Abstract: In order to improve a clamping and spreading device for the relative movement of two workpieces which have surfaces lying essentially parallel to a common plane, comprising a first holder, to which the first workpiece can be fixed, and a second holder, to which the second workpiece can be fixed, wherein the two holders are movable relative to one another, in such a manner that this can be used in a simple manner comfortable for the operator it is provided for the first holder and the second holder to be connected to one another via a guiding device so as to be displaceable and for the guiding device to comprise an actuating element which is mounted not only on the first holder so as to be movable but is also mounted on the second holder so as to be movable and via which a relative movement of the two holders can be actuated.

Abstract: In order to provide a clamping device with a clamping rail which is guided for displacement in its longitudinal direction and an actuating device which comprises a gripping element, by means of which the clamping rail can be displaced, which has a great ease of operation it is suggested that a first contact element and second contact element be held on the clamping rail, that the clamping rail be displaceable in relation to the first contact element and that the first contact element be rotatable relative to the actuating device.

Abstract: In order to provide a clamping device with a clamping rail (14) guided for displacement and an actuating device (12) which comprises a gripping element (77), by means of which the clamping rail (14) can be displaced, which can be used universally it is suggested that the clamping rail (14) be displaceable via the gripping element (77) in one direction (A) or an opposite direction (B) and that a change-over device be provided for freeing the displacement in one direction (A; B) and blocking the displacement in the opposite direction (B; A).

Abstract: In order to increase the utility of an arm clamp having a guide rail, on which a fixed transverse arm is seated, having a sliding arm which is displaceable on the guide rail and which can be tilted with the latter, and having a pressure application spindle with a pressure piece, which pressure application spindle is displaceably arranged on the sliding arm so that a compressive force can be exerted on a workpiece between transverse arm and sliding arm, a box-like attachment member is provided for the sliding arm, which provides a substantially flat abutment surface for a workpiece, and is so constructed that it can be pushed on the pressure piece of the sliding arm so that the attachment member is held on the sliding arm and a compressive force can be exerted by the attachment member on a workpiece via the pressure application spindle, and wherein the attachment member comprises at least two mutually spaced guide recesses via which it is displaceably mounted on the guide rail.
