Span width extension device for e.g. screw clamp, has two rails, to which two work piece attachment elements are fixed, where elements are displaceably supported on two clamps, respectively, and rails serve for aggression of clamping tool

摘要

The device (10) has two rails (12, 14), to which two work piece attachment elements (20, 36) are fixed, and the elements displaceably supported on two clamps (58, 60), respectively. The rails serve for aggression of a clamping tool, and the two rails are aligned parallel to each other and are positioned in a sub area in a parallel manner. A distance between the elements is determined by a displacement position of the two rails relative to the two clamps. A blocking device (80) is arranged on or in proximity of an end of the rail (12), where the end is turned towards the element (20).
