ABSTRACT:
The invention relates to a clamping device, especially for clamping work tables, fixtures etc. to a base such as the machine table in a machine tool, comprising a holding means (2) having an enlarged head (4) and clamping means (8) which in the clamping position engage the head (4) of the holding means (2) and a clamping mechanism (7) which in its normal condition acts with its full clamping force against the clamping means but which unloads the clamping means when a disengagement force is applied thereto. In accordance with the invention the clamping means consist of clamping hooks (7) which are pivotable between a clamping position, in which they engage the head (4) of the holding means (2), and a disengagement position, in which they completely disengage the head of the holding means, during simultaneous movement thereof in a direction opposite the clamping direction, and reverse.
