Abstract

A pliers-type gripping tool includes a pair of gripping jaws, a pair of pivotally connected hand grip levers for operating the gripping jaws between an open separated condition and a closed gripping condition, and an adjusting device for varying one of the physical operating properties of the tool. In one embodiment, the hand grip levers are sectional, and the adjusting device includes an angle setting arrangement for determining the angular relationship of the sections, thereby to permit use of the tool to engage an object at a relatively inaccessible location. In a second embodiment, at least one of the levers includes a metal lever body member partially enclosed by a synthetic plastic shell member. An adjusting device controls the lateral relative positions of the lever body and shell members to adjust the effective thickness of the hand grips to correspond with the size of the hand of the user.
