CONSTITUTION: A vacuum suction device comprises a suction plate(10), a lower body(20), a lift plate(30), and an upper body(40). The suction plate is manufactured from a flexible material, and a space is formed on the central part of the suction plate in a disc shape. The lower body is installed on the upper part of the suction plate. The lift plate is installed on the upper part of the lower body and is coupled to the suction plate. The upper body is installed outside the lift plate and lifts the lift plate through rotation.
