[0027] The quick fixing mechanism 3 includes a slotted fixing block 31. A push block groove 32 is formed inside the slotted fixing block 31. A plurality of first springs 33 are fixedly connected in the push block groove 32. The other ends of the first springs 33 are fixedly connected with a snap top plate 34. A button 35 penetrating from the push block groove 32 to the outside of the slotted fixing block 31 is fixedly connected to the side surface of the snap top plate 34. A ramped convex block is fixedly connected above the snap top plate 34. The convex block above the snap top plate 34 is adapted to the positioning groove 6. When it is necessary to disassemble and repair the internal structure of the machine body, only need to press the two buttons 35 to unlock the snap top plate 34 from the positioning groove 6, and then the upper shell plate 4 can be removed. When the repair is completed and the upper shell plate 4 needs to be installed, only need to align the four rotating shaft limiting holes 5 with the fixed support rotating shaft 2 and press down. Due to the ramp design of the convex block above the snap top plate 34, the first spring 33 is compressed. After the snap top plate 34 is locked with the positioning groove 6, the first spring 33 returns to its initial state.

[0028] The working principle of the present utility model is as follows: In the initial state, the clamping post 10 is inserted into the limit fixing hole 16 to ensure that the first support arm 14 and the second support arm 15 are in a folded state through physical limitation. At the same time, the second support arm 15 maintains a certain tension under the action of the torsion spring 18, but due to the limitation of the clamping post 10, it cannot be unfolded. The third spring 12 is connected to the spring fixing post 11 and the side fixing block 13 through a hook to provide a certain pre-tightening force for the first support arm 14. However, due to the limitation of the clamping post 10, the first support arm 14 remains in a fixed position. The ramped convex block above the snap top plate 34 is locked with the positioning groove 6 of the upper shell plate 4 to ensure the tight connection between the upper shell plate 4 and the lower shell plate 1;

[0029] When it is necessary to unfold the first support arm 14 and the second support arm 15, first, lift the sliding lifting rod 9 upward. The sliding lifting rod 9 drives the clamping post 10 to be pulled out of the limit fixing hole 16 to release the limitation on the first support arm 14 and the second support arm 15. Under the action of the third spring 12 and the torsion spring 18, the first support arm 14 and the second support arm 15 start to automatically unfold. The third spring 12 pushes the first support arm 14 to a proper position and abuts against the spring fixing post 11 for fixation. At the same time, the torsion spring 18 pushes the second support arm 15 to rotate until the positioning card plate 20 abuts against the limit fixing plate 19 to complete the fixation of the second support arm 15;

[0030] When it is necessary to disassemble the upper shell plate 4 for repair, the buttons 35 on the two quick fixing mechanisms 3 can be pressed. The buttons 35 push the snap top plate 34 to compress the first spring 33, and at the same time unlock the ramped convex block above the snap top plate 34 from the positioning groove 6. At this time, the upper shell plate 4 can be easily removed to expose the internal structure of the UAV body for repair;

[0031] After the repair is completed, align the rotating shaft limit hole 5 of the upper shell plate 4 with the fixed support rotating shaft 2 and gently press down. During the pressing process, due to the slope design of the raised block above the buckle top plate 34, the first spring 33 is compressed. When the upper shell plate 4 is pressed down to a certain position, the raised block above the buckle top plate 34 slides into the clamping groove 6 and completes the locking. At this time, the first spring 33 returns to its initial state, firmly fixing the upper shell plate 4 on the lower shell plate 1.

[0032] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent replacements or changes, shall be covered by the protection scope of the present invention.
