Since the placement openings 21 that are connected to the first conveying assembly 6 and the second conveying assembly 19 are opened in four directions on the outer surface of the rotating disk 22, the rivet nut can smoothly enter and leave the placement opening 21. After the rivet nut enters the inside of one of the placement openings 21 through the first conveying assembly 6, the servo motor 26 is started to drive the rotating disk 22 to adjust the angle of 45°, so that the placement opening where the rivet nut is placed is located below the tapping assembly 14, and the first conveying assembly 6 will convey the rivet nut to the inside of the other placement opening 21, and at the same time, the second conveying assembly 19 will be driven to rotate the rotating disk 22 to adjust the angle by 45°.

Since the placement ports 21 that are connected to the first conveying assembly 6 and the second conveying assembly 19 are opened in four directions on the outer surface of the rotating disk 22, the rivet nut can smoothly enter and escape from the placement port 21. After the rivet nut enters the inside of one of the placement ports 21 through the first conveying assembly 6, the servo motor 26 is started to drive the rotating disk 22 to adjust the angle of 45°, so that the placement port where the rivet nut is placed is located below the tapping assembly 14, and the first conveying assembly 6 will transport the rivet nut to the inside of the other placement port 21, and at the same time, the second telescopic rod 23 is started to clamp the limit block 25 into the inside of the placement port 21, and the rivet nut can be tapped. The nut is stuck inside the placement port 21, and then the hydraulic rod 11 is started to tap the rivet nut through the tapping assembly 14. After the tapping is completed, the second telescopic rod 23 drives the limit block 25 to reset, and at the same time the servo motor 26 drives the rotating disk 22 to rotate 45°, so that the tapped rivet nut can be directed to the second conveying assembly 17, and the first telescopic rod 17 is started to push the tapped rivet nut to the second conveying assembly 19 through the push plate 18, and then the rivet nut that enters the placement port 21 and needs to be tapped can be tapped according to the same steps.
