[0042] The set of connecting assemblies comprises four first connecting assemblies, one first connecting assembly is used for connecting and fixing between one arm 2 and the fuselage 1, the four corners of the fuselage 1 are respectively provided with two locking buckles 13, a first electrical interface 14 and an arm insertion hole 15, a first distance is less than a second distance, the first distance is the distance between the first end of the outer side wall of the locking buckle 13 and the central axis of the arm 2 insertion port, the second distance is the distance between the second end of the outer side wall of the locking buckle 13 and the central axis of the arm 2 insertion port, the first end of the outer side wall of the locking buckle 13 is away from the central axis of the fuselage 1, each first connecting assembly comprises:

[0043] A first electrical connector 16; the first electrical connector 16 is connected with the first electrical interface 14 of the avionics system;

[0044] Two locking buckles 17; the middle parts of the two locking buckles 17 are respectively rotatably installed on the arm 2, the locking ring 18 of the locking buckle 17 is located at the first end, the inner side of the locking ring 18 is an arc structure, the locking ring 18 of one locking buckle 17 is locked and fixed with one locking buckle 13;

[0045] Two elastic members; the two ends of one elastic member are respectively fixedly connected with the arm 2 and one locking buckle 17, the elastic member acts on the locking buckle 17, so that the first end of the locking buckle 17 moves towards the central axis direction of the arm 2.

[0046] The elastic member is a torsion spring 24, the torsion spring 24 is installed on the arm 2, and the elastic action end of the torsion spring 24 acts on the second end of the locking buckle 17.
