Patent ID: 8908858

Claim:
A rotating mechanism for rotatably connecting a first body with a second body, the first body comprising a pair of sidewalls, the second body comprising a pair of connecting arms, the rotating mechanism comprising: a first connecting piece rotatably connecting one of the connecting arms to one of the sidewalls; a second connecting piece rotatably connecting the other one of the connecting arms to the other one of the sidewalls; a resilient element connecting the second connecting piece with the sidewall and providing a restoring force to the second connecting piece along a direction perpendicular to the sidewall; and an angle positioner fixed on one of the sidewall and sleeved on the first connecting piece; wherein the angle positioner comprises a pair of angle positioning projections and defines a positioning gap between the angle positioning projection, the angle positioning projections are rotated about the first connecting piece to adjust an extending direction of positioning gap, the first connecting piece comprises a pair of lugs formed at an end of the first connecting piece, and the lugs are pulled into the angle positioning gap by the restoring force when the first connecting piece are rotated to a position where the lugs are aligned with the angle positioning gap.
