Disclosed is a biaxial hinge mechanism used on a mobile terminal, comprising a first shaft and a second shaft parallel to each other, and a first support and a second support, wherein the first and second supports are respectively connected to the connection ends of the first and second shafts; the first and second supports are provided with connection end faces facing side faces of the connection ends; riveting columns formed in an integrated manner are provided on the connection end faces; connection through holes are provided on the connection ends; and the riveting columns are connected to the connection through holes. The spaces of the side faces of the hinge, rather than the spaces in the thickness direction of the hinge, are fully used to connect the supports, providing a high space utilization rate and aiding in greatly reducing the thickness of the hinge, and the used connection structure facilitates installation of the supports on the side faces of the hinge, providing a high connection strength. A relatively large rotating torque can be realized by the relatively small size, for example, the torque can reach over 3.5 kg·cm with the overall outer diameter within 3.3 mm.
