1. A tool-holder configured to be fixed to a surface of a workpiece and to carry a tool, said tool-holder comprising:
a first rail and a second rail that are parallel and each of which includes first fixing elements configured to fix one of the first and second rails to the surface; a driving slide including first guiding elements that have a guiding position in which said first guiding elements are configured to provide a sliding connection between the driving slide and the first rail; a drive system configured to move the driving slide along the first rail; a first fixing system; a driven slide including second guiding elements that have a guiding position in which said second guiding elements are configured to provide a sliding connection between the driven slide and the second rail and a second fixing system, an assembly bar a first end of which carries a first complementary fixing system intended to cooperate with the first fixing system to form a removable fixing between them, a second end of which carries a second complementary fixing system intended to cooperate with the second fixing system to form a removable fixing between them, a carriage having a first assembly system, and a movement system on which the carriage is fixed and that is configured to move said carriage along the assembly bar, and a support module including second fixing elements for fixing the tool and a second assembly system intended to cooperate with the first assembly system to form a removable fixing between them, wherein each of the first and second guiding elements includes at least three grooved wheels, at least two of which are disposed along a first longitudinal edge of the first rail, respectively second rail, and at least one of which is disposed along a second longitudinal edge of the first rail, respectively second rail, wherein for each of the first or second guiding elements, at least one group from said at least two grooved wheels or said at least one grooved wheel is movable from the guiding position to a releasing position in which said at least one group is at a distance from the rail, and wherein the corresponding slide includes an actuating system configured to move said at least one group from the guiding position to the releasing position and vice versa, wherein for each of the first and second guiding elements, the actuating system includes a handle that can be moved from a locking position to an unlocking position and, for the movable grooved wheels, an offsetting system mobile between a guiding position in which said grooved wheels are in the guiding position and a releasing position in which said grooved wheels are in the releasing position, and a transmission system configured to drive the movement of the offsetting system from the guiding position to the releasing position when the handle is manoeuvred from the locking position to the unlocking position and vice versa, and wherein for one of the first and second guiding elements, the handle takes the form of a trigger, wherein the transmission system includes a cable connecting the trigger to the offsetting system, and wherein the offsetting system includes: an actuator with a rod, an offsetting arm having a first end connected to the cable and on which the actuator is rotatedly mounted and a second end rotatably mounted on the chassis, a first arm rotatably mounted on the chassis and articulated to the rod, a second arm one end of which is mounted on and articulated to the first arm, and a third arm rotatably mounted on the chassis and carrying the grooved wheel, and wherein the other end of the second arm is mounted on and articulated to the third arm.
