[0032] It should be noted that both the drone body 1 and the lighting 5 are conventional devices known to the public in the existing technology, and their specific structures and working principles will not be described in detail in this article.

[0033] Please see Figures 1 to 5 In this embodiment, each of the two connecting blocks 4 is provided with a moving component for moving the clamping plate 7. The moving component includes two sliding plates 10. The two sliding plates 10 are fixedly connected to the top surfaces of the two clamping plates 7 respectively. A sliding groove 11 is opened inside the connecting block 4. Both sliding plates 10 extend into the sliding groove 11. A fixing frame 15 is fixedly connected to the back of the connecting block 4.
