[0002] As one of the most distinctive creations of aviation technology in the 20th century, helicopters have greatly expanded the scope of application of aircraft. Helicopters are typical dual-use products that can be widely used in transportation, patrol, tourism, rescue and other fields.

[0003] After searching (application number: 202222006140.2), it can be learned that a helicopter spraying equipment connection device includes a medicine storage box, a spraying assembly is provided at the bottom of the medicine storage box, a plurality of vertical plates are fixedly installed on the top of the medicine storage box, two fixed seats are fixedly installed on the top of the medicine storage box, and the fixed seats are fixedly connected to the corresponding vertical plates, and two movable grooves are opened on the top of the fixed seat, and stabilizing bars are fixedly installed on the inner walls on both sides of the movable groove, and a hanging rod is slidably installed in the movable groove, and the hanging rod is slidably mounted on the stabilizing bar, and a rectangular rod is fixedly installed between the corresponding two vertical plates, and the hanging rod is slidably mounted on the rectangular rod, and a sliding groove is opened on the hanging rod, and a plywood is slidably installed in the sliding groove.

[0004] In the process of realizing the utility model, the inventors found that the following problems existed in the prior art and have not been solved: the device does not have the function of adjusting the direction and limiting the spray mechanism, which makes it inconvenient to inspect and clear the nozzle in the later stage, and does not have the function of adjusting the width of the slot of the suspension rod. Even after the clamping plate is limited, the suspension rod may still move laterally or even collide. The connection stability is not ideal and needs to be improved urgently. Therefore, we propose a helicopter spraying equipment connection device. Utility Model Content
