The application includes a fixed base, a first support rod, a second support rod, a cross bar and a retractor. The retractor is moved to the side of the operating table by a universal wheel. The height of the second support rod is adjusted by pressing the locking pin in the telescopic mechanism to adjust the height of the retractor. The cross bar is moved to mesh with the first gear and the second gear in the first rotating mechanism, and the left and right positions of the retractor are adjusted by the force and the lack of force of the second spring.
