Abstract

A hand-held device includes a first portion and a second portion. The first portion is engaged at least in part with the second portion while being movable in translation in an axial direction relative to the second portion. The first portion presents a first distal end while the second portion presents a second distal end opposite from the first distal end in the axial direction. A blocking device is configured to prevent the first portion from moving in translation in the axial direction relative to the second portion only when, considered in the gravity direction, the first distal end is arranged above the second distal end. The blocking device includes a chamber and a ball or the equivalent housed in the chamber.
