ABSTRACT:
A modular articulated-lever clamping system having a base flange fittable to a pedestal fitted with a supporting element for supporting sheet metal parts; a control lever operated manually and/or by means of an actuator; a lock lever fittable with a gripping element for gripping the sheet metal parts and cooperating with the supporting element; and a connecting rod connecting the control lever to the lock lever. Respective first ends of the levers are hinged respectively to the base flange by a first and a second hinge element, and the connecting rod is hinged to a transverse appendix of the control lever by a third hinge element; the transverse appendix projects laterally from the control lever towards the lock lever, and is offset with respect to the first hinge element, so that the third hinge element is connected to the control lever in a position which, with respect to the first hinge element, is eccentric both in a direction parallel to the radial extension of the control lever, and at the same time in a direction perpendicular to the aforementioned direction; and the first hinge element is in the form of an eccentric pin for adjusting the center of rotation of the control lever.
