Claim:
1. Pliers comprising: a pair of arm members, at least one of which comprising two spaced apart, generally planar, parallel arm plates; a pair of handles connected to each other for movement of the arm members towards and away from each other; at least one interchangeable working jaw detachably supported in between the arm plates of the arm member; and at least one control mechanism including a retaining spacer positioned in between the arm plates of the arm member, a driving member movably disposed in between the arm plates of the arm member and having an end knob exposed outside the arm member, and a spring biased between the retaining spacer and the driving member, the driving member includes a rod body having the end knob, and an engaging portion extending from a side of the rod body for engagement with the working jaw, and the spring is mounted around the rod body and biased between the retaining spacer and a shoulder of the rod body; wherein the control mechanism is arranged in a manner that pressing of the end knob of the driving member drives the driving member to displace with respect to the arm member in a direction substantially vertical to the arm member between a locking position where the driving member is engaged with the working jaw for stopping the working jaw from departing from the arm member, and a releasing position where the driving member is disengaged with the working jaw to allow detachment of the working jaw from the arm member.
