L'invention concerne un porte-mine empêchant la rupture et le coincement des mines, comprenant un tube de guidage de mine (6), un tube de logement de mine (17), et une mine de plomb (1). Le tube de guidage de mine comprend une rainure trapézoïdale semi-ouverte gauche (27) et droite (28) sur sa partie périphérique externe (24), le tube de logement de mine comprend également une rainure trapézoïdale semi-ouverte gauche et droite sur sa partie périphérique externe, la largeur des ouvertures intérieures des rainures trapézoïdales étant inférieure au diamètre de la mine de plomb (1). Le porte-mine comporte en outre un mécanisme d'avance de mine, un mécanisme de blocage de mine, et une gomme (11) complémentaire à un capuchon du porte-mine (12). La gomme comporte un tube de chemisage (10) incorporé dans sa partie centrale. Le tube de chemisage comporte un orifice central (34). Le portemine assure l'avance automatique de la mine. La longueur d'avance de mine est réglée entre 0,2 et 0,5 millimètres. La mine bénéficie d'une protection pendant tout le processus de glissement vers le bas. Des caractéristiques de protection contre la cassure et le coincement de la mine lors de l'écriture sont ainsi réalisées.
