The present invention discloses a pair of adjustable pliers comprising a first handle having a first gripping part arranged at the front end thereof and a second handle having a second gripping part arranged at the front end thereof. The first gripping part and the second gripping part forms a jaw span, and the first handle and the second handle are arranged in an intersectional manner and relatively fixed via a connecting mechanism, characterized in that, the second handle is provided with an elongated rack slot at a position of the connecting mechanism and the rack slot is provided with a toothed rack on a inner side part thereof. The connecting mechanism comprises a toothed block and a link mechanism, the toothed block is arranged inside the rack slot and engaged with the toothed rack of the rack slot, and the link mechanism connects with the toothed block, drives the toothed block to rotate and disengages from the rack slot. Thus the first handle is able to move relative to the second handle along the rack slot through the movement of the connecting mechanisms, wherein, the teeth of the toothed rack are one-way ratchet teeth. |
