ABSTRACT:
A clamping device which is arranged to clamp a workpiece to a table or stand, and which does not obstruct the clamping region of the table or stand, has a fluid pressure-loaded clamping piston slidably mounted in a main housing with toggle levers on either side thereof bearing against oppositely situated saddle bearings at the sides of the housing. The toggle levers are moved by the clamping piston between an inclined position and an extended position and load a clamping or pulling anchor which is mounted on the housing. The clamping or pulling anchor is pivotally mounted on a clamping lever so that it can swing through a maximum of 180.degree. from a clamping position into a release position in which it is well clear of the workpiece. The anchor is fitted onto a bearing pin, which is disposed in an end, which projects from the housing, of the clamping lever which is pivotally mounted in the housing. The opposite end of the clamping lever rests against one of the saddle bearings of the toggle levers and is guided slidably in the housing.
