A single-button support mechanism is provided to improve a turning means joining an upper portion and a body of a device. The support mechanism constructs a pivot and a holding groove at the upper portion and, at the body, a cam trough, a button groove, and another groove for accommodating a retaining member to further hold a first spring. The cam is formed as saw type teeth at a peripheral thereof, and each tooth of the cam has a notch engageable with a position button. By applying the single-button support mechanism, the turning means can utilize the cam moving in the cam trough for engaging with the upper portion at a selected angle, and utilize the position button movable in the button groove for controlling the opening or closing of the upper portion.
