[0025] Furthermore, the protective cover 8 can play an anti-collision role. At the same time, the shape of the protective cover 8 is elliptical, so that the rotating blade 7 can move internally with buffering. When the protective cover 8 is hit, the protective cover 8 and the moving block 9 push the Z-shaped block 15 and the sliding frame 6 to move, and the second spring 14 and the third spring 18 set inside can achieve the effect of buffering and shock absorption.

[0026] A card block 10 is fixedly connected to one side of the rotation adjustment block 2, a card slot 12 is opened inside the connecting block 4, a first spring 11 is fixedly connected to the inside of the card block 10, a pressing block 19 is slidably connected to the inside of the connecting block 4, a pressing telescopic rod 20 is fixedly connected to the inside of the pressing block 19, a wire groove 16 is opened inside the sliding frame 6, the lower surface of the drone body 1 is fixedly connected to the supporting shock-absorbing frame 3, the upper surface of the connecting block 4 is fixedly connected to the blocking block 5, the lower surface of the sliding frame 6 is fixedly connected to the Z-shaped block 15, the connecting block 4 and the sliding frame 6 are connected by a third telescopic rod 17, the connecting block 4 and the moving block 9 are connected by a second telescopic rod 13, the rotating blade 7 is arranged inside the protective cover 8, the blocking block 5 is made of rubber, the Z-shaped block 15 is clamped on one side of the moving block 9, and the card block 10 is inserted into the inside of the card slot 12.
