Abstract
A screwdriver pen has a forward elongate housing containing four side-by-side screwdriver heads that can slide partially out of the housing selectively for use. A separately formed rear housing slidingly supports four respective manually operable actuators. When an actuator is slid forwards it bears against a respective push wire to move a head into a forward position for use. The housings are joined together using an apertured annular collar and a pin. The pin holds the housings together and prevents relative rotation between the housings.
Claims15
A screwdriver pen comprising a plurality of different screwdriver heads slidingly supported side by side in a forward elongate housing, a separately formed rear housing that is joined end-to-end to the forward housing and contains for each head a manually operable longitudinally relatively slidable actuator for pushing the head forwards so as to be partially exposed for use out of a remote end of the forward housing, in which an aperture in the remote end is formed to engage over and to rotatable grip the screwdriver head so that turning of the forward housing turns the screwdriver head whenever the screwdriver head is partially exposed, and including a push wire for each screwdriver head that extends between the head and the actuator, and releasable catch means for catching each actuator when each actuator is in a forward position, in which the housings are formed of molded plastics material and a reinforcing band is mounted externally of the forward housing surrounding the remote end aperture.
