[0018] As used herein, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive from other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0019] DETAILED DESCRIPTION OF THE INVENTION In order to enable those skilled in the art to have a better understanding of the technical solutions in the embodiments of the present invention, the following description will be made clearly and completely with reference to the accompanying drawings.

[0020] As shown in Figs. 1 to 4, this is an embodiment provided in the present invention.

[0021] According to this embodiment, a billiard cue is provided, which includes a rear cue 10 and a front cue 20, the rear cue 10 being detachably connected to the front cue 20, and the front cue 20 being configured as a replaceable part with different lengths, so that 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 an end cap 14, the first receiving hole 11 is disposed along the axial direction of the rear cue 10, and the depth of the first receiving hole 11 is greater than the combined length 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, making it easy to attach, detach, and replace, and the adjusting rod 13 is movably disposed inside the first receiving hole 11, so that the center of gravity of the rear cue 10 can be changed by changing the position of the adjusting rod 13 in the first mounting hole 112. The adjusting rod 13 may be connected to the first receiving hole 11 by an interference fit or a threaded fit to prevent the adjusting rod 13 from swinging back and forth within the first receiving hole 11 and affecting the impact when the billiard club is in use. If an interference fit is used, the adjusting rod 13 should be provided with an air vent in the center and a hook ring to facilitate pushing and pulling the adjusting rod 13 with a tool such as a stick or hook, or a drawstring directly attached to 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 the air vent is to facilitate balancing the air pressure inside and outside the first receiving hole 11 and allow the adjusting rod 13 to move normally within the first receiving hole 11. If a threaded fit is used, the outer end of the adjusting rod 13 should be provided with a line hole, a cross recess, or a hexagonal recess, and the thread of the adjusting rod 13 should be provided with an axial air vent groove so that the adjusting rod 13 can be rotated using a tool such as a screwdriver. The end cap 14 is connected to the rear end of the first accommodating hole 11, thereby preventing miscellaneous items from falling into the first accommodating hole 11 and allowing the rear end of the counterweight rod 12 to abut against it.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 rear cue stick 10 individually or together. When it is necessary to adjust the weight and center of gravity of the rear cue stick 10, if the weight of the counterweight rod 12 is heavy, the center of gravity of the rear cue stick 10 will be further rearward, and if the position of the adjusting rod 13 is closer to the inner end of the first receiving hole 11, the center of gravity of the rear cue stick 10 will be relatively forward. During use, to satisfy different hitting effects, the weight and center of gravity of the billiard cue stick can be changed as needed by selecting to adjust the data of the counterweight rod 12 or the data of the adjusting rod 13. If the weight and center of gravity of the counterweight rod 12 are closer to the inner end of the first receiving hole 11, the center of gravity of the rear cue stick 10 will be relatively forward. In addition, an NFC module 15 is attached inside the end cap 14 for connecting signals with external sensor devices, and it can be connected to electronic information devices such as mobile phones via the NFC module 15. Different identification information can be assigned to each billiard cue, and parameter information of the billiard cue itself can be marked, thereby improving the product added value and playability of the billiard cue.

[0022] Specifically, the first receiving hole 11 includes an adjustment hole 111 and a mounting hole 112, both of which are internally threaded. The counterweight rod 12 and the adjustment rod 13 are threadedly connected to the adjustment hole 111, with the adjustment rod 13 threaded into the adjustment hole 111 using a headless screw and the counterweight rod 12 threaded into the outer end of the adjustment hole 111 using a conventional screw. The end cap 14 is threadedly connected to the mounting hole 112 for easy attachment and detachment. The inner diameter of the mounting hole 112 is larger than that of the adjustment hole 111 to easily accommodate the screw head of the counterweight rod 12, and the length of the mounting hole 112 is shorter than that of the adjustment hole 111.

[0023] 4, a second receiving hole 121 having a depth greater than the length of the adjusting rod 13 is provided in the counterweight rod 12, and the adjusting rod 13 is movably provided in the second receiving hole 121. In this embodiment, the adjusting rod 13 does not have to be provided in the first receiving hole 11, but by setting the lengths of the counterweight rod 12 and the second receiving hole 121 to be longer, the movable range of the adjusting rod 13 is increased, and the effect of changing the center of gravity of the rear cue 10 is more pronounced. Of course, two adjusting rods 13 may be provided, one fitted inside the first receiving hole 11 and the other fitted inside the second receiving hole 121.

[0024] Specifically, a first connecting hole 16 is provided at the front end of the rear cue stick 10, and a second connecting hole 21 is provided at the rear end of the front cue stick 20. The first connecting hole 16 and the second connecting hole 21 are threadedly connected via a connecting tooth bar 30. The total depth of the first connecting hole 16 and the second connecting hole 21 is equal to or greater than the length of the connecting tooth bar 30, and the connecting tooth bar 30 can be replaced with a different length or weight to adjust the weight and center of gravity of the billiard cue. An optional washer 31 can be attached to the connecting tooth bar 30, and one or more washers 31 may be provided depending on the thickness. The washer 31 can be used not only as an exterior trim to enhance the aesthetic appearance of the connection between the front cue stick 20 and the rear cue stick 10, but also to adjust the connection depth between the connecting tooth bar 30 and the first connecting hole 16 and the second connecting hole 21, thereby allowing the overall length of the billiard cue to be adjusted without replacing the front cue stick 20. Furthermore, a first sleeve nut 161 is fixedly provided in the first connecting hole 16, and a second sleeve nut 211 is fixedly provided in the second connecting hole 21. Both ends of the connecting tooth bar 30 are threadedly connected to the first sleeve nut 161 and the second sleeve nut 211, respectively. The provided first sleeve nut 161 and second sleeve nut 211 can enhance the structural strength of the first connecting hole 16 and the second connecting hole 21, and can prevent wear on the first connecting hole 16 or the second connecting hole 21 and cracking of the ends of the front cue stick 20 or the rear cue stick 10 due to frequent rotation of the threads.

[0025] Specifically, the end cap 14 comprises a third sleeve nut 141 and an end plug 142, the NFC module 15 is provided within the third sleeve nut 141, the end plug 142 is threadedly connected to the third sleeve nut 141, and the third sleeve nut 141 is threadedly connected to the first accommodating hole 11.

[0026] Specifically, the counterweight rod 12 and the adjusting rod 13 are made of the same or different materials, including plastic steel, ABS, carbon fiber, and metal materials. For example, the counterweight rod 12 and the adjusting rod 13 are both made of carbon fiber material, or the counterweight rod 12 is made of plastic steel material and the adjusting rod 13 is made of metal material.

[0027] Specifically, the material of the front cue 20 and the rear cue 10 is any one of carbon fiber, glass fiber, and metal material.
