  "abstract": "This application belongs to the technical field of fittings for photography and video recording and digital products and provides an anti-loosening and anti-rotation quick-assembly plate for photographic and digital products, including a quick-assembly plate and a large screw. A storage groove is formed in a lower side of the quick-assembly plate, and the large screw is disposed within the storage groove. An anti-loosening fastening assembly for preventing loosening of photographic equipment is disposed between the large screw and the quick-assembly plate, and includes a connection hole formed in a head of the large screw, a positioning hole formed in an inner top surface of the storage groove, and a fastener threadedly connectable between the connection hole and the positioning hole. This application solves the problem that a traditional quick-assembly plate becomes loose from photographic equipment in use.",
