A device comprises a body with two opposed spaced apart side walls, each side wall having a first end and a second end, with a slot between the side walls. A first holder is mounted between the side walls proximate the first ends and likewise a second holder is mounted between the side walls proximate to the second ends. The holders can pivot at least 270 degrees, and preferably completely rotate, on an axis perpendicual to the planes of the side walls. A first mount is supported by the first holder for removably mounting a first tool on the first holder, and a second mount is supported by the second holder for removably mounting a second tool on the second holder.

A two-stage universal joint includes a sleeve, a driving member and a restricting member. The sleeve defines an axial direction and includes a receiving groove and an assembling portion. The driving member includes a polygonal ball head. The polygonal ball head has a plurality of arcuate portions. The polygonal ball head is inserted into the receiving groove. The driving member is slidable between a first position and a second position relative to the sleeve.

A wrench head comprises a working axis, a first jaw, a second jaw, and a third jaw. The first jaw comprises first-jaw arcuate convex contact surfaces. The second jaw, is coupled with and pivotable relative to the first jaw, and comprises second-jaw arcuate convex contact surfaces. The third jaw, is coupled with and pivotable relative to the second jaw, and comprises third-jaw arcuate convex contact surfaces.

A clamping socket assembly and method includes positioning a fastener body in a collet. The collet has a first end and a second end, wherein the second end receives the body. The first end includes a tool mating member. The collet has a perimeter wall having a plurality of slots extending therein that extend into the second end to define a plurality of wings. A sleeve is positioned on the collet and is threadably coupled to the collet. The sleeve is rotated in a first direction to threadably couple the sleeve to the collet such that the sleeve moves toward the second end and urges the wings into frictional engagement with the fastener body. A tool is extended through the distal end and into the tool mating member. The tool is rotated to rotate the collet and the body.

A wrench includes a tool head, an outer tube unit, a rod unit and a sleeve unit. The outer tube unit includes an outer tube, a tail seat and a biasing member. The tail seat is detachably mounted to the outer tube. The rod unit includes an inner rod telescopically disposed in the outer tube and formed with a plurality of cavities. The biasing member biases the inner rod away from the tail seat. The sleeve unit is slidably sleeved on the outer tube and includes a positioning ball engageable with a selected one of the cavities to prevent the inner rod from moving relative to the outer tube and removable from the selected one of the cavities to allow the inner rod to move relative to the outer tube.

A pivoting head wrench apparatus for use in confined areas includes a handle having a handle top side, a handle bottom side, a handle first end, a handle second end, a handle front edge, and a handle back edge. A first wrench head is coupled to the handle. The first wrench head is pivotably coupled to the handle first end and is sized to a standard metric size. A second wrench head is coupled to the handle. The second wrench head is pivotably coupled to the handle second end and is sized to a standard SAE size.

An angle adjustment structure for pressing a hand tool contains: a first handle, a second handle, a spring washer, a return spring, two pressers, and two fasteners. The first hand includes a contact sheet having a first thickness, a first toothed orifice, and a positioning portion. The second handle includes a groove having a second thickness, two fixing plates, a second toothed orifice, and a trench. A profile of the second toothed orifice is identical to a profile of the first toothed orifice. The return spring is defined the two pressers. A respective presser includes a pressing portion, a slot, a notch, a toothed column, and a fixing portion. A respective fastener is engaged between the second handle and the respective presser to limit the respective presser to operate among the second toothed orifice, the trench, the recess, and the first toothed orifice.

The disclosure relates to a dental screwdriver having a shaft portion made of a smart type alloy that bends with little or no resistance along an arch forming portion thereof and without imparting torqueing forces along a distal front end portion thereof onto which is connected a drive tip designed to interface with an appropriately sized screw. The smart alloy automatically assumes its original shape in the absence of twisting forces on the shaft along the arch forming portion. In an alternate embodiment, assuming the original shape involves applying heat and/or subtle finger pressure. The dental screwdriver may be part of a set of screwdrivers, each having a distal front end portion which is uniquely weighted, sized and/or dimensioned to accommodate different driver tips, handle different torqueing functions, and/or configured to bend to a specific maximum angular arch without permanent deformation. A dental prosthetic having a curved bore cavity is also described.

Fittings that 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 apparatus for adjusting a height adjustable leg for supporting a cabinet, appliance or structure is described. The apparatus includes a foot of a height adjustable leg and a tool comprising a driving member and a torque input for applying torque to the driving member. The foot includes a rotatable foot part with a driven member and a base part to support the rotatable foot part on a floor or supporting surface. The tool and the foot are complementarily adapted to releasably maintain engagement between the driving member and the driven member to allow the driving member to drive the driven member to rotate the rotatable foot part about a longitudinal axis of the leg for height adjustment of the leg.
