The invention relates to the technical field of unmanned aerial vehicles, in particular to a quick disassembly propeller and an unmanned aerial vehicle adopting the same. The quick disassembly propeller comprises: a propeller holder, a propeller and a pressing block, wherein the propeller is arranged on the propeller holder, and is fixed in a circumferential direction of the propeller holder; the pressing block is engaged with the propeller holder, and meanwhile, the propeller is clamped between the pressing block and the propeller holder. Moreover, the invention also provides the unmanned aerial vehicle adopting the quick disassembly propeller. In the invention, by circumferentially positioning the propeller through the propeller holder, axially positioning the pressing block and engaging the pressing block with the propeller holder, the assembly and disassembly efficiency of the propeller can be greatly improved, and transportation of the unmanned aerial vehicle is facilitated; the propeller is limited by means of a pressing force, so a clearance between the propeller and the propeller holder is limited and reduced, the flight performance of the unmanned aerial vehicle is not influenced, and the unmanned aerial vehicle has higher safety.
