Bolt seats are provided on the other two sides of the assembly seat, and a support plate is provided under the bolt seat. The two support plates cooperate with a vertical limiting mechanism provided at the lower end of the assembly seat, and the two movable blocks at the lower end of the support plate are connected to the lower end frame of the two U-shaped brackets through diagonal support rods. The utility model is different from traditional UAVs in that a support plate is provided between the two U-shaped brackets. During flight, the rotating mechanism in the assembly seat will control the two U-shaped brackets to close. When the U-shaped bracket is closed, it can push the support plate through the diagonal support rod, so that the support plate can lift the hoisted object, ensuring the safety and reliability of the inspection flight of the UAV when carrying items.
