Abstract
A bidirectional pivot structure includes a horizontal rotation axis module, a rotation switching device and a vertical rotation axis module. The rotation switching device is pivotally connected to the horizontal rotation axis module and the vertical rotation axis module. The vertical rotation axis module includes an aligning element, a rotation position limiting element, a stabilizing element, a flexible element and a locking element. The rotation position limiting element has a position limiting convex dot and a position limiting arc fitted to a guide rail and a position limiting protrusion of the aligning element for limiting the rotary angle of the vertical rotation axis module. The stabilizing element has a positioning convex dot and a stabilizing protrusion fitted to the positioning holes of the aligning element to maintain a frictional stability. By the design of the aligning element, rotation position limiting element and stabilizing element, the effect of limiting and positioning the vertical rotation axis module can be achieved.
