ABSTRACT:
A pliers having interchangeable and replaceable jaws. Each shank of the pliers have an outwardly projecting stud formed opposite the handle end thereof. A slot is formed in the jaw end of each shank. The slot opens externally of the shank in a direction away from one another. A latch is pivotably mounted in each slot. Each latch has a finger which projects away from the pliers. Each jaw has a recess formed therein, permitting the jaw to be slidably, removably received on a stud. Each jaw further has a notch formed therein having an open end in communication with the recess in the jaw. Resilient means is positioned in each slot for constantly biasing the latch having the finger thereon outwardly of the pliers. When the jaw is slid onto a stud, the finger is received in a respective notch securing the jaw to the stud. A manually-actuatable portion of the latch permits the latch to be depressed against the biasing action of the resilient means, pivoting the finger out of the notch and releasing the jaw. The stud and the recess are inclined inwardly at an acute angle, so that when the jaw is received on the pliers, it is inclined inwardly providing a transverse force component. The jaw is removably mounted on a stud (formed on the shank) with a detent-type of "snap action".
