Abstract
The present disclosure discloses a cord tightening and loosening device, a shoe, a glove, a medical protective equipment and a storage device. The cord tightening and loosening device includes a rotary knob, a pawl disc, a base, a reel and a chassis. When the first meshing part is meshed with the second meshing part and the rotary knob rotates in a first clock direction, the rotary knob can drive the pawl disc to rotate, and then the pawl disc drives the reel to rotate, so that the cord tightening and loosening device can be in a tightening state and the cord can be wound around the winding part to tighten the cord.
