PURPOSE: A clamping apparatus of a printed circuit board(PCB) is provided to prevent the swing of the PCB when a conveyer moves by making an elevating guide installed on a lower portion of a belt support all points of the belt. CONSTITUTION: A connecting block(20) is connected to a road(11) of a driving cylinder(10) to perform a linear motion. A connecting link(30) is connected to the connecting block(20) on the way to perform the linear motion. A rotational block(40) is installed on both ends of the connecting link(30) so as to rotate. An elevating bearing is fixed to the rotational block(40) to be installed on a belt frame(50) so as to elevate, and elevates an elevating guide(60) provided on a lower portion of a belt. The driving cylinder(10) is fixed on the belt frame(50) to be provided on an upper portion of the connecting link(30).
