The invention belongs to the technical field of building components and relates to a stretching and drawing buckle. The stretching and drawing buckle solves the technical problem that connection stretching and drawing force in the prior art remains to be improved. The stretching and drawing buckle comprises two connecting nuts, and a connecting rod penetrates the two connecting nuts. The two ends of the connecting rod are each provided with an expanding part with the outer diameter larger than that of the connecting rod. Each connecting nut comprises a connecting end and a stretching and drawing end which are connected with each other. Internal threads are arranged on the inner wall of each connecting end. A through hole for the connecting rod to pass is formed in the inner wall of each stretching and drawing end. The hole diameter of the inner wall of each stretching and drawing end is smaller than that of the inner wall of the corresponding connecting end, and therefore the joints of the inner walls of the stretching and drawing ends and the connecting ends form clamping bosses capable of clamping the expanding parts on the connecting rod, and the outer surface of each clamping boss is formed by connecting at least two supporting faces which are not located on the same plane. The stretching and drawing buckle has high strength and higher stretching and drawing force, and connection is more reliable.
