[0025] Further, the fuselage 1 comprises an upper plate 11 and a bottom plate 12 arranged at intervals, screw holes are arranged on the bottom plate 12 to realize the connection between the bottom plate 12 and the blade protection fence 31 after the screw is installed into the screw hole, preferably, the bottom plate 12 and the blade protection fence 31 are connected through six groups of screw holes, wherein two groups of screw holes are located at the head of the bottom central frame, two groups of screw holes are located at the tail of the bottom central frame, and four groups of screw holes are located on the central frame of the bottom plate 12. Such screw holes are convenient for carrying different sizes of flight control boards on the unmanned aerial vehicle during flight training of the unmanned aerial vehicle. Further, six groups of screw holes are arranged on the upper plate 11, the six groups of screw holes on the upper plate 11 are symmetrically arranged with the six groups of screw holes on the bottom plate 12, so that the balance of the entire fuselage 1 is ensured while the aesthetics of the entire fuselage 1 is increased. Further, the unmanned aerial vehicle can be easily and detachably maintained by a maintenance personnel through the screw holes. A plurality of hollow structures 14 are arranged on the upper plate 11, and a plurality of heat dissipation holes 15 are arranged on the bottom plate 12, so that the fuselage 1 is heat-dissipated, and the arrangement of the hollow structures 14 and the heat dissipation holes 15 can reduce the overall weight of the fuselage 1.

[0026] Further, the central frame 13 comprises a top central frame located on the upper plate 11 and a bottom central frame located on the bottom plate 12, a battery module is further installed on the top central frame, and a PCB board 9 is further installed on the bottom central frame.

[0027] Further, the paddle assembly 2 comprises a paddle 21, a motor 22, a paddle clamp 23 and a mounting base 24, the paddle 21 is connected with the paddle clamp 23, the paddle clamp 23 is sleeved on the motor 22 shaft of the motor 22, and the motor 22 is installed on the protection assembly 3 through the mounting base 24. When the unmanned aerial vehicle runs, the motor 22 rotates to drive the paddle 21 to rotate, thereby providing flight power for the unmanned aerial vehicle.

[0028] Further, the target side of the paddle protection fence 31 is attached with an anti-collision layer 33, and the target side is the peripheral surface of the paddle protection fence 31 away from the fuselage 1. Preferably, the paddle protection fence 31 can be made of plastic material, which can reduce the overall weight of the unmanned aerial vehicle. The anti-collision layer 33 can be made of sponge material or rubber material. It can be understood that the paddle 21 is protected in the protection fence, and when the unmanned aerial vehicle collides, the paddle protection fence 31 can protect the paddle 21, reduce the direct collision between the paddle 21 and the impact object, and thereby reduce the damage degree of the paddle 21.

[0034] Further, the tail fin 7 further comprises an antenna through hole 72 for passing through the antenna of the receiver. Such a design makes the antenna of the receiver independent of other signal lines inside the fuselage 1, reducing signal interference.
