A ratchet part (7124) is provided on the base (71), and a ratchet part (751) adapted to the ratchet part (7124) is provided on the winding seat (72). The ratchet part (7124) and the ratchet part (751) cooperate to make the winding seat (72) rotate only in one direction with the base (71). Rotating the winding seat (72) can make the traction rope (6) wind around the winding seat (72). Under the action of external force, the ratchet part (7124) can disengage from the ratchet part (751), so that the traction rope (6) can gradually disengage from the winding seat (72).

8. A posture correction belt according to claim 7, characterized in that: The winding base (72) includes a winding disc (74) and a knob (73) that are movably connected. The traction rope (6) is wound on the winding disc (74). A ratchet (751) is provided on the knob (73) and restricts the relative rotation of the knob (73) and the base (71). The winding disc (74) and the knob (73) are respectively rotatably mounted on the base (71). The winding disc (74) and the knob (73) are respectively provided with a first positioning part (741) and a second positioning part (731) and make the winding disc (74) and the knob (73) rotate synchronously. Under the action of external force, the knob (73) can slide relative to the base (71) to disengage the first positioning part (741) and the second positioning part (731), so that the winding disc (74) can rotate freely with the base (71).

9. A posture corrector belt according to claim 8, characterized in that: The two ends of the traction rope (6) are connected to the winding seat (72). The adjusting device (7) can control the two ends of the traction rope (6) to wind around the winding disc (74) respectively. Alternatively, the middle part of the traction rope (6) is connected to the winding seat (72). The adjusting device (7) can control the traction ropes (6) on both sides of the connection position with the winding disc (74) to wind around the winding disc (74) respectively. The traction seat (5) is provided with several reversing wheels (52). The traction rope (6) is guided by the reversing wheels (52) and the two strands of traction rope (6) between the traction seat (5) and the winding disc (74) are arranged in parallel.

10. A posture correction belt according to claim 1, characterized in that: The back panel (1) is provided with several elastic reinforcing rods (8), which extend vertically and are located on one side of the traction seat (5) and the connecting seat (4).
