An adjustable wrench including a main body, a slide block, a movable jaw and a handle. The main body is formed with a hollow section in which the slide block is transversely slidably disposed. An adjustment bolt is pivotally disposed on the slide block and engaged with the movable jaw. One side of the slide block adjacent to the handle is formed with a dented section. The handle has at least one stop member corresponding to the dented section for abutting against the slide block. When the handle is wrenched, the stop member abuts against and locate the slide block so as to fix the movable jaw. At this time, the fixed jaw and movable jaw can clamp and wrench a work piece. When the handle is wrenched in reverse direction, the stop member is disengage from the slide block, whereby the slide block and the movable jaw are pushed open by the work piece and idle. Accordingly, the adjustable wrench can one-way wrench the work piece.
