Abstract
A driving mechanism for curtain cord winding reels includes a driving module, and first and second transition shafts mounted to two sides of the driving module. The driving module includes a base, a power member assembled in the base, and a middle shaft connected to the power member and mounted to two sides of the base. Two ends of the middle shaft extend out of the sides of the base and form a first shaft hole and a first axis. The first and second transition shafts are mounted to the 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 and second shaft holes, the first and second axes are matched with one another, and are non-circular.
