Abstract
A pivot structure with bidirectional rotary positioning is arranged at the connection between the mainframe and the cover body of an electronic device, comprising a fixed base, a cam, a rotary base, a run-through connection axis, and an elastic body; wherein, the run-through connection axis is used for run-through connection with the fixed base, the cam and the rotary base, with an elastic clamping force between the elastic body and the rotary base. The chock blocks and the protruding blocks that match with each other are arranged on the corresponding end surface of the fixed base, the ram and the rotary base respectively, to make rotary base perform the bidirectional rotary positioning relative to the fixed base. Therefore, the rotary base implements the bidirectional rotary positioning clockwise and anticlockwise relative to the fixed base, in order to efficiently avoid the rupture of the wires that run through the inner pivot due to the excessive torsion.
