The insert 30 is inserted into the mounting through hole 211 and the recess 111, and the insert 30 restricts the protrusion 11 and the receiving portion 21 from being separated from each other in the second direction Y, which intersects with the first direction X.
Specifically, in the illustrated embodiment, the first link 10 is mechanically coupled to the propeller 200, the second link 20 is mechanically coupled to the power unit 300, the first link 10 is provided with the protrusion 11, and the second link 20 is provided with the receiving portion 21. It is understood that, in other embodiments, the second connecting member 20 may be mechanically coupled to the propeller 200, the first connecting member 10 may be mechanically coupled to the power device 300, the second connecting member 20 is provided with the protrusion 11, and the first connecting member 10 is provided with the receiving portion 21, and the specific arrangement manner is not limited herein. The above mechanical coupling may mean that the two are fixedly connected directly or indirectly through other components or detachably connected.
It should be noted that the recess 111 may be a through hole or a groove, that is, the protrusion 11 may form a through hole or a groove. In the illustrated embodiment, the recess 111 is a through hole opened in the first direction X in the protruding portion 11, the through hole corresponds to the mounting through hole 211 in the receiving portion 21, and the insert 30 sequentially penetrates through the mounting through hole 211 and the through hole in the protruding portion 11 to restrict the protruding portion 11 and the receiving portion 21 from being separated from each other in the second direction Y.

At present, in the conventional technology, the propeller and the power source component are directly connected by threads, and the screw threads are matched to transmit the pulling force, or a specific structure (for example, an L-shaped clamping hook) on the propeller is matched with a groove on the power source component, and the matching structure of the screw threads and the groove is used for locking the propeller and transmitting the torque and the pulling force. However, in above-mentioned two kinds of modes, the cooperation structure of screw and power source part plays the effect of transmission moment of torsion and locking simultaneously, and its atress is comparatively concentrated, leads to easy wearing and tearing or rupture, and the reliability problem appears easily when the live time is longer, is that the screw probably breaks away from power source part at transmission power, influences unmanned aerial vehicle's security.
