  • the stop 25 is guided in the locking receptacle 54.2 and the spring arm 54.3 snaps back to its original position.
  • the securing device 50 is fixed to the machining tool 20. If, therefore, the securing device 50 is pivoted, the blocking piece 51 of course also rotates with it. The blocking piece 51 then closes, in the final assembly position shown in FIGS. 28 and 29, the laterally opened bearing receptacle 26.
  • the bearing 12 is fixed in the bearing receptacle 26.

Abstract

L'invention concerne un outil (20) servant au broyage du bois, de la pierre ou d'une matière biologique ou minérale analogue, qui comprend une partie de base (21) et une partie de maintien (27) reliée à celle-ci de manière directe ou indirecte, qui comporte ou soutient un élément de coupe (32), la partie de base (21) étant pourvue d'un logement d'élément d'appui (26) permettant de réaliser un montage pivotant avec un élément d'appui (12) d'une machine de travail. Selon l'invention, un tel outil peut être fixé à un rotor d'une machine de travail de manière fiable sans grande complexité, grâce au fait que le logement d'élément d'appui (26) est ouvert latéralement dans la direction radiale, de manière à former un accès pour l'élément d'appui (12), et le côté ouvert peut être fermé au moins à certains endroits au moyen d'un dispositif d'arrêt (50).
