Patent ID: 8065780

Claim:
A collapsible device comprising: a main body; a cover; and a hinge comprising: a first connecting member comprising a clamping protrusion; a second connecting member defining a through hole; a sleeve member fixed to the second connecting member, the sleeve member defining a spiral slide groove in a circumference of the sleeve member from a first end to a second end of the sleeve member, to slidably receive the clamping protrusion of the first connecting member for driving the second connecting member to move transversely relatively to the first connecting member to move; a shaft slidably mounted to the first connecting member and comprising a fixing portion, wherein the fixing portion is rotatably passed through the sleeve member and the through hole of the second connecting member; and a fastener fixed to a distal end of the fixing portion to prevent the sleeve member and the second connecting member from disengaging from the shaft; wherein the first connecting member is fixed to the main body, and the second connecting member is fixed to the cover; the second connecting member defines a first fixing slot and a second fixing slot, two clamping posts extend from an end surface of the sleeve member, engaging with the first and second fixing slots, respectively; when during the rotation of the cover relative to the main body via the hinge, the cover is synchronously moved transversely relative to the main body along the axial direction of the hinge.
