A wrench is composed of a fixed member and a movable member fastened pivotally with the fixed member such that the second clamping portion of the movable member and the first clamping portion of the fixed member can cooperate. The fixed member is provided with a pivoting slot in which the second pivoting portion of the movable member is pivoted so as to enable the first clamping portion of the fixed member and the second clamping portion of the movable member to work together to hold and turn a relatively small and thin nut, bolt, etc.
