[0024] Furthermore, as a preferred embodiment, the first mold 4 also includes a fixing plate 404, which is generally C-shaped and positioned above the first base plate 401. A first arc-shaped plate 402 is located on one side of the fixing plate 404. The drive mechanism 3 includes a cylinder 301 and a connecting rod 302. The cylinder 301 is mounted on the movable plate 2, and one end of the connecting rod 302 is connected to the fixing plate 404. See also... Figure 2 and Figure 3 As shown, the fixing plate 404 is used to connect the first base plate 401 and the connecting rod 302. The connecting rod 302 is generally arranged in a "︿" shape. The first mold 4 is located below the movable plate 2. In this embodiment, the first base plate 401, the first arc plate 402, the first horizontal plate 403 and the fixing plate 404 can be integrally arranged.

[0025] Furthermore, as a preferred embodiment, the movable plate 2 is provided with a groove 10, and a slider 12 is disposed within the groove 10. The output end of the cylinder 301 is connected to the slider 12, and the other end of the connecting rod 302 is connected to the slider 12. In this embodiment, a guide rod can be disposed inside the groove 10. The two ends of the guide rod are fixedly connected to the inner walls of both sides of the groove 10. The guide rod is disposed along the length direction of the groove 10. A guide hole is disposed on the slider 12, and the guide rod passes through the guide hole, so that the slider 12 will not detach from the groove 10 when sliding within the groove 10. Through the arrangement of the slider 12, the groove 10, and the guide rod, the movement of the slider 12 is made more stable, thereby ensuring the stability of the movement of the connecting rod 302 and avoiding wobbling. The slider 12 can be L-shaped, with one end of the slider 12 located inside the groove 10 and the other end of the slider 12 extending out of the groove 10 for connection with the piston rod of the cylinder 301.

[0026] Furthermore, as a preferred embodiment, the second mold 5 includes a second base plate 501, a second arc-shaped plate 502, and a second horizontal plate 503. The second arc-shaped plate 502 is disposed at the upper end of the second base plate 501, and the second horizontal plate 503 is disposed at one end of the second arc-shaped plate 502. The second horizontal plate 503 is parallel to the second base plate 501. The second base plate 501 can be fixed to the worktable by bolts, and the second base plate 501, the second arc-shaped plate 502, and the second horizontal plate 503 can be integrally connected.

[0027] Furthermore, as a preferred embodiment, a first groove 405 is formed between the first base plate 401, the first arc-shaped plate 402, and the first horizontal plate 403, and a second groove 504 is formed between the second base plate 501, the second arc-shaped plate 502, and the second horizontal plate 503. In use, the first base plate 401 can enter the second groove 504, and the second horizontal plate 503 can enter the first groove 405. This allows the fabric to be automatically folded into a Z-shape, and in conjunction with the settings of the sewing machine, the fabric is driven forward to sew the Z-shaped area on the fabric.

[0028] For details, please refer to Figure 3 As shown, taking the Z-shaped area on the fabric as an example, the Z-shape consists of a first included angle on the upper side and a second included angle on the lower side. The first included angle of the Z-shape is located within the first groove 405, at which point the second horizontal plate 503 extends into the first included angle. The second included angle of the Z-shape is located within the second groove 504, and the first bottom plate 401 extends into the second included angle. In use, one end of the fabric is first manually folded into a Z-shape, and then one end of the fabric is laid flat on the second bottom plate 501, so that the second horizontal plate 503 is inserted into the first included angle, while the second included angle is located within the second groove 504. Then, the connecting rod 302 is driven by the cylinder 301. The horizontal movement causes the connecting rod 302 to move the first mold 4 closer to the second mold 5. At this time, the first base plate 401 will automatically insert into the second angle of the Z-shape, and the first horizontal plate 403 will press down on the upper surface of the Z-shape. In conjunction with the sewing machine settings, the fabric can be moved automatically when sewing. The cooperation between the first mold 4 and the second mold 5 allows the fabric to automatically enter the first slot 405 and the second slot 504 to form a Z-shaped structure. At this time, no manual operation is required, which can ensure that the Z-shape formed after sewing is neat and uniform, improving product quality and work efficiency.

[0029] Furthermore, as a preferred embodiment, an "L"-shaped limiting plate 11 is provided on one side of the movable plate 2, forming a mounting groove between the limiting plate 11 and the movable plate 2. One end of the connecting plate 1 is installed in the mounting groove by a first bolt 9. A second oblong hole 8 is provided on the limiting plate 11, and a bolt hole that mates with the first bolt 9 is provided on one end of the connecting plate 1. By adjusting the position of the first bolt 9 in the second oblong hole 8, the position of the movable plate 2 relative to the connecting plate 1 can be adjusted, thereby adjusting the horizontal position of the first mold 4.
