A two-string winding fastener file case comprising a longitudinal string (X) planted onto a file case flap (H2), a longitudinal string (t) planted at the right side at the bottom within a case body (H) and extending outward, and rivet spacers (X1 and X2) arranged on the flap, constituting winding fasteners (Y1 and Y2), and used for fixing the case body (H) and the case cover (H1). During use, winding straps (t1 and t2) are correspondingly wrapped under the winding spacers on the corresponding rivets, thus implementing tight strapping. The file case is structurally simple and can be firmly strapped. |
