ABSTRACT:
The device is characterized in that the nose of the tooth-carrier has a general structure in which two end regions thereof, one corresponding to the area of junction of the said nose with the body of the tooth-carrier and the other to the free end of the tooth-carrier, assume in cross-section a dovetail structure, the dovetail at the first end region being inverted compared to the dovetail at the second end region, the cross-section of the end projection of the nose of the tooth-carrier being constant and the upper face of junction of the said projection with the base of the tooth-carrier assuming a curved structure with the convexity directed outwards, the lateral faces of the nose of the tooth-carrier assuming a structure of flat facets, one of them carrying in proximity to the junction with the body of the tooth-carrier a substantially vertical indentation for the coupling of the retaining cotter pin.
