[0033] like Figure 2 and Figure 3As shown, in this embodiment, the rivet gun 2 is fixedly mounted on the frame plate 23, and a clamp 24 for fixing the rivet gun 2 is provided on one side of the frame plate 23. The front end of the rivet gun 2 is fixedly passed through the corresponding hole of the frame plate 23 for riveting processing. The base 1 is provided with a displacement groove 11 corresponding to the rivet gun 2 to accommodate the lower end of the rivet gun 2. The base 1 is provided with guide rails 12 on both sides of the displacement groove 11. The displacement plate 21 is slidably mounted on the guide rails 12 by a slider. The push cylinder 22 is fixedly mounted on the base 1 and located on one side of the displacement plate 21. The outer end of the output rod of the push cylinder 22 is fixedly connected to the displacement plate 21 through a connecting plate 25 to control the rivet gun 2 to move back and forth.
[0034] The base 1 is provided with a first buffer 13 on one side of the displacement plate 21. The displacement plate 21 is provided with a first impact block 14 that cooperates with the first buffer 13 to limit the forward movement distance of the displacement plate 21.
