[0031] As shown in Figures 1-4As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the top of the arm 2 is provided with a movable groove 201, and a drive motor 10 is provided inside the movable groove 201. The output shaft of the drive motor 10 is fixedly connected to the bottom of the propeller base 3. The cooperation between the drive motor 10 and the propeller base 3 enables the drive motor 10 to start and drive the propeller base 3 to rotate, thereby driving the propeller 4 to rotate, so that the fuselage 1 can take off. The bottom sides of the propeller base 3 are provided with connecting grooves 301. The inner wall of the connecting groove 301 is fixedly connected with a spring piece 12. One end of the spring piece 12 is fixedly connected with a C-shaped rod 11. The outside of the C-shaped rod 11 overlaps with the inside of the connecting groove 301.

[0033] like Figures 1-4 As shown, firstly, the curved design of the fuselage 1 makes the head of the fuselage 1 flat and round, and smooth and streamlined, thereby reducing the frontal area during flight, reducing the flight drag of the drone, and increasing the stability during flight. When the drone lands, the foot pads 6 and anti-slip pads 61 increase the contact area between the bottom and the ground, thereby preventing the drone from tilting and falling. Secondly, the drive motor 10 drives the propeller 4 to rotate, and the C-shaped rod 11 and the locking block 111 rotate along the groove 202 and the slot 2021, thereby driving the fuselage 1 to take off. When replacing the propeller mount 3, press the C-shaped rod 11 inward by hand, so that the C-shaped rod 11 moves inward along the connecting groove 301 to squeeze the spring piece 12, causing the locking block 111 to be forced inward to squeeze the rubber strip 112.
