ABSTRACT:
A clamping device has a clamp base having a first clamping element. A second clamping element faces the first clamping element, which moves toward the first clamping element and cooperates with the first clamping element to hold an article. A shaft is rotatably provided in the crank base such that it extends substantially at right angles to the directions in which the second clamping member moves. An eccentric is formed on the shaft. A crank lever is supported at one end by a crank holder connected to the second clamp element and fitted at the other end on the eccentric. As the shaft rotates, the second clamping element is moved towards or away from the first clamping element so as to hold the article between the elements or release the article from them.
