Abstract: An articulated screwdriver has a handle and a shank secured on the handle. The shank has a ball-end formed at a free end thereof, and an outer thread formed on an outer periphery close to the free end. A joint sleeve has a joint formed at a first end thereof and an opening defined at a second end. The ball-end is pivotally mounted in the opening. A positioning sleeve screwed on the shank has an inner thread engaged with the outer thread. Whereby, when the positioning sleeve is moved forwards to enter the opening, the shank is unable to be pivoted about the joint sleeve and when the positioning sleeve is distant from the opening the joint sleeve is able to pivot relative to the shank.

Abstract: A swingable handle is adapted to deliver torque for rotating a tool bit of a hand tool, and includes front and rear handle bodies pivoted to each other. A first mating wall of the front handle body mates with and is turnable relative to a second mating wall of a spring-biased coupling member which is movable longitudinally relative to the rear handle body. A retaining member is disposed between the first and second mating walls to restrain the first mating wall from rotation relative to the second mating wall. The coupling member has a shifted portion with a relatively large actuating wall surface so as to be conveniently actuated to move the second mating wall away from the first mating wall.

Abstract: A tool for manually driving fasteners having a handle, a shank, and a working tip or bit retainer includes a ball joint for allowing angular displacement of the bit retainer relative to the tool's longitudinal axis so that the tool can be directed into difficult-to-reach areas. The tool further includes a rotatable sleeve threadably mounted on the distal end of the shank, a ball joint disposed at the distal end of the shank, and the tool bit retainer secured to the ball joint by a retaining pin and capable of holding one of a variety of bits. Rotation of the sleeve on the shank binds the bit retainer in axial alignment with the shank, and counter-rotation of the sleeve releases the bit retainer for angular displacement or repositioning with respect to the tool's longitudinal axis.

The slide block is controlled by the press block to engage or disengage the toothed slots of the retaining plate, thereby adjusting and locating the application force angle of the grip portion.

Abstract: A ratchet wrench consisting of a socket driver head pivoting or fixed at one end, an elongated handle in the middle, and a pivoting extension shaft having an extended handle grip at the opposite end. The wrench is designed to install and tighten nuts onto machine bolts and break loose and remove nuts from machine bolts wherein the nut is in a recessed or confined area making it hard to reach with a conventional fixed-handle ratchet wrench. The extended handle grip is generally U-shaped with a linear section perpendicular to and substantially centered about the end of the extension shaft. The U-shaped handle of the extension shaft extends the user's reach when applying the torque necessary to install or remove a nut located in a cramped work space. In addition, the U-shaped handle includes a magnet for retrieving articles that are out of the reach of the user.

Abstract: A multipurpose tool having pivoted jaws is provided. Elongated handles are attached to the butt end of each jaw. The handles are channel shaped and define recesses into which the interconnected jaw members can be swung or retracted so as to be nested in the handles. Handle covers are pivoted to each handle and include an opening through which the jaw members pass when moved between the open and closed positions.

Abstract: A multi-purpose hand tool which includes a handle body with a plurality of drive tools mounted on an axis at one end allowing various tools such as hex tools, screwdriver tools, torx tools and others to rotate for use. Pivoting folding wingbars are affixed to the handle by an axis to give additional torque to the drive tools. At the opposite end of the drive tools in the handle is a square opening to receive various independent hand and power ratchet drives. The tool incorporates lifting levers which are affixed to the handle by an axis. The levers when depressed toward the folding tool will lift the drive tools away from the handle to provide easier selection of a particular drive tool. A second embodiment has a ratchet mechanism assembly with two folding wingbars which eliminate the need for an independent ratchet handle or driver.

Abstract: A tool for engaging sockets includes a shank with a handle one end of the shank and a slot defined longitudinally in an outside of the other end of the shank. An engaging member is slidably received in the slot and a spring mounted to the shank urges a first protrusion of the engaging member. A sleeve is movably mounted to the shank and a shoulder portion extends inward from an inside of the sleeve. The first protrusion is urged by the spring and engaged with the shoulder portion. When sliding the sleeve, a second protrusion of the engaging member is controlled to extend from the slot so as to engage with a socket.

Abstract: A wrench assembly includes two arms pivoted at the middle by a connection device. The connection device includes a bolt extending through two cross-bores in the two arms and a stem is biased received in a recess in the bolt. A button connected to the stem and has a rod extending perpendicularly therefrom. The first arm has a hole and the second arm has a concavity which is in alignment with the hole. A block and a spring are received in the concavity. The rod extends through the hole and compresses the block. When the block is located between the first arm and the second arm, the two arms are not pivoted with each other. When the block is pushed into the concavity by pushing the button, the two arms can be pivoted about the bolt.

Abstract: A ratcheting tool includes a head including an end with an arcuate toothed face and a handle having an end defining a compartment for pivotal connection with the end of the head. The handle includes a longitudinal hole having an inner end and an outer end communicated with the compartment. The handle further includes a transverse hole communicated with the inner end of the longitudinal hole. A catch is mounted in the longitudinal hole and includes a first end with an arcuate toothed surface and a second end. A push button is mounted in the transverse hole and includes a stem, the stem including a relatively higher portion and a relatively lower portion. An elastic member biases the push button to a retaining position in which the second end of the catch engages with the relatively higher portion of the stem such that the arcuate toothed surface of the catch is biased to engage with the arcuate toothed face of the head, thereby retaining the head in an angular position relative to the handle.

Abstract: A wrench with interchangeable, pivotal, rotatable tool pieces on at least one end. A snap-on tool piece, preferably a wrench, fits into a pivotal end piece which is pivotably held to an extension arm by a toothed pin in toothed apertures. The extension arm is pivotably attached to a rotating shaft by toothed pins. There may be another pivotable snapon connection for a tool piece at the opposite end of the shaft. As an alternative, the tool piece fits into a pivotable end piece which is positioned at the end of a pivotably segmented shaft which fits inside the casing and handle of the tool. The location of the tool piece in relation to the handle may be easily set and secured. The multiplicity of possible tool pieces and positions makes this tool highly versatile and capable of reaching into hard-to-reach areas. Thus, bolts in car motors may be reached without having to partially dismantle the motor.
