Both sides of the middle of the upper end of the liquid storage box 2 are fixedly installed with connecting rods 21. The upper end of the connecting rods 21 is fixedly installed with dome plates 22. The dome plates 22 are inserted into the middle of the through hole 12. The connecting rods 21 are connected with the slots 18.

[0023] The specific settings and effects of the embodiment will be described below. When disassembling, the user only needs to press the two U-shaped push plates 19 inward to extrude, drive the two clamping plates 17 to extrude the internal springs 16 along the movable grooves 13. With the movement of the clamping plate 17, the clamping groove 18 opened by the clamping plate 17 will gradually cancel the limiting of the connecting rod 21, and at the same time the clamping plate 17 will move away from the round through hole 12 to cancel the abutment of the lower end of the upper dome plate 22. At this time, the operator can directly disassemble the liquid storage box 2. When installing, the upper dome plate 22 of the liquid storage box 2 is inserted into the round through hole 12 opened in the base 11. The dome plate 22 cannot touch the bottom under the shielding of the clamping plate 17. At this time, press the U-shaped push plate 19 to extrude the spring 16 to move the clamping plate 17 inward. Without the shielding of the clamping plate 17, the dome plate 22 can touch the bottom. Then release the limiting of the U-shaped push plate 19. Under the action of the spring 16, the clamping plate 17 will reset. During the process, the connecting rod 21 will be clamped in the middle of the clamping groove 18, and at the same time the clamping plate 17 will be clamped directly below the dome plate 22 to realize the fixation of the liquid storage box 2. Through the setting of the quick release structure, the liquid storage box 2 can be quickly disassembled, and after multiple disassemblies, the liquid storage box 2 will not be fixed unstable, which has higher practicality.

[0024] In example two, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the liquid storage box 2 is inserted into the middle of the round through hole 12 through the connecting rod 21 and the dome plate 22 to realize clamping with the unmanned aerial vehicle body 1.

The dome plate 22 cannot touch the bottom under the shelter of the clamping plate 17. At this time, press the U-shaped push plate 19 to extrude the spring 16 and make the clamping plate 17 move inward. Without the shelter of the clamping plate 17, the dome plate 22 can touch the bottom. Then release the limit of the U-shaped push plate 19. Under the action of the spring 16, the clamping plate 17 will reset. In the process, the connecting rod 21 will be clamped in the middle of the clamping groove 18, and at the same time the clamping plate 17 will be clamped directly below the dome plate 22 to realize the fixation of the liquid storage box 2. Then control the unmanned aerial vehicle body 1 to take off. In the process, the nozzle 24 will spray the liquid in the liquid storage box 2 out to work. After the spraying work is completed, the liquid is supplemented or the liquid storage box 2 is disassembled for cleaning according to the need. When disassembling, the user only needs to press the two U-shaped push plates 19 inward to extrude the spring 16 inside the two clamping plates 17 along the movable slot 13. With the movement of the clamping plate 17, the clamping groove 18 opened in the clamping plate 17 will gradually cancel the limit of the connecting rod 21, and at the same time the clamping plate 17 will move away from the circular through hole 12 to cancel the abutment of the lower end of the upper dome plate 22. At this time, the operator can directly disassemble the liquid storage box 2. By setting the quick release structure, the liquid storage box 2 can be quickly disassembled. After disassembling several times, the liquid storage box 2 will not be unstable. It has higher practicality.
