Abstract
Description
Technical Field

[0002] An existing dual-screen device includes a hinge, two plates and two screens. The hinge is connected between the two plates so that the two plates can be relatively expanded and folded. The two screens are respectively arranged on the two plates, and thus will be correspondingly expanded and folded as the two plates are relatively expanded and folded. When the two plates are relatively expanded to a relative angle of 180 degrees, the two screens are relatively expanded to a relative angle of 180 degrees. At this time, one side of the two screens is quite close, so that the two screens can be used separately and can also be used together to form a larger screen. However, when the two plates begin to be relatively folded and until the relative angle is 0 degrees or a negative angle, the side of the two screens that are close may hit the hinge and be damaged. Therefore, this type of dual-screen device requires a hinge with a push-pull function, when the two plates are relatively expanded, the two plates are pulled close to the hinge so that one side of the two screens are close to each other so that they can be used together as a larger screen, and when the two plates are relatively folded, the two plates are pushed away from the hinge to avoid the side of the two screens that are close to the hinge from hitting the hinge and being damaged.
