Abstract

A multi-functional jaw wrench combined with self adjusting socket is provided. The multi-functional jaw wrench is comprised of one fixed jaw and one movable jaw at the first end of the handle and a self-adjustable socket that is rotatably attached on the second end of the handle. The self-adjustable socket comprises of many small diameter pins arranged inside of a bore surrounding a six phased rod placed at the center of the bore. The self-adjustable socket is rotatably engaged to a circular gears developed inside of a hole of a socket receiver that is developed on the second end of the handle via a socket head section. Another embodiment of the current invention of the self-adjustable socket receiver can be folded ±90 degrees to align the socket with the handle and enables a user reach a bolts located inside of a structure.
