Abstract

L'invention concerne un dispositif destiné à recevoir un outil électrique portatif. Le dispositif peut être utilisé comme interface entre l'outil électrique portatif et une structure de support ou d'appui et comprend des premier et second moyens de fixation ainsi qu'une contre-structure. L'interface proposée permet à la suspension de l'outil électrique portatif d'être ajustée de manière optimale au centre de gravité de l'outil électrique portatif. De plus, l'interface peut être adaptée à divers outils électriques portatifs et types d'outils électriques portatifs au moyen d'une distance qui peut être ajustée entre le premier moyen de fixation et la contre-structure et d'un diamètre ajustable de la contre-structure. Dans d'autres aspects, l'invention concerne l'utilisation de l'interface proposée pour fixer un outil électrique portatif à une structure de support, et un procédé correspondant.
