On the contrary, when the user tilts the monitor downward as necessary, the first turning rib 117b of the neck portion 110 and the separation preventing block 126b face each other, thereby preventing the neck portion 110 from being separated. The rotation angle of the neck portion 110 is maintained.

Next, when the first turning ribs 117a and 117b of the neck portion 110 are aligned with the release preventing blocks 126a and 126b, respectively, the neck portion 110 is clockwise 90 degrees. When the user tilts the monitor upward as needed under the angled rotation, the first pivoting rib 117a of the neck portion 110 guides while gently contacting the second pivoting rib 124a of the stand 120. The neck portion 110 is inclined smoothly in the desired direction. At this time, the separation of the neck portion 110 is prevented by the interaction between the first turning rib 117a and the second turning rib 124a and the rotation angle of the neck portion 110 is maintained.

On the other hand, if the user tilts the monitor downward as necessary, the first turning rib 117b of the neck part 110 is guided while gently contacting the second turning rib 124b of the stand 120 to be the neck part ( 110 is tilted smoothly in the desired direction. At this time, the separation of the neck portion 110 is prevented by the interaction of the first turning rib 117b and the second turning rib 124b and the rotation angle of the neck portion 110 is maintained.

As described above, in the monitor stand assembly according to the present invention, the shape and the coupling structure of the neck portion and the stand are omitted so that a coupling part such as a coupling screw required to join the neck portion and the stand in the conventional monitor stand assembly is unnecessary. By improving, the engagement between the neck portion and the stand is easy, and the manufacturing cost is reduced. In addition, since the monitor and the monitor stand assembly can be assembled regardless of the front and rear directions irrespective of the assembly direction, the assembly work is easy. That is, it can be assembled easily by rotating the neck part clockwise after matching the opening part of the neck part and the hinge structure direction of a stand, without the directionality of a neck part.
