A multi-functional energy saving power transmission mechanism has a plurality of miniature motors assembled together into a motor assembly, a down-speed gear set and an output gear set. More than one down-speed gear set can be arranged in sequence for further reducing the speed of the motor assembly and generate a larger torque output. Each down-speed gear set has a gear mounting block with a main central driving shaft. One end of the shaft has a spur gear or an annular gear and the other end has a spur gear. The gear mounting block also has a plurality of gear mounting holes disposed around the central driving shaft. A plurality of minor driving shafts can be selectively engaged with the gear mounting holes so as to make the driving connection between the down-speed gear sets or to the output gear set in a smoother manner. The motor assembly mounting block and the gear mounting blocks of the down-speed and the output gear sets can be integrally molded together in advance in any number or in different shapes by injection molding. Any number of motor assemblies each having a plurality of miniature motors can be coupled together by a coupling member having a couping joint at one end and an annular gear or a spur gear at the other end so as to effectively boost up the power output thereof.
