The invention discloses a fast four-point riveting device, which consists of a positioning mechanism, 4 360 degree distributed lateral riveting mechanisms, a pressing mechanism and a receiving mechanism. The positioning mechanism is used to realize the positioning effect of the adapter. The 4 lateral riveting mechanisms complete riveting of the adapter in four directions, and the clamping mechanism cooperates with the receiving mechanism to promote the movement of the four lateral riveting mechanisms and realize the closing of the adapter. The invention, is simple in structure, convenient in manufacturing, easy and quick to use. It can realize the four-direction rivet adding process simultaneously, and solve the difficult problem that the rivet is not firmly riveted, the mouth part is damaged and the size consistency is poor after the four riveting of the adaptor added, and improve the working efficiency greatly.
