Abstract
Improvements in the mechanisms for retractable tips of pens, characterized by having provided a hollow bushing externally threaded for its coupling to the upper end of the ballpoint pen, in which its lower end has been slotted longitudinally to form leaf springs finished in claws slightly turned inwards and inserted in said bushing, and passing through it, a rod with a wide annular recess and its lower end in a frustoconical shape topped by a rim, scaring said rod inside the bushing.
