ABSTRACT:
A ratcheting tool including a handle formed with an integral yoke at a first end and a tool head coupled to the yoke at a pivot. The tool head has a toothed hub facing rearwardly of the pivot and into the yoke. A locking spool is rotatably carried in the yoke adjacent the toothed hub. The locking spool has a first face, a second face, and a first tooth extending along both the first face and the second face and engaging the toothed hub. The locking spool is rotatable between a first position in which the first face is adjacent the toothed hub, thereby locking the tool head in a selected angular position with respect to the handle, and a second position in which the second face is adjacent the toothed hub such that the tool head is pivotable about the pivot.
