1. A vacuum suction device comprising:
a suction plate formed in a disk shape with a predetermined thickness and provided with a disk-shaped insert having a coupling protrusion at a center thereof, the insert being configured to selectively provide suction through a bottom surface thereof;
a rotor formed in a cylindrical shape and having a coupling hole formed through a center thereof and guide protrusions protruding from opposite sides of an outer circumference of the rotor, the rotor being mounted in the center of a top surface of the suction plate by the coupling hole and the coupling protrusion of the insert;
a base member comprising:
a disk-shaped suction plate coupling part configured to accommodate the suction plate in a lower portion thereof; and
a rotor coupling part protruding in a cylindrical shape at a center of a top surface of the suction plate coupling part to allow the rotor to be accommodated therein and to move up and down, the rotor coupling part being provided with a pair of penetrated rotor guide grooves and a pair of penetrated cap coupling grooves at a predetermined point on an outer circumferential surface thereof; and
a cap formed in a wide cylindrical shape with an open bottom and having a through hole in a center thereof, the cap being rotatably mounted on an upper portion of the base member by a pair of hooks constrained in the pair of cap coupling grooves with the rotor coupling part of the base member arranged through the through hole to apply an external force to the rotor.
