The invention aims to provide a rotation tool enabling work without obstructing a view of an operator and facilitating fine-adjustment for the tool. A rotation tool includes a flexible shaft including a tool portion at one end and a grip portion at the other end; and a cylindrical exterior body including curved portion on at least a part thereof, wherein a spiral protrusion is formed on at least a part of the shaft and a spiral groove is formed on at least a part of the curved portion, and the shaft is configured to be movable inside the exterior body by screwing the spiral protrusion and the spiral groove to each other.

A torque enhancing device that includes a torque contact body having one or more torque driver and/or recessed recipient torque contact surface configurations, inclusive of those in a multi-tier arrangement. The body having a Z-axis depth or thickness, and each of the torque contact surface configurations includes a pair of X-axis extending torque contact side walls that are spaced apart by L1 along a Y-axis, and a pair of Y-axis extending torque contact side walls that are spaced apart by L2 along the X-axis, with at least one of the one or more torque contact surface configurations having four concave contoured surface portions positioned between respective adjacent most ends of the X-axis extending torque contact side walls and the Y-axis extending torque contact side walls, and a length ratio L2/L1 is less than 1 as to provide a torque enhancement contact surface configuration. A method of driving such as insertion or removal of the recessed recipient such as in fastener form is included.

A magazine baseplate configured to receive a tool and the corresponding tool are described herein. The tool is configured to fit into a tool indention on the bottom side of the magazine baseplate and be secured therein. The tool has a front end and a rear end, each of which has various tools or heads, such as a flathead screwdriver or T10 torx head.

The invention provides a dual-purpose handle, comprising a body, wherein mounting holes are provided in the body and are used for connecting to functional members; the mounting holes are provided in the body in both an axial direction and a radial direction; axial and radial mounting holes provided in the body can enable the handle and the functional members to easily and quickly switch between two connection forms, i.e. straight and T-shaped; and torsional torques that are different in magnitude can be output by means of different connection manners under the action of the same operation force. Clamping devices fitted with the functional members are arranged in the mounting holes; and when the functional members are connected to the handle, the clamping devices can fix the functional members and prevent same from rotating in a cavity of the body of the handle. The axial and radial holes of the handle are configured to be through holes, so that the handle can be adapted to guide needles of different sizes passing through same and is suitable for minimally invasive surgery, thereby further expanding the range of use of the handle.

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 multipurpose drive tool having a handle to secure an extension driver between an extended position and a retracted position. The extension driver has a proximal end with a ¼ inch socket extending outwardly for use with a plurality of driver bits, and a distal end socket having a 5/16 inch socket. The drive tool further has a ⅜ inch and 7/16 inch socket secured to the handle, having a base member housing with biasing springs for frictionally engaging the driver bits. The extension driver has grooves that interact with a ball bearings positional placement thereof, and a pin for securing the extension driver in an extended or retracted position.

A configurable leverage bit driver includes a first elongate shaft having a first bit receiving socket in an end face of the distal end. A second elongate shaft is dimensioned to couple with the first elongate shaft in a first axially aligned bit driving configuration. At least one aperture is defined in a lateral side of the second elongate shaft and is dimensioned to selective couple with the first elongate shaft to configure the first elongate shaft and the second elongate shaft in a second bit driving configuration with the second elongate shaft oriented as a lever arm aligned in a transverse axis to the longitudinal axis of the first elongate shaft. The second bit driving configuration may be one or more of a T-handle or an offset T-handle bit driver for increased leverage in driving a fastener.
