Abstract
A rotary mechanism includes a base (10), a cover (30), a torsion spring (40) and a locking module (20). The rotary 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 from rotating relative to the base. When the cover overcomes the limitation of the locking module, the cover can automatically rotate relative to the base due to the torsion spring.
