Abstract:
The present invention provides a fastening device, comprising a case, a spool, and a knob. The case comprises a case body and a base, the case body comprises an accommodating space and two threading holes, and the two threading holes are communicated with the accommodating space; the base is detachably connected to the case body and comprises a continuous annular wall. The spool is accommodated in the accommodating space, and a lace is wound on the spool after passing through the two threading holes; the knob is provided on the case. After the base is connected to the case body, the continuous annular wall surrounds the bottom edge of the case body, and the knob is rotated relative to the case to drive the spool to tighten the lace. In this way, the structure in which the continuous annular wall surrounds the bottom edge of the case body allows for more stable assembly of the base and the case body, thereby improving structural reliability.
