A screwdriver structure includes a main body, a switch assembled with the main body, and a press set assembled with the main body and the switch set. The main body is provided with a drive portion, a first chamber, a second chamber, a resting edge, and at least one first slide. The switch set includes two first clamping portions. When the switch set is pressed, the two first clamping portions are moved toward each other or moved away from each other. The press set is pressed and moved in the first chamber to push the switch set, so that the two first clamping portions are moved to clamp and lock the press set. When the press set is pressed again, the two first clamping portions are moved to release the press set.

A ratchet wrench includes a first room, a second room, an engaging portion, a third room and a first groove in the function end thereof. Multiple ratchet wheels are received in the third room and one of which is rotatably received in the first room. Each ratchet wheel includes a first pivotal portion, a second pivotal portion and a first toothed portion which is defined in a curved and concaved manner in the outer periphery of the ratchet wheel. A pawl is located in the second room and has a second toothed portion which is engaged with the first toothed portion of the ratchet wheel. The distance defined between the deepest point of the first toothed portion to the first pivotal portion or the second pivotal portion is larger than the distance that the ratchet wheel shifts relative to the pawl within the first room.

A driver with two operating positions has a handle with a first shell and a second shell connected that can open with respect to each other. Attached to one of the handle portions is a working end that is configured to rotate substantially, generally ninety degrees between a first position with a working end extending along an axis that is longitudinal with the handle and a second position with the working end extending along an axis that is transverse to the handle.

A buckle, such as for a strap or belt, houses a compact multi tool that is removable from the buckle. The arrangement includes a retention mechanism so the removable multi tool stays secure even with excessive body motion. The buckle can be any type of buckle for a belt or other type of strap. The buckle can couple a belt or strap to itself to create a loop or can couple strap portions to one another. The buckle functionality can be provided by any suitable arrangement, such as a cam lock mechanism, a pin or post-in-hole arrangement or a snap-fit arrangement, for example and without limitation. The multi-tool can include one or more articulating (e.g., foldable) tool elements. In some configurations, the multi-tool comprises a sleeve that receives a body of the multi-tool. The sleeve can include tool features.

A hand tool includes a handle having a room defined therein. A first and second lugs extend from the front end of the handle. A space is defined between the first and second lugs and communicates with the room. A working part is to be connected with a bit, and has a pivotal portion which is pivotably connected between the two lugs. A plate is connected to at least one of the first and second lugs, and has multiple first recesses and a second recesses. A positioning member is located between the pivotal portion and the plate so as to be engaged with one of the first and second recesses to position an angular position of working part. The working part is able to be pivoted and received in the room in the handle.

Embodiments of a screwdriver having a first mode as a full sized screwdriver and a second mode different than the first mode are provided so that the functional use of a standard multi-bit screwdriver is enhanced. In a first embodiment, a screwdriver has a second mode as a precision screwdriver. In a second embodiment, a screwdriver has a second mode as a stubby screwdriver. In a third embodiment, a screwdriver has a second mode for use with a power tool

A screwdriver, comprising a handle having an integral planar pivotal moving and fixed frame incorporating as required a robust wire cutting or stripping mechanism etc. The rigidity of the frames enhanced by their robust attachment within corresponding main and moving plastic over mouldings constituting the handle bodies, the main frame attached to the screwdriver shank. When closed, the handle profiles form the suitably ergonomic profile of a screwdriver handle. A storage chamber for example for interchangeable screwdriver bits can be formed within the handle interior. The wire stripping feature incorporates a method of setting the required length of insulation to be removed from the worked wire comprising of a setting wheel capable of rotational movement around an axle, retained within the main body handle parallel to the wire stripping profile. The setting wheel face incorporating differing depth faces from the wire stripping profiles.

A pair of screwdrivers each having a handle, a nondetachable outer shaft, a detachable inner shaft, and at least two detachable double-ended screwdriver bits. Each screwdriver handle is formed having a hollow space configured to substantially house the outer screwdriver shaft, the inner screwdriver shaft, and the at least two double-ended screwdriver bits of the other screwdriver, whereby, the pair of screwdrivers may be assembled together when not in use so that the outer shaft, the inner shaft, and the at least two double-ended screwdriver bits of both screwdrivers are substantially non-exposed to prevent the potential for accidental user injury.

A component for a bit driving tool is taught having a mid-chamber telescopically received in an outer chamber, a bit storage chamber formed in the mid-chamber and surrounding and rotatable about a central bore, a central rod axially movable through the central bore when the mid-chamber is telescopically retracted into the outer chamber and a flexible arm comprising a magnetic end, movable into and out of axial alignment with the central bore. Telescopic extension of the mid-chamber out of the outer chamber positions the magnetic end of the flexible arm to magnetically connect with a rear end of a bit stored in the bit storage chamber and telescopic retraction of the component moves the flexible arm and the magnetically connected bit radially into the central bore and wherein further telescope retraction of the component pushes the bit axially through and out of the component. A locking tip for use with a bit driving unit is also taught.

A modular tool with improved tool interface structures may feature an adjustable wrench body (110) with tool modules (120) which fit within the jaws (114, 116) of the head of the tool. The tool body (110) (120) that serve as tools or as attachment for tool components, like tool bits or sockets. The tool features a ratcheting engagement of the jaws (162, 172) with a quick release (117) and spring bias (176) that allows for easy attachment of the modules.
