Patent attributes
The present invention relates to a nail assembly having one or more double-pin nails. Each nail includes a nail body and two nail pins extending from the nail body. Each nail pin has a tail end having at least one inclined face formed as a nail edge, where the inclined face is provided with at least one of a concave structure and a convex structure. The concave structure includes one or more grooves, and the convex structure includes one or more tenons. The assembly of double-pin nails having nail pin inclined faces provided with at least one of the concave and convex structures enables, after entering an object, the two nail pins of a double-pin nail are staggered to interlock with each other, thereby effectively connecting the object firmly with a strong anti-pull capability, and having desirable economic and technical benefits.
