A cord taking-up and releasing device includes a main body consisting of a housing, a turning knob on a top of the housing, and a seat below the housing; a taking-up and releasing unit received in the housing and including a first shaft connected at an upper end to the turning knob and at a lower end to a retaining gear; and a cord-winding unit mounted on the seat of the main body and including a reel having an upper end engaged with the retaining gear, a lower end rotatably connected to a second shaft, and a middle portion, to which two ends of a cord are tied. Through manipulation of the turning knob, the taking-up and releasing unit brings the cord-winding unit to quickly take up or release the cord tied to the reel without being affected by the length of the cord wound around the reel.
