Clamping device for key-copying machine

摘要

The clamping device has a moving part (1) fitted between first (2) and second (3) fixed parts. The moving part has first (4) and second (5) pressing edges perpendicular to its direction of motion, opposite third (6) and fourth (7) pressing edges of the first or second fixed part. The first and second pressing edges have clamping profiles which differ from each other and are reciprocal to the third and fourth pressing edges. The moving part is screwed only on a threaded spindle (8), which extends between the two fixed parts.
