Abstract

A linkage mechanism includes a pivoting assembly, a cam, a sliding assembly and at least one linkage. The cam pivots coaxially with the rotating axis of the pivoting assembly. A leaning element is located on one side of the cam. A sliding frame pivots the leaning element and has at least one limiting area. The linkage includes a main body portion, a first linkage portion protruded beyond the limiting area and a second linkage portion. When the pivoting assembly drives the cam to pivot from a first position to a second position, the cam pushes against the leaning element to slide the sliding frame in a first direction relative to a plate, and the limiting area interferes with the first linkage portion of the linkage to rotate the main body portion in a first clock direction to allow the second linkage portion to provide a thrust in a second direction.
