A tool for removing a nut includes a housing, a cage, and a canted coil spring. An interior sidewall of the housing defines an orifice that extends from top surface of the housing to a lip. The interior sidewall includes a three-lobed cam and a groove. Each lobe has a lobe center line, a counterclockwise cam inner surface on one side of the lobe center line, and a clockwise cam inner surface on the opposite side of the lobe center line. The canted coil spring is received by the groove of the interior sidewall and the groove of the cage. The canted coil spring rotatably couples the cage to the housing. During nut removal, the housing rotates counterclockwise relative to the cage, causing the jaws of the cage to interface with the interior sidewall. |

1. An apparatus for removing a nut, the apparatus comprising:
a housing, the housing includes,
a top portion having a top portion orifice,an interior sidewall in the top portion orifice that includes,
a multi-lobed cam having a plurality of lobes disposed along the interior sidewall,a groove in the top portion orifice;a housing bottom portion having a bottom portion orifice configured to receive a rotary tool; a cage within the housing and having a top surface, the cage having a bottom portion ending in a terminus and a groove in the bottom portion disposed between the top surface of the cage and the terminus, the cage including a plurality of jaws, in which each jaw includes,
a jaw outer cam surface that is configured to interface with one of the lobes of the cam;a jaw inner cam surface configured to interface with the head of the nut, each jaw cam inner surface including a jaw counterclockwise cam inner surface on one side of the jaw centerline and a jaw clockwise cam inner surface on the opposite side of the jaw centerline; an annular spring configured to be received by the groove of the interior sidewall and the groove of the cage; the housing configured to rotate counterclockwise relative to the cage, the lobes of the cam causing the jaw inner cam surface to engage the nut; and the cage configured to rotate counterclockwise with the housing after engaging the nut. |
