ABSTRACT:
A device is described for manual assembly and removal of a working disc in a manual tool for machining surfaces. The tool comprises a hub on which the working disc is screw-fastened and that is rotatably held eccentrically by a support casing made to rotate on its own axis by a driving shaft. The device comprises a pushbutton that can be accessed from the outside and that can slide between an at rest position and a position where it engages one of its ends with a mechanical element integral with said hub to prevent the rotation of the hub while the working disc is screwed or unscrewed.
