Abstract

A folding electronic device includes a first case, a second case, and a hinge element. The hinge element includes a shaft, a swing member, a toothed gear, and a spring clip. When the first case opens up at an about 180 degree angle relative to the second case from a folded position, the central projection of a spring clip engages with one tooth of the toothed gear, the first case may rotate relative to the second case under the horizontal direction or the vertical direction from any angle between about 0 and 180 degrees.
