Then the hydraulic cylinder 303 is started to drive the support frame 304, and the support frame 304 drives the connecting frame 305, so that the connecting frame 305 drives the first circular arc plate 312, the clamping plate 332 and other parts to return to the lower side of the unmanned aerial vehicle body 100, thereby the spraying repair mechanism 300 is retracted, and finally the operator controls the unmanned aerial vehicle to return.

[0060] In addition, when the spraying repair mechanism 300 needs to be fixed on the unmanned aerial vehicle body 100 by means of the mounting mechanism 400, first, the storage tank 301 is moved to be attached to the lower surface of the unmanned aerial vehicle body 100, then the rotating plates 402 are adjusted to rotate along the inner walls of the fixing seats 327 on both sides of the storage tank 301, the two rotating plates 402 are turned into the welding seats 404, so that the rotating plates 402 are attached to the inner walls of the welding seats 404, and at the same time, the threaded rods 405 on the welding seats 404 are aligned with the threaded holes 403 on the rotating plates 402. Then the threaded rods 405 are rotated by means of the anti-slip patterns 406 to be connected with the connecting holes 313, so that the installation of the spraying repair mechanism 300 is completed. When the spraying repair mechanism 300 needs to be disassembled from the unmanned aerial vehicle body 100 for maintenance or cleaning, first, the threaded rods 405 are separated from the threaded holes 403 by rotating the threaded rods 405 by means of the anti-slip patterns 406, and then the rotating plates 402 are separated from the inner walls of the welding seats 404, so that the spraying repair mechanism 300 can be disassembled.
