ABSTRACT:
Self-adjusting pliers for single-handed manual manipulation will automatically adjust to positions of positive gripping and holding of any size workpiece within the size range defined by the maximum opening between the jaw portions of the pliers, which jaw portions respectively extend parallel to jaw portion axes. Upon closure from the maximum opening, parts first undergo a sliding action along an axis until the workpiece is engaged and then a pivoting action. The plier handles have bearing surfaces inclined at angles in predetermined ranges to the sliding axis and to the jaw portion axes to facilitate shifting from the sliding action to the pivoting action.
