摘要

A cylindrical measuring gauge (CMG) (12) with a scale of measurement pushes into one part with its other part, whose measuring point is its edge of entry into the CMG, which attaches to a ball-and-socket joint on a grip (10), starting from a position at right angles to the grip with free movement and limited rotary movement at 180[deg].
