Abstract

A variable seatpost with a limiting structure, comprising an outer tube, an inner tube, a telescopic rod and a limiter, wherein: the outer tube is movably connected to the inner tube; the telescopic rod is arranged inside the outer and inner tubes and the axial distance between the inner and outer tubes is adjusted by the telescopic rod; and wherein the limiter has an outer part and an inner part; the outer part is arranged in a positioning groove on the outer circumferential side of the inner tube and is pressed against its inner wall; and the inner part projects radially through the inner tube and fixes the telescopic rod with a pressure part, thereby positioning it and preventing it from being displaced towards the inner tube wall.
