Abstract
An improved micrometer, characterized by presenting as an element of measurement or verification an opening limited by two inclined planes forming a very acute dihedral angle portion, the device having a free stem slidable longitudinally in the direction of the bisector of the dihedral angle, whose stem on the part of the handle of the apparatus has a signal that travels in the displacements of that a fixed scale on the handle and said rod is pushed out by means of a suitable spring, making measurements or checks by entering the piece to be measured by the aforementioned opening up to its introduction limit, in whose position the respective measurement will be indicated on the graduated scale.
