Full Description:
FIELD OF THE INVENTION 
   The present invention relates to a monitor bracket, and more particularly to a wall mounting monitor bracket that firmly and easily adjusts a monitor to different angles by adjusting a movable arm means and a connection means. 
   BACKGROUND OF THE INVENTION 
   The commercial monitor bracket is generally composed of two parts including a base disposed on the table and an angle-adjustable movable arm coupled with the base, wherein a monitor is fixed on one end of the movable arm such that the monitor can be disposed stably and the monitor&#39;s angle is adjustable. 
   However, the drawbacks existing in angle adjustment and integral assembly of the conventional monitor bracket are listed as follows: 
   1. In the process of coupling a plug of a computer machine with the monitor, the monitor or the movable arm must be detached first since the elevational angle of the monitor is not adjustable, causing the inconvenience to the user. 
   2. An accidental fall of the bracket including the monitor fixed thereon from the table may be caused easily by shifting the bracket or impacting the bracket incautiously, so it is unsteady and not safe enough. 
   3. The adjustment of the movable arm is confined to specific angles so the adjustable angle is incomplete, causing the inconvenience to the user. 
   SUMMARY OF THE INVENTION 
   It is a main object of the present invention to provide a wall mounting monitor bracket for firmly and easily adjusting the monitor to different angles. 
   In order to achieve the above object, a wall mounting monitor bracket comprises a sliding base means, at least a movable arm means, and at least a connection means. The movable arm means is hung on the sliding base means via one end, and connected to the connection means via the other end. The other end of the connection means is attached to a first monitor. By adjusting the movable arm means and the connection means, the first monitor can be firmly and easily adjusted to different angles.
