description The utility model relates to a lower pin for a ring spinning frame. The lower pin comprises a lower pin body which is T-shaped. The top surface of the lower pin is provided with a speed variation dividing line, wherein the part before the dividing line is provided with a front edge plane which is transited by a circular arc and extends forward; the part behind the dividing line is provided with a rear edge plane which extends backward; the end part of the rear edge plane is a blunt blade; the width (T) of the front edge plane is 5-7mm, the height (H1) of the front edge plane is 22-23.5mm, the height (H2) of the rear edge plane is 23-24.5mm, the total height (H) of the lower pin is 26.5-28mm, and the angle (beta) between a bottom plane of the rear edge plane and an inclined plane of the blunt blade is 45 DEG. The lower pin provided by the utility model can scrap and clean a continuously operating lower leather apron, thereby preventing flying cotton from being accumulated between the lower leather apron and a
