Abstract
A cord winding module, comprising a rotary wheel (9) on which a cord (11) is wound and a stop button (4) working cooperatively with the rotary wheel. The cord winding module further comprises a spring wire (5) working cooperatively with the stop button as an elastic support device, and the stop button automatically brakes the rotary wheel under the action of the elastic force of the spring wire and prevents the rotary wheel from retracting the cord. The spring wire has an arc shape, or exhibits an arc shape when pre-pressed and deformed by the stop button.
