发明名称 Retractable combination pen and screwdriver
摘要 A combination tool capable of being clipped into a pocket which incorporates an outwardly biased writing implement, e.g., pen, into a tip of a removable Phillips-head screwdriver tip at one end of a hexagonal tube while having a removable second tip, e.g., regular screwdriver tip at an opposed end. The handle, an inwardly biased clip affixed thereto for fastening into a shirt or pant pocket, is used for facilitating rotational movement of the hexagonal tube with screw tips attached, and is insertable over either tip and at least partially onto the hexagonal tube, an interior hole within the handle being dimensioned so as to permit sliding frictional engagement between the handle and the tube. In a preferred embodiment, the pen has a selectively retractable tip, retracting effected by converting inward radial force into compressive longitudinal movement.
