Technical Field

[0001] The utility model relates to the technical field of hair embroidery, in particular to a small-sized hair embroidery tool which is convenient to carry. Background Art

[0002] Hair embroidery is a folk handicraft that uses human hair with natural color as material and needles as tools to create artistic images on a smooth satin surface. Hair embroidery combines painting and embroidery, using the natural color and characteristics of hair to create artworks with rich folk connotations and unique charm of conveying emotions.

[0003] The production process of hair embroidery is complicated and requires multiple steps such as design, material selection, and embroidery. The designer first draws the design on the satin, and then selects the hair of the appropriate color for embroidery. Hair embroidery uses a variety of needle techniques such as straight needle series, curved needle series, and shaped needle series, making the works elegant in color and rich in layers. Hair embroidery works are not only ornamental, but also become national collection treasures or diplomatic gifts due to their unique materials and craftsmanship.

[0004] In the past, large sitting or standing hair embroidery tools were usually used. However, such large hair embroidery tools are very inconvenient to disassemble and transport, and are not convenient for embroiderers to carry when performing outside. Therefore, it is necessary to design a small hair embroidery tool that is easy to carry to solve the above problems. Utility Model Content
