Description
BACKGROUND OF THE INVENTION

(1) Field of the Invention

The present invention relates to a monitor support device which allows the monitor to be pivoted in horizontal directions and can be supported in vertical directions.

(2) Description of the Prior Arts

In a modern office, computers are used for the members in the office and each member is equipped with at least one monitor which is connected with a computer so as to form a office network. Each monitor is connected to the desk by a support device which generally includes a base with a post connected thereon and the monitor is pivotably connected to the post. The monitor can be adjusted in horizontal directions to meet the user's needs. However, an inherent shortcoming for the conventional monitor support device is that the monitor is so heavy so that the support device cannot well hold it in the direction directions and the monitor tends to pivot downward due to its weight.
