ABSTRACT:
A collapsible device includes a base, a cover, and a hinge. The hinge includes a first connecting member fixed to the base, a second connecting member defining a through hole, a sleeve member fixed to the second connecting member, a shaft movably mounted to the first connecting member, and a fastener. The sleeve member defines a spiral slide groove therein. A clamping protrusion extends from the first connecting member for slidably engaging in the slide groove. The shaft includes a fixing portion rotatably passed through the sleeve member and the through hole. The fastener is fixed to a distal end of the fixing portion. The second connecting member is fixed to the cover. During the rotation of the cover relative to the base via the hinge, the cover is synchronously moved transversely relative to the base along the axial direction of the hinge.
