Abstract

La présente invention concerne un mécanisme télescopique comprenant trois groupes de composants d'unité télescopique qui sont raccordés les uns aux autres en série, côté-à-côte, et peuvent s'étendre et se rétracter simultanément. Tous les groupes de composants d'unité télescopique sont raccordés en séquence, côte-à-côte, par un bloc de raccordement (2) et forment une structure de cadre polygonal. Le composant d'unité télescopique comprend une pluralité de groupes d'unités télescopiques articulées en séquence tête-bêche. L'unité télescopique comprend deux bras télescopiques (1) qui sont articulés par des parties centrales respectives en se croisant. Tous les groupes de composants d'unité télescopique peuvent se déplacer de manière synchrone de sorte que la stabilité télescopique est améliorée, tout le mécanisme télescopique est sollicité de manière uniforme, et la stabilité de fonctionnement et la stabilité stéréoscopique sont garanties de manière efficace.
