Easy door stopper / door stopper

The door stopper which is fixed to keep open door, has been maintained by the same structure without change. It is however; a bit inconvenience when to use because the structure has a problem.
I suggest that you adapt to Easy door stopper which rotate in a 360-degree arc to solve the inconvenience.
Normally, people cannot feel inconvenience from this action even it is very inconvenience because they get used for a long time.
Ordinary times, however; it appears inconvenience when people use.
