Abstract: A torsion adjusting structure, which is installed on a shaft and a carrying member pivoted on the shaft, includes a gear, a pair of friction washers, and a linkage assembly. The shaft passes through the gear and the friction washers respectively abutted on two opposite surfaces of the gear. The linkage assembly installed on the carrying member has an engaging portion. The linkage assembly is adjusted between an engaging position and a separating position. When the linkage assembly is at the engaging position, the engaging portion engages with the gear for enabling rotation of the carrying member to rotate the gear to rub the friction washers, thereby providing the carrying member with an additional torsion. When the linkage assembly is at the separating position, the engaging portion separates from the gear for maintaining the relative position between the gear and the friction washers.

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.
