Abstract

A portable hole punch (23) contains two arms (1, 2) which are rotated about an axis extending at right angles to the lenght direction of both arms, a stamp (10) and a pad (7) mounted on the arms on one side of the rotation axis. The stamp and pad are moved by a drive mechanism in the arms on the other side of the rotation axis.The punch is mounted in the second arm (2) and can be rotated about an axis (11) parallel to the arm rotation axis. The punch also cooperates with a control mechanism (12) for the pad. The second arm is rotatably secured to the first arm (1) by a link arm (4) so that it can be rotated in a radial direction about the arm rotation axis in order to compensate for angle changes during reciprocal movement of the two arms.
