Abstract

The invention discloses a projection screen bracket with a stable use state and a using method of the projection screen bracket with the stable use state. A screen accommodating barrel (5) is mounted on a supporting rod (1) through a first adjustment mechanism, and a first locking bolt (8) is unscrewed, so that a sliding block (7) can slide up and down on the supporting rod (1) to adjust the position; a straight rod part (3.2) is mounted at the top end of the supporting rod (1) through a second adjusting mechanism, and a second locking bolt (10) is unscrewed, so that the height of a screen hook (3) can be adjusted; the middle section of a rigid hanging line (11) is set to be a protruding section (15). According to the invention, the accommodating barrel is fixed on the supporting rod through a rotating shaft, and rotates and is vertically placed to accommodate a screen, the accommodating barrel is rotated and placed horizontally and then the screen is pulled out to be put into use, and the screen and the bracket can be overall transported and stored. The middle section of the rigid hanging line is set to be a protruding section, and the screen hook is stably clamped in the protruding section rightly when the screen is hung, so that the screen can be effectively prevented from swinging left and right in the using process.
