Abstract (en)
[origin: EP0764501A1] The frame has an upper cross-member (10), two side bars and a stop, and incorporates a quick-lock for the cutting tool (3) comprising a thrust bar (50) close to one of the bars or cross-pieces parallel to it, and able to push the tool against the bar or cross-piece. It incorporates springs (80) between the inner face of a bar or cross-piece and the outer surface of the thrust bar to exert a pressure against it, and a retractor. The springs are situated symmetrically on either side of the retractor located in the middle of the bar, and each is fitted into a blind hole (77) in the bar or cross-piece and exerts a pressure against a recess in the rear surface of the thrust bar (50). The retraction mechanism comprises a lug (55) which is fixed to the outer face of the thrust bar (50) and able to slide in a corresponding slot in the crosspiece.
