发明名称 Wrench Extension Device
摘要 A wrench extension device laterally offsets connection between a socket and a driving tool to facilitate rotation of the socket in tight spaces. The device includes an elongated housing and a first gear rotatably coupled to the housing proximate a first end of the housing. A socket drive is coupled to the first gear for coupling to a socket rotated by the first gear. A second gear is rotatably coupled to the housing proximate a second end of the housing. A receiver extends into the second gear for being engaged by a driving tool wherein the second gear is rotatable by the driving tool. A chain is positioned in the housing engaging the first gear and the second gear wherein rotation of the second gear rotates the first gear.
