A rotatable fastening device disclosed in the present disclosure includes a rotating seat and an impact element. The impact element is one-way pivoted at the rotating seat. The rotating seat is rotated along a rotation axis and detachably connected between a driving tool and an element to be rotated. The weight and kinetic energy of the impact element will provide a one-way tangential impact force around the rotation axis with of rotation.

A rotatable fastening device includes a rotatable base and an impact member. The rotatable base rotates along a pivoting axis, and the rotatable base is removably connected with and driving a rotatable member. The impact member is removably connected to an outside of the rotatable base, and the impact member has at least one gravity unit projected outwardly therefrom. The gravity unit is driven by the rotatable base to rotate around the pivoting axis for generating a tangent impact force.

The multi-function tool described herein includes a case, a drive ratchet installed in the case, a threading die held within the case, a file attached to the case such that a working surface of the file is exposed, a wrench tool removably secured to the case by a wrench retaining feature formed in the case, socket tools removably secured to the case by socket retaining features formed in the case, and a bar extension tool removably secured to the case by a bar extension retaining feature formed in the case. The ratchet has a fitting exposed at the top of the case, and a toggle switch exposed at the bottom of the case. The bar extension tool is compatible with the socket tools, the fitting of the ratchet is compatible with the socket tools, and the fitting of the ratchet is compatible with the bar extension tool.

A preferred embodiment of the present invention is directed to a rotary tool and, more specifically, to a pneumatic wrench that can be used as both a standard socket wrench and as a fastening tool for setting HI-LOK-type fasteners commonly used in the aviation industry. In a preferred embodiment, the wrench comprises a handle and a rotational member connected to the handle, said rotational member configured for exerting torque about an axis of rotation in one direction only. The wrench further comprises a hole extending through the rotational member along the axis of rotation. The hole has two ends each having female threads. One end has right-hand threads and the second end has left-hand threads. The tool further comprises socket adaptors having right-hand and left-hand male threads for attaching the adaptors to the wrench. Each socket adaptor also has a through hole that aligns with the hole in the rotational member. The holes allow a hex key to be inserted through the wrench so that the wrench can be used to fasten HI-LOK fasteners. The simple design of the tool results in a wrench that is easy to use and relatively inexpensive to manufacture. A preferred embodiment of the invention further comprises a method of using the wrench.

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.

A tool has a body with an axially extending cavity containing partly cylindrical receptacles. Each receptacle has an opening facing inward toward the axis. A partly cylindrical cam portion of a jaw fits within each of the receptacles. Each jaw has a workpiece engaging portion protruding from the body. Each of the cam portions has a pair of flat flanks that protrude inward from the opening of one of the receptacles. The flat flanks intersect each other at an inner corner. Each flank abuts one of the flanks of another of the cam members. Each of the engaging portions has an outer surface configured to engage a hole within the workpiece. An increment of rotation of the body relative to the jaws causes the inner corners of the flanks to move outward from the axis and the outer surfaces of the engaging portions to move from a contracted position to an expanded position.

A telescopic tool includes a positioning device mounted between first and second rods. The first rod includes a first positioning hole, and a first gripping portion. The second rod includes a plurality of second positioning holes, and is movable relative to the first rod to align the first positioning hole with one of the 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 positioning hole and is releasably engaged in one of the 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 resilient biasing member is pivotally connected to the first rod and pressing against the positioning member.
