Abstract
A rotary mechanism includes a base (), a cover (), a torsion spring () and a locking module (). The cover is rotatably mounted to the base. Two ends of the torsion spring are fixed with the base and the cover respectively. The locking module limits the cover rotation relative to the base. When the cover overcomes the limitation of the locking module, the cover is automatically rotated relative to the base by the torsion spring.
