    摘要: A dual-pawl ratchet wrench mechanism is disclosed having a stop mechanism for limiting over-travel of a reversing lever for selecting drive directions. In one form, the wrench mechanism includes a ball and spring assembly that cooperate with recesses to define proper positions for the reversing lever, and one or more ramps are provided between the recesses to promote tactile feel and to promote the reversing lever being rotated to a proper position. In some forms, the stop mechanism is formed on a stationary portion, such as a spacer or the wrench body, and a portion of the reversing lever. The design simplifies manufacturing, such as by simplifying assembly and minimizing the need for securements. Additionally, the reversing lever is assembled with the mechanism in a manner to improve sealing.

    摘要: A hand tool includes a head that is adjustable to a plurality of positions. The head is pivotally mounted to a tool body at a pivot axis. A bearing structure is attached at the pivot axis by a hub or fastener, about which the head may be adjusted. An actuator is positioned between the body and the head and acts to lock the head in a predetermined position with respect to the tool body. A plurality of radial slots are provided on a cavity or a bearing structure and receive the actuator in order to lock the tool head in a predetermined position relative to the tool body. The adjustable head allows for the tool to be manipulated to engage fasteners in hard to reach areas and also allow an operator to apply extra torque to the fastener.
