Abstract: A screwdriver handle includes first and second handle parts each having an end face with a pivotal coupling portion. The second handle part is pivotable between two positions relative to the first handle part such that the screwdriver handle is switchable between an in-line state and an angled state. Two positioning holes are defined in one of the end faces and a receptacle is defined in the other end face and aligned with one of the positioning holes. A positioning member is mounted in the receptacle and includes an end releasably engaged with one of the positioning holes to retain the second handle part in one of the positions. A control member is mounted on one of the first and second handle parts and operable to disengage the positioning member from the positioning holes to thereby allow the second handle part to pivot relative to the first handle part.

Abstract: A toggle locking tool is provided with an adjustment screw assembly comprising a force-enhancing shank that enables the holding force of the tool to be multiplied manifold. The adjustment screw assembly comprises an adjustment screw conventionally adapted to be fed into and to engage a threaded bore in the outer end of the fixed handle of the tool; however said adjustment screw itself comprises an internal, fine-threaded bore that extends through the length of said screw, and that receives a threaded force-enhancing shank having a head portion adapted for turning manually or with a turning tool. An end portion of said shank extends beyond the adjustment screw to form the bearing surface which, in a conventional toggle locking tool, is provided by the tip of the adjustment screw. Rotation of the adjustment screw provides rapid, low-force locking adjustment of the tool, and subsequent torquing of the force-enhancing shank results in the application of a multiplied locking force to the jaws of the tool.

Abstract: A ratchet driving mechanism includes a main body, an adjusting ring, and a ratchet wheel. The main body includes a grip-connecting member and a rotary seat connected fixedly to the grip-connecting member. The rotary seat is formed with two parallel insertion slots, in each of which two pawls are biased by a spring to move away from each other. The adjusting ring and the ratchet wheel are sleeved rotatably on the rotary seat. When the adjusting ring is disposed in an anchoring position, the pawls engage the ratchet wheel so as to prevent rotation of the ratchet wheel on the rotary seat. When the adjusting ring is disposed in a first-direction position or a second-direction position, two of the pawls engage the ratchet wheel so as to allow for rotation of the ratchet wheel on the rotary seat in only a corresponding direction.

In one preferred embodiment, the activator unit is a pneumatic airbag. The activator unit may have a plurality of chambers. In one preferred embodiment, the actuation arm has a transfer section and an engagement section. The transfer section is for transferring movement from the activator unit to the engagement section. The actuation arm is preferably pivotably attached to the main chassis.

Abstract: A fish tape pliers is formed with opposed planar and curvilinear edges that form or channel disposed distally from the pliers' pivot connection axis. In one operable embodiment, the edges frictionally engage the fish tape within the channel. The fish tape in pulling an electrical wire through a conduit, is directed away from the handles and the users' grip hand. The jaws may have differently contoured or cross-ridged surfaces to provide the desired frictional engagement without damaging the fish tape. The fish tape pliers includes diverse complementary features for crimping, stripping, bending and/or cutting an electrical wire.

Abstract: A tool for holding a rod having a threaded end, such as a bolt, in an aperture is disclosed. The tool comprises a handle with a knife portion extending from the handle. The knife portion has a first thread engaging edge and a second thread engaging edge that form a notch. The first thread engaging edge and the second thread engaging edge are configured and arranged to engage the threads on a bolt or a threaded rod to temporarily prevent it from being extracted from the aperture.

Abstract: The present invention provides rotary positioning structure of the ratchet screwdriver. The rotary positioning structure includes two radial grooves, penetrating radially between the body of the ratchet screwdriver and the central axle hole. There are two -shaped snappers having a transverse rack and two vertical racks, and each is mounted separately into two radial grooves. The two vertical racks are inserted into two vertical slots. The transverse rack is placed opposite to the top flange of gear of the shaft lever. A flexible locker is used to press down the two -shaped snappers. A rotating drum is mounted and limited externally onto the body, while two troughs are arranged at intervals onto an inner wall of the retaining block opposite to the lower rivet holder, thereby forming a rotary positioning structure and offering a higher stability of positioning and ease-of-operation.

Abstract: In a ratchet wrench, a frictional force generation mechanism including a first guide bush and a disc spring is attached to a shank with a locking pin to form a shank assembly. Spring force of the disc spring acts only on the inside of the shank assembly. The shank assembly is inserted from a central space of a first annular hold portion toward a second annular hold portion, and the shank is held by an inner wall of the second annular hold portion. In the back side on which the shank assembly is inserted, the drop-out of the shank assembly from the central space side of the first annular hold portion is prevented by a snap ring attached to a groove of the first annular hold portion. With this arrangement, constant friction is applied to the shank.

Abstract: A locking pliers tool with an improved dual action driver handle comprising two intersecting handles and interacting jaws. When the user grips the handle forward the resultant force produces a locking action. Conversely, when a rearward gripping force is initiated, the tool releases its grip on the object. A limited amount of energy on the inventive handle produces free movement of the handle and gripping mechanism to lock or release. The system operates with a handle and stationary jaw in conjunction with a second pivotally secured jaw and internal adjustment bolt. A second lever handle rests against the adjustment bolt. An over center toggle link connects the second lever handle to the pivotally secured second jaw. A tension spring interconnects the first handle and the pivotally secured second jaw.
