Definitions

  • the present invention provides a kind of Bit Holder, which particularly can incorporate with a variety of locking depth of various screws and adjust the extension length of screwdriver freely and use the buckling bead designed on the shank to fix and replace the bit faster and more conveniently; additionally, it can release locking twisting force of bit after the completion of screw's locking.
  • the prior invention includes: a shank 1, on which a combination part 10 that can incorporate with hand tools, was designed; and a C-shaped retaining groove 11 which would be buckled by C-shaped buckle 110, and a reversion locking bulge 12 was designed.
  • a plural locking bead hole 13 was designed for buckling round bead 130, and a combination groove 14, in which a flexible retaining groove 140 which would be buckled by a flexible buckle 141, was designed, and the flexible buckle 141 would be buckled within concaved pentagonal cover 170 of the bit 17 and combine the bit 17 with shank 1;
  • an external sleeve 15 was designed to have a perforation 150 through which the shank 1 and a spring 151 can go; and an internal sleeve 16, whose rear holds one end of the said spring 151, is equipped with a ring concaved groove 160, the ring concaved groove 160 can work with the action of the said buckling round bead 130 and release the twisting force of bit timely (see Figure 2).
  • the said invention cannot work with the locking requirement of various screws, for example, the pan screw's long head remained on the parts results in bad locking.
  • the bit 17 is fixed on the combination groove 14 of shank 1 with the flexible buckle 141 that can fix the bit well but is hard to replace, and generally, a pincers is required for clipping it, which brings inconvenience to the user.
  • the present invention can overcome the prior ones' locking defects and bring convenience to the user so as to meet the important requirement of innovation.
  • the purpose of the present invention is to provide a kind of Bit Holder, which can work with a variety of locking depth of various screws and adjust the extension length of the bit freely; and a buckling bead was designed on the shank for fixing the bit and providing convenient replacement to user; additionally, it can release locking twisting force of bit after the completion of screw's locking timely.
  • the present invention was designed to fix the bit with sleeve to limit and fix the buckling bead located on the combination groove.
  • the Bit Holder means that an outer threading was designed on the sleeve, locking the adjusting sleeve. And a position bead hole was designed for position bead. Adjust the operational state of the long concaved groove of the inner wall of position bead and adjusting sleeve to change the locking position of the adjusting sleeve and the said sleeve. It can change the extension length of the bit and work with a variety of locking depth of various screws and release timely locking twisting force of bit after the completion of screw's locking.
  • the present invention provides a kind of Bit Holder which contains:
  • the sleeve 4 set a perforation 40 designed for the aforesaid shank 2 through, and at the rear of the inner wall of the sleeve was designed an inner ring 41 which can hold another end of spring 211 set on the shank 2, and a gap 410 was designed in the inner ringy cover 41 to work with the operation of locking bulge 22 of the said shank 2.
  • the bit 3 will extend to its maximum. It would be good for the combination of the screw locking the parts deeply, and then turn over the screw with hand tool and take out the screw.
  • a concaved ringy cover 42 was set near the front of the inner wall of the sleeve 4, which can work with the operation of the said buckling round bead 240.
  • the front edge 43 of the sleeve 4 and the front 62 of the sleeve 6 will hold the part 5 (see Figure 8) or change the distance between the sleeve 4 and the sleeve 6 (see Figure 9, 11 and 12) to make the sleeve 4 back.
  • the less thread the bit 3 locks the longer distance between the front edge 43 of sleeve 4 and the one 62 of sleeve 6 is.
  • Inner threading 60 was designed on the adjusting sleeve 6 which can be used for locking the outer threading 45 of the aforesaid sleeve 4; and on the inner wall 61 of the adjusting sleeve 6 with a long concaved glove 610 set in singular or plurality.
  • the present invention contains four parts with the purpose to use this long concaved groove to incorporate with the operation of position bead 440 of the said sleeve 4. While adjusting the locking depth of screw, the extension length of the said bit 3, and, the locking position (see Figure 7 and 12) of the adjusting sleeve 6 and the said sleeve 4 should be adjusted and changed firstly respectively, the extension length of the bit.
  • an auxiliary sleeve 63 was designed at the front of the adjusting sleeve 6 above, as shown in Figure 13-14, as the Embodiment 2 of the present invention, in which C-shaped retaining groove 630 was set on the adjusting sleeve 6, and a C-shaped buckle 631 can cover it; and then screw the auxiliary sleeve 63 into the inner side of the front edge of the aforesaid adjusting sleeve6 (as shown in Figure 16).
  • auxiliary sleeve 63 was designed for the circumstance when the said adjusting sleeve 6 was extended to a certain length beyond its maximum, which can be locked with the adjusting sleeve 6 each other and fixed on the front of adjusting sleeve 6, that would make the user fail to see the correct position of bit and meet the screw with it easily. Therefore adjust and narrow the inside diameter of adjusting sleeve to be close to the one of screw's head with auxiliary sleeve 63, the user will directly know the present position of the bit and meet the screw head with it fast for locking.
  • Embodiment 3 and 4 it is practicable, as shown in Embodiment 3 and 4, to screw the aforesaid auxiliary sleeve 63 into the inner side of the front of the adjusting sleeve 6 while the auxiliary sleeve 63 in the Embodiment 4 into the outer side of the front of the abovementioned sleeve6 for achieving double functions of the auxiliary sleeve designed.
  • the present invention not only can incorporate with the locking of various screws, but also can release the locking torsional force of the bit after the locking according to the required locking depth of adjusting screw; additionally, the present invention can extend the service life of bit. For its small volume, it can incorporate with any hand tool and will not increase the user's burden.
