The low profile screw base comprises a screw base body and a positioning compression ring. An assembly hole penetrates longitudinally through the screw base body. A U-shaped slot for a connecting rod to pass through is provided on an upper portion of the screw base body. The inner wall of the screw base body on the opposite sides of the U-shaped slot is provided with internal threads. Snapping protrusions are formed on the inner wall of the screw base body on the opposite sides of the U-shaped slot below the internal threads. A lower ball socket matched with the round head of the ball screw is arranged in the assembly hole of the lower portion of the screw base body. The positioning compression ring used for compressing the round head is snap fitted above the lower ball socket and below the snapping protrusions (6).
