Disclosed is a disassembling tool for a secondary battery. The disassembling tool includes a first rotation member configured to be rotatable and to allow a nut to be coupled thereto; a connection shaft coupled to the first rotation member; a second rotation member coupled to the connection shaft to transmit a rotational force to the connection shaft; and a housing, in which the connection shaft is disposed. The housing is inclined with respect to a virtual horizontal line parallel to a ground surface.

A cabinet leg is provided including a body securable to an underside of a cabinet and a shaft engageable with the body such that rotation of the shaft moves the shaft toward or away from the body. A foot is secured to a lower end of the shaft including a first portion attached to the shaft and a second portion rotatable relative to the first portion. A plurality of openings are provided around the periphery of the foot for receiving a first end of a tool such that teeth on the tool engage with teeth on the first portion. Rotation of the tool causes rotation of the first portion relative to the second portion, thereby rotating the shaft and adjusting the height of the cabinet leg.

A driver extension with hand knobs is shown and described. The driver extension with hand knobs includes an elongated rod. The elongated rod has a first end opposite a second end. The first end of the elongated rod is a tool attachment end. The second end of the elongated rod is a securement end for a socket or a screwdriver. A pair of opposing hand knobs are secured along the elongated rod extending away from the elongated rod. The knobs are positioned in the same plane.

A ratchet extender includes a first head having at least one ratchet drive square receiver and a first drive gear, a second head having at least one ratchet drive square and a second drive gear, and a drive shaft coupling the first drive gear to the second drive gear. As a user rotates the first drive gear using a ratchet coupled to the ratchet drive square receiver, the drive shaft rotates, thereby rotating the second drive gear and the ratchet drive square coupled thereto. As a result, a user is able to use ratchets in locations previously unreachable by such tools.

A modular tool bit holder system includes an angle tool bit holder, a flexible shaft tool bit holder. The angle tool bit holder includes a housing containing a first input shaft, a first angle gear rotatably drivable about a first axis, a second angle gear, and a first bit holder rotatably drivable by the first angle gear about a second axis at an angle to the first axis. The flexible shaft tool bit holder includes a second input shaft, a flexible intermediate shaft rotatably drivable by the second input shaft, and a second tool bit holder rotatably drivable by the flexible intermediate shaft. The angle tool bit holder and the flexible shaft tool bit holder are operable separately or in combination. A connection assembly is configured to non-rotatably couple the angle tool bit holder and the flexible shaft tool bit holder when they are operable in combination.

Systems and methods for operating deep brain stimulation are disclosed. In certain embodiments, the systems and methods encompass an adapter a body portion, a shank portion; and a cam system. The cam system is comprised of a camshaft and an eyebolt that secures a latch. The body portion of the adapter is coupled to a hand knob of a microdriver and the shank portion is coupled to a drill. When the drill is activated, the adapter transmits rotational energy from the drill to the hand knob of the microdriver, which automates the raising and lowering of its needle.

A tool kit is provided that includes a tool including a handle and a tool head and a set of tool accessories configured to be coupled to the tool head. The tool accessories each including a drive end that is configured to be coupled to the tool head and a working end opposite the drive end. The tool kit includes a container that is movable between an open position and a closed position. The container includes a first portion including a first retainer that supports the tool, a second portion and a middle portion dividing the first portion from the second portion. The middle portion including a second retainer that supports the tool accessories and the container is selectively stored in a closed position where the middle portion supports the container on a surface in an upright position.

A tool for gaining lateral access to a well includes a head portion configured to advance axially forwardly relative to a lateral access passage. The tool includes a first shaft and a shaft assembly including a second shaft. The second shaft is at least partly received in the first shaft so as to be axially forwardly moveable therewith. In use, axial forward movement of the first and second shafts causes forward advancement of the head portion. The second shaft is axially forwardly moveable relative to the first shaft. The first shaft includes an internal thread and the shaft assembly includes an external thread engaging the internal thread of the first shaft so that relative rotation of the internal and external threads causes the axial forward movement of the second shaft relative to the first shaft without rotation of the second shaft relative to the first shaft.

A length adjustable connection structure contains: an adjustment assembly, an engagement assembly, and a receiving tube. The receiving tube includes an insertion accommodated, a coupling portion, a groove, a trench, and an elongated slot. The engagement assembly includes a fixing portion, a toothed portion, a fitting portion, a hexagonal hole, and a circular hole. The adjustment assembly includes a connector, a locating orifice, a hexagonal column, and a C-retainer. The hexagonal column of the adjustment assembly is received in the hexagonal hole of the engagement assembly so that the engagement assembly is connected on the hexagonal column, the C-retainer is engaged in the notch of the hexagonal column, and the adjustment assembly and the engagement assembly are accommodated in the receiving tube, hence the toothed portion of the fixing portion is engaged in the groove of the coupling portion, and the fitting portion is fixed in the trench.

An instrument for transmitting torque is described. The instrument comprises a torque receiving portion at a proximal end of the instrument, a torque delivering portion at a distal end of the instrument, and a flexible shaft extending between the torque receiving portion and the torque delivering portion. The flexible shaft comprises torque transmitting elements coupled in series along a longitudinal direction of the shaft. A female coupling feature of a torque transmitting element comprises a notch and a male coupling of an adjacent torque transmitting element comprises a protrusion sized to fit into the notch. The notch has a constant width or a narrowing width starting from an outer surface of the torque transmitting element comprising the notch.
