[0010] Preferably, the metal buckling strip is provided with anti-skid fine lines on the side surface close to the nail core.

[0011] Compared with the prior art, the utility model has the beneficial effects that:

[0012] By evenly arranging a plurality of corrugated grooves inside the rivet sleeve, the entire rivet sleeve can be more easily deformed at multiple ends after being extruded by the rivet head, the rivet joint can be completed, meanwhile, the excess gap of the workpiece mounting hole can be filled by extruding outward, so that the rivet sleeve cannot rotate, and the rivet joint effect is more stable.

[0013] By arranging an installation groove in the rivet sleeve seat and arranging a rubber ring in the extrusion groove, when the rivet gun is used for riveting, the rivet gun applies pressure to the rivet sleeve seat, the rubber ring in the extrusion groove is extruded and deformed outward of the opening, and the rubber ring is tightly attached to the nail core, so that the nail core and the rivet sleeve are tightly attached to each other.

[0014] By arranging a hidden groove in the opening edge of the rivet sleeve seat and arranging a metal buckling strip in the hidden groove, when the rivet gun is used for riveting, the metal buckling strip is extruded and deformed when the rivet gun applies pressure to the rivet sleeve seat, so that the metal buckling strip is tightly attached to the outer side of the nail core, and good stability is ensured.
