A hand tool assembly includes a rod and a handle which is pivotably connected to the rod, and a control unit which is movable along the rod. When the rod and the handle are located linearly, the control unit is moved to a position where the rod and the handle are secured linearly. When the handle is perpendicular to the rod, the control unit is moved another position where the handle is secured perpendicularly to the rod. The rod and the handle are able to be connected with different hand tools.

A foldable and retractable ratchet wrench comprised of a inch driver end that manually folds down when not in use; a inch fixed driver end; a ratchet arm that folds and locks to various angular positions; an exterior, knurled handle that pivotally folds outward and a cylindrical hollow tube embodiment that extends and retracts from the solid arm. The inch square driver end is housed within a horizontal square slot provided at an extending shank portion of the ratcheting gear. The inch square driver end swivels up substantially at right angle from the plane of the ratcheting head. The ratchet wrench's outer pivoted handle folds outward and is pivoted by a pivotal pin substantially at right angle. The slideable sub-tube arm is guided by a pin that rides along a longitudinal slot of said slideable sub-tube arm for various torque needs and is secured by a spring induced detent ball that seats vertically within the solid arm. The entire ratcheting arm swivels from a substantial at right angle to varied angles for ease in limited working spaces.

A circular, cylindrically shaped tool handle holds multiple sizes of tools. The handle includes one or more holding slots each positioned on the outer surface into which tools are inserted and held. Each holding slot includes one or more contoured compartments in which tools rest when engaged with the handle. Each contoured compartment is of a size and dimension which corresponds to one or more tool sizes. Each contoured compartment is formed about a corresponding receiving hole. A lock is positioned over the contoured compartment to irremovably confine the short leg of the hexagonal wrench within the contoured compartment. Hexagonal shaped tools other than wrenches are able to be used with the handle of the present invention such as screwdrivers and socket wrenches. A tool container stores the tools and the tool handle.

A locking, reversible blade, screwdriver is provided. The screwdriver incorporates a reversible blade; one end is a flat blade for latches or any application that requires a durable flat blade screwdriver, the opposing end is a drive bit holder which could be a magnetic bit holder, C clip bit holder, ball type bit holder etc., or any combination which will accept a variety of drive bit types. The blade can be inserted into the handle with the desired end exposed, where it is secured in place with a ball lock. One hand digital intervention releases the blade. A threaded removable end cap at the opposite end of the handle exposes a selector. This selector, when rotated allows access to one of several tubes holding drive bits for the bit holder end of the blade. The end cap has a wide comfortable flat base with a perimeter recess which acts as a finger grip and the flat base allows the screwdriver to sit on its end for one handed fastener loading on a drive bit.

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 tool with adjustable configurations comprises a handle, an element, and a transformation mechanism. The handle extends along a first reference axis. The element extends along a second reference axis and includes a non-circular engagement hole. The transformation mechanism comprises a first slide seat with a first slide groove having first and second engaging portions, and a toggle button simultaneously engaged with the engagement hole and first slide groove. The toggle button has a third engaging portion that maintains engagement with the engagement hole while being switchable between multiple positions including: a transformation position allowing element rotation, a first fixed position maintaining the second reference axis parallel to the first reference axis, and a second fixed position maintaining the second reference axis perpendicular to the first reference axis.

A grip assembly includes an upper control module, a connecting member connected with the upper control module, and a lower control unit connected with the connecting member. The lower control unit is arranged opposite to the upper control module. The upper control module includes an upper control member, multiple upper locking members, multiple upper springs, multiple upper retaining members, an upper mounting member, an upper coupling member, and an upper elastic member mounted in the upper mounting member. The lower control module includes a lower control member, multiple lower locking members, multiple lower retaining members, a lower mounting member, a lower coupling member, and a lower elastic member. Thus, the grip assembly that allows a user's holding and allows a quick rotation of a T-shaped wrench.
