Anti-slip and quick-detach fastener structure

An anti-slip and quick-detach fastener structure for using with an annular strap, wherein the annular strap comprises a fixed end, a first inner edge located on an inner side of the fixed end, a free end distant from the fixed end, and a second inner edge located on an inner side of the free end, the anti-slip and quick-detach fastener structure comprises:

• a fixing ring, comprising a first fixing section surrounded by the fixed end to constrain the first inner edge, a second fixing section spaced apart from and opposite to the first fixing section, and an inserting space located between the first fixing section and the second fixing section;
• and
• a dynamic friction member, comprising a first friction section surrounded by the free end to constrain the second inner edge, an operating section connected with the first friction section, and a connecting section operably connecting with the first friction section and the fixing ring;
• wherein the free end is inserted into the inserting space, the first friction section and the second fixing section form a dynamic friction state to jointly clamp the free end, and the first friction section loses the dynamic friction state with the second fixing section and releases the free end when the first friction section is forced to rotate.
