A multi-purpose hand tool system is described. The tool system includes a handle and one or more inserts that are releasably engaged with the handle. The tool system is useful for a variety of applications including use with basin and faucet hardware.

A tool holder device includes a receptacle having two conduits perpendicular to each other, a spindle and a shaft are rotatably engaged in the conduits of the receptacle and have bevel gears meshed with each other for allowing the shaft to be rotated relative to the receptacle by the spindle, a housing is secured to the receptacle, a flexible shank is secured to the spindle, a stem is secured to the flexible shank, a flexible sheath is engaged onto the flexible shank and is secured to the receptacle, and a control ferrule is secured to the flexible sheath, and the stem is rotatably received and engaged in the control ferrule. The flexible shank and the flexible sheath allow the tool holder device to be easily operated by the user in a tiny working space.

A wrench has a first segment and a second segment pivotally coupled together. The second segment is selectively positionable at various fixed pivotal positions relative to the first segment. The first and the second segments engage with a locking device. The first segment has a first joining end forming a first positioning surface and a second positioning surface. The locking device includes a catch selectively engagable and disengagable from the first and the second positioning surfaces. The catch has a body section abutting against the first positioning surface in a direction radial to the axis of rotation when the first segment is at a first fixed pivotal position relative to the second segment. The first body section is abutted against the second positioning surface in a direction radial to the axis of rotation when the first segment is at a second fixed pivotal position relative to the second segment.

A two jaw adjustable wrench having two opposing jaws that adjust inward and outward, one jaw having a left hand thread and the opposing jaw having a right hand thread for ease of adjustment. The user rotates the central knurled wheel in either a clockwise or counterclockwise rotation. The direction of rotation influences the opposing jaws to move inward or outward for various fastener size adjustments.

Opposite end of the ratchet wrench has a universally adaptable and slideable ratchet wrench for accepting universal ¼″ hexagon tool bits such as a #1 and #2 Phillips or slotted screwdriver bits of various sizes. Both tool ends are easily retractable and extendable by sliding either tool forward for use and or retractable when not in use.

The Adjustable and Ratchet Wrench's upper housing half provides two pocket-slots to store the Phillip's #1 and #2 screwdriver attachment and a #1 & #2 slotted screwdriver attachment.

A universal joint includes a first joining structure and a second joining structure movably coupled to each other. The first and the second joining structures are movable relative to each other to an aligned position and an inclined position. The first and the second joining structures include a resilient member disposed therebetween. The resilient member has a first end retained on the first joining structure and a second end retained on the second joining structure.

A power wrench includes a cylindrical housing, an electric motor, an output shaft connected to the motor and a power switching device activated by a trigger located on the housing. The trigger is supported on an annular sleeve element coaxially disposed and rotatable relative to the housing for enabling adjustment of the angular position of the trigger relative to the housing. Irrespective of its angular position the trigger is arranged to axially displace a non-rotatable activation ring to of activate the power switching device. The housing includes an adjustable angle head supporting the output shaft and arranged to be set in alternative angular positions relative to the housing.

A torque wrench comprising a head portion having a socket drive for engaging a fastener to be tightened via a suitable socket and a handle portion having a grip for applying force to the drive via a releasable holding mechanism, wherein the releasable holding mechanism is adapted to allow the head portion to pivot with respect to the handle portion when the torque wrench is used to applied to predetermined torque to the socket drive, wherein the torque wrench further comprises at least one electronic sensor for measuring the torque applied to the socket drive and display means for displaying the measured torque.

Provided are a screw driver system and a screw driving bit. The screw driving bit includes a body having a first end and a second end with a longitudinal axis defined therebetween and an outer surface between the first and second ends. The screw driving bit includes a first circumferential groove and a second circumferential groove that are affixed in coaxially positioned arrangement about the longitudinal axis on the outer surface of the body each having a bottom surface. The bottom surface of the first circumferential groove defines a first outer diameter that is larger than a second outer diameter defined by the second circumferential groove. The guide clamp includes a jaw for holding the screw driving bit. When engaged with the first circumferential groove, the guide clamp prevents rotation of the screw driving bit. When engaged with the second circumferential groove, the guide clamp does not prevent rotation of the screw driving bit.

A swivel joint adapter is for use between a tool handle and tool head such as a wrench head. The swivel joint adapter includes a tongue interposed between forked arms. The tongue and forked arms are able to be selectively swiveled upon simultaneous depression of two opposed release buttons. The release buttons have toothed-wall cylinders which lock with similar walls defined on apertures through the forked arms and tongue. Upon depression of the buttons, the toothed walls of the button disengage by lateral sliding movement from the toothed walls of the forked arms, thereby allowing swivelling of the joint adapter.

A tool for inserting into a cavity is provided. The tool includes a plurality of segments moveably coupled to one another, each segment moveable relative to an adjacent segment between a bent position and a coupled position, the plurality of segments including a first segment, the first segment including: a core formed of a first material; and a shell formed of a second material and comprising or defining a guide feature, a drive feature, a line guide, or a combination thereof; wherein the first material defines a greater stiffness than the second material.
