Abstract

A pair of pliers includes a handle member having an intermediate portion slidably engaged in an intermediate portion of another handle member which has a rack located close to the handle end. A pawl is pivotally secured on the handle member for engaging with the rack so as to secure the intermediate portions of the handle members together when the jaw ends are engaged with the workpiece. The intermediate portions of the handle members have no slots such that the strength of the handle members can be greatly increased.
