The modular tool having a rifle bullet casing as the handle is a tool that is adapted for multiple purposes. The modular tool having a rifle bullet casing as the handle is a kit. The modular tool having a rifle bullet casing as the handle comprises a handle, a connection and an instrument. The handle forms a grip that allows the modular tool having a rifle bullet casing as the handle to be manipulated by hand. The instrument forms the working element of the modular tool having a rifle bullet casing as the handle. The connection removably attaches the instrument to the handle. In the first potential embodiment of the disclosure, the handle comprises the cartridge of a bullet. In the first potential embodiment of the disclosure, the handle comprises the cartridge of a bullet.

A standard ratchet wrench assembly having a handle socket member adapted to removably receive a ratchet drive extension member therein, such that a user can use the ratchet drive extension member to increase the moment force upon said standard ratchet wrench assembly when in use.

The present specification relates to a torque transferring device for power tools, comprising a first portion comprising a first engaging structure arranged at a front end of the first portion and adapted to engage a corresponding mating structure to transfer torque thereto, and a second portion comprising a second engaging structure for connection to the output shaft of a power tool arranged at a rear end portion of the second portion, wherein the second engaging portion comprises an open cavity adapted to receive the output shaft of a power tool. The device further comprising a pin arranged at least partly in the open cavity, wherein the pin is arranged to extend in an axial direction and further arranged to, in use, engage a hole formed in the power tool output shaft.

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.

A high strength drive extension includes a shaft, a sleeve, and a detent. The shaft includes a connecting structure. The sleeve is movably coupled to the shaft. The sleeve includes a driving head. The sleeve defines a hole in which the shaft inserts. The hole defines a receiving region mating with the connecting structure. The detent is configured to releasably retaining a tool on the driving head. The sleeve is disposed between the shaft and the sleeve and is movable between locking and unlocking positions in response to relative movement of the sleeve and the shaft.

Fasteners and instruments with fastener retention mechanisms are disclosed. The fastener retention mechanisms may be independent of fastener deployment forces, such as torque. The fastener retention mechanisms may include spring elements of the instruments, whose flexion is limited by other features of the instruments so that the springs function only in their elastic zones and are prevented from experiencing yielding, plastic deformation, bending, cracking, or breaking.

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.

A wrench extension device having an input and output, operably coupled together to transmit torque there between. The wrench extension device further includes a housing, with a first and second gear disposed therein. The first and second gear are operably coupled to one another with a chain. The wrench extension device further includes a rib disposed between the first and second gear. The rib includes a tapered portion that, along with an interior wall of the housing defines a tapered space. A tapered space defined by the tapered portion of the rib and the interior wall of the housing; wherein said tapered space is wide enough to allow a chain link to pass both horizontally and vertically, and wherein the area of said tapered space is large enough accommodate at least one additional chain links when the chain is slack as opposed to when it is taut.

A tool having a relatively ductile working end for engaging workpieces and a relatively hard non-working portion for driving the tool is disclosed, and a process for making same. The tool is formed with the material in a first state, such as by cold-working, and then only the non-working portion is heat treated to a second state. The working end is thus maintained in the ductile state while the non-working portion is hardened, thus imparting different materials performance characteristics to working end and non-working portion.

A tool connector is provided, including: a shaft, including a connection end configured to be connected to a driving tool; a slidable sleeve, slidably disposed around the shaft; a tubular member, disposed around the shaft, including an inner hole, an insertion opening communicated with the inner hole and a slanted slot communicated with the inner hole, the slanted slot extending inwardly toward the insertion opening; a locking mechanism, including an elastic mechanism and a locking mechanism, the elastic mechanism abutted between the slidable sleeve and the locking mechanism, the elastic mechanism normally urging the locking mechanism in a direction toward the slanted slot, the locking mechanism including a driven portion comovable with the slidable sleeve, and a locking portion received within the slanted slot and radially projectable into the inner hole.
