1 . A billiard cue, comprising: 
 a shaft having a chamber therein;    a bar detachably mounted in the chamber, and    a weight adjuster movably mounted on the bar and fixed at positions of the bar.    
   
   
       2 . The billiard cue as claimed in  claim 1 , wherein the bar has a thread thereon and the weight adjuster has a first weight device having a thread hole to be screwed onto the bar.  
   
   
       3 . The billiard cue as claimed in  claim 2 , wherein the first weight device of the weight adjuster has a cone end, a butt end and a cone slot at an end of the thread hole at the butt end.  
   
   
       4 . The billiard cue as claimed in  claim 2 , wherein the first weight device of the weight adjuster has an annular pad on a periphery thereof.  
   
   
       5 . The billiard cue as claimed in  claim 1 , wherein the bar has a thread thereon and the weight adjuster has two first weight devices and at least a second weight device, wherein each of the first weight devices have a thread hole to be screwed onto the bar and the second weight device had a through hole to be fitted onto the bar and rested between the first weight devices.  
   
   
       6 . The billiard cue as claimed in  claim 5 , wherein the second weight device of the weight adjuster has a cone end, a butt end and a cone slot at an end of the through hole at the butt end.  
   
   
       7 . The billiard cue as claimed in  claim 5 , wherein the second weight device of the weight adjuster has an annular pad on a periphery thereof.  
   
   
       8 . The billiard cue as claimed in  claim 1 , wherein the shaft has a thread hole at a bottom of the chamber and the bar has a thread thereon to be screwed into the thread hole.  
   
   
       9 . The billiard cue as claimed in  claim 1 , wherein the bar is provided with a stem at an end thereof wherein the stem has a plug portion to be inserted into the chamber and a handle left out of the chamber.
