A pair of pliers mainly includes a first body part having predetermined length, thickness, and shape; a second body part having length, thickness, and shape adapted to work with that of the first body part; and a joint pivotally connecting the first and the second body part together at a predetermined position. The joint is movable within a defined range to enable quick adjustment of jaw opening of the pliers, and is locked in place once it is moved to a desired position.
