The invention relates to the technical field of flagpoles, and particularly relates to a tensioning mechanism and a flagpole with a telescopic function using the same. The upper part of the tensioning mechanism is a first connecting column, and the lower part of the tensioning mechanism comprises a second connecting column; a first baffle and a second baffle are arranged on the upper end face and the lower end face of the second connecting column in the circumferential direction of the second connecting column correspondingly; the periphery of the second connecting column is movably sleeved with a limiting ring; the upper end face and the lower end face of the limiting ring abut against the first baffle and the second baffle correspondingly; a first arc-shaped convex block is arranged on the periphery of the second connecting column in the circumferential direction; the other side of the first arc-shaped convex block is connected with the periphery of the second connecting column through a first inclined face; a first groove is formed in the end, connected with the first inclined face of the first arc-shaped convex block, of the second connecting column; a second arc-shaped convex block suitable for being embedded into the first groove is arranged on the inner wall, corresponding to the limiting ring, of the first groove; and a through opening is formed in the end, away from the second arc-shaped convex block, of the limiting ring. The tensioning mechanism is simple in structure, the flagpole is easy to fix after being stretched out and drawn back, and operation is easy.
本发明涉及旗杆技术领域，尤其涉及一种涨紧机构和使用其的具有伸缩功能的旗杆，涨紧机构的上部为第一连接柱，涨紧机构的下部包括第二连接柱，第二连接柱的上、下两端面且沿其周向方向分别设有第一挡板和第二挡板，第二连接柱的外周活动套设有限位环，限位环的上、下端面分别与第一挡板和第二挡板抵靠；第二连接柱外周周向设有第一弧形凸块，第一弧形凸块另一侧与第二连接柱的外周通过第一斜面连接；第二连接柱与第一弧形凸块第一斜面连接的一端形成有第一凹槽，第一凹槽对应限位环的内壁上设有适于嵌入第一凹槽的第二弧形凸块，限位环远离第二弧形凸块的一端设有贯通的开口。本发明的涨紧机构，结构简单，旗杆伸缩后容易固定，操作简单。
