[0002] According to the process requirements, police shirts and other clothing products need to be installed with buttons on one side of the front placket. In order to achieve efficient and automatic buttoning, a button sewing machine is used. The button sewing machine is equipped with a button clamp. When sewing the buttons to the placket of the clothes, the button handle eyes need to be aligned with the button holes on the button clamp. The needle and thread of the button sewing machine pass through the button handle eyes and are bound together with the front door of the clothes. After sewing, it is necessary to manually move the button handle pressure rod, then put in the button and manually release the pressure rod to make the pressure rod press the button handle tightly. This operation is time-consuming and labor-intensive, and has low production efficiency.
