[0039] What needs to be further explained is: pulling the pull ring 306 to one side causes the pull ring 306 to drive the rack 307 and the limiting plate 308 to slide, and the spring 309 is compressed, and the rack 307 is disengaged from the inside of the tooth groove 305. At this time, the connecting sleeve 401 and the connecting strip 304 can be rotated to change the angle of the liquid outlet head 403. After adjusting to the appropriate angle, release the pull ring 306. At this time, the tension of the spring 309 causes the rack 307 to be stuck in the inside of the tooth groove 305 again, limiting and fixing the connecting strip 304.

[0040] Working principle: When a drone is used with a retractable nozzle, a liquid storage tank 101 is first provided at the bottom of the drone body 1. The liquid storage tank 101 is provided to facilitate storage of liquid medicine. A liquid injection port 102 is provided on the top of the drone body 1 to facilitate injection of liquid medicine into the liquid storage tank 101. A plurality of wings 2 are provided on the side of the drone body 1. The battery and control module inside the drone body 1 facilitate control of the wings 2 to drive the drone to take off and land. A plurality of liquid outlet pipes 204 are provided at the bottom of the liquid storage tank 101, and the control module can also control the water pump provided inside the liquid storage tank 101 to make the liquid medicine inside the liquid storage tank 101 enter the liquid outlet pipe 204, and is connected to the lifting mechanism 4 through the plurality of liquid outlet pipes 204 to facilitate spraying of the liquid medicine.

[0041] When it is necessary to drive the nozzle to extend or retract, first rotate the limit nut 408 to make the limit nut 408 and the rubber pad 409 move away from one side of the connecting plate 404. At this time, the liquid outlet head 403 can be pulled, and the connecting inner cylinder 402 set on the top of the liquid outlet head 403 rises and falls inside the connecting sleeve 401. At the same time, the connecting plate 2 406 and the limit rod 407 on its top also rise and fall inside the connecting plate 404. After adjusting to a suitable height, rotate the limit nut 408 again so that it and the rubber pad 409 are in contact with the connecting plate 404 at the same time, and the rubber pad 409 is fixed in the limiting groove 405. The friction force generated makes the liquid outlet head 403 fixed to the bottom of the connecting sleeve 401, so as to achieve the effect of controlling the extension and retraction of the liquid outlet head 403. This device is convenient for driving the nozzle to extend or retract.

[0042] When the angle of the nozzle needs to be adjusted, first pull the pull ring 306 to one side so that the pull ring 306 drives the rack 307 and the limiting plate 308 to slide, and the spring 309 is compressed, and the rack 307 is disengaged from the inside of the tooth groove 305. At this time, the connecting sleeve 401 and the connecting strip 304 can be rotated to change the angle of the liquid outlet head 403. After adjusting to the appropriate angle, release the pull ring 306. At this time, the tension of the spring 309 causes the rack 307 to be stuck in the inside of the tooth groove 305 again, limiting and fixing the connecting strip 304. This device facilitates the adjustment of the angle of the nozzle.

[0043] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
