[0025] The fixing component includes a through groove 21, the through groove 21 is opened at the top of the mounting plate 14, a connecting block 22 is slidably connected inside the through groove 21, the bottom of the connecting block 22 extends to the bottom of the mounting plate 14 and is fixedly connected with a connecting plate 23, a clamping block 24 is fixedly connected to one side of the connecting plate 23, clamping grooves 25 are opened on both sides of the medicine box 16, and the outer side of the clamping block 24 is slidably connected with the inside of the clamping groove 25;

[0026] The fixing component further includes mounting blocks 18, the mounting blocks 18 are equidistantly and fixedly connected to the top of the mounting plate 14, a lead screw 19 is rotatably connected between one sides of the mounting blocks 18, the outer side of the lead screw 19 is threadedly connected with the inside of the connecting block 22, the outer side of the lead screw 19 is rotatably connected with the inside of the connecting rod 13, a motor 20 is arranged on one side of one of the mounting blocks 18, and one end of the output shaft of the motor 20 is fixedly connected with one end of the lead screw 19.

[0027] In the above technical solution, considering that the medicine box 16 has to be fixed only by the support seat of the medicine box 16 to avoid interference during the operation of the UAV. However, there is no way to quickly replace the medicine box 16 and the liquid medicine after the spraying operation, resulting in low efficiency of adding the liquid medicine, affecting the spraying efficiency of the liquid medicine, and causing waste of time and human resources. To solve such problems, the specific operations are as follows: By setting a fixing component at the bottom of the UAV body 1, placing the medicine box 16 at the bottom of the mounting plate 14, and then starting the motor 20 to drive the lead screw 19 to rotate, thereby driving the connecting blocks 22 to approach each other, so that the connecting plate 23 clamps the medicine box 16 from both sides, and at the same time, the clamping block 24 enters the card slot 25 to further fix the medicine box 16. The fixing component can quickly install and disassemble the medicine box 16, and the operator can replace the medicine box 16 in a short time, significantly improving the efficiency of adding the liquid medicine, thereby reducing the downtime of the UAV and enhancing the overall efficiency of the spraying operation.

[0029] In the above technical solution, considering the problem that vibration will occur during the takeoff and landing of the UAV, to solve such problems, the specific operations are as follows: By setting the spring 7, the first strut 3 slides inside the second strut 4 for buffering. The elasticity of the spring 7 can effectively absorb the impact and vibration, reduce the vibration transmission caused by external impact, thereby protecting the structure and its internal components and extending the service life of the equipment. The rubber pads 9 can also absorb the impact and vibration, further improving the stability during the takeoff and landing of the UAV.

[0030] Working principle: When in use, place the medicine box 16 at the bottom of the mounting plate 14, and then start the motor 20 to drive the screw rod 19 to rotate, thereby driving the connecting blocks 22 to approach each other, so that the connecting plate 23 clamps the medicine box 16 from both sides. At the same time, the clamping block 24 enters the card slot 25 to further fix the medicine box 16. Then, control the drone to spray medicine. When it is necessary to fill the medicine water, control the motor 20 to rotate in the reverse direction, so that the clamping block 24 disengages from the card slot 25, and the medicine box 16 can be removed to fill the medicine water.
