The whole process is automatic operation, which effectively reduces the technical requirements for the mounting personnel. When the mounting assembly is not installed, the throwing assembly is kept in the clamping assembly and the mounting assembly, which also plays the role of in-machine storage, and the rescue materials are externally mounted, so that the scene of in-machine storage and replacement does not need to be considered, the modification of the unmanned aerial vehicle is less, and the operation and maintenance cost is reduced.

[0050] Fast response: The present application shortens the task response time from dozens of minutes of traditional manual operation to minutes through the process of loading preloading and automatic mounting, which saves valuable time for emergency rescue.

[0051] High degree of automation: The present application realizes the full process automation from mounting to releasing, greatly reduces the technical dependence on professional pilots, and supports unattended operation.
