[0033] The implementation principle of the small telescopic folding wing unmanned aerial vehicle wing of the embodiment of the application is as follows: when folding and storing, the side wing plate 4 is flipped to cooperate with the connecting shaft, forcing the reset torsion spring 23 to retract so that the outer wall of the side wing plate 4 abuts against the outer wall of the wing plate main body 3. Then, the fixed plate 6 is pushed to cooperate with the synchronous slot and the synchronous block to drive the butt joint block 7 to slide into the inner side of the butt joint slot. At this time, the reset spring 10 is compressed. The fixed plate 6 is continuously pressed to make the butt joint block 7 and the locking block 11 partially contact. The contact between the two sets of inclined surfaces can make the locking block 11 and the first movable rod 8 rotate and deviate. At the same time, the fixed spring 13 is also stretched. After the inclined surface on the butt joint block 7 contacts the slope on the convex plate 15, the convex plate 15 is forced to retract into the retraction slot. After the convex plate 15 is aligned with the abutment groove, the abutment torsion spring 17 rebounds to drive the convex plate 15 to unfold in the abutment groove.

The convex plate 15 abuts against the inner wall of the abutment groove. The folding and storage of the side wing plate 4 and the wing plate main body 3 is completed. Then, the locking bolt 19 is removed, and the wing plate main body 3 and the side wing plate 4 are folded to be on the same straight line by cooperating with the rotating shaft. At this time, the first threaded hole on the upper connecting seat 2 and the second threaded hole on the lower connecting seat 2 are aligned. After the locking bolt 19 is screwed into the inner side of the first threaded hole and the second threaded hole, the wing plate main body 3 and the side wing plate 4 can be locked again. When the unmanned aerial vehicle main body 1 needs to be used, the first movable rod 8 can be rotated by the finger contacting the groove on the outer wall of the torsion plate 12 to cooperate with the limiting plate 18 and the limiting slot. The locking block 11 actively stretches the fixed spring 13. In this way, the convex plate 15 can be separated from the abutment groove. At this time, the fixed plate 6 can be driven away from the side wing plate 4 by the reset spring 10. The first fixed part 16 and the second fixed part can strengthen the positioning effect of the fixed plate 6 after being reset. When the lock is released, the two reset torsion springs 23 cooperate with the connecting shaft to drive the side wing plate 4 away from the side surface of the wing plate main body 3 and tightly abut against the end surface of the wing plate main body 3. The electric telescopic rod 20 can be started to drive the extension wing plate 22 to extend out according to actual needs. The cover plate 21 can be removed by rotating the mounting bolt, and personnel can maintain and repair the electric telescopic rod 20.
