The inner cavity of each roller has a rotatably disposed spherical shaft head of the tripod. The inner wall of each roller track has a guiding groove. The peripheral shape of each roller is cylindrical. The bottom surface of the guiding groove is a plane surface, and two side surfaces of the guiding groove are flat surfaces perpendicular to the plane surface. The peripheral surface of each roller is partially inserted into the corresponding guiding groove, and the peripheral surface of the roller is tangent to the corresponding plane surface.
