ABSTRACT:
The linear measuring device comprises a rail (1) with a fixed measuring jaw (4) and a slide (5) with a movable measuring jaw (6). A holding member (9) with a handle hole (10) is adjustably mounted on the rail (1). The slide (5) has a ring (20) arranged displaceably therein. This ring is connected with a clamping piece (30) via connecting elements (36, 39). This clamping piece, after attaining a predetermined measuring pressure, is brought into the clamped position on the rail (1) and thus permits the maintenance of a constant measuring pressure, the slide (5) being shiftable, with the clamping piece (30) being locked in place, under the action of the spring (32) with respect to the clamping piece (30) whereby the measuring object can be adjusted into the precise measuring position under spring force. The arrangement of handle hole (10) and ring (20) offers the advantage that maximally precise measurements can be quickly performed in correspondence with a scissor-like operation of the device.
