When the hinged parts of the fixed splint 12 and the movable splint 13 are away from the employee's position, the employee can clamp and fix the front end of the fabric to be processed by the fixed splint 12 and the movable splint 13 extending outward. A handle 22 is connected to the upper surface of the movable splint 13, and the movable splint 13 is closed onto the top of the fixed splint 12 by the handle 22 to press the fabric on the upper surface of the fixed splint 12.

[0022] Specifically, a first motor 6 is installed on the surface of one side of the processing table 4, and a first rotating rod 7 is rotatably connected inside the groove 5. One end of the first rotating rod 7 is rotatably connected to the side wall of the groove 5 via a bearing, and the other end of the first rotating rod 7 extends to the inside of the processing table 4. The extended end of the first rotating rod 7 is connected to the shaft end of the first motor 6. An active rotating wheel 8 is sleeved on the outside of the first rotating rod 7, and a second rotating rod 9 is rotatably connected inside the groove 5 at the rear end of the first rotating rod 7. Both ends of the second rotating rod 9 are rotatably connected to the side wall of the groove 5 via bearings. A driven rotating wheel 10 is sleeved on the outside of the second rotating rod 9, and a conveyor belt 11 is sleeved on the outside of the active rotating wheel 8 and the driven rotating wheel 10. The first rotating rod 7 is driven to rotate by the first motor 6, and the first rotating rod 7 drives the active rotating wheel 8 to rotate. The active rotating wheel 8 drives the conveyor belt 11 to rotate, and the rotating conveyor belt 11 drives the movable splint 13 and the fixed splint 12 to move.

[0023] Furthermore, a support plate 3 is connected to the surface of one side of the overlock machine body 1 below the processing table 4, and columns 19 are connected to both sides of the top of the support plate 3. An adjusting rod 20 is movably connected inside the column 19. The top of the adjusting rod 20 passes through the top of the column 19 and extends to the outside of the column 19. The extending end of the adjusting rod 20 is connected to the bottom end of the processing table 4, and the processing table 4 is supported by the column 19 and the adjusting rod 20, thereby improving the stability of the processing table 4; a first threaded hole is opened on the upper part of the surface of one side of the column 19, and a plurality of second threaded holes are opened on the surface of one side of the adjusting rod 20.

When the height of the processing table 4 is adjusted, the bolt 21 is passed through the first threaded hole on the outer surface of the column 19 and the second threaded hole on the outer surface of the adjusting rod 20, so that the column 19 and the adjusting rod 20 are fixedly connected. Because the fixed splint 12 and the movable splint 13 are L-shaped structures, the fabric to be hemmed is placed on the upper surface of the fixed splint 12, and one side edge area of ​​the fabric to be hemmed can pass over the fixed splint 12, thereby making the area to be hemmed on the processing table 4 and below the seam assembly 2, The frontmost end area is placed on the L-shaped convex part of the fixed splint 12, and the entire fabric is tightened and flattened to prepare for the subsequent hemming. The movable splint 13 is closed onto the top of the fixed splint 12 through the handle 22 to press the fabric on the upper surface of the fixed splint 12. The entire fabric area to be hemmed is tightened and flattened, and the magnetic connection between the first magnet 16 and the second magnet 18 is improved to improve the stability of the movable splint 13 covering the upper surface of the fixed splint 12. The first motor 6 drives the first rotating rod 7 to rotate, and the first rotating rod 7 drives the active rotating wheel 8 to rotate, and the active rotating wheel 8 drives the conveyor belt 11 to rotate. The rotating conveyor belt 11 drives the movable splint 13 and the fixed splint 12 to move, so that the fabric is driven by the movable splint 13 and the fixed splint 12 to move and is hemmed with the help of the upper sewing assembly 2, thereby improving the safety of the sewing machine body 1.
