ABSTRACT:
A ratchet box wrench (10) comprising an elongate handle (12). A main housing (14) is at one end of the elongate handle (12). The main housing (14) has a circular cavity (16) therein with a seat (18) and a central aperture (20) therethrough. A geared socket (22) has a central collar (24) with a multiple faced opening (26) extending therethrough. A structure (28) is for rotatably carrying the geared socket (22) within the circular cavity (16) on the seat (18), so that the central collar (24) will extend through the central aperture (20) in the main housing (14). A rotational adjustment lever (30) is on one end of the elongate handle (12) adjacent to the main housing (14) to reverse rotation of the geared socket (22), whereby the multiple faced opening (26) in the geared socket (22) will engage with a multiple faced object, which will be turned by movement of the elongate handle (12).
