[0022] When in use, first open the material picking box door on the front side of the delivery box 2, place the delivery items inside the delivery box 2, then start the second servo motor 71 to drive the second gear 73 to rotate through the output shaft, so that the two second rack plates 72 drive the two clamping plates 74 to move relative to each other to fix the delivery items, then close the material picking box door, and then start the drone body 1 to drive the delivery box 2 and the delivery items to the pickup position through the cooperation of the camera, and finally the staff will take the delivery items out of the delivery box 2.

[0023] It is worth noting that the first servo motor 62 and the second servo motor 71 appearing in the present application document are both conventionally known devices, and the first servo motor 62 and the second servo motor 71 are both externally connected to a driving power supply and a control switch, and the driving power supply is arranged inside the drone. The standard parts used in the present application document can all be purchased from the market, and the specific connection methods of each part are connected by conventional means such as mature bolts, rivets, welding, etc. in the prior art, and the machinery, parts and equipment are all conventional models in the prior art, and the circuit connection adopts the conventional connection method in the prior art. The contents not described in detail in the description belong to the prior art known to professional and technical personnel in this field, and will not be described in detail here.

[0024] In summary, the drone with a delivery structure is provided with a cleaning brush component 5 and a driving component 6, and the first servo motor 62 is started to drive the threaded rod 63 to rotate through the output shaft, so that the threaded block 64 drives the first rack plate 65 to move left or right. At this time, the first rack plate 65 and the fan gear 53 are used in coordination, so that the cleaning brush 52 is deflected around the rotating shaft 51 to clean the dust at the camera lens, thereby avoiding affecting the viewing line of sight and improving the practicality of the device. By providing a fixing component 7, the delivery items are placed inside the delivery frame 2. At this time, the second servo motor 71 is started to drive the second gear 73 to rotate through the output shaft. The coordinated use of the second gear 73 and the two second rack plates 72 enables the two clamping plates 74 to move relative to each other to fix the delivery items, thereby preventing the items from moving and affecting the flight of the drone, further improving the practicability of the device and solving the problem that drones are currently also used in the delivery field. Since drones work in the outside world for a long time, dust from the outside world will adhere to the camera, and the existing drones do not have a cleaning function, which will affect the viewing line of sight. At the same time, when the existing drones use the delivery box for delivery, since the delivery box does not have a structure to fix the delivery items, the items will move at this time, and their center positions will be different, which is easy to affect the flight of the drone.
