A fastener structure includes a body and a fastening portion. The fastening portion is provided on one end of the body, and includes a neck configured to be receivingly fastened into, assembled into or fitted with a coupling counterpart. Thus, the handle and the coupling counterpart may be assembled during use, and the handle may be removed from the coupling counterpart when not in use, achieving effects of easy operation and collision prevention. Further, the fastener structure may be assembled to a first object, and be fastening connected to a second object or removed from the second object so as to complete coupling or separation of at least two objects, achieving the effect of repeated quick coupling and separation.
