Abstract:
A fastening device including a case unit, a spool, a driving unit, a knob and a connecting unit is provided. The case unit has a radial direction and an axial direction and includes an annular wall. The annular wall surrounds an inner space. The spool is within the inner space and includes an axial space including a large-diameter segment and a small-diameter segment, and the small-diameter segment is connected to the large-diameter segment along the axial direction. The driving unit is disposed above the spool along the axial direction, and the driving unit selectively prohibits the spool from rotating in a loosening direction. The knob is disposed above the driving unit along the axial direction, and the knob is coupled to the driving unit. The connecting unit is connected to the knob, and the connecting unit is disposed within the axial space and limited within the large-diameter segment.
