[0029] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figure 1-4 The image shown is an embodiment provided by this utility model.

[0031] This utility model provides a billiard cue, including a rear cue 10 and a front cue 20. The rear cue 10 and the front cue 20 are detachably connected. The front cue 20 can be configured as a replaceable part of different lengths, and the length of the cue can be easily changed by replacing the front cue 20. Specifically, the rear cue 10 includes a first receiving hole 11, a counterweight rod 12, an adjusting rod 13, and a plug 14. The first receiving hole 11 is arranged along the axial direction of the rear cue 10, and the depth of the first receiving hole 11 is greater than the sum of the lengths of the adjusting rod 13 and the counterweight rod 12. The counterweight rod 12 is inserted into the rear end of the first receiving hole 11 for easy disassembly and replacement. The adjusting rod 13 is movably disposed in the first receiving hole 11. By changing the position of the adjusting rod 13 in the first mounting hole 112, the center of gravity of the rear cue 10 can be changed. It is understandable that the adjusting rod 13 can be connected to the first receiving hole 11 via an interference fit or a threaded fit to prevent the adjusting rod 13 from wobbling back and forth within the first receiving hole 11 when using the billiard cue, thus affecting the shot. If an interference fit is used, a vent hole and a hook ring need to be provided in the middle of the adjusting rod 13 to facilitate pushing and pulling the adjusting rod 13 with tools such as sticks or hooks, or a pull rope can be directly provided at the outer end of the adjusting rod 13 to facilitate removing the adjusting rod 13 from the first receiving hole 11. The purpose of providing a vent hole is to facilitate balancing the air pressure inside and outside the first receiving hole 11, so that the adjusting rod 13 can move normally within the first receiving hole 11. If a threaded fit is used, a slotted hole, a cross hole, or a hexagonal hole needs to be provided at the outer end of the adjusting rod 13, and an axial vent groove needs to be provided on the thread of the adjusting rod 13 to facilitate turning the adjusting rod 13 with tools such as screwdrivers. The plug 14 is connected to the rear end of the first receiving hole 11 to hold the rear end of the counterweight rod 12 in place, while preventing debris from falling into the first receiving hole 11. Both the counterweight rod 12 and the adjusting rod 13 can be replaced with different lengths and weights to adjust the weight and center of gravity of the cue stick 10 individually or together. When adjusting the weight or center of gravity of the cue stick 10, a heavier counterweight rod 12 will shift the center of gravity of the cue stick 10 further back, while a position closer to the inner end of the first receiving hole 11 will shift the center of gravity of the cue stick 10 relatively forward. During use, the weight and center of gravity of the cue stick can be changed by adjusting the counterweight rod 12 or the adjusting rod 13 as needed to achieve different shot effects. Furthermore, an NFC module 15 is installed inside the end cap 14 for connecting to external sensing devices. The NFC module 15 allows connection to mobile phones and other electronic devices, enabling each cue stick to be assigned different identification information and its own parameter information, thus increasing the added value and playability of the cue stick.

[0032] Specifically, the first receiving hole 11 includes an adjustment hole 111 and a mounting hole 112. Both the adjustment hole 111 and the mounting hole 112 are internally threaded holes. The counterweight rod 12 and the adjustment rod 13 are threaded to the adjustment hole 111 respectively. The adjustment rod 13 is screwed into the adjustment hole 111 using a headless screw. The counterweight rod 12 can be screwed to the outer end of the adjustment hole 111 using a conventional screw. The plug 14 is threaded to the mounting hole 112 for easy disassembly and assembly. It should be noted that the inner diameter of the mounting hole 112 is larger than the inner diameter of the adjustment hole 111 to accommodate the screw head of the counterweight rod 12. The length of the mounting hole 112 is smaller than the length of the adjustment hole 111.

[0033] In another embodiment, please refer to the appendix. Figure 4 As shown, a second receiving hole 121 is provided inside the counterweight rod 12. The depth of the second receiving hole 121 is greater than the length of the adjusting rod 13. The adjusting rod 13 is movably disposed within the second receiving hole 121. In this embodiment, the adjusting rod 13 may not be disposed within the first receiving hole 11, but the lengths of the counterweight rod 12 and the second receiving hole 121 need to be made longer to increase the range of motion of the adjusting rod 13, making its effect on changing the center of gravity of the rear rod 10 more obvious. Of course, it is also possible to choose to provide two adjusting rods 13, and install the two adjusting rods 13 in the first receiving hole 11 and the second receiving hole 121 respectively.

[0034] Specifically, the front end of the rear cue 10 is provided with a first connecting hole 16, and the rear end of the front cue 20 is provided with a second connecting hole 21. The first connecting hole 16 and the second connecting hole 21 are connected by a connecting rod 30. The sum of the depths of the first connecting hole 16 and the second connecting hole 21 is greater than or equal to the length of the connecting rod 30. The connecting rod 30 can be replaced with different lengths and weights to adjust the weight and center of gravity of the billiard cue. In addition, a washer 31 can be fitted onto the connecting rod 30. One or more washers 31 can be provided depending on the thickness. The washer 31 can be used as an aesthetic decoration to enhance the appearance of the connection between the front cue 20 and the rear cue 10, and can also be used to adjust the connection depth between the connecting rod 30 and the first connecting hole 16 and the second connecting hole 21, thereby adjusting the overall length of the billiard cue without replacing the front cue 20. Furthermore, a first sleeve nut 161 is fixedly installed in the first connecting hole 16, and a second sleeve nut 211 is fixedly installed in the second connecting hole 21. The two ends of the connecting rod 30 are threadedly connected to the first sleeve nut 161 and the second sleeve nut 211 respectively. The first sleeve nut 161 and the second sleeve nut 211 can enhance the structural strength of the first connecting hole 16 and the second connecting hole 21, and avoid frequent rotation of the threads causing wear of the first connecting hole 16 or the second connecting hole 21, or even causing the end of the front rod 20 or the rear rod 10 to crack.

[0035] Specifically, the plug 14 includes a third sleeve nut 141 and a tail plug 142. The NFC module 15 is disposed inside the third sleeve nut 141. The tail plug 142 is threadedly connected to the third sleeve nut 141. The third sleeve nut 141 is threadedly connected to the first receiving hole 11.

[0036] Specifically, the counterweight rod 12 and the adjusting rod 13 are made of the same or different materials such as plastic steel, ABS, carbon fiber, and metal. For example, both the counterweight rod 12 and the adjusting rod 13 are made of carbon fiber, or the counterweight rod 12 is made of plastic steel and the adjusting rod 13 is made of metal.

[0037] Specifically, the front bar 20 and the rear bar 10 are made of one of the following materials: carbon fiber, glass fiber, or metal.

[0038] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
