    Abstract: A screwdriver bit is revealed. The screwdriver bit includes a driving portion, a narrow neck portion integrated with and extended from the driving portion, and a working segment integrated with and extended from the narrow neck portion. The narrow neck portion consists of a connection portion, a first tapered transition, and a second tapered transition. The first tapered transition is an arc taper and the second tapered transition is a straight taper. When the screwdriver bit is driven by a power tool and is rotated at high speed, the torsional stress generated is dispersed by the first tapered transition while the second tapered transition is used to reduce torsional stress of the narrow neck portion. Thus the wearing of the screwdriver bit is effectively reduced.

  • Patent number: 8864143
    Abstract: A small outer diameter quick release extension rod is provided with elongated sheet-shaped elastic elements therein for realizing the effect of engaging with a screwdriver head. A second positioning ring in the operating element is used to press against the elastic elements to control them to be engaged in or disengaged from the screwdriver head. The small outer diameter quick release extension rod is easy to operate and has a relatively small outer diameter, not only reducing the structure weight and energy loss, but also enhancing the flexibility of use.
