| (54) | Hand-held multipurpose casing with structure for reversibly extending functional tipped device |
| (57) A hand-held multipurpose casing, with a functional tipped device housed within the
casing so as to be linearly and reversibly extendible relative to the casing, is disclosed.
This casing has a cylinder-type or screw-type actuating unit designed to reversibly
extend the functional tipped device. The screw-type actuating unit has two spiral
screw engagements, with opposite spiral directions. In an embodiment, the hand-held
multipurpose casing has a front barrel, a middle barrel (12), a rear barrel (15),
and a functional tipped device holder having a functional tipped device at its front
tip and housed within the casing. A cap (16) is fixedly mounted to the rear end of
the rear barrel (15), with two holding slots formed on the front end portion of the
external surface of the cap at diametrically opposite positions. A screw-type actuating
unit movably engages with both the functional tipped device holder and the cap through
two spiral screw-type engagements with opposite spiral directions. The above unit
thus primarily converts an axial movement of the cap (16) into a rotating action of
a rotatable rod (110) and secondarily converts the rotating action of the rotatable
rod (110) into an axial movement of the functional tipped device holder. |
