Abstract

A wrench structure including a wrench head having a fixed jaw, with a movable jaw arranged in a sliding confronting relationship relative to the fixed jaw is arranged, wherein the fixed and movable jaws each include mirror image confronting faces, with each face having a mirror image V-shaped recess to accommodate enhanced securement of a wrench flat complementary surface portion of an associated workpiece for grasping within the V-shaped recesses.

Claims2

Dependent claims

An adjustable wrench, comprising,

a wrench head, the wrench head having a drive worm screw rotatably mounted within the wrench head, with the wrench head including a wrench head end wall, and a fixed jaw fixedly mounted to the wrench head, with the fixed jaw including a fixed jaw wall orthogonally oriented relative to the wrench head end wall, and
a guide slot directed into the wrench head in communication with the wrench head end wall, and
a movable jaw having a follower, with the follower received within the guide slot, and the movable jaw further including a movable jaw wall arranged in a parallel coextensive relationship relative to the fixed jaw wall, and
a first V-shaped recess directed into the fixed jaw wall, and a second V-shaped recess directed into the movable jaw wall, wherein the &irst V-shaped recess and the second V-shaped recess are arranged in a mirror image facing relationship relative to one another, and the drive worm screw is arranged for reciprocation of the movable jaw within the guide slot, and
further including an elongate wrench handle integrally mounted relative to the wrench head, with the wrench handle having a handle end wall, the handle end wall including a polygonal cavity directed into the handle end wall, the polygonal cavity having spaced cavity side walls, and the handle having a handle top wall, and at least one recess, the at least one recess directed into the handle top wall, with the wrench handle formed of a ferrous metallic material, and a screwdriver blade member complementarily received 7ithin the recess, the screwdriver blade member formed of a magnetic material, and the blade member having a blade member head, and the blade member head having at least one semi-spherical recess directed therein, and at least one of said cavity side walls having a detent cavity directed into the at least one cavity side wall, with the detent cavity having a cavity spring and a detent sphere mounted to the cavity spring, wherein the detent sphere is directed into the polygonal cavity from the detent cavity for reception within the semi-spherical recess for selective securement of the screwdriver blade member within the polygonal cavity.
