The invention relates to a self-centering part extractor comprising a first spindle (1) and a second spindle (2), said spindles being coaxial to, and independent of one another. A body (3) is screwed to the first spindle (1). The body (3) is secured to the second spindle (2) which supports: a handle (6) that is screwed to the spindle, a lower ring (7) independent of the second spindle (2), and an annular support (8) which is also independent of the second spindle (2) and is secured to the upper handle (6) such that it can rotate freely relative to same. Connecting rods (9) are hinged between the annular support (8) and the legs (4), which rods are connected to the intermediate ring (7) by means of pins (13) and grooves (12). |
