请一并参阅图1和图2，图1是本发明提供的无人机第一实施例的结构示意图，图2是图1实施例中A区域的放大结构示意图。
如图1所示，该无人机100包括无人机主体110、安装平台120、柱体130以及锁固件140。所述柱体130以及锁固件140构成连接组件。
可以理解，所述柱体130以及锁固件140构成的连接组件可以用来连 接多种被连接的第一被连接件和第二被连接件，其中柱体130固定于第一被连接件并穿过第二被连接件，通过锁固件140锁固。本实施例中，以无人机100中应用的场景进行说明。
其中，柱体130固定于无人机主体110，且自无人机主体110表面凸出；安装平台120用于固定外接设备，且设有与柱体130适配的第一贯穿孔121(见图2)；柱体130自安装平台120一侧穿过第一贯穿孔121并伸出至安装平台120相背的另一侧，锁固件140固定于柱体130伸出第一贯穿孔121的部分，进而将安装平台120锁固于无人机主体110。

其中，第一环形槽351的槽宽等于或大于第一贯穿孔321的孔深，第二环形槽331的槽宽等于或大于弹性圈350的长度。
锁固件340自柱体330轴线向径向延伸的至少一部分的长度大于第二贯穿孔322对应锁固件340径向延伸方向的半径，以便锁固件340能够将安装平台320锁固于无人机主体310。
请一并参阅图5，柱体330的自由端呈圆锥形、圆盘形或蘑菇形，使得柱体330能够快速方便穿过第一贯穿孔321后，继续穿过第二贯穿孔322并伸出至安装平台320相背的另一侧，伸出第一贯穿孔321的部分设有径向的第三贯穿孔332。其中，锁固件340是插销，插销340穿过第三贯穿孔332进而将安装平台310锁固于无人机主体310。
请一并参阅图6，插销340包括弯折连接的直条件341和弯曲件342，直条件341穿过第三贯穿孔332，弯曲件342位于第三贯穿孔332外，且弹性夹持柱体330的外壁，不易受振动影响而脱离柱体330。
具体的，锁固件340将安装平台310锁固于无人机主体310后，弹性圈350暴露于安装平台320外的部分受安装平台320与柱体330的第二环形槽331的槽壁或无人机主体310之间的挤压而形变，并使得弹性体350不能轴向移动而脱离第一贯穿孔321。
请参阅图7，图7是本发明提供的无人机第四实施例的局部放大结构 示意图，图8是图7实施例中柱体的结构示意图。
无人机主体410设有盲孔411，盲孔411内固定有与盲孔同轴的螺纹柱(图未示)，柱体430固定于无人机主体410的一端端面内陷形成内螺纹孔，柱体430具有内螺纹孔的一端插入无人机主体410的盲孔411，且内螺纹孔与螺纹柱螺接。其中，无人机主体410设有一个或多个柱体430，比如无人机主体410设有四个、六个或八个柱体430，且多个主体430在同一水平面上。本实施例中，锁固件440的数量小于或等于柱体430的数量。
在其他实施例中，盲孔411底面还可以设有挡块412，柱体430具有内螺纹孔的一端设有止转凸台433，柱体430旋入盲孔411后，止转凸台433与挡块412相互卡顶进而防止柱体430继续旋转。
为了方便理解，现将安装平台安装在无人机主体的实施步骤列举如下：
首先，将弹性件安装至安装平台的第一贯穿孔，利用弹性件的形变能力将其安装在安装平台的第一贯穿孔，限制弹性件的轴向移动，利用弹性件的第一环形槽限制其径向向移动。
然后，将柱体安装到无人机飞行器上，并保证多个柱体的最高点在同一平面上。
下一步，将装好弹性件的安装平台直接压进柱体，压入时弹性件因受挤压侧壁变薄，安装平台随弹性件滑入柱体的第二环形槽。
最后，将锁固件插进柱体的第三贯穿孔的孔位。
其中，无人机主体卸载安装平台的流程步骤正好与安装步骤相反，将锁固件插从柱体的第三贯穿孔的孔位取出，再取出安装平台即可，从而使得无人机主体能够快速安装和卸载安装平台。
综上所述，本领域技术人员容易理解，本发明提供的无人机由于设有柱体和锁固件，通过柱体和锁固件可以在无人机主体上快速搭载和拆卸安装平台，该无人机结构简单，安装方便且费时少。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
