Patent abstract

A double-axis hinge structure including a fixing member, a first shaft, a first guiding portion, a second shaft, a second guiding portion, and a slide guiding member is provided. The first shaft and the second shaft pass through the fixing member and the slide guiding member. The first guiding portion and the second guiding portion are respectively integrally formed on the first shaft and the second shaft. The slide guiding member has a third guiding portion and a fourth guiding portion. When one or both of the first shaft and the second shaft rotates relative to the fixing member, the guidance between the first guiding portion and the third guiding portion and/or the second guiding portion and the fourth guiding portion drives the slide guiding member to slide, so that the first shaft and the second shaft synchronously rotate in opposite directions by the same amount of rotation.
