<p>The tool (3) has tool arms (11) comprising side pieces (15, 16), whose common base point are laterally displaced to a tool level (14). One of the side pieces (15) is connected with head parts (8) via elastic deformable connection areas (25), where the head parts are designed as rod-shaped extension units. The side pieces are elastically deformable relative to each other under effect of reaction forces from a work-piece, where the reaction forces act in a tool level (14). One of the side pieces (15) is elastically deformable regarding the head parts and connected with one of the head parts.</p> |
