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.
