A drill motor racking apparatus for remote operation of a circuit breaker is disclosed. The drill motor racking apparatus comprises: a racking adapter, wherein the racking adapter is adapted to be engaged by and secured in a racking mechanism of a circuit breaker; a gearbox having an input and an output; a flexible shaft cable having a first end and a second end, wherein the racking adapter is connected to the first end of the flexible shaft cable and wherein the gearbox is incorporated between the flexible shaft cable and the racking adapter to provide a torque multiplication required to rack the circuit breaker; and a drill adapter adapted to be engaged by and secured in a drill, wherein the drill adapter is attached to the second end of the flexible shaft cable. A method of using the drill motor racking apparatus is also disclosed.

A telescopic socket includes an outer sleeve, an inner sleeve, and a jointing ring. The outer sleeve includes at least one abutting ball, plural first concave portions, and plural first protruding portions. The inner sleeve is sleeved by and slidably connected to the outer sleeve and includes at least two engaging holes, plural second concave portions, and plural second protruding portions. The second protruding portions are slidably connected to the first concave portions respectively, and the first protruding portions are slidably connected to the second concave portions respectively. The jointing ring is movably connected to the outer sleeve and includes an abutting part and an accommodating part, and the abutting part optionally abuts against the abutting ball. By controlling the jointing ring, the inner sleeve can be slid or positioned relative to the outer sleeve, and the length of the telescopic socket can be changed.

A telescopic device includes a first shaft telescopically coupled to a second shaft. The first shaft defines a hole and an orifice. The second shaft defines a plurality of engaging portions. The second shaft inserts in the hole. The second shaft is movable with respect to the first shaft to a position in which one of the plurality of engaging portions is aligned with the orifice. A positioning device is coupled to the first and the second shafts. The positioning device includes a control being movable and a fastener being movable actuated by the control. The fastener is movable with respect to the control. The fastener inserts and is movable in the orifice. The first shaft is adapted to be unmovably positioned with respect to the second shaft at various positions by the positioning device.

The unique aspect of this invention is the fact that the magnet insert screws into the driver shaft head rather than being pressed in under pressure. The best design for this invention includes self-locking threads as well and the combination of using a threaded installation of the magnet insert and the locking threads is an additional unique attribute to this invention. This unique a threaded install attribute helps prevent the magnet insert from coming out under impact pressure and even if it does it allows it to be reinserted using a screwing mechanism and when reinserted will remain in place unlike existing press-in products. A third unique attribute of this invention is the depression at the top of the magnet insert designed to receive a screwing tools such as a flat head or Philips screw driver, hex, Allen, etc., making it possible to easily reinsert the magnet insert and tighten it firmly in place.

A novel drum speed key tool that provides improved balance and efficiency for the installation, tightening, and removal of drum lug nuts. The drum speed key tool provides a finger receiving cup to allow a user to insert a finger or grip with their hand and efficiently apply rotational force to the drum speed key while maintaining attached to the drum lug nut with reduced slippage of the drum speed key tool from both the user's grip and the drum lug nut.

A hand tool includes a handle, a press member, a shank body and multiple latch assemblies. The handle is formed with a receiving cavity and a locating hole in communication with the receiving cavity. The press member is movably disposed in the locating hole. The shank body is fitted in the receiving cavity and movable relative to the handle. The shank body is formed with multiple sockets. The latch assemblies are respectively mounted in the sockets. When the shank body is moved, (for example, slid or rotated) relative to the handle to make one of the sockets aligned with the locating hole, the latch assembly latches the shank body with the handle. When pressing the press member, the latch assembly unlatches the shank body from the handle, the shank body is movable relative to the handle.

This present invention relates to an extendable wrench and ratchet tool kit comprising a plurality of tool heads, one or more metal shafts or rods, and a metal tube or cylinder including a handle. The extendable wrench and ratchet tool allows an operator to connect any of the metal shafts to the handle at one end and connect any of the tool heads to the shafts at another end. The extendable wrench and ratchet tool kit features a spring-loaded locking mechanism or other similar mechanism to lock the metal shaft or rod at equally spaced grooves in order to selectively extend or retract the metal shaft to a desired length in order to access a fastener positioned in a hard to reach area.

A screwdriver assembly includes a screwdriver shaft and an insert. The screwdriver shaft extends longitudinally from a proximal end to a distal end and having a longitudinal channel extending therethrough. The insert has a longitudinal shaft received within the longitudinal channel and a distal end extending distally relative to the distal end of the screwdriver shaft. The insert shaft is rotatable relative to the screwdriver shaft. The distal end of the insert is sized and shaped to engage a head of a screw. The distal end of the insert is disengaged from the screw head by rotating the insert relative to the screwdriver shaft.

A tool extension rod includes a main piece, a sliding sleeve, and a magnetic assembly. The sliding sleeve is slidably sleeved onto the main piece. When the sliding sleeve moves between a first position and a second position, the magnetic assembly is movable along an axial direction.

A flexible shaft includes a tubular body extending along a central longitudinal axis and having proximal and distal ends opposite one another. The flexible shaft also includes a slot defined by the tubular body and extending along a helical path around and along at least a portion of the body between the proximal and distal ends. The helical path extends around the portion of the body for a plurality of rotations. The slot defines at least two teeth adjacent one another along a direction parallel to the central axis. Each tooth of the two teeth has a feature. In some implementations, a line extending through center points of the features on the two teeth is angularly offset from the central longitudinal axis. In some implementations, a line parallel to the central longitudinal axis intersects a different point on each feature of the two teeth.
