Please refer to Figures 1 to 3. The utility model provides a technical solution, a fabric feeding auxiliary guiding device for a sewing machine, which can push and guide the fabric to be sewn, and includes an adapter frame 1, a spring plate 2 and a guide pressing component 3. The adapter frame 1 is fixed to the operating panel of the sewing machine by screws. Of course, a rectangular slot adapted to the adapter frame 1 is reserved on the operating panel of the sewing machine. The adapter frame 1 and the guide pressing component 3 are symmetrically arranged on the operating panel of the sewing machine. The upper surface of the adapter frame 1 is flush with the operating panel of the sewing machine, so that the fabric can slide over the operating panel and the surface of the adapter frame 1. The spring plate 2 and the guide pressing component 3 are installed on the adapter frame 1. The guide pressing component 3 The pressing component 3 not only compresses the fabric but also pushes the fabric to a certain extent. The end of the guiding pressing component 3 is movably connected with the spring plate 2. When the pressure of the guiding pressing component 3 is too large, the spring plate 2 can undergo a certain degree of elastic deformation. The guiding pressing component 3 includes a pull rod 31, a spring 32, a retaining ring 33, an inclined arm 34, a folding frame 35 and a pressing wheel 36.
