A transmission mechanism including a first shaft and a second shaft extending rotatably through a first positioning plate and a second positioning plate. The second positioning plate is spaced apart from the first positioning plate. A first gear is mounted on the first shaft between the first positioning plate and the second positioning plate, and has a first helical tooth portion. A second gear is mounted on the second shaft between the first positioning plate and the second positioning plate, and has a second helical tooth portion having a same tooth profile and helix angle as the first helical tooth portion. A middle gear is located between the first gear and the second gear and has a transmitting helical tooth portion engaging the first helical tooth portion and the second helical tooth portion. The middle gear rotates about an axis perpendicular with the first shaft and the second shaft.
