1. A dust-proof device, for protecting an insertion interface of an optical receptacle, comprising:
a coupling portion, having a positioning structure disposed on a side of the coupling portion; and
a flexible arm, an end of the flexible arm connected to the coupling portion, wherein the flexible arm swings or scrolls at a connecting portion where the coupling portion is connected to the flexible arm,
wherein the coupling portion has a hollow area, a beam structure is disposed above the hollow area, and a supporting structure is disposed in the hollow area, and one end of the supporting structure is fixed with the beam structure to support the beam structure and prevent the beam structure from being broken when the beam structure is deformed,
wherein the optical receptacle has a coupling base, and the coupling portion is inserted into the coupling base to prevent the coupling base from being contaminated in the optical receptacle,
wherein the coupling portion has a notch, which allows the coupling base to insert and is disposed at an opposite side of the flexible arm.
