The present invention discloses a cantilever type screen-printing machine with double platforms that possess a gear reducer motor with a hollow shaft to rotate a screw of a threaded screw unit and further drive a threaded rod to move upward and downward without rotation inside the hollow shaft thus make a transverse sliding assembly move vertically and synchronously with the threaded rod. Moreover, by a rectangular frame and two sets of horizontal micro adjustable chase clamping mechanism transversely fixed on the rectangular frame, the relative position between the chase and the print materials is adjusted directly. The upper and the lower platforms are driven and powered by two gear reducer motors and a homocentric coaxial-type driving mechanism respectively. By the simplified driving mechanism, the printing efficiency and productivity are enhanced.
