Optionally, the outer surface of the connecting part can be provided with a threaded connecting part, so that the spraying system can be conveniently and detachably connected, and the operation is convenient and fast. The outer diameter of the portion of the second fitting member 28 for connection with the second mounting portion 27 can be reduced as appropriate to save material.

The embodiment of the application further provides an agricultural plant protection unmanned aerial vehicle's suit, and this suit includes the box structure. Or the suit includes an agricultural plant protection unmanned aerial vehicle. Or the suit includes box structure and agricultural plant protection unmanned aerial vehicle. It should be noted that, the descriptions about the box structure and the agricultural plant protection unmanned aerial vehicle in the above embodiments and the implementation modes are also applicable to the set of the agricultural plant protection unmanned aerial vehicle in the present embodiment.

The utility model provides an agricultural plant protection unmanned aerial vehicle's suit adopts above-mentioned box structure, through the first clearance that forms between valve body and box to make the valve body can be mobile for the box when pegging graft with the disk seat, reduced the fit error between valve body and the box, thereby improve the sealed effect between valve body and the disk seat. Adopt foretell agricultural plant protection unmanned aerial vehicle, through the second movable gap that forms between disk seat and fuselage, so that the disk seat can for when pegging graft with the valve body of box structure the fuselage is mobile, has reduced the cooperation error between disk seat and the fuselage to improve the sealed effect between disk seat and the valve body.

Although the present application has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the application, and all changes, substitutions and alterations that fall within the spirit and scope of the application are to be understood as being covered by the following claims.
