In order to meet the different needs of different working conditions, and occupying a small space after folding, it is convenient for transportation or storage.

Abstract

La présente invention concerne un mécanisme de serrage, le mécanisme de serrage comprenant une base (100); une pluralité de pieds de support (20) qui sont adaptés à la base et qui supportent la base; un rail de guidage fixe (30) qui est disposé sur la base; une première partie de serrage (42) qui est disposée sur le rail de guidage fixe; une seconde partie de serrage (52) qui est agencée de façon mobile sur le rail de guidage fixe; et un mécanisme d'entraînement (200) qui comprend une partie pédale (62) et un mécanisme de transmission entraîné par la partie pédale Le mécanisme de transmission entraîne la seconde partie de serrage à se rapprocher de la première partie de serrage de façon à serrer une pièce à usiner; et le mécanisme de serrage comprend en outre un établi (70) qui est raccordé à la base, l'établi comprenant une surface de travail (701) qui est utilisée pour supporter la pièce à usiner. Le mécanisme de serrage présente les fonctions d'un établi à double usage et d'accessoires de serrage, et peut fournir une force de serrage et une zone de serrage plus grandes, tandis que la surface de travail fournit simultanément une zone de traitement suffisamment grande.
