[0039] It should be noted that since the row of buttons also contains flexible fabrics, during manual operation, the row of buttons is first fixed on the fixing part, and the fixing part is aligned with each button position of the row of buttons so that the row of buttons is stretched and laid flat on the bottom plate 1, wherein the spacing of the fixing parts can be adjusted according to the button position spacing to adapt to different row of button designs, and the fabric to be sewn together with the row of buttons is placed on the row of buttons and aligned with the position to be sewn, and the position to be sewn is opposite to the first positioning slot 4. Since the metal structure of the row of buttons will extend into the fabric of the row of buttons, it is necessary to prevent the sewing needle from touching the metal structure during actual sewing or the operation of the sewing machine, and therefore the sewing needle is aligned through the first positioning slot 4. The first pressing plate 2 is hinged to the bottom plate 1, so it can be turned over on the bottom plate 1 to press the placed buttons to prevent them from moving. The second pressing plate 3 is hinged to the first pressing plate 2. After the first pressing plate 2 presses the buttons, the second pressing plate 3 is folded to press the fabric to be sewn together with the buttons. After the second pressing plate 3 is folded to cover the fabric, the size, shape and position of the second positioning slot 31 and the first positioning slot 4 correspond to each other one by one, so that the needle can pass through the first positioning slot 4 and the second positioning slot 31 during the sewing process to sew the buttons and fabric, thereby improving the accuracy and work efficiency of sewing the buttons and fabric.

[0042] In a preferred embodiment, the first pressing plate 2 and the second pressing plate 3 are both provided with a plurality of magnets 5 for pressing the base plate 1 tightly, and the surface of the base plate 1 is provided with a magnetic attraction portion 11 compatible with the magnet 5, and the magnet 5 and the magnetic attraction portion 11 attract each other due to the magnetic force, thereby achieving pressing and fixing to prevent the cloth from moving or leaving the sewing position, and the magnet 5 and the magnetic attraction portion 11 cooperate with each other to facilitate manual adjustment, which can improve work efficiency and yield rate, and it is easy for technicians in this field to know that, in addition to the cooperation between the magnet 5 and the magnetic attraction portion 11 through magnetic force, other connection and fixing methods are also applicable to fix the first pressing plate 2 and the second pressing plate 3 on the base plate 1. For example, fixing the first pressing plate 2 and the second pressing plate 3 on the base plate 1 by means of buckles and slots can also achieve the purpose of fixing the cloth on the base plate 1.

[0043] In a preferred embodiment, a fixing protrusion 12 for fixing the base plate 1 on a sewing table is provided at the bottom of the base plate 1, so that after manually positioning the buttons and fabrics on the base plate 1, the entire positioning device can be fixed on the sewing machine to directly carry out sewing processing, which plays a role in positioning and fixing and can improve production efficiency.

[0044] In a preferred embodiment, the fixing portion includes a buckle fixing portion 42 for fixing the buckle and a hook fixing portion 43 for fixing the buckle hook, wherein the buckle includes a part with a buckle and a part with a hook, so the fixing portion needs to fix the buckle and the buckle of the buckle respectively, and are respectively set as the buckle fixing portion 42 and the hook fixing portion 43 so as to align and fix the buckle on the base plate 1 to facilitate positioning sewing work.

[0045] The utility model fixes the row of buttons to be sewn beside the first positioning through groove by the fixing part, and then presses the row of buttons by the first pressing plate, and then places the cloth to be sewn on the row of buttons and presses it by the second pressing plate, so that the positions where the row of buttons and the cloth need to be sewn are positioned by the first positioning through groove and the second positioning through groove, which is convenient for the sewing machine to perform sewing processing, and there is no need to manually position the sewing position, thereby improving the accuracy and work efficiency of sewing the row of buttons and the cloth.
