Abstract
The present invention relates to a screen supporter comprising an upper support used for fastening a screen, a base and a support arm. The support arm is pivoted with the upper support through an upper rotation shaft, and pivoted with a torque device on the base through a lower rotation shaft. When the screen and support arm are rotated for lowering the height and folded, the support arm drives a lower core shaft, the lower core shaft drives a cam of the torque device to rotate for changing the position of a contact part which compresses an elastic unit, so a proper supporting torque is generated for working with the downward-pressing torque generated by the screen at different positions thereby fully supporting the screen, and a greater downward-pressing force doesn't required to be applied for lowering the height and folding the screen, thereby saving the required force for operation.
