Abstract

La présente invention concerne un mécanisme destiné à déplacer une plate-forme de travail (20) en utilisant la puissance d’un outil motorisé portable (10) qui comporte une extrémité de sortie (H). Un tube de fixation (30) est fixé à la plate-forme de travail, et un tube de support (40) est disposé de façon rotative dans le tube de fixation. Une barre de torsion (80) est prévue à l’intérieur dudit tube de support et étendue à travers ledit tube. Un support de fixation (50) est fixé sur une extrémité du tube de support pour retenir ledit outil motorisé portable. Une extrémité de ladite barre de torsion est en prise avec l’extrémité de sortie de l’outil motorisé portable, et l’autre extrémité de ladite barre de torsion actionne une roue d’entraînement (60) fixée au tube de support de manière à tourner via un mécanisme de transmission (70) qui est prévu sur l’autre extrémité du tube de support. La plate-forme de travail peut ainsi être déplacée.
