The novel unmanned aerial vehicle of claim 6, wherein the support frame (2) comprises a support frame main body (204) fixedly connected with the fuselage, the support frame main body (204) is provided with at least three protruding arms (206), each protruding arm (206) is rotatably connected with a rotating arm (208), the foot stand pipe (202) is fixed on the rotating arm (208), and the rotating arm (208) can be driven by a driving device to rotate.
8. A new type of unmanned aerial vehicle according to claim 7, characterized in that the fixed support (12) is rotatably connected to one of the third supports (8) at one end and is driven to rotate by a motor, and is rotatably connected to the other third support (8) at the other end and is provided with the fourth brake device.
9. A novel drone according to claim 8, characterised in that the lifting mechanism is a pneumatic cylinder driving one of the crossbars (314) to lift.
10. A new type of unmanned aerial vehicle according to claim 9, characterized in that the first support (4) and the third support (8) are driven by pneumatic means to perform lifting or telescoping movements; the first rotating mechanism and the second rotating mechanism are both motors; the telescopic rod (1406) is driven by a pneumatic device to stretch, and the arc-shaped brake block (1602) is driven by the pneumatic device to move relatively or reversely.
