Billiards equipment 1. The billiard table is shaped like a rectangular conference table, so billiards is also called billiards. The length-width ratio of the inner frame of the billiard table should be 2: 1, and hardwood is generally used, especially in the small state around the table, such as teak, oak and willow. To make the frame elastic and impact-resistant, triangular rubber edges are arranged on the wooden frame to increase the elasticity of the frame. The table top is paved with 3-4 stone slabs with smooth surface. After leveling by the installation master, the joints are tight and smooth, and the slate is covered with a layer of green tablecloth to increase the friction of the countertop. Tables are divided into bottom table edge, top table edge, left table edge and right table edge. Ball placement point: the point from the top platform edge to the quarter of the bottom platform edge, which intersects with the longitudinal center line, and the target ball is placed at this point. Inner area: Draw a horizontal line (dividing line) on the desktop one-fifth from the edge of the bottom table to divide the desktop into two parts, and the area one-fifth from the edge of the bottom table is called the inner area. Outer zone: Four fifths of the area from the dividing line to the edge of the dome is called the outer zone. Bottom bag: the ball bag at the edge of the bottom table is called the bottom bag, the left side is called the left bottom bag, and the right side is called the right bottom bag. Middle bag: the ball bag located in the half of the left table is called the left middle bag, and the ball bag located on the right side is called the right middle bag. Top bag: The two ball bags located at the edge of the top platform are the left top bag and the right top bag respectively. Tee-off area: Take one-sixth of the width of the table as the radius, draw a semicircle inward at the midpoint of the dividing line, and the semicircle formed is the tee-off area. 2. Billiards In the early days, billiards were made of fine ivory. Most billiards used now are made of high-quality plastic. Plastic balls have good elasticity and toughness, smooth surface, uniform texture, accurate center of gravity and roundness, and are not easy to deform. 3. Clubs and clubs are made of high quality wood. The shaft is round, with a length of 1.3m- 1.5m, which can be long or short. Generally, the length should be shoulder-length, and the center of gravity should be correct, which should be in a quarter or a third of the tail of the club, and the head diameter is about 9- 12mm. The front end of the club is a head made of metal or plastic, and a leather head (also known as a gun head) is stuck in front of the head. The leather head is made of high quality leather, which directly affects hitting the ball. The leather head is elastic, which can control the impact force when hitting the ball and prevent slipping. In order to prevent slipping after hitting the ball three or four times, the leather should be coated with shell powder. The leather head should be trimmed and polished frequently to make it in the best condition. 4. Club rack, shell powder, tripod, etc. Although these devices and electrical appliances may seem unremarkable, they are also essential. 5.
