[0027] The present application will be described below with reference to the accompanying drawings, which illustrate several embodiments of the present application. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and fully illustrate the scope of protection of the present application to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide many additional embodiments.

[0028] The tip of a pool cue provides friction when hitting the ball, helping to control rotation and force, while also providing shock absorption and protection for the shaft, improving the feel and enhancing the controllability of the ball. The tip is connected to the shaft via a horn and is often replaced due to wear, hardening, cracking, or for improved feel, and requires trimming after replacement. Chinese utility model patent CN220558521U discloses a multifunctional pool cue tip repairer that includes cutting, turning, and polishing functional areas. However, existing devices are bulky, inconvenient to carry, and have poor safety features. Some sharp parts are exposed, posing a safety hazard.

[0029] The embodiment of the present application provides a foldable leather tip repairer. Please refer to Figures 3 to 5 , Figures 3 to 5The structure of the repair device is shown from various angles and positions, including a repair blade 100 and a folding plate 200. The folding plate 200 is rotatably connected to the repair blade 100 via a shaft. A cutting hole 14 is provided through the repair blade 100. A second blade body 21 is positioned on the folding plate 200 at a corresponding position, with its blade facing the folding and shearing direction of the folding plate 200. The folding and shearing direction can be understood as the direction of the side of the folding plate 200 that first contacts the repair blade 100 when the folding plate 200 is folded into the repair blade 100. When the leather tip connected to the horn is inserted into the cutting hole 14 and the folding plate 200 is rotated toward the repair blade 100, the second blade body 21 cuts the leather tip, separating the old leather tip from the horn.

[0030] Furthermore, the repair knife 100 is provided with a receiving groove 20 that matches the folding plate 200, which can completely receive the folding plate 200 in the repair knife 100, thereby preventing the blade of the second blade body 21 from being exposed and reducing the size of the repairer.

[0031] Specifically, to further reduce the overall thickness of the repair tool, an arcuate slot 15 is designed on at least one side of the cutting hole 14. The fasteners used to secure the second blade body 21 and the folding plate 200 mate with the slot 15. When the folding plate 200 rotates around the repair tool 100, the fasteners slide within the slot 15, so that the fasteners protruding from the folding plate 200 are received by the slot 15. The two cooperate and constrain each other, making the rotation more stable.

[0032] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The structure of a billiard cue tip trimmer 100 is shown from different angles. The trimmer 100 comprises a first cavity 10, a second cavity 11, and a first blade 13. The first and second cavities 10 and 11 are interlaced and connected, with both cavities extending linearly inward from the surface of the trimmer 100. A notch 12 runs through the inner wall of the second cavity 11 along its central axis. The blade of the first blade 13 is located in this notch 12 and faces the opening of the first cavity 10.

[0033] Furthermore, the first cavity 10 and the second cavity 11 are both semi-cylindrical cavities.

[0034] Preferably, the first cavity 10 and the second cavity 11 are staggered at a 90-degree angle to reduce the length of the trimming knife 100. The opening direction of the first cavity 10 is opposite to the opening direction of the second cavity 11 to reduce the overall thickness of the trimming knife 100.

[0035] In the prior art, the first cavity 10 and the second cavity 11 are typically complete cylindrical or conical cavities on the body of the cutting tool 100, and both exist independently. However, in actual use, only half of the cavity is used to constrain the rotation of the front end of the billiard cue stick, ensuring that the tip of the cue stick maintains contact with the blade of the first blade body 13.

[0036] Specifically, the end of the first cavity 10 communicates with the end of the second cavity 11, thereby reducing the overall length of the trimming knife 100. A stopper surface 112 is provided at the end of the second cavity 11 to prevent the tip of the cue stick from excessively extending into the second cavity 11 and inserting into the first cavity 10 without compromising the integrity of the first cavity 10. Without this stopper surface 112, the tip of the cue stick could be inserted into the first cavity 10, causing the tip to scrape the edge of the cue stick at the junction of the first and second cavities 10, 11, resulting in damage.

[0037] The trimming knife 100 also includes a flat grinding disc 16, a glue removal grinding disc 17, a curved grinding disc 18 and a spherical cap grinding disc 19, wherein:

[0038] The flat grinding disc 16 is a large-area, flat-surfaced grinding disc or grinding block used for grinding. The upper surface of the flat grinding disc 16 is flush with the surface of the trimming knife 100 and can grind the corners of metal or plastic materials.

[0039] The adhesive removal grinding disc 17 is evenly arranged at the bottom of the cylindrical groove on the surface of the trimming knife 100;

[0040] The surface of the arc-shaped grinding disc 18 is a concave arc-shaped curved surface, with both end surfaces and the top surface being open, and the top edge of the arc-shaped grinding disc 18 is flush with the surface of the trimming knife 100;

[0041] The spherical crown grinding disc 19 is in the shape of a spherical crown and is placed in a hemispherical groove on the surface of the repairing knife 100. The plurality of spherical crown grinding discs 19 have different sizes to adapt to different specifications of golf club tips.

[0042] The folding plate 200 further includes a needle 22 and a measuring arc surface 23, wherein:

[0043] The needles 22 are needle-shaped and evenly arranged, with their tips facing the folding and shearing direction of the folding plate 200. When the folding plate 200 is stored in the storage slot 20 of the trimmer 100, the needles 22 are oriented toward the sidewalls of the storage slot 20, preventing the needles 22 from being exposed and causing accidental injuries.

[0044] The measuring arc surface 23 is provided on the outer edge of the folding plate 200 and has a plurality of measuring arc surfaces 23 with different arc angles to adapt to golf club tips of different specifications.

[0045] The storage slot 20 of the repairing razor 100 is provided with a magnetic component A. When the foldable skin tip repairer is folded, a magnetic component B is provided on the folding plate 200 at a position corresponding to the magnetic component A to ensure the stability of the folded state. The magnetic component A can be a ferrous metal nail, and the magnetic component B is a magnet.

[0046] Here’s how to use it:

[0047] 1. Remove the folding plate 200 from the trimming knife 100 and insert the tip of the pool cue into the cutting hole 14 of the trimming knife 100. When the folding plate 200 is rotated back to the side of the trimming knife 100, the second blade 21 will cut the tip from the front corner of the pool cue. If there is any glue or old tip left on the tip, use the flat grinding disc 16 to remove the residue and make the tip end smooth and clean.

[0048] 2. Insert the front end of the cue stick into the first cavity 10 and rotate the cue stick along the first support surface 101 to allow the first cutter body 13 to smooth the front corner end surface. Alternatively, press the front corner end surface onto the adhesive removal grinding disc 17 and rub the cue stick with both hands to quickly remove a large amount of residual adhesive.

[0049] 3. Take out the new leather head, polish its bonding surface with a flat grinding disc 16, and then bond the trimmed new leather head to the front corner end face.

[0050] 4. After gluing the new tip, insert the pool cue into the second cavity 11 to trim the side of the tip. Place the side of the tip against the second support surface 111 and rotate it, allowing the first blade 13 to turn the side of the tip. The stopper surface 112 prevents the tip from being over-inserted into the first cavity 10. Adjust the tip's top surface to maintain a 45-90 degree inclination with the second support surface 111. Rotate the cue to allow the first blade 13 to turn the tip's top surface. Then, quickly slide the curved grinding disc 18 across the tip's top surface, creating a preliminary arc.

[0051] 5. Insert the tip into the crown grinding disc 19 and rotate the cue to fine-tune the tip's arc. Use a finer-grit flat grinding disc 16 to remove burrs from the tip. Compare and measure the curvature of the curved surface 23 to confirm that the tip is properly trimmed.

[0052] 6. Finally, use the needle 22 to strike the surface of the leather head to increase its friction and improve its powder absorption performance.
