The gear is configured to threadably engage the threaded translating shaft of the translating arm. The threaded translating shaft is configured to be received by and translate through a translating channel of the base. The base also includes a stationary pad, a drive aperture and gear retaining arms. The gear is retained by the gear retaining arms of the base when the gear is threadably engaged with the translating arm within the base.
1. An adjustable crowfoot wrench comprising:
a base including a drive portion, a base fastener engaging portion including a stationary pad, a translating channel, and one or more gear retaining arms, the gear retaining arms arranged at an end of the translating channel;
a translating arm including a translating shaft, a translating fastener engaging portion, and one or more worm gears arranged on the translating shaft, the translating shaft being configured to be received by the translating channel of the base and the translating fastener engaging portion extending parallel to and longer than the stationary pad of the base fastener engaging portion and including two or more pads, the two or more pads being disposed at approximately a 120-degree angle to each other; and
a gear including a threaded aperture, the gear configured to rotatably couple to the one or more worm gears of the translating shaft, wherein the gear is retained on the translating shaft via the one or more gear retaining arms of the base and the translating fastener engaging portion of the translating arm configured to oppose the fastener engaging portion of the base such that a fastener can be retained between the translating fastener engaging portion and the fastener engaging portion of the base.
