[0002] As is known to all, the existing billiard cue is a rod body that gradually becomes thicker from the front end to the rear end, and the rear end is the grip end. The weight of each billiard cue produced by the manufacturer is relatively fixed, and for different users, the weight of the billiard cue that is suitable or accustomed to is different. In order to meet the actual use needs, the existing billiard cue has added a weighted structure, such as a weighted billiard cue described in Chinese Patent No.: "201220609822.6", the specific structure of the weighted billiard cue is: it is composed of a rear section rod, a lower ring, a middle wheel, an upper ring, a front section rod, a first angle, a leather head, and a rubber seat bottom. The outer side of the rear section rod is provided with a section of non-slip grip, the bottom of the rear section rod is fixedly provided with a rubber seat bottom, the top surface of the rear section rod is fixedly provided with a lower ring, the bottom surface of the middle wheel is fixed on the lower ring, the top surface of the middle wheel is fixedly connected with the upper ring, the bottom end of the front section rod is fixed on the upper ring, the top of the front section rod is fixedly connected with the first angle, and the top of the first angle is fixedly provided with a leather head. The lower ring and the upper ring play a role in buffering the impact force and preventing the front and rear sections from cracking when hitting the billiard ball. The middle wheel is used to connect the rear section and the front section. The front corner is made of metal or plastic. The rubber base has a certain weight, which can increase the weight of the entire rod.

[0003] In the above structure, the weight is added by the rubber base, which cannot be adjusted, and the applicable range of users is small; and the rubber base is located at the tail of the billiard cue, and only the tail of the billiard cue is weighted, resulting in uneven weight distribution of the billiard cue, which is easy to cause the head of the billiard cue to tilt forward when the billiard cue hits the ball; at the same time, the existing billiard cues are mostly made of wood, which is easily corroded and damaged by wind and rain, resulting in cracks, causing the billiard cue to be damaged and having a short service life.

The rear rod 2 includes an inner layer 23 and an outer layer 24. The inner layer 23 is made of wood, and the outer layer 24 is made of a carbon fiber tube. The carbon fiber tube is sleeved outside the wood to protect the wood from moisture and improve its service life. The second accommodating cavity 21 is located in the inner layer 23.

[0025] In the above technical scheme: a connecting block 4 is also threadedly installed in the first accommodating cavity 11, and the connecting block 4 is located below the first weight block 12, and a first threaded section 43 is provided in the connecting block 4. A middle wheel 3 is provided at the top of the rear rod 2, and a connecting screw 5 is threadedly penetrated in the middle wheel 3. A second threaded section is provided at the top of the rear rod 2. The two ends of the connecting screw 5 expose the middle wheel 3 and are respectively threadedly installed in the first threaded section 43 and the second threaded section, so as to realize the connection between the connecting block 4, the middle wheel 3 and the rear rod 2, thereby completing the connection between the front rod 1 and the rear rod 2. After installation, there is a gap between the end of the connecting screw 5 and the first weight block 12, which prevents the connecting screw 5 from hitting the first weight block 12 when the billiard cue is used, making noise and causing the first weight block 12 to be loosened, thereby improving the installation stability of the first weight block 12; and whether the installation of the first weight block 12 is loose can be judged by whether there is a sound when the connecting screw 5 hits the first weight block 12, so that the first weight block 12 can be tightened again.
