Abstract

Screwdriver handle has a storage chamber for screwdriver bits, the storage chamber being displaceable from a closed position into an open position by axial displacement of two parts of the handle with respect to one another. One handle part has a core, which is disposed in a cavity in the other handle part. The two handle parts are held in the closed position of the storage chamber by latching means movable out of a latching position by pressure on an actuating zone (8) associated with an end side of the handle.
