<p>A vacuum adsorbing 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 adsorption; an adsorption plate, which is coupled to the lower portion of the cover, for vacuum adsorbing to the flat surface; and a height adjustment member, which is arranged between the cover and the adsorption plate, for moving the adsorption 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 adsorbing device of the present invention enhances adsorption force so as to couple the vacuum adsorption device to the flat surface more solidly and for a longer time, enhances assembly between each of the elements for vacuum adsorption, and prevents unlocking due to outside shock by forming a double locking structure in the vacuum adsorption device.</p> |
