[0024] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7, the present utility model provides a technical solution: a billiard cue, including a first cue 1, a second cue 11, a third cue 12, a tip 13, a splicing component for connecting the first cue 1, the second cue 11 and the third cue 12, and a connecting component for quickly replacing the tip 13. The splicing component includes splicing grooves 21 respectively opened on one side of the second cue 11 and the third cue 12, an annular groove 22 opened on the inner wall of the splicing groove 21, through openings 23 respectively opened on both sides inside the annular groove 22, a first threaded groove 24 opened on one side inside the splicing groove 21, a counterweight screw 25 connected to the first threaded groove 24, splicing blocks 26 respectively connected to one side of the first cue 1 and the second cue 11, positioning blocks 27 respectively connected to both sides of the splicing blocks 26, a plurality of grooves 28 arranged in a circumferential pattern on one side inside the annular groove 22, ejector rods 29 connected to the grooves 28, a first spring 30 connected to one end of the ejector rod 29, an annular plate 31 connected to the other end of the ejector rod 29, and a snap component for improving splicing stability. The ejector rod 29 is slidably connected to the groove 28, the counterweight screw 25 is screwed into the first threaded groove 24, the splicing blocks 26 at one ends of the first cue 1 and the second cue 11 can be inserted into the splicing groove 21, the positioning blocks 27 pass through the through openings 23 and enter the annular groove 22, and push the annular plate 31 to move. The movement of the annular plate 31 can squeeze the first spring 30 to deform it. By rotating the first cue 1 and the second cue 11, the positioning blocks 27 can be turned into the annular groove 22. Under the thrust generated by the deformation of the first spring 30, the positioning blocks 27 are in close contact with the inner wall of the annular groove 22, and the first cue 1, the second cue 11 and the third cue 12 can be spliced and fixed. The operation is relatively convenient, and it can be quickly separated, which is convenient for transportation and carrying. Multiple or single counterweight screws 25 can be screwed into the first threaded groove 24 according to needs to change the center of gravity, which is convenient for different people to use. The snap component includes a placement groove 51 opened on one side of the positioning block 27, a push rod 52 connected to the placement groove 51, a second spring 53 connected to one end of the push rod 52, a hemispherical portion 54 connected to the other end of the push rod 52, and hemispherical grooves 55 opened on both sides inside the annular groove 22. The hemispherical portion 54 is inserted into the hemispherical groove 55, the push rod 52 is slidably connected to the placement groove 51, and the hemispherical portion 54 can drive the push rod 52 to slide in the placement groove 51 under the extrusion of the annular groove 22. The movement of the push rod 52 squeezes the second spring 53 to deform it. When the hemispherical portion 54 contacts the hemispherical groove 55, the reset of the second spring 53 can make the hemispherical portion 54 snap into the hemispherical groove 55, which can perform secondary limit fixation on the positioning block 27 to prevent the positioning block 27 from rotating, and thus can improve the splicing stability. A protection groove 61 is opened on one side of the push rod 52, and a protection rod 62 is fixedly connected to the inner wall of the placement groove 51. The protection rod 62 is slidably connected to the protection groove 61. The protection rod 62 can slide in the protection groove 61, which can prevent the push rod 52 from rotating, and thus can prevent the second spring 53 from rotating and being damaged. A first elastic sheet 71 is sleeved outside the ejector rod 29.One side of the first elastic piece 71 abuts against the second elastic piece 72. One side of the first elastic piece 71 is fixedly connected to the annular plate 31. One side of the second elastic piece 72 is fixedly connected to the inner wall of the annular groove 22. When the annular plate 31 moves, it can push the first elastic piece 71 to move. The first elastic piece 71 and the second elastic piece 72 abut against each other, so that the first elastic piece 71 and the second elastic piece 72 can be deformed, which can further increase the extrusion force on the positioning block 27 and further improve the splicing stability. One end of the first cue 1 is fixedly connected with a buffer pad 81, and the outer side of the first cue 1 is fixedly connected with an anti-slip pad 82. When the cue is placed vertically, the buffer pad 81 can play a buffering and protecting role, and the anti-slip pad 82 can increase the friction between the cue and the user, facilitating the user to play the ball.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 , the connecting component includes a second threaded groove 41 opened at one end of the third cue 12, a fixing screw 42 fixedly connected to one end of the tip 13, and a limiting ring 43 fixedly connected to the outer side of the fixing screw 42. The fixing screw 42 is screwed into the second threaded groove 41. The fixing screw 42 on one side of the tip 13 can be screwed into the second threaded groove 41, so that the tip 13 and the third cue 12 can be quickly connected and fixed. Thus, when the tip 13 is damaged, the tip 13 can be quickly replaced. A plurality of protrusions 431 arranged in a circular pattern are fixedly connected to the outer side of the limiting ring 43. Both sides of the protrusion 431 are arc-shaped. The protrusion 431 can facilitate the user to drive the limiting ring 43 to rotate, and thus can facilitate driving the tip 13 to rotate, which is convenient for the installation and replacement of the tip 13.

[0026] Working principle: During operation, first align the splicing block 26 at one end of the second cue 11 with the splicing groove 21 at one end of the third cue 12, and then insert the splicing block 26 into the splicing groove 21. The positioning block 27 enters the annular groove 22 through the through port 23, contacts the annular plate 31, and pushes the annular plate 31 to move. The movement of the annular plate 31 can drive the ejector rod 29 to move, and the movement of the ejector rod 29 can cause the first spring 30 to deform. At the same time, the annular plate 31 can push the first elastic piece 71 to move, and the first elastic piece 71 abuts against the second elastic piece 72, so the first elastic piece 71 and the second elastic piece 72 will also deform. At this time, the second cue 11 can be rotated by 90 degrees to make the positioning block 27 turn into the annular groove 22. At this time, the thrust generated by the deformation of the first elastic piece 71, the second elastic piece 72, and the first spring 30 can make the positioning block 27 closely contact the inner wall of the annular groove 22, preventing it from rotating and separating without external force. Under the extrusion of the inner wall of the annular groove 22, the hemispherical part 54 can drive the push rod 52 to move in the placement groove 51, and the movement of the push rod 52 can squeeze the second spring 53 to deform it. When the hemispherical part 54 contacts the hemispherical groove 55, the second spring 53 can reset and push the hemispherical part 54 into the hemispherical groove 55, which can perform secondary fixation on the positioning block 27, thereby improving the splicing stability. Then align the splicing block 26 at one end of the first cue 1 with the splicing groove 21 at one end of the second cue 11, and then repeat the above steps to splice and fix the first cue 1, the second cue 11, and the third cue 12 for convenient use. Then screw the fixing screw 42 on one side of the leather tip 13 into the second thread groove 41 until it can no longer be screwed. Then the cue can be used. When the leather tip 13 is damaged, the leather tip 13 can be quickly unscrewed and replaced with a new one using the protrusion 431. When transportation is required, the first cue 1 and the second cue 11 can be rotated 90 degrees in the reverse direction respectively to make the hemispherical part 54 disengage from the hemispherical groove 55. At this time, the positioning block 27 turns to the through port 23. At this time, the first spring 30, the first elastic piece 71, and the second elastic piece 72 reset, and can push the first cue 1 and the second cue 11 out to improve the separation efficiency. The above is the entire working process of the device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0027] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
