The main body has a first receiving, chamber, a second receiving chamber and a third receiving chamber which is communicated with the first receiving chamber and the second receiving chamber. One end of the second receiving chamber is formed with a larger diameter section, and the other end of the second receiving chamber is formed with a small diameter section. The driving member is rotatably assembled within the receiving chamber. The restricting member is disposed in the third receiving chamber and limitable to a rotational direction of the driving member. The switching member is rotatably disposed within the second receiving chamber and includes a rotatable member and a projection which extends from the rotatable member. The rotatable member is received in the larger diameter section and the projection is received in the small diameter section.

Abstract: A wrench support rack including a base, and at least one clamp assembly attached to the base and comprising a vertical stop spaced apart from a push member. The space in between the vertical stop and the push member forms a groove configured to receive a stem of a wrench. The vertical stop includes an upper ridge portion configured to engage a stem of a wrench and limit vertical movement of a wrench disposed in the groove. The push member includes an inward protrusion configured to press a stem of a wrench in to the vertical stop and limit horizontal movement of a wrench disposed in the groove.

Abstract: A wrench extension device having an input and output, operably coupled together to transmit torque there between. The wrench extension device further includes a housing, with a first and second gear disposed therein. The first and second gear are operably coupled to one another with a chain. The wrench extension device further includes a rib disposed between the first and second gear. The rib includes a tapered portion that, along with an interior wall of the housing defines a tapered space. A tapered space defined by the tapered portion of the rib and the interior wall of the housing; wherein said tapered space is wide enough to allow a chain link to pass both horizontally and vertically, and wherein the area of said tapered space is large enough accommodate at least one additional chain links when the chain is slack as opposed to when it is taut.

Abstract: A hand tool or wrench with a ratcheting mechanism. The wrench includes a number of components such as an abutting block and a pawl for use in a bistable ratchet operation. The wrench includes a ratchet mechanism that provides stable seating of the components, so that the mechanism is securely retained in a driving mode, as well as enabling a user to select a driving mechanism with ease so as to improve work efficiency.
