The device consists of a stamp housing having supporting elements which are mounted thereon and are constructed as gripping brackets (4, 5), and a plunger (7). The gripping brackets (4, 5) are supported such that they can pivot in such a manner that two lever arms are produced, the upper lever arms (between which two tension springs (12, 13) which run on the sides of the plunger (7) are clamped in) having inclined surfaces for the plunger (7) which tapers in the form of a wedge in the lower region. When it is pressed down, the plunger (7) (which has parallel outer surfaces in the upper region) causes a rotational movement of the two gripping brackets (4, 5) in such a manner that the respectively upper lever arms pivot outwards and the respectively lower lever arms pivot inwards. <IMAGE>
