## Abstract

A supporting device for a rail member includes a first supporting frame, a second supporting frame and a third supporting frame. The first supporting frame has a first longitudinal body. A pair of first transverse parts are arranged on the first longitudinal body. Each of the first transverse parts has a first supporting feature. The second supporting frame is movably attached to the first supporting frame and has a second longitudinal body. A pair of second transverse parts are arranged on the second longitudinal body. Each of the second transverse parts has a second supporting feature. The third supporting frame is movably attached to the second supporting frame and has a third longitudinal body. The third supporting frame is fixedly attached to the rail member, and the first supporting frame and the second supporting frame are both movable relative to the rail member.
