Abstract
Abstract The invention relates to a quick tightening tool carrier having a body intended to be fixed onto a machine tool and a support carrying a cutting tool. Both the body and the support have a flat surface provided with identical notchings and cooperating with one another. A collar made in two parts fixes the support onto the body. Each part of the collar is connected to one side of the support, and both parts surround the body and are connected to each other by means of a hinge comprising an excentric shaft, the angular positions of which determine the tightened or untightened position of the support on the body.
