<p>A ratcheting tool (100) including a handle (130) formed with an integral yoke (132) at a first end and a tool head (110) coupled to the yoke at a pivot (120). The tool head has a toothed hub (112) facing rearwardly of the pivot and into the yoke. A locking spool (150) is rotatably carried in the yoke adjacent the toothed hub. The locking spool has a first face (152), a second face (156), 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 (152) is adjacent the toothed hub (112), thereby locking the tool head (110) in a selected angular position with respect to the handle (130), and a second position in which the second face (156) is adjacent the toothed hub (112) such that the tool head (110) is pivotable about the pivot (120).</p> |
