Abstract
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. 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, a rear barrel, and a functional tipped device holder having a functional tipped device at its front tip and housed within the casing. A cap is fixedly mounted to the rear end of the rear barrel, 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 into a rotating action of a rotatable rod and secondarily converts the rotating action of the rotatable rod into an axial movement of the functional tipped device holder.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
