Driving mechanism for curtain cord winding reels

A driving mechanism for curtain cord winding reels, comprising:

• at least one driving module each comprising a base, a power member assembled in the base, and a middle shaft connected to the power member, wherein the base comprises a first part and a second part, the first part and the second part enclose a hollow chamber for assembling the power member and the middle shaft, wherein first and second ends of the middle shaft are respectively mounted to the first part and the second part, and the second end of the middle shaft extends out of the second part of the base an end surface of the first end defines a first shaft hole, the second end forms a first axis;
• a first end cover and a second end cover, wherein the first end cover is mounted to an outer surface of the first part of the base opposite to the second part, the second cover is mounted to an outer surface of the second part of the base opposite to the first part, wherein the first end cover and the first part of the base enclose a first limit space, the second end cover and the second part of the base enclose a second limit space;
• and
• first and second transition shafts respectively mounted to two sides of the at least one driving module and connected to the cord winding reels, wherein the first and second transition shafts are respectively received in the first and second limit spaces and connected to the first and second ends of the middle shaft, an end of the first transition shaft connected to the middle shaft forms a second axis, an end of the second transition shaft connected to the middle shaft defines a second shaft hole, cross sections of the first shaft hole, the second shaft hole, the first axis, and the second axis are matched with one another, and the cross sections are non-circular.
