The invention discloses a display base wide in application range, and relates to the related technical field of computers. The display base comprises a bottom plate. A base is fixedly connected to the top of the bottom plate. Bottom rods are fixedly connected to the bottom of the inner wall of the base. The tops of the bottom rods are movably connected with a movable plate through groove holes. A lead screw groove is fixedly connected to the top of the movable plate. A rotation rod penetrates one side of the lead screw groove, the end, located outside the lead screw groove, of the rotation rod is fixedly connected with a rotation handle, a clamping groove is formed in the surface of the end, located in the lead screw groove, of the rotation rod, and a clamping device is movably connected in the clamping groove. According to the display base wide in application range, the rotation rod is driven to rotate through rotation of the rotation handle, the rotation rod is used for driving a lead screw to rotate, then the movable rod is driven to move left and right, a vertical plate is driven to move, and fixing of displays different in size is achieved; and through the clamping device, the rotation rod is tightly clamped, loosening is avoided, the fixing effect is good, and universality is high.
