Abstract
A wrench has a handle, a first jaw and a second jaw. The first jaw and the second jaw each has a holding face and two sidewalls respectively connected to the holding face at two sides. Each edge between the holding faces and the sidewalls of the first and the second jaws respectively has a guiding portion thereon. The guiding portions are chamfer or fillets. Whereby the distance between the interior sides of the guiding portions, which are connecting to said holding faces, of said first jaw and said second jaw is smaller than the distance between the exterior sides of said guiding portions, which are connecting to said sidewalls, of said first jaw and said second jaw. The guiding portions will enlarge the coupling range of the wrench.
