ABSTRACT:
In order to improve a clamping device comprising a guide rail, a first clamping element supported on the guide rail and having a first clamping surface formed by a pressure member of a clamping spindle and movable in a clamping direction, a slide bracket guided on and movable along the guide rail and fixable by a first wedging element, and a feed device including a second wedging element supportable on the guide rail and a pivotally mounted feed lever lying with its handle between the guide rail and the clamp grip of the clamping spindle, and a second clamping element supported on the guide rail and having a second clamping surface, such that ergonomically it can be installed more expediently on a workpiece, and the workpiece can thereby be finally clamped, it is proposed that the feed lever act with a first pressure member between the second wedging element and the slide bracket such that upon actuation of the feed lever in the direction of the clamp grip of the clamping spindle, the slide bracket is displaceable in the clamping direction relative to the second wedging element.
