Document Type and Number:
WIPO Patent Application WO/2018/086068
Kind Code:
A1
Abstract:
Disclosed are a fastening device (100) and an installation method for a thread (600) thereof. The fastening device (100) is composed of a housing (200), a bobbin (300), a knob (500) and a detent unit (400), wherein the housing (200) contains a snap-fit portion (250); the bobbin (300) is provided on the housing (200) and is wound around by the thread (600); the knob (500) contains an embedding and clamping portion (540) and engages with the snap-fit portion (250) such that the knob (500) is coupled to the housing (200); and the detent unit (400) is coupled to the knob (500) and is driven by the knob (500). Rotating the knob (500) relative to the housing (200) drives the detent unit (400) to switch from a first position to a second position. The detent unit (400), when in the first position, prevents the bobbin (300) from rotating in a loosening direction (A1), whereas the detent unit (400), when in the second position, allows the bobbin (300) to rotate in the loosening direction (A1). The invention can achieve the objectives of simplifying the structure of the fastening device (100) and maintaining the fastening capability of the fastening device (100).
