Technical Problem
传统的螺纹套组件方式连接结构，能让机臂和中心盘连接稳固，但很难防松，同时折叠时，只能往一个方向，不易避位，当需要避位时，需对前后机臂安装结构进行错位，增大尺寸空间、结构重量和复杂度
Benefits of technology
本发明的螺纹套件与中心盘内件相紧配，螺纹套件压紧机臂内件，从而使机臂折叠组件与中心盘悬臂组件实现稳固连接，同时，螺纹套止松组件能对螺纹套组件进行止松，从而增加无人机飞行的安全性和可靠性；本发明机臂折叠组件可通过与折叠转接件连接的第一转轴销钉和第二转轴销钉的两次绕轴旋转，角度分别为和
，使机臂折叠组件在折叠时，即不与无人机其它组件干涉，又能折叠到设计的最小收纳尺寸空间而不增加结构重量和复杂度。

Abstract
The application discloses a kind of machine arm joint loosening and folding structure, including center disc cantilever assembly, machine arm folding assembly and threaded sleeve assembly.The application is tightly matched with center disc inner part by threaded sleeve kit, and threaded sleeve kit is pressed tightly machine arm inner part, so that machine arm folding assembly and center disc cantilever assembly are realized stable connection, simultaneously, the threaded sleeve loosening assembly designed can be loosened to threaded sleeve assembly, so as to increase the safety and reliability of unmanned aerial vehicle flight.The first pivot pin and the second pivot pin of the first pivot pin and the second pivot pin connected by machine arm folding assembly and folding adapter are rotated twice around the shaft, so that machine arm folding assembly can be folded to the smallest storage size space without increasing structural weight and complexity when folding without interfering with other components of unmanned aerial vehicle.
