A flex head tool includes a first body and a second body and a retaining device adapted to positioned the second body at various angular positions with respect to the first body. The retaining device includes a retainer and an actuator adapted to move the retainer in a first position and a second position. The retainer and the actuator respectively have a first interacting structure and a second interacting structure abutting each other. The second interacting structure has a first and a second position at which the first interacting structure respectively abuts when the actuator is at a first position and a second position. The first and the second positions of the second interacting structure are at different distances from the end of the actuator.

An adjustable socket assembly includes a collet having a first end, a second end, and a perimeter wall. The second end has a receiving aperture therein. The collet is divided into a plurality a plurality of sections. A sleeve has a bottom end that receives the collet. The sleeve has an interior surface that tapers inwardly and abuts the sections to move toward each other as the sleeve moves toward the second ends of the sections. A biasing member extends through a top end of the sleeve and engages each of the sections. The biasing member is actuated to bias the sleeve downward to close together the sections and engaged the valve actuator. An engagement head is attached to the upper end of the biasing member and engages a tool to rotate the collet.

A tool with a pivoting head is shown. The tool includes a locking mechanism that allows the angular position of the head to be locked securely in place once selected by a user. The locking mechanism may be used with a variety of tools, such as ratchet wrenches, that allow for repositioning of the head relative to the handle of the tool.

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.

An attachment for a portable power tool, in particular a screwdriver machine or drilling machine, wherein the attachment has a drive part with a drive element and an output part with an output element for driving a work tool, wherein the drive element is able to be coupled to a machine output element of the portable power tool in order to drive the attachment and is connected or coupled to the output element via a transmission for driving the output element, and wherein the drive part has, on a drive side, a fastening device for releasably fastening the attachment to the portable power tool for conjoint rotation with respect to an angle positioning axis. Provision is made for the output part to be rotatable about the angle positioning axis relative to the drive part into at least two mutually different angle positions.

A torque wrench has a hollow tubular body. A long rod and a short rod are provided in the hollow tubular body. The hollow tubular body is formed with a first through hole and a second through hole respectively corresponding to the long rod and the short rod. A first limiting unit is provided in the first through hole, and a second limiting unit is provided in the second through hole. The first limiting unit enables to slide into a first gap spaced apart between the long rod and the hollow tubular body to limit the swing range of the long rod, and the second limiting unit enables to slide into a second gap spaced apart between the short rod and the hollow tubular body to limit the swing range of the short rod, thereby improving the accuracy of the tripping torque and making the torque wrench easy to calibrate.

Embodiments of a compliant orthopedic driver are disclosed herein. In some embodiments, compliant orthopedic driver includes a body extending from a proximal end to a distal end along a driver axis; a driver tip disposed at the distal end of the body, wherein the body includes at least one compliant portion configured to allow the driver flex about at least two axes transverse to the driver axis.

A driving tool is provided, including: a rod member, including a first end and a second end which includes two separate connection sections; a swingable assembly, including a swingable member having a third end and a fourth end, a shaft and a ring retainer, the third end extending to between the two connection sections, the fourth end including an assembling portion, the shaft being disposed through the two connection sections and the third end, a first end of the shaft being protrusive out from a first one of the two connection sections, the ring retainer being detachably mounted on the first end of the shaft and blocked by the first one of the two connection sections in an axial direction of the shaft; and at least one driving member, detachably assembled with the assembling portion.

This present invention relates to an extendable wrench and ratchet tool kit comprising a plurality of tool heads, one or more metal shafts or rods, and a metal tube or cylinder including a handle. The extendable wrench and ratchet tool allows an operator to connect any of the metal shafts to the handle at one end and connect any of the tool heads to the shafts at another end. The extendable wrench and ratchet tool kit features a spring-loaded locking mechanism or other similar mechanism to lock the metal shaft or rod at equally spaced grooves in order to selectively extend or retract the metal shaft to a desired length in order to access a fastener positioned in a hard to reach area.

An indexable wrench includes a first member, a second member and a pivotal member. The first member has a first pivotal lug. The second member has a second pivotal lug and a third pivotal lug. The second pivotal lug includes a first engaging portion and a limiting groove, and a limiting member is arranged in the limiting groove. The pivotal member is movably inserted through the first pivotal lug, the second pivotal lug and the third pivotal lug to movable between a locked position and an unlocked position. The pivotal member includes a second engaging portion engageable with the first engaging portion, a first positioning groove and a second positioning groove engageable with the limiting member.
