Abstract: A tool extension includes a receiving member having a stem and a casing, the stem includes an engaging hole for engaging with a driving tool, and the casing includes an space formed between two plates for engaging with an adapter, the adapter includes a number of radially extended protrusions for rotating and directing toward and away from the stem, the adapter and includes a socket opening formed in each of the protrusions for engaging with various tool elements or fasteners. The casing includes a spring biased projection engaged in one of the plates for selectively engaging with the adapter and for positioning the adapter to the casing.

Abstract: A wrench is configured to interchangeably accept different multi-tool heads. The wrench has tool head mounts located at opposing ends of a body. Connectors or connecting mechanisms are provided for interchangeably accepting tool heads at each mount. The connectors may comprise mounting pins which pass through a passage in the tool head and engage struts of the mounts.

Abstract: A wrench assembly and a method of use are disclosed herein. A wrench assembly for handling one or more work pieces may include a handle, a first drive member connected to a first end of the handle, and a second drive member connected to a second end of the handle. The first and second drive members may each have a plurality of drives configured to engage and transmit torque to one or more work pieces. The drive members may include a spline configuration operable to engage work pieces having different shapes of engagement surfaces. A method of handling a work piece using the wrench assembly may include engaging one or more of the work pieces with the spline configuration of the drive members and transmitting torque to the work piece by applying a force to the wrench assembly.

Abstract: This invention is about a device used for installing a fixing nut on the targeted objects-multiple fixing screw axes protruded from the hub or for separating them from the targeted object or the fixing screw axis in order to fix vehicle's tire wheel to the hub when installing or separating a fixing nut from targeted objects. Based on the idle operation of the operating gear, not based on the visual examination, the invention immediately recognizes the complete installation of a fixing nut. Likewise, this invention is to provide a wrench that maximizes user convenience.

Abstract: An improved die insert for gripping oil field tubular members in tubular handling systems such as power tongs, slips, safety clamps and the like. The die insert has a gripping surface which comprises a backing surface adapted to contact the tubular member. The backing surface may be smooth or it may have a series of teeth formed thereon. The backing surface further has a granulated particle coating applied thereto which forms the gripping surface of the present invention. In a preferred embodiment, the gripping surface will include a refractory metal carbide selected from the group consisting of the carbides of silicon, tungsten, molybdenum, chromium, tantalum, niobium, vanadium, titanium, zirconium, and boron.

Abstract: A wrench includes a core plate made of metal and an outer portion such as rubber encloses the core plate. A driving member and a ratchet mechanism are received in the through holes in the core plate and the outer portion. A hammer piece is connected to a side of the outer portion and a chamber for receiving a bit connector and a plurality of notches for receiving bits are defined in an outer periphery of the outer portion.

Abstract: A multi-socket wrench is described which includes an elongated main member having a thickness dimension with an upper area, a lower area, a first end and a second end; and, at least two elongated wrench units, e.g. four wrench units. Each wrench unit has a thickness dimension and opposing elongated ends and two sockets positioned side by side thereon. One of the at least two wrench units is rotatably attached at the upper area and another of the at least two wrench units is rotatably attached at the lower area of the first end of the elongated main member.
