A tool with a handle indexably retained to a pin. The pin is coupled to a head of the tool. The pin allows an angle between the head and the handle to be adjusted, thereby allowing the tool to be used in hard to reach places. The pin is coupled to the head to limit axial movement without the need of a threaded fastener. The reduction of axial movement allows for smooth, consistent operation of the tool.

A method of illuminating a target area and driving rotation a driven tool comprises coupling a light attachment assembly to an elongated extension member by placing a portion of the elongated extension member within a hollow portion of a sheath of the light attachment assembly. Activating a light source of the light attachment assembly. Positioning the driven tool within the target area while grasping the light attachment assembly. Driving rotation of both the driven tool and the elongated extension member while grasping the light attachment assembly when the driven tool is positioned within the target are such that the portion of the elongated extension member housed within the hollow portion of the sheath rotates relative to the light assembly.

Disclosed is a high-loading ratchet tool, which has a main body, a braking structure and a working part, wherein the main body forms a first receiving groove, a second receiving groove and a third receiving groove, and the second receiving groove and the third receiving groove are mainly composed of two circular surfaces, and the braking structure is disposed on the main body. The braking structure has a ratchet, and the two ends of the ratchet respectively form a first shaft segment and a second shaft segment. The first shaft segment is disposed in the second receiving groove, and the second shaft segment is disposed in the third receiving groove. According to this, the relative force of the first shaft segment and the second shaft segment and the main body is dispersed, and enhancing the working part restrictions on external torsion.

A ratchet wrench includes a ratchet unit which has a ratchet tube with a reception hole. A collar is connected to one side of the head and has a slit defined radially through the collar. An engaging member has a first end thereof fixed to the collar, and a second end of the engaging member extends through the slit. The second end of the engaging member is partially located within the through hole of the collar and located above the reception hole of the ratchet tube. An operation ring is mounted to the collar and connected the engaging. A C-clip is mounted to the outer periphery of the collar. When the operation ring is rotated, the second end of the engaging member is pushed to move within the through hole of the collar to position a socket located in the reception hole of the ratchet tube.

An assembly of a wrench and a socket. The wrench has a penetrating driving hole, which has a retaining ring mounted therein. The socket, having a front end and a tail end, comprises a socketing portion axially extended between the front end and the tail end thereof for driving a fastening element. The socket comprises a retaining portion formed on the periphery thereof. The retaining portion has a retaining groove arranged at retaining corners radially indented for matching the retaining ring. The retaining groove is positioned between the front end and the tail end. The retaining portion further has a buffer groove formed between the retaining groove and the front end, so as to allow the buffer groove to successively provide a buffer or damping effect with the retaining ring when the retaining groove is decoupled from the retaining ring. Accordingly, the user is allowed to control his/her force more easily and improves the operational safety for the process of pulling out of the socket.

A shifting device includes a sleeve module and a shifting member movably disposed in the sleeve module. The sleeve module has a through hole. The through hole is divided into a first hole region, a buffering region, and a second hole region. The shifting member includes a third operating section and a fourth operating section. The shifting member is movable between a first position and a second position. The fourth operating section of the shifting member is situated in the buffering region when the shifting member assumes the first position, and the second hole region and the third working hole are adapted to turn a fastening member. The third operating section of the shifting member is situated in the buffering region when the shifting member assumes the second position, and the first hole region and the fourth working hole are adapted to turn the fastening member.

A tool adapter to aid in the removal of a threaded fastener from an article using a drive insert, the tool adapter comprising: (i) a housing comprising a plurality of faces interconnected along one or more respective edges of the plurality of faces to form the housing; and (ii) one or more holes recessed into one or more of the plurality of faces, the one or more holes adapted to receive one or more tools, wherein a first mating end of the drive insert is received into one of the one or more holes of the tool adapter and a second mating end of the drive insert is connected to the threaded fastener; and wherein one or more tools are inserted into at least one of the remaining holes to provide sufficient torque to remove the fastener from the article.

A ratchet wrench set including a ratchet wrench, an extension and sockets. The extension is employed both as a driver extension and a handle extension. The extension is used by a workman to assist in accessing a hard to reach fastener simply by manually coupling the extension to the ratchet wrench driver member at one end and to a socket to the other end of the extension. Alternatively, a workman can couple the extension to the ratchet wrench handle to extend its longitudinal length and thereby improve torque leverage. The extension may have a shaft that is adapted to improve a workman's handgrip so that whenever the extension is longitudinally coupled onto the handle portion of the ratchet wrench it may be more readily gripped.

A length extension assembly for a hand tool comprises at least two elongated extension tubings each having a longitudinal passageway and being of a size and shape that one of the tubings may be selectively inserted into the passageway of the other tubing. The assembly also includes at least two elongated extension bars each of a size and shape that each extension bar may be inserted into an appropriate tubing. The tubings are provided with longitudinally spaced locking holes. Each bar is provided with a locking member which can enter and be engaged in one of the locking holes to connect the bar to its tubing. Optionally, one tubing could be inserted into the larger tubing and a locking member on the smaller tubing could be engaged in a locking hole of the larger tubing to connect the tubings together. Various length selections can be achieved by connecting a bar to at least one tubing or by connecting a bar to one tubing and connecting that tubing to a larger tubing. Additional length adjustment is achieved by the engagement of a locking member in an appropriate locking hole.

A ratchet structure includes a body. The body is provided with a plurality of equally spaced ratchet teeth extending along the axial direction, and an annular groove is formed on the body to divide the body into a head portion and a body portion. The ratchet teeth are located on the body portion, and a predetermined groove is provided between the ratchet teeth and the annular groove. With the predetermined groove, when the milling cutter mills out the groove in the body portion and enters the predetermined groove, the waste chips connected to the annular groove bottom surface of the annular groove will be surely cut off, thereby solving the problem that it is difficult for the ratchet wheel to get rid of the waste chips.
