Abstract: A fastening device includes a case, a spool, a plurality of ratchet teeth, an incremental releasing set and a knob. The incremental releasing set includes a ratchet arm and an operated portion, the ratchet arm is selectively engaged with at least one of the ratchet teeth, and the operated portion is linked with the ratchet arm. The knob is disposed at the case. The ratchet arm is engaged with at least one of the ratchet teeth to prohibit the spool from rotating in a releasing direction, and as the knob is rotated in a tightening direction, the ratchet arm is disengaged from at least one of the ratchet teeth to allow the spool to tighten the lace; as the operated portion is operated, the ratchet arm is disengaged from at least one of the ratchet teeth, such that allows the lace to be incrementally released.

Abstract: A fastening device includes a case, a spool, a plurality of ratchet teeth, an incremental releasing set and a knob. The incremental releasing set includes a ratchet element and a swinging arm, the ratchet element includes a ratchet arm and a linking portion, the ratchet arm is selectively engaged with at least one of the ratchet teeth, and the swinging arm is abutted against the linking portion. The ratchet arm is engaged with at least one of the ratchet teeth to prohibit the spool from rotating in a releasing direction; as the knob is rotated in a tightening direction, the ratchet arm is disengaged from at least one of the ratchet teeth to allow the spool to tighten the lace; as the swinging arm is operated, the lace is incrementally released; as the knob is pulled up or rotated in the releasing direction, the lace is fully released.
