The pivoting and extending interchangeable hand tool device disclosed herein may comprise a tool head and a torque arm that pivot relative to one another, a secondary torque arm for extending length and increasing appliable torque, and a “T”-handle for additional support. The pivoting and extending interchangeable hand tool device may further comprise a plurality of tool heads that may be interchanged within the secondary torque arm, and may be provided commercially in a multiple-tool set. The device is designed to overcome the shortcomings in the prior art, which specifically include the ability to work in tight spaces while reducing the loss of torque when pivoting a torque arm, the loss of strength inherent in an extendable torque arm, and the bulkiness of a “T”-handle.

A fire hydrant wrench includes a wrench-head able to fasten to the pentagonal interface of a fire-hydrant and a handle able to be selectively extended or retracted by a user. The wrench includes a cylindrical rod which may be contained by and telescopes within a tubular handle. A cap on a handle-end of the tubular handle prevents the cylindrical rod from leaving the handle in one direction, while a collar affixed externally to the cylindrical rod prevents it from leaving the handle in the opposite direction. The tool-head containing the wrench is affixed to a tool-end of the cylindrical rod which protrudes from the tubular handle in all positions.

A telescopic hand tool has an inner rod and an outer tube slidable relative to the inner rod. The inner rod is formed with at least one rack gear. The outer tube is formed with a positioning hole. A positioning member is provided in the positioning hole. The positioning member has at least one toothed portion. A control sleeve is slidably fitted on the outer tube. The control sleeve selectively presses the positioning member to make the toothed portion engaged with the at least one rack gear, or selectively releases the positioning member to make the inner rod and the outer tube slidable with each other so that the toothed portion is disengaged from the at least one rack gear and selects a desired meshing point with the at least one rack gear in response to the adjustment. Thus, the length of the telescopic hand tool is adjustable in a stepless manner.

A quickly rotary and expandable ratchet wrench includes a drive bar, an operation handle, a rotary head, and an operation ring. The drive bar includes a bar body and a fork arm connected to the bar body. The bar body includes a plurality of retaining recesses spaced apart from each other and a groove passing through each of the retaining recesses. The operation handle includes a retaining element slidable to position in any of the retaining recesses and a restraint element protruding into the groove. The rotary head is pivotally connected to two ends of the fork arm. The operation ring sleeves on one end of the operation handle, and the retaining element is movable in association with movement of the operation ring to be positioned in any of the retaining recesses, and the operation ring is rotatable with respect to the drive bar.

The combination of a driver and fastener that allows a user to insert and remove the fastener by applying larger than normal torque loads to it includes: (a) a fastener with a proximal end handle and a distal end head configured to provide a standard indentation and an additional recess that provides additional surface area that allows larger torque loads to be applied to the fastener, (b) a main driver with a shaft having a central bore, a handle at its proximal end and a head at its distal end configured to allow it to be temporarily inserted into the fastener's head, and (c) an awl driver having an awl shaft with an awl handle affixed to its distal end and its proximal end including a tip configured to allow it to pass through the main driver's bore and be brought into contact with the fastener's head where it is used to cut into the fastener cannula so as to temporarily adhere the awl driver to the fastener.

An example torque wrench is provided. The example torque wrench may include a drive head configured to engage with a tool for rotating a fastener. The drive head may have a drive axis about which the drive head rotates when rotating the fastener. The torque wrench may also include a deflection member coupled to the drive head and an outer body coupled to the deflection member at a first loading point and a second loading point. The torque wrench may also include a first strain gauge coupled to the deflection member between the drive head and the first loading point, and a second strain gauge coupled to the deflection member between the first loading point and the second loading point.

An adjustable length handle having a first handle member, a tubular shaped second handle member and an adjusting mechanism interconnecting the two handle members to shorten or lengthen the handle length. The second handle member has an interior channel that receives the first handle member. An inner surface of the channel is in opposing relation to an outer surface of the first handle member. The adjusting mechanism comprises a longitudinally disposed length adjusting slot and one or more laterally disposed engaging slots in the inner surface that receive an engaging member which extends outward from the outer surface of the first handle member. When in the length adjusting slot, the engaging member allows linear movement of one handle member relative to the other handle member to adjust the handle length. When in one of the engaging slots, the engaging member prevents such linear movement to fix the handle length.

A telescopic tool includes a positioning device mounted between first and second rods. The first rod includes a longitudinal hole extending along a longitudinal axis, a first positioning hole intercommunicating with the longitudinal hole, and a first gripping portion. The second rod is movably received in the longitudinal hole, includes a plurality of second positioning holes, and is movable relative to the first rod along the longitudinal axis to align the first positioning hole with one of the plurality of second positioning holes. A switch controller is movable relative to the first rod and is movably coupled to a positioning member. The positioning member movably extends through the first hole and is releasably engaged in one of the plurality of second positioning holes in response to movement of the switch controller relative to the first rod. A fixing member includes a second gripping portion mounted around the first rod.

A length adjustment structure contains: a body and a grip sleeve. The body includes a wrench extension, a driving head arranged on a front end of the wrench extension, a peripheral groove defined around a rear end of the wrench extension, a first retaining ring retained with the peripheral groove, and an accommodation orifice defined in the wrench extension so as to house a resilient element and a shaft. The grip sleeve is fitted with the wrench extension and includes a connection orifice defined in a front end thereof, a hollow portion therein behind and communicating with the fitting orifice, a surrounding trough arranged around an inner wall of the hollow portion adjacent to the connection orifice so as to accommodate a second retaining ring, and a tilted recess defined on the inner wall of the hollow portion behind the surrounding trough.

A customized tool adapter that allows for a typical wrench to be connected temporarily, but with great stability to a typical ratchet. Such an application is capable of being used with several types wrenches and ratchets, including various sizes, units of measurement and other applications and is generally hexagonal in nature having swaged gripping lips.
