Abstract
A fastener structure includes a body portion, a control portion and a fastening portion. The control portion is movably fitted to the body portion. The control portion has a head portion and a limiting portion. The fastening portion is movably disposed at the body portion. The limiting portion is adapted to limit the fastening portion. Therefore, the body portion is disposed at the second object, and the control portion causes the fastening portion to be coupled to or separated from the first object, so as to couple together and separate at least two objects repeatedly and rapidly.
