ABSTRACT:
A replacement device for clamping heads comprises a plurality of clamping jaws and is provided with pivoting parts, which are pivotably mounted on a carrier. The pivoting parts extend essentially in the axial direction of the device and can engage in holes on the clamping jaws. A radially active force applying device pushes the pivoting parts outwards, causing the clamping jaws connected thereto to be pressed together. In this way, the clamping head can be used in a housing or a machine-tool.
