Abstract
A device comprises a single motor (30) and a transmission (40) associated with the motor (30) and with a sleeve (22) and which has an input (410) connected to the motor (30) and two outputs (421, 422) which are associated with a movable body (222). One of these outputs (421) is connected to a sliding element (2221) in order to cause it to move translationally, and the other of these outputs (422) is connected to a pivoting element (2222) in order to cause it to be inclined. The two outputs (421, 422) are activated at paired relative speeds in order to ensure the adjustment in terms of depth of the two elements (2221, 2222) of the movable body (222), and of sections (211, 212) of a shaft (21) which these elements carry, and so that only the output (422) connected to the pivoting element (2222) is activated in order to ensure adjustment in terms of inclination of the pivoting element ( 2222) and of the shaft section (211) which it carries. A control is connected to the motor (30) and to the transmission (40) in order to operate them for the translational movement in both opposite directions, permitting adjustment in terms of depth, or for pivoting in both opposite directions, permitt…
