[0026] In one embodiment, two circular rods 15 are fixedly installed between the front side of the inner wall and the rear side of the inner wall of the circular shell 4. The two circular rods 15 are symmetrically arranged. The outer sides of the two circular rods 15 are movably sleeved with circular sleeves 17. The outer sides of the two circular sleeves 17 are fixedly installed with protective covers 5. The two protective covers 5 are movably contacted with each other on the sides close to each other. The outer sides of the circular rods 15 are sleeved with torsion springs 16. One end of the torsion spring 16 is fixedly connected to the outer side of the circular rods 15, and the other end of the torsion spring 16 is fixedly connected to the inner wall of the circular sleeve 17. When the cylinder 7 pushes the push plate 8 to move downward, the transparent shell 9 pushes the two protective covers 5 to rotate in opposite directions, and the protective covers 5 drive the circular sleeves 17 to rotate. At this time, the torsion spring 16 is twisted to release the protection of the camera 19.

[0027] In one embodiment, a limit plate 18 is fixedly installed on the left and right sides of the inner wall of the circular shell 4, and the lower surface of the limit plate 18 is in active contact with the upper surface of the protective cover 5. The protective cover 5 is limited by the set limit plate 18.

[0028] In one embodiment, a circular groove 10 is opened at the bottom end of the circular column 2, and a damper 11 is fixedly installed on the top of the inner wall of the circular groove 10. A spring 12 is wound around the outer side of the damper 11, and the top of the spring 12 is fixedly connected to the top of the inner wall of the circular groove 10.

The U-shaped legs 3 are cushioned by the combined action of the damper 11 and the spring 12, making it easier to cushion the landing of the UAV body 1.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
