During our daily life, it is very convenient for us to use thumbtack, but there is a problem that we can’t pull out the thumbtack easily. Therefore, I design the rotating thumbtack, and we can pull out them easily by rotating them. What‘more, it looks like a clover, so I name it as Clover Thumbtack.
