Biaxial hinge mechanism used on mobile terminal and mobile terminal

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 connection ends of the first and second shafts, the first and second supports are provided with portions for connecting with two relatively rotating components on the mobile terminal;
• wherein the first support is provided with a connection end face facing a side face of the connection end of the first shaft, a first riveting column formed in an integrated manner with the first support is provided on the connection end face of the first support, the connection end of the first shaft is provided with a first connection through hole on the side face of the connection end of the first shaft;
• the first riveting column is connected to the first connection through hole;
• the second support is provided with a connection end face facing a side face of the connection end of the second shaft, a second riveting column formed in an integrated manner with the second support is provided on the connection end face of the second support, the connection end of the second shaft is provided with a second connection through hole on the side face of the connection end of the second shaft, the second riveting column is connected to the second connection through hole;
• and
• the side faces of the connection ends of the first and second shafts are the faces that the connection end faces of the first and second supports face to, respectively, when the biaxial hinge mechanism is in a closed state.
