1. Apparatus for positioning nuts to be set and for setting blind rivets, comprising: an electroportable body (1) containing an electric motor (2), a mandrel (3), drive means to i) maintain and to pull a head of the rivet and ii) to pull, screw and unscrew a nut to be set, means for pre-adjust
1. Apparatus for positioning nuts to be set and for setting blind rivets, comprising: an electroportable body (1) containing an electric motor (2), a mandrel (3), drive means to i) maintain and to pull a head of the rivet and ii) to pull, screw and unscrew a nut to be set, means for pre-adjusting a path of the mandrel (3, 29, 36) permitting, after a pre-regulated course of the mandrel (3, 29, 36), an automatic return, and an electronic control means to automatically make an adjustment of a path for a rivet whose dimensions have been selected, wherein, the electric motor drives a ball screw (13) connected via levers (5) to a toothed wheel (6) actuating a rack (7) driving a riveting mechanism. 2. Apparatus according to claim 1, characterized by the fact that the adjustment of the path of the mandrel (3, 29, 36) is a distance adjustment. 3. Apparatus according to claim 2, characterized by the fact that the pre-adjustment means are constituted by a cursor (17, 40) which moves a movable detector relative to a fixed detector. 4. Apparatus according to claim 1, characterized by the fact that the pre-selection of the rivet and/or of the nut to be set is carried out by a potentiometer which electrically controls the distance of the path of the mandrel. 5. Apparatus according to claim 1, characterized by the fact that the electric motor (2) is a motor couple. 6. Apparatus according to claim 1, characterized by the fact that the drive means actuating the riveting mechanism are actuated by a hydraulic microcenter, the motor (21) actuates the hydraulic microcenter, and the transmission of energy takes place by means of a hydraulic pump (22) which is an integral part of the hydraulic microcenter. 7. Apparatus according to claim 1, characterized by the fact that the mandrel (3, 29, 36) is adapted to position the nut and an electric motor (41) is disposed along the working axis of the mandrel to screw or unscrew. 8. Apparatus according to claim 7, characterized by the fact that a trigger (42) of the apparatus is the control means, a first pull actuates screwing and a second pull actuates traction over a predetermined course with automatic return and a release of the trigger (42), an automatic unscrewing action for x turns of the motor and stopping the motor. 9. Apparatus according to claim 7, characterized by the fact that a trigger is connected to a distributor (23) connected to a connecting ferrule (24), itself connected to another ferrule (25), which is connected to the hydraulic circuit (26) and (27), which supplies a point A and a point B, on opposite sides of the piston (28), secured to the hollow mandrel (29), O-rings ensuring sealing of the hydraulic assembly, a return spring for the hollow mandrel (29), the end 31 of the hollow mandrel is disposed at the level of the recess (32), which collects items that are pulled, and that the end (33) of the hollow mandrel is located at a level of the nose (34) and of a pulling broach (35). 10. Apparatus according to claim 9, characterized by the fact that the trigger (20) has two functions: first, the trigger (20) closes in the first instance the hydraulic circuit A and B, secondly, the same trigger starts the motor (21), which drives a pump (22), for the preliminarily adjusted path, and that the release of the trigger (20) by opening the hydraulic circuit, gives rise to the return of the piston, of the hollow mandrel, rearwardly. 11. Apparatus according to claim 1, characterized by the fact that the electric motor (2) is positioned substantially along a vertical axis of the electroportable body (1) and is mounted with freedom of pivotal movement relative to the electroportable body (1).
