A wrench, connectable to a standard square shaped extension, has a wrench head with opposed jaw faces which together define a plane that lies perpendicular to the respective jaw faces. A standard square shaped extension socket is affixed to the wrench head, where a standard square shaped extension can be inserted into the standard extension socket, along a direction that is non-orthogonal to the transverse plane. The standard extension socket can be attached to a frame of the wrench head, or to a rotatable guide which controls movement the opposed jaw face which is movable.

A tool extension adapted to couple to a drive lug of a driver and a tool that allows the tool to reach hard to reach places without room for a coupling. The tool extension voids the need for a larger diameter coupling by including a female recess in an end of the tool extension that receives the bit into the shaft itself.

A gripping sleeve is provided, including: a first sleeve, being substantially tubular and having at least one through hole; at least one restricting member, received in the through hole; a second sleeve, sleeved on the first sleeve and being movable relative to the first sleeve, the restricting member being abutted by the second sleeve and being controllably engaged within an annular groove of a body portion of a main body; an elastic member, disposed around the first sleeve and abutting against the first and second sleeves; a restricting mechanism, arranged on at least one of the first and second sleeves and located between the first sleeve and an outer circumferential face of the second sleeve. A hand tool is further provided, including the main body and the gripping sleeve.

The present invention relates to a three-piece wrench comprising: a wrench body with a working head and a shaft, the working head is located at a front end of the shaft, the shaft has a length; a first extension rod with a length; and a second extension rod with a length; the lengths of the first extension rod and the second extension rod are greater than the length of the shaft; combination of the wrench body, the first extension rod and the second extension rod provides various usage lengths of the wrench, so that different connection types can be used to form required lengths according to requirements.

A cabinet leg is provided including a body securable to an underside of a cabinet and a shaft engageable with the body such that rotation of the shaft moves the shaft toward or away from the body. A foot is secured to a lower end of the shaft including a first portion attached to the shaft and a second portion rotatable relative to the first portion. A plurality of openings are provided around the periphery of the foot for receiving a first end of a tool such that teeth on the tool engage with teeth on the first portion. Rotation of the tool causes rotation of the first portion relative to the second portion, thereby rotating the shaft and adjusting the height of the cabinet leg.

A system for treating a bone includes an insertion device for an intramedullary nail. A first end includes a channel extending therethrough so that, when the insertion device is coupled to an intramedullary nail, the channel of the device is aligned with and in communication with a channel of the nail. The system also includes a guide sleeve extending from a proximal end to a distal end and including a first bend extending along a portion of a length thereof so that a longitudinal axis of a distal portion of the sleeve is angled with respect to a longitudinal axis of a remaining portion of the sleeve. In an operative position, the distal end of the sleeve is inserted into the channel of the device and the remaining portion of the sleeve extends toward a lateral side of a bone being treated.

Position indicator tools systems and methods for use with an elongated adapter are disclosed. Tools are configurable to engage the distal end of the elongated adapter include a first member wherein the first member has a distal end and two projection elements positioned in a plane and a channel between the projection elements further wherein at least one of the first members has a notch at a distal end on a channel-facing side, a positioning member formed integrally with the first member wherein the positioning member has a linear marker on a first side, an angled marker on a second side, and a rocker positioned between the angled marker and the channel.

A modular tool bit holder system includes an angle tool bit holder, a flexible shaft tool bit holder, and a connection assembly. The angle tool bit holder includes a housing containing a first input shaft and a first angle gear rotatably drivable about a first axis and a second angle gear and a first bit holder rotatably drivable by the first angle gear about a second axis at an angle to the first axis. The flexible shaft tool bit holder includes a second input shaft rotatably drivable about a third axis, a flexible intermediate shaft assembly bendable into a plurality of curved, straight, and curvilinear configurations, and a second tool bit holder rotatably drivable about a fourth axis, with the flexible intermediate shaft assembly configured to transmit rotation from the second input shaft to the second tool bit holder. The angle tool bit holder and the flexible shaft tool bit holder are operable separately or in combination. A connection assembly is configured to non-rotatably couple the angle tool bit holder and the flexible shaft tool bit holder when they are operable in combination.

Methods for using installation tools are disclosed. Fastener installation tools engage the distal end of an elongated. Two projection elements positioned in a plane on the installation tool and a channel between the projection elements further are positionable to provide a marker for a user during use to achieve an optimal installation location.

The housed socket extension has a high strength tubular housing with a socket extension apparatus which fits within the housing and protrudes from the ends of the housing. Two bearing retaining devices are mounted on the socket extension apparatus, adjacent to the ends of said housing. The first end of the socket extension receives a ratchet wrench or power tool, and the second end of the socket extension apparatus is designed to mate with a socket or tool bit.
