A draw stud assembly for use with a knockout punch tool having a movable piston, includes a connector attachable to the movable piston, a draw stud, and a quick connect mechanism. The quick connect mechanism includes mating first and second thread segments on the connector and the draw stud, respectively. The connector and the draw stud are movable between a first relative orientation where the mating first and second thread segments are misaligned to permit axial movement between the connector and the draw stud, and a second relative orientation where the mating first and second thread segments are aligned and engaged to inhibit axial movement between the connector and the draw stud. L'invention concerne un ensemble goujon de traction, lequel ensemble est destiné à être utilisé avec un outil de poinçon d'éjection ayant un piston mobile, et lequel comprend un raccord pouvant être fixé au piston mobile, un goujon de traction, et un mécanisme de raccord rapide. Le mécanisme de raccord rapide comprend des premier et second segments de filetage sur le raccord et le goujon de traction, respectivement. Le raccord et le goujon de traction sont mobiles entre une première orientation relative dans laquelle des premier et second segments de filetage d'accouplement sont mal alignés de manière à permettre un mouvement axial entre le raccord et un goujon, et une seconde orientation relative dans laquelle les premier et second segments de filetage d'accouplement sont alignés et en prise pour empêcher un mouvement axial entre le raccord et le goujon de traction.
