[0002] Shoelaces are used to adjust the tightness of shoe uppers and ensure foot comfort. Traditionally, shoelaces have been adjusted by crisscrossing knots, which is cumbersome and prone to becoming too tight, too loose, or coming undone during walking and exercise, causing considerable inconvenience. The BOA (Boot-Off-the-Lace) knob is a type of lacing system, such as the "Roller Device for Lacing Systems" mentioned in Chinese patent document CN103153112A, which allows for quick adjustment of shoe tightness and prevents shoelaces from coming undone.

[0003] The traditional sewing process for a rotary button is roughly as follows: Figure 1 As shown, first, mark the position of the tongue webbing 4a on the shoe tongue 2a. Then, place the tongue webbing 4a at the designated position on the shoe tongue 2a and hold it down. Then, operate the sewing machine to sew the two ends of the tongue webbing 4a to the shoe tongue 2a respectively. Then, use the mold 1a of the rotating buckle to position the rotating buckle 6a on the shoe tongue 2a. Then, sew the tongue trim 5a and the rotating buckle 6a onto the shoe tongue 2a in sequence. That is, the tongue webbing 4a, the tongue trim 5a and the rotating buckle 6a need to be positioned and operated multiple times to be sewn onto the shoe tongue 2a. The processing efficiency is low and the tongue webbing 4a is prone to skewing and deformation, which affects the appearance quality of the product. Utility Model Content
