Abstract
A vise grip locking tool which contains jaws that are capable of opening with a flick of the user's wrist. The tool comprises a first handle member, a second handle member, a lower jaw, and an upper jaw. The first handle member is pivotally attached to the lower jaw. The first end of the lower jaw is made up of four mutually interconnected sides having a guided slot extending through it. The upper jaw has an elongated shank that may slide along the guided slot of the lower jaw. A stop is present on the bottom of the shank preventing the upper jaw from escaping the guided slot. The second handle member is pivotally mounted to the lower jaw and includes a releasable lock which is made up of a spring-operated detent which engages teeth on the elongated shank.

An adjustable vise locking tool comprising, in combination:
- a) a first handle member pivotally attached to a lower jaw member having a guided slot, said guided slot extending through a first end of said lower jaw with four mutually interconnected side portions surrounding said guide slot;
- b) an upper jaw member having an elongated shank being slidingly mounted in said guide slot, said shank being continuously surrounded on four sides by said mutually interconnected side portions, which continuously bound said guide slot;
- c) a second handle member pivotally attached to said lower jaw member having a releasable locking means, locking said upper jaw with respect to said lower jaw and allowing a flick of the wrist to open or close said upper and lower jaws, said releasable locking means comprising a spring-operated detent means set angularly for engaging a continuous plurality of teeth on said elongated shank;
- and
- d) a stop fixedly attached to said elongated shank to maintain said elongated shank in said guide slot.
