[0029] Furthermore, the first flight rod 25 and the second flight rod 27 are both equipped with electric motors (not shown in the figure) for driving the first blade 26 and the second blade 28. The electric motors drive the first blade 26 and the second blade 28 to rotate at a high altitude, thereby allowing the drone to fly in the air.

[0030] Furthermore, a self-locking member for fixing the first flight rod 25 and the second flight rod 27 is provided on the fuselage 1. The self-locking member can reduce the shaking and deviation of the drone during flight.

[0033] Embodiment 2 is described based on Embodiment 1 with reference to the accompanying drawings:

[0034] The self-locking member includes a connecting block 22 which is arranged above the first flight rod 25 and the second flight rod 27 and connected to the fuselage 1, a threaded rod 213 which penetrates the connecting block 22 is vertically threadedly connected, a limiting plate 211 for limiting is fixed on the circumferential surface of the threaded rod 213, and the limiting plate 211 is located below the connecting block 22, and the limiting plate 211 prevents the threaded rod 213 from being separated from the connecting block 22, and threaded holes for threaded connection of the threaded rod 213 are provided on the top surfaces of the first flight rod 25 and the second flight rod 27, so that the threaded rod 213 can be threadedly connected to the inside of the threaded holes, thereby fixing the first flight rod 25 and the second flight rod 27 so that they will not shake during flight;

[0035] Embodiment 3 is described based on Embodiment 2 with reference to the accompanying drawings:

[0036] A storage tank is provided on the upper surface of the connection block 22 , a pressure sensor 31 is provided in the storage tank, a warning light 32 electrically connected to the pressure sensor 31 is provided on the upper surface of the connection block 22 , and the pressure sensor 31 can control the opening and closing of the warning light 32 .

[0037] Working principle: When the present application is in use, the battery is charged through the charging port, and at the same time, the four threaded rods 213 are rotated so that the threaded rods 213 are respectively threadedly connected to the threaded holes opened in the first flight rod 25 and the second flight rod 27. When the bottom surface of the head of the threaded rod 213 is pressed against the upper surface of the connecting block 22, the flight rod is fixed; in this state, the bottom surface of the head of the threaded rod 213 presses down the pressure sensor 31, and the pressure sensor 31 sends a signal to control the indicator light 32 to turn on, and the staff further receives a prompt that the flight rod has completed self-locking fixation;

[0038] When flight is required, the controller controls the motor to drive the first blade 26 and the second blade 28 to rotate at high speed, so that the drone can fly. After the flight is completed, the threaded rod 213 is rotated upward to disengage from the threaded hole. With the use of the damping shaft, the first flight rod 25 and the second flight rod 27 are folded inward, thereby realizing the folding of the drone.
