A vacuum suction device of the present invention comprises: a cover which is rotatably mounted on the upper portion so as to couple to a flat surface by means of vacuum suction; an suction plate, which is coupled to the lower portion of the cover, for vacuum suction to the flat surface; and a height adjustment member, which is arranged between the cover and the suction plate, for moving the suction plate back and forth according to the rotation of the cover; wherein a plurality of fixing pieces are formed on the upper surface of the inside of the cover, a plurality of elastic stoppers are coupled to the inside of the height adjustment member, so as to be movable by sliding when each of the fixing pieces is in contact, and for fixing the cover by each of the fixing pieces being hooked to the end portion of the cover so as to prevent reverse rotation. The vacuum suction device of the present invention enhances suction force so as to couple the vacuum suction device to the flat surface more solidly and for a longer time, enhances assembly between each of the elements for vacuum suction, and prevents unlocking due to outside shock by forming a double locking structure in the vacuum adsorption device.

1. A vacuum suction device comprising: a cover which is rotatable mounted on an upper portion of a height adjustment member so as to be coupled to a flat surface by vacuum suction:a suction plate which is coupled to a lower portion of the cover to be sucked by vacuum to the flat surface; andwherein the height adjustment member is arranged between the cover and the suction plate to move the suction plate upwards and downwards according to the rotation of the cover,wherein a plurality of fixing pieces are formed in a top surface of inside the cover, and a plurality of elastic stoppers having a certain elastic force are coupled to inside the height adjustment member in order for the each of the fixing pieces to move by sliding with the fixing piece contacting the elastic stopper and in order for the each of the fixing pieces to be hung on an end portion to fix the cover so as to prevent a backward rotation of the cover from occurring,wherein an insert hole formed in an upper portion of the cover into which one end of a hanging member is capable of being inserted into the insert hole, a plurality of rotation protrusion parts including a hook are formed in an inner surface of the cover and project into the insert hole, to be bent toward the insert hole, are radially formed to protrude, and a plurality of stop protrusion parts are formed to protrude in an inner circumference of the cover. 2. The vacuum suction device of claim 1. wherein each of the fixing pieces of the cover is bent to be formed into a ‘V’ shape, and a bent outer surface of each of the fixing pieces is formed into a round shape. 3. The vacuum suction device of claim 1, wherein one coupling surface or a plurality of coupling surfaces are formed in other side of the each of the elastic stoppers, a bent surface is formed in one side of the each of the elastic stoppers in order for the each of the fixing pieces to be hung on the bent surface to be fixed, and a curved surface, which the each of the fixing pieces contact to slide, is formed to be curved at a certain angle between the one side and the other side of the each of the elastic stoppers, the one side of the each of the elastic stoppers being a free end. 4. The vacuum suction device of claim 1, wherein each of the elastic stoppers are coupled to an inside the height adjustment member, and the each of the fixing pieces of the cover are hung, on end portions of each of the elastic stoppers to temporarily fix the cover when the fixing pieces of the cover is moving by sliding with the each of the fixing pieces contacting the each of the elastic stoppers. 5. The vacuum suction device of claim , wherein a bottom plate including a plurality of coupling holes are formed in a lower portion of the height adjustment member, and a side plate is formed on a top surface outside the bottom plate 21 the side plate comprising a plurality of stoppers which are formed to contact each stop protrusion part of the cover in order to protrude in order for the cover to rotate within a certain range, a inclined surface which is formed between the each of the stoppers and which is inclined at a certain angle in order for a bottom surface of the each of the stop protrusion parts to contact the inclined surface and to move by sliding, and a fixing groove part which is formed in one end portion of the each of the inclined surface and to which the each of the stop protrusion parts is temporarily fixed. 6. The vacuum suction device of claim 1, wherein a center shaft having a coupling groove, into which one side of a hanging member is capable of being inserted into the couplinggroove to be coupled, is formed in a top surface of a center part of the suction plate in order for the suction plate to be coupled to a lower portion of the cover, a stop groove part, into which a hook of the each of a rotation protrusion part is inserted to be coupled, is formed in an outer circumference of the center shaft, and a plurality of coupling protrusions, which are respectively inserted into a corresponding plurality of coupling holes, are formed in the suction plate.
