Pair of Pliers with Dual Functions for Snap Ring

A pair of pliers that is switchable between first and second mode, the pair of pliers comprising:

• a handle assembly including a pair of hand grips pivotally connected to each other and two connected ends respectively extending from the pair of hand grips;
• a jaw assembly, which is installed onto the connected ends and adapted to couple to a ring, including a plate having a slider rail and two first jaws joined together, with each first jaw having a channel and a pin which is disposed in and slideable along the channel;
• and
• a drive member, which is provided between the first jaws and operable between an original position and a moveable position, including a positioning shaft slideably disposed along the slider rail of the plate;
• wherein in the original position of the drive member, the positioning shaft can not slide along the slider rail of the jaw assembly and the first jaws cannot move with respect to the plate via cooperation of the pins and the channels;
• wherein in the moveable position of the drive member, the positioning shaft is slideable along the slider rail of the jaw assembly and the first jaws are driven to slide with respect to the plate and the first pins slide along the channels respectively so that the pair of pliers can selectively be the first or second modes;
• wherein while the pair of pliers is in the first mode, the first jaws are closed to each other before operating the hand grips to move toward each other so that user drives the hand grips to move toward each other for pushing a closed ring open;
• wherein while the pair of pliers is in second mode, the first jaws are away from each other before operating the hand grips to move toward each other so that user drives the hand grip to move toward each other forcing two clamped ends of the ring to move toward each other and closing the ring.
