ABSTRACT:
A vise has a housing block formed with a guide defining a longitudinal direction, a fixed jaw secured to the block, a movable jaw displaceable in the direction in the guide relative to the fixed jaw, and a spindle extending in the direction between the jaws along a spindle axis. A support at the fixed jaw has a formation fitting with the fixed jaw and fixing the support and fixed jaw together against relative axial displacement while permitting limited relative pivoting about a fixed-jaw axis generally perpendicular to the spindle axis. Similarly a bearing between the spindle and the support fixes same against relative displacement along the spindle axis while permitting the spindle to rotate relative to the support about the spindle axis and a nut threaded on the spindle at the movable jaw has a formation fitting with the movable jaw for fixing the nut and movable jaw together against relative displacement parallel to the spindle axis while permitting limited relative pivoting about a movable-jaw axis generally parallel to the fixed-jaw axis.
