Abstract
A hinge for anchoring and folding on a small pintle which has a diameter between 3 and 7.9 mm to form a stepless swiveling and anchoring by increasing the friction resistant force to counter the torque. It includes a maneuvering structure which has a rotary member and an anchor member that form a rotational displacement on a contact surface therebetween that can be swiveled and anchored in a stepless manner and latched on a fixed location for closing. A braking structure is provided that has braking elements and washers to increase the friction resistant forces so that the small pintle has adequate friction resistant forces to anchor a display device after unfolding. The maneuvering structure has anchor elements and retaining troughs of different sizes that cannot be coupled with each other when the display device is unfolded and swiveled to 180 degrees to maintain the original friction resistant forces so that the display device may be anchored at any angle after unfolded.
