Une fois qu'un arbre de liaison (14) du rasoir électrique est inséré dans l'évidement (311), un bras de levier est généré entre le point de contact, qui relie l'arbre de liaison (14) et la surface inférieure de l'évidement (311), et les axes des pivots (23), et lorsque l'arbre de liaison (14) pousse l'unité de coupe (31), l'unité de coupe (31) peut être réinitialisée, sans fournir séparément une plaque de ressort ou un ressort pour pousser le support, ce qui simplifie la structure et facilite l'assemblage, d'où une réduction des coûts.
