Reverse osmosis membrane disassembling and assembling tool

The invention relates to a disassembling and assembling tool, and particularly relates to a reverse osmosis membrane disassembling and assembling tool. The reverse osmosis membrane disassembling and assembling tool comprises a supporting plate and a screw rod, wherein the supporting plate is used for being tightly attached to the end, provided with a membrane housing end cover, of a tubular membrane housing, and the screw rod extends into the tubular membrane housing; at least two through holes allowing the screw rod to penetrate through are formed in the supporting plate; the through holes correspond to inner threaded holes in the membrane housing end cover in a one-to-one mode; one end of the screw rod penetrates through the through holes to be connected into the corresponding inner threaded holes in the membrane housing end cover; and an adjusting nut is mounted at the other end of the screw rod. According to the reverse osmosis membrane disassembling and assembling tool, the membrane housing end cover can
