ABSTRACT:
An improved wrench for loosening and tightening objects having flexibility in two different planes of movement. The flexible drive wrench consists of an adjustable handle capable of rotating to achieve different angles along with a flexible shaft comprising of numerous steel links. The handle rotates around the flexible links when the release is engaged and locks when the release is disengaged. In addition, the steel links allow for flexibility along another plane of movement. Numerous links are connected together to form a flexible wrench by inserting a stud with a rounded end into the slotted cavity of the next link with a mushroom head steel pin connecting them. To the last link of the flexible wrench is connected a link with an open-end wrench head, closed-end wrench head, ratcheting head, or other fastening tool head for the removal of fasteners such as bolts, nuts, and other fasteners. The combination of the two planes of movement allows for a greater degree of flexibility in reaching small or confined areas with a wrench.
