Abstract
A hinge rotative on two mutual orthogonal axes, it is used in electronic equipment having a screen and a main body; the hinge has a fixing plate having thereon a rotation seat rotative on a vertical axis relatively to the fixing plate and has two connecting legs rotative on a horizontal axis. A nut above the rotation seat is used to screw lock to a rotation shaft, thereby twisting force on the rotation seat can be adjusted; and the connecting legs each has a resilient sleeve forming thereon a plane or forming on its lateral side a strip protruding inwards, by cooperation of the planes/strips with surfaces/recesses on shafts of the connecting legs extending into the resilient sleeves, better positioning effects are obtained; and a connecting area between the rotation shaft and the fixing plate is given with four protrusions, hence the hinge gets a stable structure.
