Portable electronic device having biaxial hinge structure

A portable electronic device, comprising:

• a first body;
• a second body;
• a stand, has a first pivot part and a second pivot part opposite to the first pivot part, wherein the first pivot part is pivotally connected to the first body, and the second body is pivotally connected to the second pivot part;
• and
• a hinge structure, comprising:
• a first bracket, secured to the second body;
• a second bracket, secured to the second pivot part of the stand;
• a first movable base;
• a first shaft, secured to the first bracket and pivoted to the first movable base;
• a second movable base;
• a second shaft, secured to the first movable base and pivoted to the second movable base;
• and
• a sliding shaft, fixed to the second movable base and slidably connected to the second bracket, wherein the first bracket is rotatable about two parallel axes relative to the second bracket and the two parallel axes respectively passes through the first shaft and the second shaft, wherein the second movable base is unable to rotate with respect to the sliding shaft.
