Clamping device for connection plate on a quick connector

Disclosed in the invention is a clamping device for a connection plate on a quick connector. The clamping device comprises six connection plates, an upper clamping component, and a lower clamping component. One ends of the connection plates are provided with connection through holes; and another ends of each two connection plates are overlapped each other. The upper clamping component includes three upper ceramic plates, an upper pressing plate, and an adjusting plate, wherein the three ceramic plates are on a same plane and are separately arranged on the overlapping positions of the connection plates. The lower clamping components consists of three lower ceramic plates, an isolation plate and a lower pressing plate, wherein the three lower ceramic plates are on a same plate and are respectively arranged below the overlapping positions of the connection plates. According to the invention, fixation between two connection plates can be effectively strengthened and the two connection plates can be pressed and clamped tightly, so that disassembly and assembly of the connection plates become convenient.
