[0020] In the specific implementation process, Figure 1-Figure 7 As shown, it includes a flamethrower mechanism 1 and a body 2 of the UAV.

[0026] Working principle of the present invention: when the device is used, when it is necessary to assemble the flame-spraying mechanism 1 with the machine body 2, the staff only needs to first raise the two supporting legs 8 at the bottom of the machine body 2, and then move the entire flame-spraying mechanism 1 to the bottom of the machine body 2 through a number of universal wheels 22. At this time, the rotating crank 36 drives the two worms 35 to rotate at the same time. Under the action of the two worms 35 and the two transmission worm wheels 32, the two threaded sleeves 27 rotate in the same direction at the same time, and finally the first mounting platform 3 at the top of the flame-spraying mechanism 1 moves upward relative to the second mounting platform 20. After the columnar block 5 is fully inserted into the inside of the connecting ring seat 4, the hexagonal block 15 is rotated with a wrench to drive the bidirectional screw rod 13 to rotate. Under the action of the bidirectional screw rod 13, the two sliders 14 approach each other along the slide groove 12 until the two limit columns 7 enter the inside of the limit groove 6. The assembly work between the flame-spraying mechanism 1 and the machine body 2 can be completed. The disassembly is similar, and the operation is simple and convenient.
