The invention concerns a spring collet whereof the body (1) is divided into a fixed part (6) forming a rigid support and a mobile part (7) forming a flexible element linked to the rigid support by the flexible wall (8). Each part comprises one of the jaws (18, 19). The conical spring washer (2) inserted between the fixed and mobile parts (6, 7) is maintained in place by the flat head screw (3) The stop screw (4) is locked by the lock nut (5). To engage or release the part to be machined, an outer member presses against the surface portion (30) of the table (14) so as to compress the spring washer (2) thereby causing the element (7) to pivot on the wall (8) and spacing apart the jaws (18, 19) from each other. |
