Abstract (en)
Disclosed in the present invention is a pool cue with changeable center of gravity comprises a front end hand rack rod (1) and a rear end hand-held rod (2). A connecting rod (3) is connected with the end of the front end hand rack rod (1). A plurality of ring counterweight pieces (4) run through the connecting rod (3). Each ring counterweight piece (4) has the same external diameter and thickness. Every ring counterweight pieces (4) has the same external diameter such that they can be arrayed at random order. The ring counterweight pieces(4) are made of various materials with different density and different weight, such that the gravity center of the pool cue can be adjusted by arraying the ring counterweight pieces (4) even though the ring counterweight pieces (4) have the same quantity and the same total weight.
