    摘要: A hand tool has an elongated shank with a handle at one end and a bit holder at the other end, the bit holder including a cylindrical body having a distal end surface and an axis, the body having an axial bore formed in the end surface of non-circular transverse cross section and terminating at an inner end surface. A neodymium permanent magnet is freely received in the bore and retained against the inner end surface by a thin circular retainer, formed of metal or plastic, which is interference-fitted in the bore. Both flat, disk-like and concave, bowl-shaped retainers are disclosed. A shock-absorbing cushion may be disposed between the magnet and the inner end surface of the bore. A bit formed of magnetizable material is mateably received in a socket portion of the bore and retained in place by the magnet. The portion of the bore receiving the magnet may have a different cross section from the socket portion. The magnet may be disposed in an encapsulation which interference fits in the bore.

    摘要: A socket drive tool has an elongated shaft defining a coupling body at one end thereof with a square drive lug having a detent ball disposed in a recess therein and projecting from a face thereof. A link pin reciprocates in the body and has a cam surface at one end thereof engageable with the ball, the pin being spring biased to a condition holding the ball in a retaining position projecting from the recess, and movable against the spring bias to a releasing condition permitting the ball to retract into the recess. An opening in the body is generally oblong in transverse cross section and tapers from a wide outer end to a narrow inner end, and then tapers back out again a short distance from the narrow inner end. The link pin has formed diametrically therethrough a reverse tapered aperture which tapers from a narrow end near the wide end of the opening to an oblong wide end near the inner end of the opening. An actuator pin extends into the opening and through the aperture, being seated in the inner end of the opening, the outer end of the actuator pin projecting from the opening for manual access by a user to pivot the pin and thereby reciprocate the link pin. An outer lip portion of the opening has a width slightly less than an enlarged annular flange portion of the actuator pin to retain the pin in the housing.

    摘要: The open-end wrenching head includes two jaws and a throat interconnecting the jaws. The jaws include planar jaw driving surfaces each with a roughened region thereon adjacent to the throat and an unroughened region adjacent to the outermost end of the jaw driving surface, each of the roughened and unroughened regions being constructed and arranged to engage a portion of a selected side of a fastener. The throat may include either an arcuate surface or two planar throat driving surfaces. Each of the roughened regions has a coefficient of friction substantially greater than that of the unroughened regions and may be formed by deposition of an abrasive material by any of a number of processes or by deformation of the jaw driving surface by any of a number of processes.

    摘要: A speed wrench has a short jaw and a long jaw interconnected by a throat, the jaws respectively having short and long driving surfaces which are generally parallel but which may be very slightly inclined with respect to each other. The throat has a generally flat surface portion adjacent to the short driving surface and inclined at an angle of at least 120.degree. thereto and connected thereto by an arcuate recess in the short jaw. This generally flat surface portion may be slightly convex having a radius greater than twice the distance between the driving surfaces. The remainder of the throat is arcuate and is shaped and dimensioned so that it will not contact a fastener engaged with the driving surfaces. Open-end wrench and adjustable wrench versions are disclosed, and in the former the support surface portion of the throat has a length approximately one-half the side dimension of an associated fastener. In the adjustable wrench version, at least the long driving surface may be serrated.

    摘要: The mechanism, used in a ratchet wrench, includes a body carrying an integral stud. A bore extends axially into both and a formed-spring actuator is reciprocally mounted therein. A transverse bore in the stud slidably holds a pin which is connected to the actuator. A socket is applied to the mechanism by pushing the socket against a camming surface on the pin to enable the socket to be snapped onto the pin without operating the actuator. The socket is removed by depressing the actuator. A ramp-like structure in the bore engages an offset part of the formed-spring actuator causing it to divert and move the pin to its release position. An elastomer push button is preferably attached to the actuator to sealingly protect the mechanism and also to provide a nice appearance.
