Gauge for checking linear sizes of mechanical parts

摘要

A gauge for checking linear sizes of mechanical parts including a handle, a nose-piece, an integral body defining two movable arms and fulcrum devices for rotational displacements of the arms, and a support plate coupled to the handle, the nose-piece and the integral body. The support plate has the form of a ring plate with two parts protruding towards the interior for defining two reference surfaces adapted to limit the opening stroke of the movable arm.
