发明名称 Multiple bit unit
摘要 A multiple bit device for an automatic drill or screwdriver includes a plurality of bits of different size and functionality, in one compact unit. The multiple bit unit provides a convenient and handy arrangement of bits which allows the user to easily switch to different bits. Additionally, since all of the bits are in one unit, misplacement is less likely, as is with single bit units. Optionally, at least one extender unit which fits over any one of the bits in the multiple bit unit, and supports an additional bit piece may be included.
