Des plaques d'enclenchement (23, 23) qui sont des éléments de support sont disposées à des endroits en dessous de l'arbre rotatif (60) et entre chacune des parois latérales fixes (2) et deux parois latérales à secousses (3, 3).  Deux trous sont pratiqués dans chacune des plaques d'enclenchement (23) afin qu'elles soient espacées l'une de l'autre d'une distance appropriée, un axe (21) faisant office de premier arbre d'oscillation est introduit et monté dans un des trous et un arbre traversant (22) faisant office de second arbre d'oscillation est monté dans l'autre trou.  L'axe (21) est disposé sur une surface latérale de chaque paroi latérale à secousses (3), la surface latérale faisant face à celle des deux parois latérales fixes (2) qui lui correspond et chacune étant disposée sur un côté de la paroi latérale à secousses (3).  C'est à dire, les quatre axes (21) sont individuellement disposés de façon à correspondre aux quatre plaques d'enclenchement (23).
