The invention discloses a fastening nail and a manufacturing method thereof. The fastening nail comprises a nail head arranged on a substrate. A protective film is also arranged on the substrate, and wraps the substrate. The protective film is arranged at the bottom, two sides and outer edges of the top of the substrate. The nail head is stamped through the substrate and then bent, and the lateral surface of the nail head is provided with teeth. The top of the nail head is triangular, and has a smaller upper part and a larger lower part. The end part of the substrate is cambered, square or trapezoidal. The manufacturing method comprises the following steps of: manufacturing the substrate according to dimensional requirements, injecting the melting charge of the protective film into a material trough, inserting the substrate into one end of the material trough, and pulling the substrate out of a material outlet at the other end of the material trough to make the melting charge of the protective film closely attached to the substrate of the substrate. In the fastening nail, the protective film is also arranged on the substrate, and the sharp edges of the substrate can be wrapped in the protective film, thereby avoiding the sharp edges of the substrate from scraping or cutting a user or the properties of the user to improve safety performance; and the fastening nail and the manufacturing method thereof have the characteristics of operating flexibility, low manufacturing cost and wide application range.
Description
technical field [0001] The invention relates to a fastening nail, in particular to a fastening nail and a manufacturing method thereof. Background technique [0002] Chinese Patent Document No. CN 2444493Y disclosed a tabletop for entertainment and catering with decorative nails on August 29, 2001.
