1. An adjustable wrench with a strength enhancing structural design comprising:
a body including a grip end a user grasps when operating at a first end thereof and a driving head at a second end thereof, with the driving head including a fixed jaw; and a movable jaw for clamping an object to be driven with the movable jaw including a holding end, a base, and a neck extending between the holding end and the base, with the holding end including two sloped surfaces, with the neck and the base of the moveable jaw engaging and operably movable in a groove formed in the body, wherein the holding end is disposed outside the groove, with the groove including two lateral walls facing oppositely and spaced from each other, with each of the two lateral walls including a first surface and a second surface, with the first surfaces of the two lateral walls facing oppositely and separated by a space, with the first and second surfaces of each of the two lateral walls having a common edge and a first included angle less than 90 degrees, with the two sloped surfaces corresponding to and abutting against the second surfaces of the two lateral walls, with the groove further defining a receiving area including an inner periphery connected between the first surfaces of the two lateral walls opposite to the second surfaces, wherein the base of the movable jaw is received in the receiving area of the groove, does not abut against the inner periphery of the groove and does not contact the inner periphery of the groove when the movable jaw is in a neutral position thereof, and wherein the base of the movable jaw received in the receiving area of the groove abuts against the inner periphery of the groove when the adjustable wrench is driving the object and when the two lateral walls are subject to elastic deformation. |
