Billiards is a leisure sport in which players strike red and white billiard balls on a billiard table with a cue stick, that is, stroke them to compete for their own scores. Particularly during the stroke, in order to accurately move the billiard ball to a desired point, it is important to control the hitting position of the billiard ball and the force applied to the hitting position, which requires a large amount of practice.

During the stroke, hold the front part of the cue table on the billiard table with one hand so that the cue table maintains a posture facing a predetermined direction at a predetermined height, and push the cue table with the other hand, at a predetermined hitting position of the billiard ball, a predetermined hitting force This will be applied to hit the billiard ball. At this time, if the hand holding the cue stand shakes or the height of the cue stand is too low or high, the billiard ball does not move in the desired direction.

With one hand, you need to practice gripping the cue table with the front end toward the hitting area of the billiard ball, and letting the force to move the billiard ball to the desired area is applied to the hitting area of the billiard ball. Eh, there is a need for a device to help you practice more easily. In particular, the cue stand-type cradle in the form of a general pedestal has resistance due to the frictional force of the pedestal when the trainer moves the stroke, so it is difficult to apply force to the hitting area of the billiard ball. It is also not easy to keep it facing the hitting area until the stroke is complete.

In addition, a billiard table is not provided in general homes, and even if you practice billiards using a table such as a desk or dining table, a billiard ball weighing about 200g to 210g and a radius of about 61mm to 66mm falls on the floor, There are problems such as accidents or noise due to bumps or bumps, so it is limited in the billiard practice area.
