During outdoor flight, when the propellers are damaged due to operational errors and need to be replaced, tools are often required for replacement. When the operator forgets to bring loading and unloading tools, it is difficult to disassemble and replace them, making disassembly and assembly more troublesome and inconvenient. At the same time, the application of screw glue will increase the burden of disassembly and the use effect is poor. Therefore, there is an urgent need to improve the technology of the propeller mounting frame structure to improve this equipment.

[0004] To this end, the utility model provides a propeller-wing mounting frame for a drone. Utility Model Content
