The matching of the second boss 610 and the second recess 521 forms a mechanical locking structure after the plug is inserted into the socket, effectively preventing the plug from being accidentally pulled out due to vibration, shaking or external force during the operation of the wing-body structure of the unmanned aerial vehicle, and ensuring that the power connection between the battery 60 and the mounting seat 50 is always stable and reliable. When the second plug 61 is inserted, the second boss 610 can slide along the edge of the second recess 521, providing clear guidance for the insertion of the plug. This enables the operator to more quickly and accurately insert the plug into the socket, reduces the risk of damage caused by inaccurate insertion, and improves the efficiency of the plug-in operation. The specific shape and position of the second boss 610 and the second recess 521 can prevent misinsertion. Only when the direction of the plug is correct, the boss can be matched with the recess and inserted, avoiding safety problems such as circuit short circuit and equipment damage caused by incorrect insertion direction.
[0034] The first propeller balancer 31 comprises a first fixing member 310 mounted on the shaft core 21, first swing arms 311 mounted on both sides of the first fixing member 310, and a first balance weight 312 connected to the free end of the first swing arms 311.

When the propeller is unbalanced during rotation, the first propeller balancer 31 and the second propeller balancer 32 can quickly respond. Because the balance weight is located at the free end of the swing arm, it is very sensitive to changes in unbalanced force. Even a small imbalance can cause the swing arm to swing, causing the balance weight to displace accordingly to adjust the balance state of the propeller. During the flight of the wing-body structure of the unmanned aerial vehicle, various factors may cause the balance state of the propeller to change, such as airflow disturbance, load change, etc. The structural design can adjust the imbalance in real time to ensure that the wing-body structure of the unmanned aerial vehicle always maintains a stable flight attitude.
