  • Patent number: 6818005
    Abstract: A surgical, tubular-shafted instrument comprises a shaft, an operating rod mounted for displacement in the shaft, a handle part for actuating the operating rod and a connector that detachably connects the handle part to the shaft. The shaft is secured in an axial direction in an inner sleeve of the handle by a locking member that is displaceable radially in the inner sleeve and dips into a recess of the shaft. The radial outward movement of the locking member is limited by a stop element that is displaced into a position releasing the radial outward movement of the locking member. A holding element fixes the stop element in a release position and can be acted upon by the shaft to release the stop element due to displacement of the shaft in the inner sleeve. The holding element is guided for displacement in the handle part outside the inner sleeve.

  • Publication number: 20040144827
    Abstract: A device that advances and holds wire as the wire is fed through the device and prevents any movement in the opposite or reverse direction by instantly locking on the wire when movement in the reverse or opposite direction is attempted includes a main barrel having a bore through which the wire passes and one or more inserts disposed at the feed end of the main barrel for maintaining the longitudinal orientation of the wire as the wire exits the main barrel. Disposed within the bore is a one-way wire locking or clutch assembly that includes a tapered chamber and a plurality of radially arranged locking balls mounted on a circular head of a stem wherein the locking balls allow wire to freely travel therethrough in the feed direction but interact with the tapered chamber to lock on the wire for preventing any movement in the reverse direction.

  • Patent number: 6755423
    Abstract: A tool coupling device includes a stem having a front channel for receiving ends of tool members, and having a lateral orifice communicating with the channel of the stem for receiving a ball. The tool members each has an aperture formed in one end for receiving the ball. A barrel is rotatably engaged onto the stem, and has a peripheral bulge for selectively forcing the ball into the aperture of the tool member. A spring may bias the peripheral bulge of the barrel to engage with the ball, and to force the ball into the aperture of the tool member and to lock the tool member to the stem.

  • Publication number: 20040007437
    Abstract: It is already common in many devices like spanners or pipe wrenches for the pressure between the gripping faces and gripped faces to be related to the torsional load that is applied to turn the gripped object. In these apparatus the grip can be made to relax automatically as the load is removed. The invention relates to improvements in such devices, and to novel designs of mechanical coupling devices that utilise this basic idea. More specifically, the invention firstly proposes a method of improving the performance of an object-gripping tool of the cam-operated gripper-element type, in which method there is applied to the gripper surface a friction-enhancing chemical.

  • Patent number: 6637755
    Abstract: A chuck device includes a socket, a ball, a first ring, an elastic element, a sleeve, a second ring and a spindle. The socket includes a first chamber defined therein. The first chamber includes a number of slots for receiving the corners. The socket includes a hole defined therein in communication with one of the corner-receiving slots. The ball is received in the hole for engagement with the recess defined in one of the corners of the miniature tool bit. The first ring is formed around the socket. The elastic element is mounted on the socket so as to be compressed between the ring and the annular rib, thus biasing the sleeve. The sleeve includes an annular groove defined in and an annular rib formed on an internal surface thereof. The sleeve is mounted on the socket. The second ring is connected with the sleeve for engagement with the first ring, thus retaining the sleeve on the socket. The spindle is connected with the socket.

  • Patent number: 6561523
    Abstract: A tool-bit holder for receiving a tool-bit that automatically captures the tool-bit as it is inserted into the holder with a quick release mechanism to prevent axial withdrawal of the tool-bit from the holder. The tool-bit includes a shank portion with a circumferential groove. The tool-bit holder also includes a hub having a longitudinal bore for receiving the shank and a radial bore partially housing a detent ball used to capture the tool-bit shank at its circumferential groove within the tool-bit holder. A sleeve is axially slidably mounted relative to the hub and has a radial bore in communication with the radial bore of the hub for reception of the detent ball. The sleeve is axially biased by a spring and forces the detent ball against and along an inner ramp face fixed relative to the hub. The inner ramp face forces the detent ball radially inwardly and through the radial bore to seat in the circumferential groove of the tool-bit shank.
