Patent ID: 7837159

Claim:
A positioning mechanism, comprising: a fixed frame; a first buckling element fixed to a first position of the fixed frame; a second buckling element fixed to a second position of the fixed frame; and a rotary component with a positioning pin; wherein the rotary component is connected to an object and pivoted to the fixed frame, such that the object and the rotary component are synchronously rotated with respect to the fixed frame; wherein the first buckling element has a pair of first suspending arms and two opposite first flanges separating a first gap smaller than a diameter of the positioning pin, and the second buckling element has a pair of second suspending arms and two opposite second flanges separating a second gap smaller than the diameter of the positioning pin; and wherein the object is in a first positioning state when the positioning in is clamped by the first flanges, and in a second positioning state when the positioning pin is buckled to the second buckling element through the elasticity of the second suspending arms respectively.
