[0017] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0018] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0019] Embodiment 1

[0020] like Figure 1 and Figure 2 As shown, the specific embodiment of the utility model provides a ejection type billiard cue, which can automatically fire billiard balls, and specifically includes a billiard cue body 100 and an ejection rod 200; the billiard cue body 100 is provided with a mounting channel 110 that passes through the front end of the billiard cue body 100, and the outer surface of the billiard cue body 100 is provided with a locking groove 120 that passes through the mounting channel 110, and the opening of the locking groove 120 is movably installed with a trigger button 130; the ejection rod 200 is slidably installed in the mounting channel 110, and the ejection rod 200 is slidably installed in the mounting channel 110. 0 is provided with elastic locking protrusions 210 evenly spaced along its length, the locking protrusions 210 can be inserted into the locking groove 120, and the locking protrusions 210 are pressed out of the locking groove 120 when the trigger button 130 is pressed; an elastic mechanism is provided in the mounting channel 110, and when the ejection rod 200 slides toward the rear end of the billiard cue body 100, the elastic mechanism can accumulate elastic force and the ejection rod 200 can be ejected from the front end of the billiard cue body 100 after the locking protrusions 210 exit the locking groove 120.

[0021] like Figure 1 and Figure 2 As shown, through the above arrangement, the ejection type billiard cue in this embodiment is a combination of a billiard cue body 100 and an ejection rod 200, that is, the ejection rod 200 is slidably mounted on the front section of the billiard cue body 100, and the ejection rod 200 can slide in the mounting channel 110 and can slide out of the front end of the billiard cue body 100; when the billiard cue is in use, the ejection rod 200 is slid toward the rear end of the billiard cue body 100 according to the ejection requirement, and when it slides to a suitable position, the elastic locking protrusion 210 can be snapped into the locking groove 120 , since the elastic mechanism can accumulate elastic force when the ejection rod 200 slides backward; therefore, when firing a billiard ball, the trigger button 130 is pressed to make the locking protrusion 210 exit the locking groove 120, and the elastic force accumulated by the elastic mechanism can eject the ejection rod 200 from the front end of the billiard cue body 100 to realize the billiard firing operation. When performing a second firing, the ejection rod 200 is slid successively to make the locking protrusion 210 again engage in the locking groove 120. The use of an automatically firing billiard cue can enrich the competitive interest of billiard sports.

[0022] Embodiment 2

[0023] like Figure 1 As shown, this embodiment provides an elastic mechanism for firing the ejection rod 200, specifically comprising a compression spring 300 located at the rear end of the ejection rod 200 corresponding to the mounting channel 110, one end of the compression spring 300 being fixed to the bottom of the mounting channel 110, and the other end being connected to the rear end of the ejection rod 200. In this way, the use of the compression spring 300 can make the ejection rod 200 accumulate elastic force when moving toward the rear end of the cue stick body 100, and provide rebound according to the compression amount of the compression spring 300; its structure is simple and easy to operate.

[0024] like Figure 2 As shown, another elastic mechanism provided in this embodiment includes an elastic band 400 with elasticity, one end of which is connected to the rear end of the ejection rod 200, and the other end is fixed to the front end of the installation channel of the billiard cue body 100. In this way, since the elastic band 400 abuts against the rear end of the ejection rod 200, when the ejection rod 200 moves toward the rear end of the billiard cue body 100, the elastic band 400 is stretched to generate elastic force, and the ejection rod 200 is ejected from the front end of the billiard cue body 100 under the elastic force of the elastic band 400 to fire the billiard ball; in this embodiment, a fixing ring 500 is provided in the installation channel of the billiard cue body 100, and a fixing groove for fixing the elastic band 400 is provided on the fixing ring 500, and a fixing buckle 600 is clamped at the opening of the fixing groove. In this way, the elastic band 400 can be clamped into the fixing groove, and the elastic band 400 is fixed by the fixing buckle 600 to ensure installation stability.

[0025] In order to improve the stability of the ejection rod during the ejection process after firing, a shock absorbing ring 700 is fixed on the ejection rod in the installation channel of the billiard cue body 100. The shock absorbing ring 700 plays a shock absorbing role. By being loosely fastened on the ejection rod, the rear end of the ejection rod is limited, which is beneficial to improving the stability of the billiard ball during firing, and at the same time, it can prevent the ejection rod 200 from being separated from the billiard cue body 100 when it is ejected.

[0026] like Figure 1 and Figure 2 As shown, in order to prevent the ejection rod from shaking during the firing and ejecting process and to improve its ejection stability, a limiting slide is provided along the length of the inner wall of the installation channel of the billiard cue body in this embodiment, and the limiting slide is slidably matched with the locking protrusion.

[0027] like Figure 1 and Figure 2 As shown, in this embodiment, a detachable leather head 800 is further provided at the front end of the ejection rod 200. The detachable leather head 800 is provided to facilitate disassembly, assembly and replacement, and is convenient for adjustment and use by different groups of people.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
