Abstract: A single spring supporting device includes a connecting seat, a fixing seat, and a fixing mechanism. The connecting seat and the fixing seat are respectively connected to two sides of the fixing mechanism. The connecting seat is for connecting a display, while the fixing seat is for fixing the supporting device to a position. The fixing mechanism further has a holder, in which a blocking plate and a fixing rod are arranged. One side of the fixing rod is arranged through the blocking plate. An elastic element, in addition, is arranged through the fixing rod, another side of which is rotationally connected to a nut. The display is adjusted to an optimally viewing angle by in cooperation with the blocking plate to control a telescoping operation of the elastic element and by adjusting the relative angles of the fixing mechanism with respect to the connecting seat and the fixing seat.

Abstract: A synchronously adjustable pivot has a function of balancing the torque and is provided between an outer receiving seat and an inner receiving seat. The pivot further includes an outer sleeve. One end of the outer sleeve is provided with a knob and an inner sleeve threadedly connected to the knob. Further, the other end of the outer sleeve is provided with a bolt. Elastic elements are provided at the outside of both ends of the outer sleeve. When the pivot provided with elastic elements is arranged into the inner receiving seat, a washer having high coefficient of friction is disposed between the outer receiving seat and the inner receiving seat. Finally, a bolt is used for fixation. With the above arrangement, when the degree of tightness between the outer receiving seat and the inner receiving seat is enhanced via the pivot, the large friction generated by the washer is used to balance the rotating torque on both ends of the pivot and keep the degree of tightness on both ends thereof equal.
