The top buttons are made of steel wire bent by a special process. The collar loops and collar hooks are respectively attached to the left and right sides of the collar. The openings of the collar loops and collar hooks are then hand-sewn on both sides of the collar. When soldiers wear the uniform, the top buttons hook each other to make the collar close tightly, reflecting the military appearance, discipline, neatness and seriousness of soldiers.

[0003] However, after the collar hook is sewn on the right side of the collar, the opening of the collar hook needs to be sewn by hand. Because the collar has a thick lining, manual sewing is time-consuming, laborious, and the stitches are not beautiful or consistent. The labor intensity is high, the daily output is low, and it is difficult to meet the requirements of mass production of military products and process requirements. Utility Model Content
