[0079] The connecting bolt 83 is installed in the first screw hole and the second screw hole at the same time;

[0080] The first clamping ring 91 and the second clamping ring 92 are simultaneously buckled in the clamping groove 41;

[0081] When the reverse osmosis device needs to be installed or removed, the connecting bolts are removed, the first clamping ring and the second clamping ring are buckled in the clamping groove, and then the connecting bolts are installed to fix and limit the reverse osmosis device.
