The invention relates to a nasal septum folding stent. The folding stent includes an annular stent body which has a center vent hole can form a conical structure used for being stuffed in and supporting a nasal cavity; a first gap is formed on the sidewall, close to nasal septum, of the annular stent body; the annular stent body is in hinged joint with multiple movable clamping plates stretching into the first gap; the multiple movable clamping plates do circumferential movement on the annular stent body so as to adjust the areas of the multiple movable clamping plates covering the first gap;the first gap extends to the small end face of the conical structure; the movable clamping plates extend to the small end face in the first gap, and are elastic components and in free states; the movable clamping plates externally expose the first gap relative to the annular stent body, and an included angle alpha exists between the extension axis and the axis of the conical structure and does notexceed 30 degrees; and the thicknesses of the movable clamping plates do not exceed 1 mm. Thus, the technical problems that nasal septum clamping plates cannot cover enough nasal septum mucosal areascan be solved through the nasal septum folding stent.
