Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to an aiming device for a billiard cue, and in particular to an aiming device that can provide a high precise aiming in billiards.

[0003] 2. The Prior Arts

[0004] Generally, when striking a cue ball, people use naked eyes to aim at the ball. Due to the inaccuracy of the viewing angle and the difficulty of long-distance aiming, the way of aiming at the ball by naked eyes is not precise enough. It can only help a little to adjust the striking strength and direction of the cue. Hence, ordinary people except for those skilled billiard players are hard to aim at the ball precisely by naked eyes.

[0005] Currently, aiming reference points are located at a periphery of a conventional billiard table. If these points are located at the other side of the table, it is inevitable to have a deviation of aiming by naked eyes. Later a laser light aiming device was produced, which could project a light point onto...
