A multi-shaft pivot shaft device includes an assembled section mounted on the display module, a fixed section disposed on an apparatus body module and a drive unit (or transmission module and linking module) disposed between the assembled section and the fixed section and/or a reaction module disposed between the assembled section and drive unit. The assembled section, fixed section and the drive unit are pivotally connected with a shaft system. When the assembled section moves from an initial position to a set position, the drive unit is displaced (lowered) and/or the assembled section is moved back (to adjust the angle) so as to achieve a complex moving effect. In addition, the display module raises the apparatus body module and the display module is automatically positioned in an angle or a position for a user to easily watch.
