Coupling system between tool holders and machine tools for crushing machines, wherein the tool (1) comprises a cavity (5) with a protrusion (6) having circular profile with radius R and centre C adapted to be concentrically coupled with a suitable semicircular recess (16) having the same radius R′ on the tool holder (2), said coupling being stabilized by at least one safety element (4), such as, for example, a safety pin placed into suitable through holes formed in the tool and in the tool holder and by a tool protrusion (10) penetrating into a tool holder recess (13), said tool holder recess (13) being opposite to said semicircular recess (16). |
