[0016] The positioning member includes a plurality of transparent positioning plates 8, the surface of the positioning plates 8 is flush with the surface of the operation panel 1, the positioning plates 8 are provided with limiting holes 9 corresponding to the sewing needles on the buttonhole machine 001 and positioning holes 10 cooperating with the ruler 6, the limiting holes 9 on the plurality of positioning plates 8 correspond to each other, the positioning holes 10 on the plurality of positioning plates 8 correspond to each other and are maintained in a straight line, the plurality of positioning plates 8 are evenly arranged at equal intervals along the scale of the ruler 6, the worker sees the scale on the ruler 6 through the positioning holes 10 so as to align the positioning holes 10 with the scale of the ruler 6, the beam lamp 7 is placed in the limiting groove 4 and passes through the plurality of positioning plates 8 in turn, the inner wall of the limiting groove 4 is provided with two corresponding slide grooves 11, the two ends of the positioning plate 8 slide in the two slide grooves 11 respectively, the two ends of the positioning plate 8 are provided with springs 12, the springs 12 at the two ends of the positioning plate 8 respectively contact the inner walls of the two slide grooves 11.

[0017] Working principle: Lay the clothes flat on the operation panel 1, and make the position of the clothes where the buttonhole needs to be placed correspond to the limit groove 4 on the operation panel 1, and press the two ends of the clothes on the operation panel 1 with the magnetic connection between the magnetic strip 13 and the operation panel 1 to prevent the buttonhole position from deviating due to the deviation of the clothes when the buttonhole machine 001 is operating the buttonhole on the clothes, thereby improving the quality of the finished product.

[0018] When processing buttonholes for clothes of different styles and types, the spacing between two adjacent positioning plates 8 among the plurality of positioning plates 8 is adjusted according to the design and production requirements, so that the buttonhole machine 001 can process the buttonhole spacing that meets the production requirements. Specifically, according to the required buttonhole spacing value, the positions of two adjacent positioning plates 8 in the limiting groove 4 are adjusted by sliding the positioning plates 8 in the slide groove 11, and the positioning plates 8 are aligned with the corresponding scales on the ruler 6, so as to adjust the spacing between two adjacent positioning plates 8 among the plurality of positioning plates 8 to maintain consistency accurately, and the beam lamp 7 works according to the required buttonhole spacing value. The plurality of transparent positioning plates 8 are matched to be flush with the surface of the positioning plates 8 and the surface of the operation panel 1. The light of the beam lamp 7 passes through the positioning plates 8 and is flatly laid on the operation panel 1 and covers the positioning plates 8, and a bright spot mark is shown on the clothing. The bright spot mark is the position of the positioning plates 8 on the clothing, which is the position of the buttonhole to be processed, so that the spacing between adjacent buttonhole positions can be determined on the clothing. The operation panel 1 is pushed to move on the guide plate 2 by the cylinder 3, so that the buttonhole position marked by the bright spot on the clothing corresponds to the position of the sewing needle on the buttonhole machine 001, and the sewing needle on the buttonhole machine 001 is aligned with the position of the buttonhole machine 001. The upper limit hole 9 on the positioning plate 8 corresponds to the buttonhole machine 001, and cooperates with the buttonhole machine 001 to perform buttonhole operation on the clothes laid flat on the operation panel 1, so that the buttonhole spacing processed by the buttonhole machine 001 on the clothes is accurately maintained consistent, and the spring 12 is compressed and abutted against the inner wall of the slide groove 11 to fix the positioning plate 8 in this position, to prevent the positioning plate 8 from shifting when the buttonhole machine 001 processes the clothes on the operation panel 1, causing the position of the buttonhole on the clothes to shift, resulting in a deviation in the spacing between two adjacent buttonholes, thereby reducing the quality of the finished clothes. The worker can see the scale on the ruler 6 through the positioning hole 10 to align the positioning hole 10 with the scale of the ruler 6, further ensuring that the spacing between two adjacent positioning plates 8 is accurately maintained consistent, so that the buttonhole spacing processed by the buttonhole machine 001 on the clothes is more accurately maintained consistent, and at the same time, the limiting holes 9 on the positioning plates 8 correspond to each other and the positioning holes 10 on the positioning plates 8 are kept in a straight line, so that the buttonhole positions on the clothes are kept aligned in a straight line, thereby improving the quality of the finished clothes, enhancing practicality, avoiding economic losses caused by unqualified products and the need for subsequent rework to reduce production efficiency.

[0019] A winding roller 14 that cooperates with the clothes and a motor 15 that cooperates with the winding roller 14 are provided in the limiting groove 4. The winding roller 14 is placed at the other end of the operating panel 1 and corresponds to the limiting groove 4. The motor 15 is fixed at the bottom of the operating panel 1, and the shaft of the motor 15 is fixedly connected to one end of the winding roller 14. A bearing 16 corresponding to the winding roller 14 is installed at the bottom of the operating panel 1, and the other end of the winding roller 14 is rotatably connected to the operating panel 1 through the bearing 16.

[0020] When the clothes are too long to fit on the operation panel 1, after the buttonhole operation of the part of the clothes placed on the operation panel 1 is completed, one end of the clothes is mounted on the winding roller 14. At this time, the sewing needle on the buttonhole machine 001 corresponds to the last positioning plate 8 on the operation panel 1, and the motor 15 drives the winding roller 14 to rotate to wind up the part of the clothes on which the buttonhole operation on the operation panel 1 is completed, thereby driving the unprocessed foreign matter at the other end of the operation panel 1 to move to the operation panel 1, and cooperates with the magnetic attraction strip 13 to be magnetically connected with the operation panel 1, so that the clothes can be moved on the operation panel 1 while preventing the foreign matter from shifting. When the clothes move to the last buttonhole position and correspond to the bright spot mark emitted by the penultimate positioning plate 8, the position where the bright spot mark emitted by the last positioning plate 8 is reflected on the clothes is the position of the clothes to be buttoned, and cooperates with the buttonhole machine 001 to perform the buttonhole operation on the remaining unprocessed part of the clothes, thereby completing the buttonhole operation of the whole piece of clothes, thereby making the positioning device convenient for applying to clothes of different styles and types, further enhancing practicality, and avoiding the buttonhole machine 001 being able to process only part of the clothes on the operation panel 1, thereby reducing production efficiency.
