Abstract
The invention relates to pressing or crimping pliers (). According to the invention a spring device () (which is e.g. embodied as U-shaped leaf spring ()) is used in the crimping pliers. In an equilibrium position () the leaf spring () is trapped between stops (). If the pressing or crimping pliers () are moved from the equilibrium position () in closing direction the leaf spring () is biased by a follower () such that the leaf spring () generates an opening force. In reversed direction the opening movement of the pressing or crimping pliers () from the equilibrium position () leads to a bias of the leaf spring () by a follower () such that the leaf spring is able to generate a closing force. According to the invention it is possible to provide that the pressing or crimping pliers () automatically and elastically open when reaching the closed position. Furthermore, a workpiece inserted into the pressing or crimping pliers () is clamped by a closing force and secured in this way.
