Linkage mechanism

A linkage mechanism, adapted to be assembled on a plate, the linkage mechanism comprising:

• a pivoting assembly, comprising a rotating axis;
• a cam, sleeved on the rotating axis to pivot coaxially with the rotating axis;
• a sliding assembly, assembled on the plate and comprising a leaning element and a sliding frame, wherein the leaning element is located on one side of the cam, and the sliding frame pivots the leaning element and has at least one limiting area;
• and
• at least one linkage, assembled on the plate and located in the limiting area of the sliding frame, the linkage comprising a main body portion, and a first linkage portion and a second linkage portion connecting the main body portion, wherein the first linkage portion protrudes beyond the limiting area,
• wherein 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 the plate, and the limiting area of the sliding frame 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, and the first direction is different from the second direction.
