大于或者等于45度而小于90度(即(45°≤A<90°))，例如夹角A可以为45度、50度、55度、60度、65度、70度、75度、85度、88度、无限接近90度等等。在另一些例子中，缺口侧面1362和安装槽侧面132垂直，即夹角A也可为90度。在又一些例子中，缺口侧面1362和安装槽侧面132相交形成的夹角A为钝角，即夹角A大于90度且小于180度。本实施方式中，缺口侧面1362为平面；在其它一些例子中，缺口侧面1362为曲面，曲面的曲率中心位于安装槽13内。
请一并参阅图1及图2，基座11上还开设有收容槽14，收容槽14位于安装槽13相对的两侧。收容槽14贯穿基座顶面112和基座侧面116相对的两侧，收容槽14与安装槽13垂直并经过基座11的中心与安装槽13连通，也即是，收容槽14的数量为两个，安装槽13和两个收容槽14大致呈“十”字形。在其他实施方式中，收容槽14也可以不与安装槽13垂直，也即，收容槽14与安装槽13形成夹角；或者收容槽14 也可以不经过基座11的中心。
请一并参阅图2及图3，第二连接器20包括连接本体21、设置在连接本体21上的第二结合件22、及连接杆23。
连接本体21包括连接主体212和两个连接凸出部214。连接主体212包括主体侧面2122和主体曲面2124，主体侧面2122和主体曲面2124各有两个且两两相对。两个主体侧面2122平行相对且分别连接一个主体曲面2124，两个主体曲面2124的外形与基座11的外形相匹配，使得第二连接器20安装在第一连接器10上时，主体曲面2124与基座侧面116均为圆柱体结构的外圆周面的一部分，此时，第二连接器20安装在第一连接器10后的结构的外轮廓能接近圆周。每个主体侧面2122的一端延伸形成一个连接凸出部214。连接本体21安装在安装槽13中时，两个连接凸出部214的侧面分别抵持两个安装槽侧面132，两个主体侧面2122分别与两个安装槽侧面132相对。
请参阅图1至图4，第二结合件22为弹性凸起24，弹性凸起24包括相连接的弹性本体242及凸起本体244。当第二连接器20安装在第一连接器10上时，弹性凸起24卡设在缺口136内，弹性凸起24与主体侧面2122相间隔以形成间隙246。
具体地，弹性本体242包括固定端2424、与固定端2424相背的自由端2422、及弹性本体侧面2426。固定端2424设置在连接本体21的连接凸出部214上，自由端2422与连接本体21的主体侧面2122之间形成有间隙246，间隙246自自由端2422延伸至固定端2424，自由端2422在受到朝间隙246一侧的力时能够朝间隙246一侧弯曲。两个连接凸出部214均设置有弹性凸起24，也即是，弹性凸起24有两个，两个弹性凸起24对应两个主体侧面2122设置，并与两个安装槽侧面132相对。弹性本体侧面2426位于弹性本体242远离主体侧面2122的一侧，也即，弹性本体侧面2426与安装槽侧面132相对。当第二连接器20安装在第一连接器10上时，弹性本体侧面2426抵持在对应的安装槽侧面132上。
请参阅图3和图4，弹性本体242的远离主体侧面2122的侧面(即弹性本体侧面2426)上凸出形成有凸起本体244，凸起本体244与缺口136相匹配，也即是说，弹性本体242和凸起本体244共同形成第二结合件22。当第一连接器10和第二连接器20结合时，弹性本体242收容在安装槽13内，凸起本体244自适应变形卡设在缺口136内，也即是第一结合件12和第二结合件22结合。凸起本体244垂直于弹性本体侧面2426方向的最大高度H1小于间隙246的宽度W1，以保证弹性本体242具有足够的移动空间可以而从缺口136内脱离。凸起本体244可以是矩形、锥形或者其它形状等等，在本实施方式中，凸起本体244大致呈锥形。
凸起本体244包括凸起侧面2442、凸起外侧面2444、及凸起连接面2446。凸起侧 面2442位于远离固定端2424的一侧。凸起外侧面2444自凸起侧面2442朝固定端2424的方向延伸，本实施方式中，凸起外侧面2444与弹性本体侧面2426平行。凸起连接面2446为过渡连接凸起外侧面2444和弹性本体侧面2426的连接面，在一个实施方式中，凸起连接面2446可为曲面。在另一实施方式中，也可以采用平面过渡连接凸起外侧面2444和弹性本体侧面2426，也即，凸起连接面2446可为平面。在另一个实施方式中，凸起外侧面2444可省略，此时，凸起连接面2446直接连接凸起侧面2442与弹性本体侧面2426，且凸起本体244自固定端2424至自由端2422的方向上的高度(凸起本体244垂直于弹性本体侧面2426方向的尺寸)逐渐增大。当第二连接器20安装在第一连接器10上时，可以是：凸起本体244的全部伸入第一连接器10的缺口136中；或者，凸起本体244的一部分收容在安装槽13内，凸起本体244的另一部分从安装槽13伸入至第一连接器10的缺口136中。
凸起本体244的高度H1为[0.5，1]毫米，例如可以是0.5毫米、0.55毫米、0.66毫米、0.68毫米、0.72毫米、0.8毫米、0.88毫米、0.95毫米、1毫米等等。当凸起本体244的高度H1小于0.5毫米时，会造成凸起本体244卡扣不牢固，或者需要更高强度的材料才能卡扣牢固，当凸起本体244的高度H1大于1毫米时，会增大间隙246的宽度，进而增大第二连接器20的体积。而凸起本体244的高度H1为[0.5，1]毫米时，既能卡扣牢固，还不会增加第二连接器20的体积。
凸起侧面2442与凸起外侧面2444相交形成的夹角B为锐角，即，0°<B<90°。进一步地，在一些例子中，夹角B大于或者等于45度而小于90度(即(45°≤B<90°))，例如夹角B可以为45度、50度、55度、60度、65度、70度、75度、85度、88度、无限接近90度等等。在另一些例子中，凸起侧面2442与凸起外侧面2444垂直，即夹角B也可为90度。在又一些例子中，凸起侧面2442与凸起外侧面2444相交形成的夹角B为钝角，即夹角B大于90度且小于180度。本实施方式中，凸起侧面2442为平面；在其它一些例子中，凸起侧面2442为曲面，曲面的曲率中心位于安装槽13内。当第二连接器20安装在第一连接器10上时，凸起侧面2442与缺口侧面1362结合。
请参阅图3和图4，夹角B与夹角A对应，即：当45°≤A<90°时，则45°≤B<90°；当A＝90°时，则B＝90°；当90°<A<180°时，则90°<B<180°。在一些例子中，夹角A和夹角B相等，例如A＝B＝45度、A＝B＝60度、A＝B＝80度、A＝B＝85度、A＝B＝90度等等。在另一些例子中，夹角A略小于夹角B，例如，B＝45度，则A＝44度；B＝85度，则A＝84度等等。在其它一些例子中，夹角A略大于夹角B，例如，B＝44度，则A＝45度；B＝84度，则A＝85度等等。
在一些实施方式中，当第二连接器20安装在第一连接器上10时，凸起本体244 的一部分收容在安装槽13内，凸起本体244的另一部分从安装槽13(在X所指的方向及X所指的反方向上)伸出至第一连接器10外。
在一些实施方式中，缺口侧面1362为凹凸面，对应地，凸起侧面2442也为凹凸面。凹凸面用于增加缺口侧面1362和凸起侧面2442的摩擦，使得凸起侧面2442与缺口侧面1362咬合更紧密。例如缺口侧面1362上设置有多个间隔的颗粒状的凸起以形成凹凸面，凸起侧面2442设置有多个与凸起相适配的凹槽形成凹凸面，当缺口侧面1362和凸起侧面2442结合时，凸起和凹槽相互配合。或者，缺口侧面1362上设置有多个条纹形成凹凸面，凸起侧面2442上设置有多个与条纹相匹配的沟槽形成凹凸面，当缺口侧面1362和凸起侧面2442结合时，条纹和沟槽相互配合。
在一些实施方式中，当两个安装槽侧面132中的一个设置有缺口136(即，第一结合件12)，而另一个安装槽侧面132不开设缺口时，对应地，连接本体21的一侧设置有与缺口136相配合的弹性凸起24(即，第二结合件22)，而另一侧则不设置弹性凸起24。当第一连接器10和第二连接器20结合时，安装槽侧面132上的缺口136(即第一结合件12)和连接本体21上的弹性凸起24(即第二结合件22)结合，完成第一连接器10和第二连接器20的结合。在另一些实施方式中，当两个缺口136设置在同一个安装槽侧面132上，对应的，连接本体21的一侧设置有与两个缺口136相配合的弹性凸起24(即，第二结合件22)，而另一侧则不设置弹性凸起24。本申请对安装槽侧面132上缺口136的数量及位置不做要求，只需要满足弹性凸起24的凸起本体244的数量及位置与缺口136的数量及位置对应即可。
请参阅图2、图3和图5，两个弹性凸起24的远离连接主体212的侧面(即弹性本体侧面2426)均设置有连接杆23，也即是，连接杆23的数量为2。连接杆23的长度L1略大于收容槽14的长度L2，也即是，当第二连接器20安装在第一连接器10上时，连接杆23至少部分凸出于基座侧面116。连接杆23用于供安装者按压，从而将按压力传导至弹性本体242的自由端2422，使弹性本体242的自由端2422朝向间隙246弯曲，以带动凸起本体244脱离缺口136。连接杆23可以呈杆状、柱状、板状等等，在此不做限制，在本实施方式中，连接杆23大致呈板状，连接杆23的深度T大致等于自由端2422的端面至凸起侧面2442的直线距离D。在其他一些实施方式中，连接杆23的长度L1也可以等于收容槽14在基座11径向上的长度L2，也即是，当第二连接器20安装在第一连接器10上时，连接杆23和基座侧面116齐平，使得整个动力组件100的外轮廓更加完整，此时，若需要将第二连接器20从第一连接器10上拆卸下来时，只需要用将手指伸入收容槽14对连接杆23施加按压力即可。
请参阅图5，在一些实施方式中，连接杆23包括位于安装槽13两侧的第一连接杆 232和第二连接杆234，收容槽14包括位于安装槽13两侧的第一收容槽142和第二收容槽144。当第一连接器10和第二连接器20结合时，第一连接杆232对应收容在第一收容槽142中，第二连接杆234对应收容在第二收容槽144中。在一些例子中，可以通过设置第一连接杆232和第二连接杆234的相对位置来区分不同型号的动力组件100，以防止将不同型号的第一连接器10和第二连接器20混用，造成无人飞行器的损坏。在一些例子中，一种型号的动力组件100中，第一连接杆232和第二连接杆234共轴线(请参阅图1)；而在另一种型号的中，第一连接杆232和第二连接杆234错开设置使二者的轴线错开，如此，不同型号的第一连接器10便不能共用。在另一些例子中，可以通过设置第一连接杆232的数量和第二连接杆234的数量来区分不同型号的动力组件100，例如在一个动力组件100中，第一连接杆232和第二连接杆234的数量均为1，而在另一个动力组件100中，第一连接杆232的数量为1，第二连接杆234的数量为2，或者第一连接杆232和第二连接杆234的数量均为2。在其他一些例子中，可以将第一连接杆232和第二连接杆234设置不同形状或大小、以区分不同型号的动力组件100。
在一些实施方式中，第一连接杆232和第二连接杆234通过设置不同的位置、数量、形状、大小中的至少两种的结合，以区分不同型号的动力组件100。例如两型号的第一连接杆232和第二连接杆234位置和形状各不相同、位置和数量各不相同、位置和大小各不相同等等。
请参阅图1和图2，转轴30穿设并固定在第一连接器10上，桨叶50安装在第二连接器20上。转轴30用于限制第二连接器20相对于第一连接器10在第一方向(可以是X所指的方向、X所指的反方向、Y所指的方向、及Y所指的反方向)上的移动，其中，X所指的方向及X所指的反方向是沿着安装槽13的长度方向，Y所指的方向及Y所指的反方向是沿着收容槽14的长度方向，X垂直于Y。第一结合件12和第二结合件22用于限制第二连接器20相对于第一连接器10在第二方向(可以是Z所指的方向)上移动，其中第一方向和第二方向垂直。
具体地，请结合图3，第一连接器10的中心开设有贯穿基座底面114和安装槽底面134的连接孔17，第二连接器20上开设有与连接孔17对应的通孔26。转轴30包括第一端32和与第一端32相背的第二端34。转轴30穿过连接孔17并固定安装在第一连接器10上，转轴30的第一端32至少部分凸出于基座底面114，转轴30的第一端32用于与动力机构(如电机)连接，转轴30的第二端34凸出于安装槽底面134，并收容在安装槽13内。弹性件40套设在转轴30的第二端34并抵持安装槽底面134。弹性件40可以是弹簧，也可以是橡胶、硅胶等材料制成的弹性垫圈，在本实施方式中， 弹性件40为弹簧。当第一连接器10和第二连接器20结合时，转轴30的第二端34伸入到通孔26并从第一连接器10的远离安装槽底面134的表面伸出。弹性件40位于安装槽底面134与连接本体21之间。在第二连接器20安装在第一连接器10上时，弹性件40被第二连接器20压缩，相反地，弹性件40给第二连接器20提供一个相反的压迫力，凸起本体244在弹性件40的压迫力的作用下，紧紧卡在缺口136中，即，在弹性件40的压迫力的作用下，第二结合件22与第一结合件12紧密配合，此时，转轴30限制第二连接器20相对于第一连接器10在第一方向上移动，第一结合件12和第二结合件22限制第二连接器20相对于第一连接器10在第二方向上移动。
在一些例子中，转轴30的第一端32收容在连接孔17中，也即，转轴30的第一端32不超出基座底面114，第一连接器10通过连接孔17直接或间接安装在动力结构的输出轴上。
两个桨叶50相对且分别安装在第二连接器20的两个主体曲面2124上，两个桨叶50朝着背离连接主体212的方向延伸。在某些实施方式中，两个桨叶50可以可拆卸的安装在第二连接器10上，例如通过卡接、螺钉连接等方式实现可拆卸连接，两个桨叶50也可以固定安装在第二连接器10，例如通过焊接、一体成型等方式实现二者的固定连接。
当需要将第一连接器10和第二连接器20结合时，先将第二连接器20的连接本体212对准安装槽13，两个连接杆23对准收容槽14，通孔26对准转轴30的第二端34，再朝着Z所指的反方向将第二连接器20朝第一连接器10移动，与此同时，朝内按压连接杆23，使得弹性本体242由原始状态朝向间隙246发生弹性变形(弯曲)，且继续将第二连接器20朝着Z所指的反方向移动，使得凸起本体244收容在两安装槽侧面132之间，弹性件40的两端分别抵持在第二连接器20的底面和安装槽底面134，当第二连接器20移动至第一连接器10的预定位置(凸起本体244和缺口136对准的位置)时，松开连接杆23，弹性本体242在自身弹力作用下回复原始状态，使得凸起本体244伸入缺口136，并在弹性件40的压迫力的作用下，凸起本体244紧紧扣合在缺口136内，缺口侧面1362和凸起侧面2442结合，由此完成第一结合件12和第二结合件22的结合。至此，转轴30可限制第二连接器20相对于第一连接器10在第一方向(可以是X所指的方向、X所指的反方向、Y所指的方向、及Y所指的反方向)上的移动，第一结合件12和第二结合件22用于限制第二连接器20相对于第一连接器10在第二方向(可以是Z所指的方向)上移动。
当需要将第一连接器10和第二连接器20分离时，只需要按压连接杆23，使得凸起本体244脱离缺口136，紧接着，朝着Z所指的方向将第二连接器20从第一连接器 10中抽出，即可将第一连接器10和第二连接器20分离。
请参阅图6和图7，在另一些实施方式中，第一连接器10的结构与第二连接器20的结构与上述实施方式基本相同，不同之处在于：转轴30穿设并固定在第二连接器20上，两个桨叶50安装在第一连接器10上。
具体地，第二连接器20的中心开设有贯穿第二连接器20的顶面和底面的通孔26，第一连接器10的中心开设有贯穿基座底面114和安装槽底面134的连接孔17，连接孔17与通孔26对应的。转轴30包括第一端32和与第一端32相背的第二端34。转轴30穿过通孔26并固定安装在第二连接器20上，转轴30的第二端34至少部分凸出于连接本体212的顶面，转轴30的第一端32用于与动力机构(如电机)连接，转轴30的第一端32部分凸出于连接本体212的底面。弹性件40套设在转轴30的第一端32并抵持连接本体212的底面。
两个桨叶50安装在第一连接器10的相对两侧，一个与安装槽13的一侧开口对应，另一个与安装槽13的另一侧开口对应。两个桨叶50安装在第一连接器10的方式与前述实施方式中两个桨叶50安装在第二连接器20的方式相同，在此不再赘述。
在转轴30穿设并固定在第二连接器20上时，若第一连接器10和第二连接器20结合时，先将第二连接器20的连接本体212对准安装槽13，连接杆23对准收容槽14，转轴30的第一端32对准连接孔17，再朝着Z所指的反方向将第二连接器20朝第一连接器10上移动，转轴30的第一端32逐渐伸入到连接孔17中并从基座底面114伸出，与此同时，朝内按压连接杆23，使得弹性本体242由原始状态朝向间隙246发生弹性变形(弯曲)，且继续将第二连接器20朝着Z所指的反方向移动，使得凸起本体244收容在两安装槽侧面132之间，且弹性件40位于安装槽底面134与连接本体21之间。当第二连接器20移动至第一连接器10的预定位置(凸起本体244和缺口136对准的位置)时，松开连接杆23，弹性本体242在自身弹力作用下回复原始状态，使得凸起本体244伸入缺口136，并在弹性件40的作用下紧紧卡扣在缺口136中，即，在弹性件40的作用下，第二结合件22紧扣在第一结合件12上。同样地，转轴30可限制第二连接器20相对于第一连接器10在第一方向(可以是X所指的方向、X所指的反方向、Y所指的方向、及Y所指的反方向)上的移动，第一结合件12和第二结合件22用于限制第二连接器20相对于第一连接器10在第二方向(可以是Z所指的方向)上移动。
在某些实施方式中，在转轴30穿设并固定在第二连接器20上时，两个桨叶50还可相对且分别安装在第二连接器20的两个主体曲面2124上，两个桨叶50朝着背离连接主体212的方向延伸。此时，两个桨叶50具体的安装方式同前所述，在此不再赘述。
请参阅8和图9，在另一实施方式中，第一连接器10包括基座11和第一结合件12，第一结合件12为弹性卡勾16(对应上述实施方式的弹性凸起24)，第二连接器20包括连接本体21及设置在连接本体21上的第二结合件22，第二结合件22为卡槽216(对应上述实施方式的缺口136)。
具体地，基座11包括基座顶面112、基座底面114和基座侧面116，其中，基座顶面112和基座底面114位于基座11的相背两侧，基座侧面116环绕基座顶面112和基座底面114并连接基座顶面112及基座底面114。
基座11上开设有贯穿基座顶面112和基座侧面116相对两侧的安装槽13。安装槽13包括安装槽底面134和两个安装槽侧面132，两个安装槽侧面132相对且平行，两个安装槽侧面132垂直于安装槽底面134。安装槽底面134延伸形成两个相对的基座凸出部118。
请继续参阅图8和图9，弹性卡勾16包括相连接的弹性主体160、卡勾主体164、及连接杆168。
弹性主体160包括结合端1602、与结合端1602相背的悬空端1604、及弹性主体侧面1606。结合端1602固定在安装槽13内的基座凸出部118上，悬空端1604与安装槽侧面132之间形成有空隙166，空隙166自悬空端1604延伸至结合端1602，悬空端1604在受到朝空隙166一侧的力时能够朝空隙166一侧弯曲。弹性主体侧面1606位于弹性主体160的远离安装槽侧面132的一侧。两个基座凸出部118上均设置有弹性主体160。
卡勾主体164自弹性主体侧面1606朝远离安装槽侧面132的一侧延伸形成。卡勾主体164包括卡勾侧面1642、卡勾外侧面1644、及卡勾连接面1646。卡勾侧面1642位于靠近结合端1602的一侧。卡勾外侧面1644自卡勾侧面1642朝悬空端1604的方向延伸，卡勾外侧面1644与弹性主体侧面1606平行。卡勾连接面1646为过渡连接卡勾外侧面1644和弹性主体侧面1606的连接面。在一个实施方式中，卡勾连接面1646可为曲面。在另一实施方式中，也可以采用平面过渡连接卡勾外侧面1644和弹性主体侧面1606，也即，卡勾连接面1646可为平面。在另一个实施方式中，卡勾外侧面1644可省略，此时，卡勾连接面1646直接连接卡勾侧面1642和弹性主体侧面1606，且卡勾主体164自悬空端1604至结合端1602的方向上的高度H2逐渐增大。卡勾侧面1642与卡勾外侧面1644相交形成的夹角C，夹角C的角度范围的选取与前述实施方式中的夹角A的角度范围的选取相同，在此不再赘述。卡勾主体164的最大高度H2小于空隙166的宽度W2，以为卡勾主体164的变形预留足够的空间。
基座11上还开设有容纳槽(未示出，可参考收容槽14)，容纳槽贯穿基座侧面 116和基座顶面112，并与空隙166连通，容纳槽垂直于安装槽13。连接杆168的一端连接安装在弹性主体160的朝向安装槽侧面132的一侧上，连接杆168的另一端穿设容纳槽后部分凸出于基座侧面116。
连接本体21包括主体侧面2122和主体曲面2124，主体侧面2122和主体曲面2124各有两个且两两相对。两个主体侧面2122平行相对且分别连接一个主体曲面2124。两个主体侧面2122均朝连接本体21内部凹陷形成卡槽216(可参考缺口136)，两个卡槽216在X所指方向贯穿两个主体曲面2124。卡槽216包括靠近安装槽底面134的卡槽侧面2162，卡槽侧面2162与主体侧面2122相交形成的夹角D，夹角D的角度范围的选取与前述实施方式中的夹角B的角度范围的选取相同，在此不再赘述。夹角D和夹角C对应，对应关系如前述夹角B和夹角A的对应关系，也不再赘述。当第二连接器20安装在第一连接器10上时，卡槽侧面2162与卡勾侧面1642结合。
