Ring-lock scaffolding is easy to build .

One end of the standard can be inserted into the other end of other standard. Every ledger has two connectors at both ends for connecting Rosette node and diagonal brace. The connector has two inserted pins and the three are integrated into a whole by rivets. The inverted pins can move up and down easily but can"t be pulled out. They are easy to use and can effectively avoid the problem that small pins lost easily.
