The two side plates of the flip plate 23 are fixedly connected to the outer wall surface of the lower pressure ring column 25 through the fixedly connected connecting plates 24. The upper surface of the lower pressure ring column 25 is fixedly connected to the enlarged ring column 26, and the enlarged ring column 26 is provided with two mutually symmetrical L-shaped card holes 261.

[0029] The enlarged ring column 26 is matched with the plug-in ring column 31 , and the two L-shaped clamping holes 261 on the enlarged ring column 26 are respectively matched with the two clamping hole plates 32 on the same plug-in ring column 31 , and the upper ends of the two L-shaped clamping holes 261 are both set to an open shape.
