Patent ID: 7096708

Claim:
A fixing system for fixing a bending tool, said tool having two fixing surfaces for fixing by clamping, and a retaining groove situated beneath one of the fixing surfaces, the groove presenting a top edge and a bottom edge, said system comprising: a clamping body having a first clamping surface suitable for co-operating with one of the fixing surfaces of the tool, a pivotally-mounted tool clamp having a second clamping surface, said clamp being capable of taking up a tool-clamping first position in which said fixing surfaces of the tool are clamped between said first and second clamping surfaces, and a tool mounting and/or dismounting second position in which said second clamping surface of the clamp is spaced apart from said first clamping surface of the body; and a tool-retaining member comprising a plurality of blades, each blade comprising: a first elastically-deformable branch secured in part to the clamp; a second elastically-deformable branch directed upwards and having an end suitable for penetrating into said retaining groove, and a portion suitable for co-operating with the bottom edge of said retaining groove when the tool pivots; and at least one angled portion located between said first and second elastically-deformable branches, wherein when said clamp is brought into said tool-dismounting second position, said end of the second branch remains engaged in said retaining groove; and when said clamp is in the tool-dismounting second position, the assembly constituted by the two branches is suitable for deforming under the effect of the pivoting of the tool so that the end of the second branch becomes disengaged from said retaining groove.
