[0035] In combination Figure 2 And Figure 3As shown, to enhance sewing flexibility, in some embodiments, two first stitching grooves 3 are provided on both the first cover plate 1 and the first base plate 2. One of the first stitching grooves 3 on the first cover plate 1 and the first base plate 2 is evenly spaced and discontinuous, while the other first stitching groove 3 on the first cover plate 1 and the first base plate 2 is evenly continuous. Similarly, two second stitching grooves 7 are provided on both the second cover plate 5 and the second base plate 6. One of the second stitching grooves 7 on the second cover plate 5 and the second base plate 6 is evenly spaced and discontinuous, while the other second stitching groove 7 on the second cover plate 5 and the second base plate 6 is evenly continuous. The evenly spaced and discontinuous first stitching grooves 3 and second stitching grooves 7 can guide intermittent sewing. Suitable for fabric pieces requiring skipped stitches or decorative stitches, ensuring the uniformity and accuracy of each stitch segment; the uniform and continuous first and second thread guides 3 and 7 provide complete straight-line guidance, suitable for large-area continuous sewing tasks, ensuring smooth tracks and tight stitches; therefore, the two different types of thread guides support the sewing tracks of different parts of the upper and lower fabric pieces respectively (e.g., button, decorative thread, and buttonhole reinforcement sewing). By combining different types of thread guides, different areas or different types of sewing operations can be completed; at the same time, the operator can directly select the corresponding thread guide according to the sewing needs of different areas without changing the device or readjusting the fabric piece position, saving time. Furthermore, the stitching hole 8 is sandwiched between a uniformly spaced and discontinuous second stitching groove 7 and a uniformly continuous second stitching groove 7. Positioning the stitching hole 8 between two different types of second stitching grooves 7 makes its positioning more precise, helping to accurately determine the buttonhole's location and reducing positional shifts caused by fabric or sewing errors. This makes it suitable for placket structures of different design specifications, allowing the device to be compatible with fabrics of different sizes or styles, thus expanding its applicability. Even further, the diameter of the stitching hole 8 is smaller than the button's diameter. This smaller diameter restricts the button's movement or rotation during sewing, improving its stability.

[0036] like Figure 1 As shown, to improve operational visibility, in some embodiments, the first cover plate 1, the first base plate 2, the second cover plate 5, and the second base plate 6 are all made of transparent and flexible materials. The transparent material allows the operator to observe the sewing process of the placket pieces in real time. The alignment of the upper and lower pieces can be observed through the transparent first cover plate 1 and the second cover plate 5, facilitating adjustments to their positions and ensuring precise stitching along the seam guide, thus improving operational accuracy. The use of flexible materials effectively reduces pressure marks or wear on the fabric, making it suitable for various fabrics (such as cotton, silk, or other easily damaged fabrics), thus expanding the applicability of the device. The first cover plate 1, the first base plate 2, the second cover plate 5, and the second base plate 6 can all be, but are not limited to, using PVC transparent materials; no specific limitation is made here.

[0037] As shown in Figure 1 In order to improve the manufacturing efficiency of the device, in some embodiments, the sizes of the first cover plate 1, the first bottom plate 2, the second cover plate 5 and the second bottom plate 6 are the same, wherein the same size of the plate can be processed by the same mold or cutting scheme, which simplifies the manufacturing process, shortens the production cycle, reduces material waste and improves production efficiency.

[0038] In combination with Figure 2 , Figure 3 and Figure 4 In order to enhance the structural stability, in some embodiments, the auxiliary garment fly sewing device further comprises a first connecting piece 4, a second connecting piece 9 and a third connecting piece 10, the first connecting piece 4 is arranged at any opposite edge position of the first cover plate 1 and the first bottom plate 2, the second connecting piece 9 is arranged at any opposite edge of the second cover plate 5 and the second bottom plate 6, and the third connecting piece 10 is arranged between the side of the second cover plate 5 away from the second bottom plate 6 and the side of the first cover plate 1 away from the first bottom plate 2, wherein the first connecting piece 4, the second connecting piece 9 and the third connecting piece 10 can effectively connect each component together, avoid loosening, displacement or deformation of the device during use, the first connecting piece 4 and the second connecting piece 9 enhance the clamping strength between the first cover plate 1 and the first bottom plate 2, the second cover plate 5 and the second bottom plate 6, ensure that the pattern piece can be firmly fixed, and the third connecting piece 10 can fix the relative position of the first cover plate 1 and the second cover plate 5, so as to keep the sewing track of the upper piece pattern and the lower piece pattern consistent, and ensure the alignment accuracy between the buttonhole and the button. Further, the first connecting piece 4, the second connecting piece 9 and the third connecting piece 10 all include a rubber strip or a magic tape, wherein the first connecting piece 4, the second connecting piece 9 and the third connecting piece 10 designed as a rubber strip or a magic tape can easily complete quick connection and disassembly without additional tools or complex operation, saving time and improving use efficiency.

[0039] In order to further prevent the displacement of the upper piece and the lower piece, in some embodiments, the auxiliary garment fly sewing device further comprises a first fastener and a second fastener, the first fastener is arranged between the first cover plate 1 and the first bottom plate 2, and the second fastener is arranged between the second cover plate 5 and the second bottom plate 6. The first fastener is used to fix the relative position between the upper piece, the first cover plate 1 and the first bottom plate 2, and the second fastener is used to fix the relative position between the lower piece, the second cover plate 5 and the second bottom plate 6. By fixing the relative position of the upper piece and the lower piece, the first fastener and the second fastener can effectively prevent the displacement of the piece during sewing, ensure the alignment accuracy between the pieces, effectively avoid the misalignment between the upper piece and the lower piece, and ensure the flatness and accuracy of the stitching line. Further, the first fastener and the second fastener each comprise a magnetic attraction element, which is not limited by the type and thickness of the material and can effectively adapt to various fabrics and materials. Even on thick fabrics, it can provide stable adsorption force, and the quick adsorption and disassembly characteristics of the magnetic attraction element can greatly shorten the time of each operation and improve the working efficiency of the production line.
