  • Patent number: 10655683
    Abstract: According to a first aspect of the invention we provide a self-retaining drive shaft assembly for use with a device for tightening and loosening of an industrial fastener having: a drive retainer drive shaft; a drive retainer cap; a drive retainer plunger; and a drive retainer segment assembly. The segment assembly is formed between the drive shaft and the cap. The cap is formed between the segment assembly and the plunger. The segment assembly, the cap and the plunger are formed substantially within the drive shaft. Advantageously the retainer assembly is of unitary construction; requires no loose parts or external implements to engage and secure the drive shaft to a drive head of the device; reduces likelihood of device failure during operation due to improper engagement of the drive shaft; and increases user safety during device operation.

  • Patent number: 9526546
    Abstract: A surgical bone screw 1) and driver (31), and a method for using them for repairing an osteotomy or fracture. The screw has a shaft having a head (5) at its proximal end, screw threads (3) at its distal end and a compression member (7) between the head and the screw threads. In an embodiment, the threads are self-tapping and self-drilling, the head is polygonal, and the sides of the polygon are convex. The driver turns the screw until the threads cross a fracture site and the compression member contacts the proximal bone fragment. The threads and compression member draw the fragments together and leaves the head entirely clear of the bone surface. The screw is removed through a small incision. Tilting the driver to allow the socket to engage an inwardly extending lower portion of the head permits the driver to lift the screw out of the bone.

    Abstract: A universal joint includes a coupling member having an end for coupling with a tool. A body includes a rounded base pivotably mounted to the other end of the coupling member. The body further includes a drive column spaced from the rounded base along an axis. A reinforcing section is intermediate the rounded base and the drive column. The reinforcing section includes an outer periphery having a recessed portion with a receptacle extending in a radial direction perpendicular to the axis. A control member is moveably received in the receptacle to control coupling of the drive column and an object to be driven. In any case, a spacing from an outer end of the control member to the axis in the radial direction is substantially not larger than a spacing from the outer periphery of the reinforcing section to the axis in the radial direction.

  • Patent number: 7726919
    Abstract: A machine tool includes a driver, a tool holder, and a locking device in the form of, for example, an alignment collar. In use, the machine tool carries a tool, such as a surface refinishing bit, which may be lowered into a workpiece bore, such as a cylinder head valve seat, and subsequently rotated by a machine spindle for resurfacing the bore. The machine tool receives a pilot shaft placed in a reference bore associated with the workpiece bore. The pilot shaft functions to ensure general alignment of the machine tool cutting axis and the refinishing surface.

  • Publication number: 20100031784
    Abstract: An extension device for a socket member may include a ratchet member, a first U-joint member connecting the ratchet member and the socket member, a first sleeve member for connecting the ratchet member and the socket member to inhibit the operation of the first U-joint member. The sleeve member may include a threaded connection to the ratchet member, and the U-joint member may include a first ball and socket member. The U-joint member may include a first central shaft member, and the first central shaft member may radially rotate on a first traverse shaft member. The traverse shaft member may be connected to a first pair of arms, and the first arms may be connected to the socket member. The extension device may include a second U-joint member, and the extension device may include a second sleeve member to inhibit the operation of the second U-joint member. The second sleeve member may include a threaded connection, and the second U-joint member may include a second ball and socket member.

  • Patent number: 7597031
    Abstract: A driving tool includes a tool stem having a non-circular spatial engaging member and having one or more flat surfaces, a tool shank having a non-circular socket opening and having one or more curved surfaces for pivotally receiving the spatial engaging member of the tool stem and for allowing the tool shank to be selectively tilted relative to a longitudinal axis of the tool stem. A control ferrule is slidably engaged onto the tool shank and slidable and engageable onto the tool stem for retaining the tool shank in line with the longitudinal axis of the tool stem and for preventing the tool shank from being tilted relative to the tool stem to other angular position.

  • Publication number: 20090173191
    Abstract: A universal joint includes first and second parts interconnected by a coupling element, and a coupling mechanism for detachably engaging tool attachments such as sockets. The disclosed coupling mechanisms include an engaging element and an actuating element. The engaging element can include a pin, and the pin can be oriented either obliquely or longitudinally in the drive stud of the universal joint. The actuating element can include a collar and a central portion that crosses the central longitudinal axis of the drive stud. The central portion can be offset along the longitudinal axis toward the coupling element, and the actuating element can be configured to extend into an aperture formed by the coupling element and the second part of the universal joint.

  • Publication number: 20080168868
    Abstract: An assistant connector for a tool comprises a connecting member, a transmission member and a positioning sleeve. The connecting member is provided with a first engaging sleeve on one end thereof, an engaging section on the other end thereof and a pivot head extending from the engaging section. The pivot head is inserted in one end of a pivot groove of the transmission member provided with a second engaging sleeve on the other end thereof, for forming a freely rotary relationship. In the periphery of the transmission member are formed with a first and a second annular grooves for engaging with a C-shaped ring, respectively. The positioning sleeve formed with a first and a second annular positioning grooves in the inner surface thereof mounts on the transmission member. Thereby, it can meet the requirements of a straight-pole operational mode and a rotary operational mode, achieving simple and convenient operation.
