Pliers for contracting or expanding snap rings include pivotally connected handles spring biased apart. The handles are coupled to movable jaws by pivotable cam plates. The jaws are guided to move linearly toward and away from each other by parallel slide members. The cam plates carry slidable pins engaging first notches in the handles for moving the jaws apart when the handles are brought together. The pins can engage second notches in the handles for moving the jaws together when the handles are brought together. Other pins having stepped stem portions for engaging holes in ends of snap rings are carried by the jaws. |
