20100064860 | Extension shaft for holding a tool for rotary driven motion - An extension shaft for holding a tool for rotary motion of the tool includes a first end adapted to cooperate with a chuck of a handheld instrument and a second end including a tool holder for holding the tool for rotary driven motion thereof. The tool holder includes a base portion operatively connected to the extension shaft and a swivel portion capable of holding the tool. The swivel portion is pivotly coupled to the base portion through a pivot assembly, wherein the tool is capable of being rotated about an angle with respect to an axis of the chuck through rotation of the extension shaft in response to rotation of the chuck. | 03-18-2010 |
20100294089 | UNIVERSAL TOOL EXTENSION ROD - The present invention provides a universal tool extension rod, including a plurality of universal coupling sleeves and first and second end joints. A corresponding polygonal sphere and polygonal driver are mated between universal coupling sleeves, and the polygonal sphere can slide within the polygonal driver in straight mating or universally flexible states. The first and second end joints can be linked with the universal coupling sleeves similarly, so that the tool extension rod can be combined into a straight state or unhinged into a universally bending state where necessary. Both operating states can realize universality, robustness and durability due to multi-angle ability, high torsion and extensibility. | 11-25-2010 |
20110314974 | AUXILIARY TOOL FOR ASSEMBLING AND DISASSEMBLING SPARK PLUG - An auxiliary tool for assembling and disassembling a spark plug is used to assist the assembling and disassembling operation of the spark plug of a vehicle. The auxiliary tool comprises a spark plug sleeve, a flexible extender, and a rotating end portion. The spark plug sleeve is used to cover and rotate the spark plug. The flexible extender has flexibility and one end thereof is fixed on the spark plug sleeve. The rotating end portion is disposed on the other end of the flexible extender and detachably connected with a handle. In operation, the spark plug is firstly loosened by a conventional wrench, and the auxiliary tool then rotates the spark plug. The auxiliary tool is not limited by the limited engine space, so that the operational convenience of rotation operation can be increased and the operational time of assembling and disassembling the spark plug can be shortened. | 12-29-2011 |
20120125164 | Extension Shaft For Hold a Tool for Rotary Driven Motion - A tool having a flexible extension shaft, a first end and, a second end and capable of being bent about its axis. The tool transfers rotary motion from a device to an implement. Both of the ends may be capable of independently being bent about the axis. The shaft may include a male member and a female member for a kit. Further, one end of the tool may include a rotatable member having a first and second implement. | 05-24-2012 |
20120132038 | Flexible Driver - A flexible driver for use within a lumen or other winding cavity. This driver is flexible, versatile, and user customizable. It may consist of a plurality of links and tips depending on the user's needs and the cavity in which it is to be used. It is designed to reduce the amount of unintended and uncontrolled movement between individual link thus eliminating accidental disengagement during use and unintentional rotational movement within the system. | 05-31-2012 |
20140069240 | Flexible Transmission Device for Tool Extensions and the Like - Flexible transmission devices, for example for use a tool extensions for effecting rotation of fasteners that are difficult or impossible to access straight on using the normal output of a tool. A series of internal couplers are connected together end-to-end by constrained ball and socket joints that allow tilting between the axes of the couplers while constraining relative rotation of the couplers about said axes. The internal couplers form a flexible shaft inside an outer casing formed by a series of collar-shaped links joined in adjacent pairs by a single-axis pivot connection, each positioned to coincide with a respective one of the ball and socket joints. | 03-13-2014 |
20140202289 | FLEXIBLE TOOL ROD DEVICE - A flexible tool rod device includes an inner rod unit and a sleeve pipe unit. The inner rod unit includes a drive head, a tool head opposite to the drive head, and a flexible connecting member interconnecting the drive and tool heads. The sleeve pipe unit is made of rigid material and includes a first sleeve pipe and a second sleeve pipe. The first sleeve pipe has a first end portion connected fixedly to one of the drive and tool heads. The second sleeve pipe is telescopically connected to the first sleeve pipe, and is movable relative to the first sleeve pipe between a covered position for providing rigidity to the flexible tool rod device, and an uncovered position to allow resilient deformation of the connecting member. | 07-24-2014 |
20140283657 | Extension Shaft For Holding a Tool for Rotary Driven Motion - A tool having a flexible extension shaft, a first end and, a second end and capable of being bent about its axis. The tool transfers rotary motion from a device to an implement. Both of the ends may be capable of independently being bent about the axis. The shaft may include a male member and a female member for a kit. Further, one end of the tool may include a rotatable member having a first and second implement. | 09-25-2014 |
