The fixing bolts 12 are designed to cooperate with the adjusting sleeve 13 and the nut 15 to fix the connecting block 10 and the swing arm 7. The adjusting sleeve 13 is fixedly connected to the outer side of the fixing bolts 12.

[0035] The outer side of the adjusting sleeve 13 has multiple prismatic strips, which can effectively prevent the connecting block 10 from rotating. The outer side of the fixing bolt 12 has two slidably connected washers 14. The washers 14 are to make the connection between the nut 15 and the fixing bolt 12 more secure. The outer side of the fixing bolt 12 is threaded with the nut 15. The rear end of the mounting base 1 is fixedly connected with an adjusting component for adjusting the center of gravity of the aircraft. The drive component includes a motor 2 and a drive bar 4. The motor 2 is installed inside the mounting base 1.

[0036] The rear end of the first drive bar 4 is fixedly connected to the drive end of the motor 2. The motor 2 is designed to drive the first drive bar 4, thereby driving the second drive bar 5. The battery 3 is installed inside the mounting base 1. The battery 3 is used to provide energy to the motor 2. The bottom end of the limit seat 8 is fixedly connected to the top end of the mounting base 1. The limit seat 8 is designed to cooperate with the limit post 9 to limit the swing arm 7.

[0037] The outer side of the fixing bolt 12 is slidably connected to the inside of the swing arm 7. The fixing bolt 12 is designed to cooperate with the adjusting sleeve 13 and the nut 15 to fix the connecting block 10 and the swing arm 7. The outer side of the adjusting sleeve 13 is slidably connected to the inside of the swing arm 7. The outer side of the adjusting sleeve 13 has multiple prismatic strips, which can effectively prevent the connecting block 10 from rotating.

[0038] The two washers 14 are in contact with the outer side of the swing arm 7. The washers 14 are to make the connection between the nut 15 and the fixing bolt 12 more secure. The outer side of the adjusting sleeve 13 is slidably connected to the inside of the connecting block 10. The outer side of the adjusting sleeve 13 has multiple prismatic strips, which can effectively prevent the connecting block 10 from rotating. The bottom end of the mounting base 1 is fixedly connected to the grip 19. The grip 19 is made of polyethylene. The grip 19 is designed to make it easier for people to hold the aircraft.

[0039] like Figures 1 to 3As shown, the adjustment assembly includes a long rod 16 and a limiting block 17. The front side of the long rod 16 is fixedly connected to the rear end of the mounting base 1. The long rod 16 is designed to facilitate the installation of the counterweight ring 18. The front side of the limiting block 17 is fixedly connected to the rear end of the long rod 16. The limiting block 17 is designed to limit the counterweight ring 18. The outer side of the long rod 16 is threaded with the counterweight ring 18. The counterweight ring 18 is designed to adjust the center of gravity of the aircraft. The long rod 16 is made of aluminum-zinc alloy. The counterweight ring 18 is made of brass. The counterweight ring 18 is designed to adjust the center of gravity of the aircraft.

[0040] Working principle: When using the flapping-wing aircraft based on the butterfly shape structure, the external controller controls the battery 3, which provides energy to the motor 2. The motor 2 drives the first drive bar 4, which in turn drives the second drive bar 5. The second drive bar 5, driven by the first drive bar 4, drives the drive column 6, which in turn drives the two swing arms 7. The two swing arms 7 will swing continuously in this process under the restriction of the limit seat 8 and the limit column 9.

[0041] When the swing arm 7 swings, it drives the wing 11 to swing through the connecting block 10, thereby driving the entire flapping-wing aircraft to fly. When the wing 11 needs to be replaced, use a wrench or similar tool to separate the fixing bolt 12 and nut 15. At this time, the fixing bolt 12 and adjusting sleeve 13 can be removed from the connecting block 10 and the swing arm 7, and the wing 11 can be replaced. The new connecting block 10 is repositioned with the swing arm 7, and then the fixing bolt 12 and adjusting sleeve 13 are inserted into the connecting block 10 and the swing arm 7. Then the washer 14 and nut 15 are installed to complete the replacement process.

[0042] By engaging the fixing bolt 12 with the adjusting sleeve 13 and the nut 15, the connecting block 10 and the swing arm 7 can be disassembled and assembled, thereby completing the replacement of the blade 11. Different colors and types of blades 11 can be replaced according to the user's preferences, which improves personalization and increases the flexibility and applicability of use.

[0043] When it is necessary to adjust the center of gravity of the flapping-wing aircraft, simply rotate the counterweight ring 18 on the long rod 16 to adjust the position of the counterweight ring 18 on the long rod 16. This allows the counterweight ring 18 to adjust the center of gravity of the flapping-wing aircraft, thereby increasing or decreasing the angle of attack of the flapping-wing aircraft and adjusting the flight attitude of the flapping-wing aircraft.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
