An angled adapter for coupling a tool bit to a tool includes a housing and a transmission assembly positioned in the housing. The transmission assembly is configured to convert an input torque about a first axis from the tool to an output torque about a second axis acting on the tool bit. The second axis is disposed at an angle relative to the first axis. The angled adapter also includes a shank supported by the housing and including a tool coupling portion configured to couple to the tool. The tool coupling portion has an outer dimension. The shank also includes a transmission coupling portion coupled to the transmission assembly, and an intermediate portion extending between the tool coupling portion and the transmission coupling portion. The intermediate portion has a diameter that is less than the outer dimension.

A torque wrench includes a driving device having a connecting rod pivotably connected to a body. The connecting rod is pivotably connected to a head of the driving device and is pivotable between first and second positions. The torque wrench has first and second lever arms corresponding to the first and second positions, respectively. A torque device is mounted to the body and presses against an abutting end of the connecting rod. An adjusting device is movably mounted to the body and is operatively connected to the torque device for setting an initial torque value. A measuring unit measures the initial torque value. An operating unit multiplies the initial torque value by a first or second correction coefficient corresponding to the first or second lever arm to obtain a corrected torque value. A display unit displays the corrected torque value.

Expandable spinal implants, systems and methods are disclosed. An expandable spinal implant may include a first endplate, a second endplate, and a moving mechanism that is operably coupled to the first and second endplates. The moving mechanism may include a wedge, a first sliding frame and a second sliding frame disposed on opposite sides of the wedge, a screw guide housing a rotatable first set screw and a rotatable second set screw opposite the first set screw. The first set screw may be operably coupled to the second sliding frame and the second set screw may be operably coupled to the wedge. The moving mechanism may operably adjust a spacing between the first and second endplates upon simultaneous rotation of the first and second set screws and operably adjust an angle of inclination between the first and second endplates upon translating the first set screw or second set screw.

A locking device for a tool includes a first component and a second component. The first component has a through hole, and an inner wall of the through hole is provided with a first engaging portion. The second component is selectively rotatably connected to the through hole and provided with a second engaging portion detachably engaged with the first engaging portion. The second component can move relative to the through hole to be switched between an unlocked position where the second engaging portion is disengaged from the first engaging portion and a locked position where the second engaging portion is engaged with the first engaging portion, so that the second component and the through hole are selectively rotatable relative to each other.

Various articulating tools for endoscopic placement of fasteners are disclosed. The tool can comprise a multi-angle articulating screwdriver. The tool can have an elongate shaft with an articulating driver head at a distal end. The tool can rotate the articulating driver head to drive fasteners, such as screws, to a surgical site. The articulating driver head can articulate with respect to a longitudinal axis of the elongate shaft to enable the fastener to be driven at various angle. The tool can be coupled to a powered handpiece power and can transmit torque from the handpiece to the driver head.

A ratchet wrench capable of rotating quickly and driving rotation includes a handle, a rotary head, a positioning mechanism, and a sleeve. The handle includes an arm and a bar body. The bar body includes an accommodating slot; the arm includes a through hole. The rotary head is connected to the arm and includes recess portions. The positioning mechanism includes a positioning element, a resilient body, and a block element. The resilient body receives the positioning element and is received in the through hole, the positioning element is correspondingly disposed in any of the recess portions, and the block element is connected to the positioning element. The sleeve receives the bar body and operably drives the block element to slide in the accommodating slot, so that the positioning element is positioned and selectively engaged with any recess portion.

Described are fittings, components, and associated tools for use in coupling pipe or tubing. The described fittings generally include a unitary body having an outer surface and an inner lumen forming a void within said unitary body. The lumen is configured to receive threads for mating with the threads of a female sub end of a pipe or tube. The outer surface includes at least one aperture for receiving a tool that can be inserted within said aperture so as to rotate the fitting about an axis that extends through the lumen of the unitary body. The at least one apertures provide a safe and convenient way to tighten and loosen the fitting during the process of coupling pipe or tubing.

An open-end wrench includes a stationary jaw including an inclined hole, a through hole adjacent to a first end of an interior surface and communicating with the inclined hole, and a forward hook; a handle pivotably secured to a rear end of the stationary jaw; and a moveable jaw including a forward hook; a hollow cylinder extending from a rear portion to dispose in the inclined hole, the hollow cylinder having an elongated slot on a surface and communicating with an interior of the hollow cylinder, and internal threads at an open end of the hollow cylinder; a biasing member disposed in the hollow cylinder, a threaded fastener secured to the internal threads to urge against a first end of the biasing member; and a pin inserted through the through hole and the elongated slot to stop at a second end of the biasing member.

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.

A driving tool is provided, including a tool set and a driving head. The tool set includes a connecting sleeve, an outer sleeve and at least one limitation member. The connecting sleeve has a receiving slot and a driving end. A plurality of protruding ribs extending axially and a plurality of recesses disposed between the protruding ribs are disposed on an inner wall of the receiving slot. The recesses are provided for a polygonal ball head to insert therein. A recessed portion and a protruding portion are disposed on the inner wall. The outer sleeve is slidable between a first position and a second position. When the outer sleeve is at the first position, the limitation member can restrict the polygonal ball head. When the outer sleeve is at the second position, the polygonal ball head is withdrawable from the receiving slot.
