Specific embodiment
Below in conjunction with the accompanying drawings, it is further elaborated with one of which embodiment of the present invention.
As shown in figure 1, multi-rotor unmanned aerial vehicle of the invention includes that central plate D, multiple are evenly distributed on around central plate D
Horn B, horn B is connected by folded piece C with central plate D, and motor and propeller A are fixed with the end of each horn；
Undercarriage E is provided with below central plate.
Referring to Fig. 2-7, multi-rotor unmanned aerial vehicle horn folded piece C of the invention is connected by horn connector 1 with horn,
