Cord release of window covering

摘要

A cord release for a window covering includes at least two cases engaged together to form a barrel with an opening at a top thereof. The cord release is defined with a frontal plane and a sagittal plane. A left side and a right side are defined at opposite sides of the sagittal plane, and a front side and a back side are defined at opposite sides of the frontal plane. The opening has a first collecting portion at the front side of the frontal plane and the right side of the sagittal plane, and a second collecting portion at the back side of the frontal plane and the left side of the sagittal plane. Therefore, the cords will be led to the first collecting portion and the second collecting portion to disengage the cases by the struggle force.
