| 摘要 |
A clamping device is described with a body, which has a substantially U-shaped cross-section, and at least one slide which can be shifted in the body by a screw spindle and which has at its upper side a plurality of fixing recesses arranged along the slide longitudinal direction with a mutual centre-to-centre spacing for selective engagement of a corresponding fixing projection of a jaw which can be repositioned and a plurality of threaded bores for fixing screws of the jaws. A plurality of cover sheets are provided on the upper side of the slide and they are slidably guided on the slide in its longitudinal direction and have a length which corresponds to the centre-to-centre spacing (pitch) of adjacent fixing recesses. The number of cover sheets corresponds to the number or centre-to-centre spacings (t) and the cover sheets can slide over the region of the currently unused fixing recesses and threaded bores.
