An adjustable wrench including a fixed jaw, a movable jaw, a handle, a shaft member and a stopper pin. The front end of the handle is pivotally connected with the fixed jaw. When the handle is reciprocally pivotally swung, the stopper pin is driven by the handle to reciprocally move toward the stopper section or away from a stopper section of the shaft member. Also, by means of the spring fitted on the shaft member disposed in the main passage of the fixed jaw, after the movable jaw is slightly opened, the movable jaw will be immediately restored to hold the bolt or nut. Therefore, the bolt or nut can be continuously wrenched at one time without troublesome operation. The adjustable wrench has fewer components which are easier to process and assemble.
