The front upper semi-disc 2012 is fastened to the front lower semi-disc 2011 by a buckle, and the rear lower semi-disc 2021 is fastened to the rear upper semi-disc 2022 by a buckle. The front end of the inverted support rod 301 is then engaged in the inverted support rod slot 302. The crane or gantry crane... Place the drone and tooling vehicle in a horizontal position. The operator disassembles the lower ends of the fixed-wing left support beam 303 and the fixed-wing right support beam 304 from the front disc support frame, rotates the fixed-wing left support beam 303 and the fixed-wing right support beam 304, and fixes the lower ends of the fixed-wing left support beam 303 and the fixed-wing right support beam 304 to the rear end of the base. Rotate the front disc and the rear disc so that the tail of the drone faces downwards, restoring it to its initial placement state.
