ABSTRACT:
An adjustable wrench having at least one size-adjusting block on its head is disclosed. The adjusting block includes an eccentric fitting member that is, an eccentric fitting column or an eccentric fitting hole. The eccentric fitting means is eccentrically provided on the block such that the horizontal distances between the fitting member and the side surfaces of the block are different from each other. With the eccentric fitting member of the size-adjusting block, the grip size of the wrench head is easily adjusted by simply changing the fitting direction of the block relative to the head. The wrench head of this wrench may be integrally formed with the wrench handle or separately formed from the wrench handle.
