Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Embodiment 1:

[0026] Please refer to Figure 1-4 A sewing machine for sewing clothes comprises a sewing machine body 1, a U-shaped seat 2 and a connecting plate 5. A thread holder 15 is fixedly connected to the top outer surface of the sewing machine body 1. A plurality of thread holders 16 are fixedly connected to the top outer surface of the thread holder 15. The sewing thread barrel is sleeved on the thread holder 16. An adjusting frame 3 is fixedly connected to the top outer surface of the U-shaped seat 2. A plurality of guide rings 4 are fixedly connected to the top outer surface of the adjusting frame 3, so that the sewing thread passes through the guide ring 4 to perform preliminary position limiting on the sewing thread. A plurality of slide bars 6 are fixedly connected to the outer surface of the connecting plate 5. Slide blocks 7 are movably sleeved on the outer surfaces of the plurality of slide bars 6. Guide frames 8 are fixedly connected to the top outer surfaces of the plurality of slide blocks 7. Guide wheels 9 are rotatably connected to the outer surfaces of the plurality of guide frames 8. The sewing thread passes around the guide wheels 9 to perform further position limiting. A first threaded rod 10 is threadedly penetrated through the outer surface of the adjusting frame 3. The outer surface of the first threaded rod 10 is fixedly connected with a first knob 11, and the outer surface of the first threaded rod 10 away from the first knob 11 is rotatably connected to the connecting plate 5. By turning the first knob 11, the first knob 11 drives the first threaded rod 10 to rotate, and the first threaded rod 10 drives the connecting plate 5 to move, and the position of the connecting plate 5 is adjusted, thereby adjusting the supporting force of the guide wheel 9 on the sewing thread, so that the sewing effect of the sewing thread during sewing is better, and the outer surface of the connecting plate 5 is fixedly connected with a plurality of springs 18, and the plurality of springs 18 are respectively sleeved on the outer surfaces of the plurality of slide rods 6, and the other ends of the plurality of springs 18 are respectively fixedly connected with the plurality of sliders 7.
