A magnetic attraction type cord winding module, comprising a rotary wheel (9) on which a cord (10) is wound and a stop button (4) working cooperatively with the rotary wheel (9). The cord winding module further comprises at least one pair of magnet blocks, and the at least one pair of magnet blocks comprise a first magnet (3) disposed on the stop button (4) and a second magnet (5) disposed on the rotary wheel (9). The stop button (4) automatically brakes the rotary wheel (9) under the action of an attractive force or a repulsive force of the magnet blocks and prevents the rotary wheel (9) from retracting the cord (10). The magnet block disposed on the stop button (4) does not protrude from the upper surface of the stop button (4), and the magnet block disposed on the rotary wheel (9) is flattened.
