Le moyen d'arrêt (31) est logé dans le corps (11) et placé de façon étanche sur la surface d'étanchéité à l'eau (211) de la base (21) lorsqu'il est en position d'arrêt. Une plaque de guidage (51) à surface lisse est placée sur la circonférence de la surface d'étanchéité à l'eau (211) de la base (21). Cette plaque de guidage (51) se présente sous la forme d'une structure plane présentant un trou en son centre. La plaque de guidage (51) est fixée à la circonférence de la surface d'étanchéité à l'eau (211) de la base (21), la plaque étant dirigée vers le haut. Des pluralités de lignes saillantes (511) lisses s'étendent sur la plaque de guidage (51) du bord extérieur au bord intérieur de la circonférence de celle-ci, une rainure (512) étant formée entre les lignes saillantes (511) adjacentes.
