[0029] Such as figure 1 , 2 A kind of installation method that improves anti-rotation ability blind rivet nut shown in 4, comprises the following steps:
[0030] A. Open a circular installation hole 5 on the plate 2 to be installed with the blind rivet nut 1, and open a rounded gap 4 at the edge of the installation hole 5, and the radius of the rounded gap 4 is 1mm;
[0031] B. Insert the rivet gun into the inner cavity of the rivet nut 1, the rivet gun is threaded with the rivet nut 1, and the rivet gun drives the rivet nut 1 to penetrate into the installation hole 5;
[0032] C. The rivet gun pulls the rivet nut 1 to the side away from the plate 2, so that the rivet nut 1 deforms and forms a protrusion 3 on the end surface of the plate 2, and the protrusion 3 is close to the end surface of the plate and close to the position of the fillet gap 4 Expand outward, so that the contact surface between the rivet nut 1 and the plate 2 is no longer a complete cylindrical surface, a...
