ABSTRACT:

FIELD OF INVENTION
This invention relates to screwdrivers and other hand tools which may have replaceable tool-bits.
DESCRIPTION OF PRIOR ART
A large variety of fastening screws of various sizes, with different head types, e.g. slotted, Phillips, and Posidriv, are in use nowadays. These require a corresponding variety of screwdrivers or screwdriver bits. Bits may be selected from a storage unit and transferred to the chuck of a hand tool such as a cordless motorized screwdriver. The user has to remember to return the bits to the storage unit. It is inconvenient to use a succession of different bits at a location remote from the storage unit.
There are a large number of multi-bit screwdrivers on the market. Many of these store the bits loosely in a compartment in the handle, in which the bits may rattle noisily. In order to locate a particular bit it is usually necessary to removal all the bits from the compartment and to sort through them. Other multi-bit screwdrivers have the bits attached releasably to the front of the handle, in which case they are easily dislodged inadvertently.
SUMMARY OF THE INVENTION
The present invention provides a tool-bit magazine for a hand tool, having a body and a sleeve which are relatively rotatable to a position in which an aperture in the sleeve is in register with a recess in the body and thereby permits a tool-bit to be removed from or inserted into that recess.
