[0038] Reference Figure 1 and Figure 2 As shown, the utility model discloses a hinge for a folding screen computer, comprising: a shell 1, in which are arranged: a support member 2, a sliding arm 3, wherein: the sliding arm 3 comprises: a first sliding arm 31 and a second sliding arm 32, the first sliding arm 31 and the second sliding arm 32 have the same structure, the first sliding arm 31 and the second sliding arm 32 are both embedded in the support member 2, and can rotate to the same side relative to the support member 2, the first sliding arm 31 and the second sliding arm 32 are both connected to the folding screen, and the folding screen can be switched between the unfolding (0°) and folding (180°) states by rotating the first sliding arm 31 and the second sliding arm 32. In an embodiment, the sliding arm 3 connected to the folding screen is embedded in the support member 2, and the sliding arm 3 is limited by the support member 2 to rotate in only one direction, so that the folding screen is connected by the two sliding arms 3, thereby limiting the folding screen to only one-way buckling and unfolding actions, that is, 0-180° rotation, which can prevent the rotating shaft from over-rotating and causing damage to the folding screen.
