Une colonne de guidage (11) dépassant vers le haut est agencée à une position centrale de la base (1). Un trou de guidage (12) est formé au centre de la colonne de guidage (11). Le bloc coulissant (6) de noyau de guidage est situé d'un côté du noyau de guidage (3). Une encoche annulaire (31) est formée à une extrémité inférieure du noyau de guidage (3). Une colonne d'insertion (32) dépassant vers le bas est agencée dans une section centrale de l'encoche annulaire (31) et est insérée dans le trou de guidage (12) au niveau de la base (1) pour insérer la colonne de guidage (11) de la base (1) dans l'encoche annulaire (31). Un ressort (7) est emmanché autour des côtés extérieurs de la colonne de guidage (11) et de la colonne d'insertion (32). Des encoches sont formées sur une surface inférieure du noyau de guidage (3) pour former une pluralité de pièces en saillie (33) du noyau de guidage sur la surface d'extrémité inférieure du noyau de guidage (3). Le système comporte une pluralité d'évidements (16) dans lesquels peuvent être insérées les pièces en saillie (33) du noyau de guidage, ou le système comporte une pluralité de trous (16') qui peuvent être traversés par les pièces en saillie (33) du noyau de guidage.
