Definitions

  • a coil spring 130 surrounds a portion of the body 112 and is disposed between the body 112 and the retraction collar 114.
  • the coil spring 130 abuttingly engages a clip 144 which is received in a groove 145 around a mid-portion of the body 112 and terminates as an integrally formed clip 134 that is disposed in the angular slot 126 and is designed to releasably engage a recess 38 in a hex or polygonal-shaped bit tip 40 in the same manner as the embodiment illustrated in Figures 3 and 4 .
  • the internal annular sleeve 132 attaches to the rear portion of the retraction collar 114.
  • the floating sleeve 232 can be removed by applying a slight force in a forward direction to overcome the retaining force of the retainer 230 within the elongated annular recess 228. Upon removal of the floating sleeve 232, the reversible bit assembly 210 can be removed from the socket 204 so that the bit drivers 222, 224 can be chosen for use. In another embodiment, similar to the embodiments described above, the floating sleeve 232 can be moved to a parked position in which the retainer 230 engages the socket 204 or a parking groove in the socket 204, rearward of the annular recess 228 to facilitate easier removal of the bits from the sleeve 212.
  • the body 472 also includes an annular groove 502 located at an intermediate location along the body 472.
  • the annular groove 502 is disposed in the exterior surface of the body and is elongated in the axial direction so as to receive a C-shaped hog ring 504 that is received in an annular recess 506 on the interior of the floating sleeve 474.
  • the C-shaped hog ring 504 can travel axially along the length of the annular groove 502 to allow the floating sleeve 474 to float in a forward and rearward direction.
  • the annular groove 502 has forward and rearward shoulders that limit the axial movement of the floating sleeve.
  • the floating sleeve 510 includes an elongated annular recess 512 on an outer surface thereof and a pair of tapered window openings 514 extending through the sleeve 510 opposite one another within the elongated annular recess 512.
  • the window openings 514 each receive a ball 516 therein and a spring band 518 is received within the elongated annular recess 512 over top of the balls 516 to secure the balls 516 within the tapered window openings 514.
  • the balls 516 are designed to be received in a reduced diameter portion 306 of the tool bit 300 between the forward and rearward shoulders 308, 310 to limit the axial movement of the floating sleeve 510 in the forward and rearward directions.
  • first and second shank portions 924, 926 Adjacent the first and second working portions 904, 908 are first and second shank portions 924, 926, each of which is disposed between the respective working portion 904, 908 and reduced diameter portion 912, 914.
  • the shank portions 924, 926 each have a hex-shaped cross-section and are interrupted by an annular groove 928, 930.
  • the first shank portion 924 is configured to be retained in a tool holder of a fastening tool when the second working region 908 is being used to drive a fastener.
  • the second shank portion 926 is configured to be retained in a tool holder of a fastening tool when the first working region 904 is being used to drive a fastener.
  • Disposed between the reduced diameter portions 912, 914 is an intermediate portion 932 also having a hex-shaped cross-section.
  • first and second shank portions 924", 926 Adjacent the first and second working portions 904", 908" are first and second shank portions 924", 926", each of which is disposed between the respective working portion 904", 908" and reduced diameter portion 912", 914".
  • the shank portions 924", 926" each have a hex-shaped cross-section and are interrupted by an annular groove 928", 930".
  • the first shank portion 924" is configured to be retained in a tool holder of a fastening tool when the second working region 908" is being used to drive a fastener.
  • the second shank portion 926" is configured to be retained in a tool holder of a fastening tool when the first working region 904" is being used to drive a fastener.
