Problems solved by technology

[0005] Although the screw can be used to fix the propeller on the motor well, tools are generally required for its assembly and disassembly, which makes the assembly and disassembly of the propeller inconvenient
Although the fixing method through the cooperation of the protrusion and the groove is easy to assemble and disassemble, the cooperation between the protrusion and the groove is easy to loose, which is not conducive to the flight of the aircraft

Embodiment Construction

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0038] In the embodiment of the present invention, the central hole of the propeller cooperates with the rotating shaft of the motor, and the first buckle part of the propeller cooperates with the second buckle part on the cover of the motor. The two ways of cooperation can be fixed by means of interference fit, etc. Therefore, the assembly and disassembly work between the propeller and the motor can be better completed without tools, and the propeller can be b...
