Abstract
A lace tightening and loosening device, wearable clothing, and a storage device are provided. The lace tightening and loosening device includes a base, a spool, a pawl disc, a dial and a connecting structure. When the dial is rotated in a first direction, the driving member drives the pawl disc to rotate in the first direction and drive the connecting structure to rotate, thereby driving the spool to rotate in the first direction to tighten a lace; when the dial is rotated in a second direction opposite to the first direction, the driving member drives the pawl to be separated from the first meshing part, so that the pawl disc rotates in the second direction and drives the connection structure to rotate.
