Abstract
The invention relates to crimping pliers (1). The crimping pliers comprise a spring element (7) which is located in the force flow between hand levers (3, 5) and dies (12). The spring element (7) builds a force-displacement-compensation element (8) which provides the option to be able to crimp workpieces with different cross-sectional areas with the crimping pliers (1). According to the invention, the spring element (7) which builds the force-displacement-compensation element (8) is built in the region of the pliers head (4) of the crimping pliers (1). Preferably, the spring element (7) is a spring in the shape of an arc of a circle or a spiral spring (44) which extends in circumferential direction around the die axis (13).
