Abstract
A double-shaft type rotary shaft pivotal positioning structure includes an elastic guide assembly and two pivot shafts. The elastic guide assembly includes two containing portions which are outwardly communicated and formed with two opposite elastic arms and two corresponding planed press-contact sides. The pivot shafts are respectively centrally provided with center section portions that are utilized to respectively enter the containing portions of the elastic guide assembly and each of which includes a periphery provided with two center section planed surfaces capable of being pressingly contacted with the press-contact sides of the elastic guide assembly. When the pivot shafts are synchronously pivoted close to a preset positioning angle, the center section planed surfaces of the pivot shafts are capable of rotatably attaching toward the press-contact sides of the elastic guide assembly, thereby enabling the pivot shafts to approach and be positioned at the preset positioning angle.
