The other end of the driven arm is rotatably connected to the driven support. The active arm and the driven arm form an angle, and the swing amplitude of the rotating blade is formed by the lengths of the active arm and the driven arm.

2. The wind power generator noise reduction blade structure according to claim 1, wherein The first adjusting component further includes a tension spring, the two ends of which are respectively connected to the active arm and the driven arm, thereby limiting the included angle between the active arm and the driven arm and restoring the initial angle between the active arm and the driven arm.

3. The wind power generator noise reduction blade structure according to claim 2, wherein The control component further includes a second adjustment component, and the first and second adjustment components have the same structure; both the first and second adjustment components are straddling the extension portion and the rotating blade, and the first and second adjustment components are spaced apart.

4. The wind power generator noise reduction blade structure according to claim 2, wherein The active support and the driven support have the same structure, both including two fixed blocks with a connecting shaft in the middle. The two fixed blocks of the active support are installed on the upper surface of the extension, and the two fixed blocks of the driven support are installed on the upper surface of the rotating blade.

5. The wind power generator noise reduction blade structure according to claim 4, wherein The active arm is connected to the active support by a shaft that is rotatably connected to the active support, and the driven arm is connected to the driven support by a shaft that is rotatably connected to the driven support.

6. The wind power generator noise reduction blade structure according to claim 5, wherein A fixing part is provided on the side wall of the driving arm, and a connecting block is provided on the side wall of the driven arm on the same side. The two ends of the tension spring are respectively connected to the fixing part and the connecting block.

7. The wind power generator noise reduction blade structure according to claim 1, wherein It also includes a support assembly, which includes a support body and multiple hinge parts. Each hinge part has a fixed end and a hinge end. The fixed end is connected to the support body, and the hinge end is connected to the blade assembly.

8. The wind power generator noise reduction blade structure according to claim 7, wherein The hinge portion consists of three parts, which are arranged at equal angles around the support body; the blade assembly also includes a second blade and a third blade, with the first blade, second blade and third blade respectively corresponding to the three hinge portions.

9. The wind power generator noise reduction blade structure according to claim 8, wherein, The hinge end is provided with a mounting groove, which is respectively matched and connected to the first blade, the second blade and the third blade.

10. The wind power generator noise reduction blade structure according to claim 9, wherein The first blade, the second blade, and the third blade are each provided with a mounting block, which is installed in the mounting groove so that the first blade, the second blade, and the third blade are respectively connected to the support assembly.
