Propeller, propeller kit, power assembly, power kit and unmanned aerial vehicle

An unmanned aerial vehicle (UAV), comprising a power kit, wherein the power kit comprises:

• a first drive apparatus, a second drive apparatus, a first mounting member, a second mounting member and a propeller kit;
• wherein the propeller kit comprises:
• a first propeller and a second propeller, wherein
• one of the first propeller and the second propeller is a forward propeller, the other is a counter-rotating propeller;
• the first propeller comprises a first hub and at least two first blades connected to the first hub, wherein the first hub is detachably mounted on the first drive apparatus via the first mounting member and is provided with a first fitting portion and a first clamping member on a surface facing the first mounting member, wherein the first hub is positioned at an output end of the first drive apparatus and maintains a distance between the first drive apparatus and the at least two first blades above the first drive apparatus;
• the first mounting member is detachably mounted on the first drive apparatus and is provided with a second fitting portion and a first stroke groove on a surface facing the first hub, wherein the second fitting portion is configured to adapt to the first fitting portion, wherein the first stroke groove is configured to rotationally lock the first clamping member into place;
• the second propeller comprises a second hub and at least two second blades connected to the second hub, wherein the second hub is detachably mounted on the second drive apparatus via the second mounting member and is provided with a third fitting portion and a second clamping member on a surface facing the second mounting member, wherein the second hub is positioned at an output end of the second drive apparatus and maintains a distance between the second drive apparatus and the at least two second blades above the second drive apparatus;
• the second mounting member is detachably mounted on the second drive apparatus and is provided with a fourth fitting portion and a second stroke groove on a surface facing the second hub, wherein the fourth fitting portion is configured to adapt to the third fitting portion, wherein the second stroke groove is configured to rotationally lock the second clamping member into place;
• the first fitting portion does not match the fourth fitting portion, thereby preventing the first propeller from being mounted on the second drive apparatus via the second mounting member;
• and
• the third fitting portion does not match the second fitting portion, thereby preventing the second propeller from being mounted on the first drive apparatus via the first mounting member.
