Abstract
A pivoting mechanism for an electronic device includes a pivot shaft, a first connecting member disposed on the pivot shaft for being connected with a support of the electronic device, a second connecting member disposed on the pivot shaft for connected with a main body of the electronic device, and a torque adjusting assembly. The torque adjusting assembly includes four sleeves and an elastic member through which the pivot shaft is disposed. Each of the sleeves includes at least one protrusion. The protrusion of one of the four sleeves is slidable relative to the protrusion of another sleeve for adjusting an amount of deformation of the elastic member. A portable electronic device including a main body, a support and the pivoting mechanism is provided.
