The disclosure relates to a screwdriver attachment for screws, which has a first shaft section with a first longitudinal axis, and a second shaft section with a second longitudinal axis. The second shaft section is coupled to the first shaft section via a linking disk. The first shaft section has a free end with which the screws are turned. The first shaft section and second shaft section are connected to one another by a spring element, which aligns the first shaft section in a starting position in which the first longitudinal axis and the second longitudinal axis are aligned coaxially. Screws can be readily turned with the screwdriver attachment according to the disclosure, even if there is a certain offset between the axes.

A tool connecting rod is provided, including: a main body, a sleeve member and a magnetic mechanism. The main body includes a driving portion and an assembling portion opposite to the driving portion, and the assembling portion has an assembling hole extending in an axial direction. The sleeve member is non-rotatably disposed on the assembling portion and includes at least one sleeving hole configured to be connected with a connecting member. The magnetic mechanism is disposed within the assembling hole and includes a magnetic member penetrating into the sleeve member and an elastic member abutted against and between the main body and the magnetic member. In a circumferential direction of the magnetic member, a first gap is defined between the sleeve member and the magnetic member so that the sleeve member and the magnetic member are movable radially relative to each other.

A socket for use in tightening or loosening a fastener is provided. The socket includes an outer wall defining a first recess at a first end and a second recess at an opposing second end. The first recess is configured to engage a nut or a head of a fastener for rotation. The second recess is configured to receive a drive member of a socket wrench. The outer wall has an outer surface. A plurality of spaced-apart rotational markings is positioned on the outer surface of the outer wall. The plurality of spaced-apart rotational markings is configured to provide a determination of the angle of rotation of the nut or the head of the fastener.

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 fixed-angle ratchet adapter that uses gears to change the rotation angle for a ratchet or impact driver. One variation is meant to be used at right angles and another variation is meant to be used at 45 degree angles with either used on its own with a ratchet or impact driver or used in concert with various universal joints currently on the market to improve functionality.

The tool connector includes a socket having a receiving space and a through hole communicating the receiving space, a sliding member slidably received in the receiving space, a positioning member received in the receiving space, and a hook member. A funnel-shaped opening is formed at an end of the receiving space. The sliding member is connected to the socket with an end via a first elastic member, and the other end is for a tool bit to abut against. The positioning member is selectively inserted into the through hole. An end of the hook member is connected to the sliding member, and the other end has a hook portion for grasp the tool bit. When the positioning member is moved inward and the sliding member is moved toward the funnel-shaped opening, the hook portion is swingable in the funnel-shaped opening to release the tool bit.

A telescopic hand tool has an inner rod and an outer tube slidable relative to the inner rod. The inner rod is formed with at least one rack gear. The outer tube is formed with a positioning hole. A positioning member is provided in the positioning hole. The positioning member has at least one toothed portion. A control sleeve is slidably fitted on the outer tube. The control sleeve selectively presses the positioning member to make the toothed portion engaged with the at least one rack gear, or selectively releases the positioning member to make the inner rod and the outer tube slidable with each other so that the toothed portion is disengaged from the at least one rack gear and selects a desired meshing point with the at least one rack gear in response to the adjustment. Thus, the length of the telescopic hand tool is adjustable in a stepless manner.

A driving shank assembly includes a tube, a drive head, a connector, two quick release nuts, and two fastening caps. The tube has two mounting portions each provided with a mounting recess for mounting the drive head and the connector respectively. The two quick release nuts are locked onto the two mounting portions of the tube respectively. The two fastening caps are locked onto the two quick release nuts respectively. Each of the two fastening caps has interior provided with an inner stepped edge. The drive head is provided with a stepped positioning edge abutting the inner stepped edge of one of the two fastening caps. The connector is provided with a stepped positioning edge abutting the inner stepped edge of the other one of the two fastening caps.

A ratchet wrench system and kit enable users thereof to enhance grip and mechanical advantage in applying torque to either (a) rotate rotary fasteners or (b) prevent rotary fastener rotation. The ratchet wrench system and kit include at least one ratchet wrench assembly and at least one ratchet interface. The ratchet wrench assembly has a ratchet head and a lever arm. The ratchet head has a male side and a female side. The female side includes both deep and shallow sections. Long and short ratchet interface elements both include a male interface end and a female interface end. The male and female interface ends are respectively matable with the female and male sides of the ratchet wrench assembly. The long and short ratchet interfaces are interchangeably matable with the ratchet wrench assembly for enabling a secondary wrench to grip and enhance mechanical advantage via the ratchet wrench assembly.

An adjustable length handle having a first handle member, a tubular shaped second handle member and an adjusting mechanism interconnecting the two handle members to shorten or lengthen the handle length. The second handle member has an interior channel that receives the first handle member. An inner surface of the channel is in opposing relation to an outer surface of the first handle member. The adjusting mechanism comprises a longitudinally disposed length adjusting slot and one or more laterally disposed engaging slots in the inner surface that receive an engaging member which extends outward from the outer surface of the first handle member. When in the length adjusting slot, the engaging member allows linear movement of one handle member relative to the other handle member to adjust the handle length. When in one of the engaging slots, the engaging member prevents such linear movement to fix the handle length.
