ABSTRACT The invention relates to a front jaw (1) with a housing (2), in which is housed a release spring (40). The release spring (40) loads a pull rod (10) extending through the release spring, which pull rod acts onto the shorter lever arms (36) of two toggle levers (35) through a release plate (13), which toggle levers are pivotal about vertical axes (34) on a bearing part (20) and the longer lever arms of which toggle levers are designed as sole holders (37). The bearing part (20) has a through opening (21) for the pull rod (10) and has at its lower end section a rearwardly directed projection (31) for abutment against the release plate (13). The release plate (13) has according to the invention in its lower section (14) on its side facing the bearing part (20) a control surface (15) which, when viewed in a longitudinal cross section, extends upwardly and forwardly. The rearwardly directed projection (31) on the bearing part (20) rests at least pointlike on the control surface (15) when an upwardly directed force engaging the sole holders (37) occurs.
