Abstract

Lápiz portaminas de punta movible mediante cabeza de presióntubo de guía de las minas y graduación del trozo de mina que sobresale de la punta en posición de escritura mediante la cooperación de un dispositivo de captación de las minasque posee un conducto que deja pasar la mina solo con rocecon un dispositivo de sujeción de la mina consistente en una pinza de sujeción que forma el extremo anterior del tubo de guía de las minas y en un anillo de sujeción que coopera con aquellafijo en el cuerpo del lápizde manera que al ceder la presión de la cabezala punta y el tubo de guía de las minas pueden ser retraídas en distinta medida mediante dos muelles independientes el uno del otro y una vez terminada la retracción del tubo de guía de las minasy al seguir la retracción de la puntase fuerza la mina sujeta por la pinza de sujeción por el estrecho conducto de la puntacaracterizado por estar previsto entre el anillo de sujeción (4) y el tubo (2) de guía de las minas un dispositivo automático de bloqueo quedespués de una parcial opresión de la cabeza de presión (10) y de su escape sucesivointerrumpe la retracción del tubo (2) de guía de las minas con la pinza de sujeción (3) abiertade manera que también durante la última parte de la retracción de la punta (8) la mina no está sujeta quedando dentro de la punta detrás de su conducto (9) de salida.Mechanical pencil with movable tip by means of a pressure head lead guide tube and graduation of the piece of lead that protrudes from the tip in the writing position through the cooperation of a device for capturing the leads that has a duct that allows the lead to pass only with rubbing with a lead clamping device consisting of a clamping clamp that forms the front end of the lead guide tube and a clamping ring that cooperates with that fixed to the body of the pencil so that when the pressure of the head releases The tip and the lead tube can be retracted to different degrees by means of two springs independent of each other and once the retraction of the lead tube is finished and as the tip continues to retract, the lead is forced by the clamp clamping by the narrow passage of the tip characterized by being provided between the clamping ring (4) and the guide tube (2) of an automatic device d e lock that after a partial oppression of the pressure head (10) and its successive escape interrupts the retraction of the lead tube (2) with the holding clamp (3) open so that even during the last part of the retraction of the tip (8) the lead is not held, remaining inside the tip behind its outlet duct (9).
