Description: |
| The sections of the tool are called aligning and adjusting portions in the abstract. The straight and curved slots work to move pins connected to the gripping faces. As the handles close, the gripping faces close around a hexagonal object. A spring opens the handles, enabling a ratchet-like cycle of grip, turn, release, grip.
