Abstract
A screen supporting device includes a shaft, a bracket, and a torsion adjusting structure. The bracket and the torsion adjusting structure are pivotally on the shaft. The torsion adjusting structure has a limited washer and a torsion spring. The shaft passes through the limited washer and the torsion spring, and two ends of the torsion spring are respectively inserted into the bracket and the limited washer. Thus, when the bracket pivots by being forced, the shaft and the limited washer maintains the position thereof to cause that the relative position of the ends of the torsional spring, which respectively inserted into the bracket and the limited washer, is changed to provide the bracket with an additional torsion. Therefore, the instant disclosure provides the supporting device capable of the torsion variable function.
