Description

Background technique

The billiard cue tip (also known as the gun tip) is glued to the front end of the billiard cue and is generally made of high-quality leather. Its quality directly affects the shot. Due to the appropriate elasticity and friction of the skin, it can control the impact force when hitting the ball and the rotation of the ball in motion (the middle and high-segment rod method is commonly used).

However, the existing skins are all convex spherical structures. When hitting the ball, no matter which hitting point is hit (refer to Figure 1), the contact with the billiard ball surface is point contact. Therefore, the more the hitting point is, the more you hit the ball. The stronger the ball, the easier it is to produce the phenomenon of sliding bars. Therefore, after hitting the ball three or four times in normal times, in order to prevent slippage, shell powder will be rubbed on the skin. Some people advocate that every shot must be rubbed, especially after hitting the ball harder or hitting the ball. However, it is still difficult to avoid the phenomenon of sliding bars.
