[0034] This utility model provides a tip repair device, which includes three independently arranged repair cylinders. The three repair cylinders are used to perform different steps of tip repair, which facilitates the user's maintenance and replacement work.

[0035] Reference Figures 1 to 8 This embodiment provides a tip repair device, including a first repair cylinder 1, a second repair cylinder 2, and a third repair cylinder 3. The first repair cylinder 1, the second repair cylinder 2, and the third repair cylinder 3 are independent of each other. A first blade 11 is provided at one end of the first repair cylinder 1. The cutting edge of the first blade 11 faces the end of the first repair cylinder 1 and is perpendicular to the end of the first repair cylinder 1. A second blade 222 is provided on the second repair cylinder 2. The cutting edge of the second blade 222 faces the center of the second repair cylinder 2. A third blade 31 is provided at one end of the third repair cylinder 3. The third blade 31 is designed with an arc-shaped structure.

[0036] This embodiment provides a cue tip repair device, mainly used for repairing billiard cues. The first repair cylinder 1, the second repair cylinder 2, and the third repair cylinder 3 are all hollow cylindrical structures. The first repair cylinder 1 has an axially penetrating first insertion hole 10, the second repair cylinder 2 has an axially penetrating second insertion hole 20, and the third repair cylinder 3 has an axially penetrating third insertion hole 30. The billiard cue to be repaired can be inserted into the first insertion hole 10, the second insertion hole 20, and the third insertion hole 30 respectively to perform the corresponding repair steps.

[0037] The blade of the second blade 222 mentioned above faces the center of the second repair cylinder 2, meaning that the blade of the second blade 222 is located on one side of the second insertion hole 20 of the second repair cylinder 2. When the billiard cue is inserted into the second insertion hole 20, the second blade 222 can repair the edge of the cue tip.

[0038] Specifically, the first blade 11 is used to remove glue from the tip or the brass band, that is, to scrape off the remaining shavings and old glue residue on the tip or the brass band, so that the user can easily attach a new tip to the tip; the second blade 222 is used to repair the edge of the tip, so that the outer edge size of the tip matches the outer edge size of the tip, to ensure the direct transmission of power when hitting the ball, and improve the accuracy and control of the shot; the third blade 31 is used to shape the curvature of the tip, so that the club can be used for different hitting angles and directions.

[0039] Preferably, the cutting edge of the first blade 11 faces the end of the first repair cylinder 1 and is perpendicular to the end of the first repair cylinder 1. When repairing a cue stick, the end of the cue stick with the old tip cut off is inserted into the first repair cylinder 1, so that the tip of the cue stick abuts against the cutting edge of the first blade 11. Applying external force to rotate the first repair cylinder 1 can smooth the adhesive surface of the tip.

[0040] Preferably, the body of the first repair cylinder 1 is provided with a first polishing area 12, and a first sandpaper 121 is provided in the middle of the first polishing area 12.

[0041] Furthermore, the body of the third repair cylinder 3 is provided with a second polishing area 32, and a second sandpaper 321 is provided in the middle of the second polishing area 32.

[0042] Understandably, before attaching the cue tip to the ferrule, the contact surface of the tip needs to be sanded. Sanding removes any unevenness at the bottom of the new tip, ensuring a smooth contact surface between the tip and the ferrule, which helps the glue adhere better. By providing sanding areas on the first repair cylinder 1 and the second repair cylinder 2, users can sand the tip without needing to prepare additional sandpaper.

[0043] Preferably, the first polishing area 12 is a planar structure and the second polishing area 32 is an arc-shaped structure, which are respectively used to meet the planar polishing requirements and arc polishing requirements of the leather tip.

[0044] Preferably, the tip repair device has at least two blade sets 22, each blade set 22 including an integrally injection-molded blade holder 221 and a second blade 222. Specifically, different blade sets 22 have second blades 222 and blade holders 221 of different specifications, and the blade holder 221 can be detachably connected to the second repair cylinder 2.

[0045] In other embodiments, the second blade 222 and the blade holder 221 can be connected by screws, so that the second blade 222 and the blade holder 221 form a detachable connection, which makes it convenient for users to repair and replace the second blade 222 after the blade is worn.

[0046] It is important to note that existing billiard cues come in various styles, with differences in head size, length, weight, and diameter. Common tip repair devices on the market typically only include a single blade assembly 22, which is insufficient for repairing various cue models and limits their applicability. The tip repair device provided in this embodiment, however, utilizes multiple blade assemblies 22 with different specifications, making it suitable for repairing billiard cues of different sizes.

[0047] To facilitate identification, size labels can be affixed to the blade holder 221. Before use, check whether the label on the blade holder 221 is compatible with the billiard cue to be repaired. If the size of the blade assembly 22 is not compatible with the size of the billiard cue, remove the blade assembly 22 from the second repair cylinder 2 and replace it with a blade assembly 22 that is compatible with the billiard cue.

[0048] Preferably, the side of the second repair cylinder 2 is provided with a through hole 23, and the outer peripheral contour of the blade assembly 22 is adapted to the inner peripheral contour of the through hole 23. By applying external force to insert the blade assembly 22 into the through hole 23, the blade holder 221 in the blade assembly 22 will be interference-fitted with the side wall of the through hole 23, so that the blade assembly 22 is held on the second repair cylinder 2.

[0049] It should be noted that the through hole 23 is connected to the hollow structure inside the second repair cylinder 2. When repairing the tip of the billiard cue, the billiard cue is inserted into the second repair cylinder 2 along the hollow structure, and then the edge of the tip is repaired by the second blade 222 on the side.

[0050] Furthermore, the bottom wall of the through hole 23 is provided with a first platform 231 and a second platform 233. The first platform 231 and the second platform 233 are arranged adjacent to each other and form a first step 234. The blade holder 221 is provided with a first connecting part 224 and a second connecting part 225. The first connecting part 224 and the second connecting part 225 are arranged adjacent to each other and form a second step 226. The first step 234 and the second step 226 are adapted to each other.

[0051] Preferably, a locking block 232 is provided on the first platform 231, and a locking slot 223 is provided on the blade holder 221, with the locking block 232 and the locking slot 223 being compatible.

[0052] By setting the locking block 232, it can play a positioning and limiting role. During assembly, the blade holder 221 is inserted along the through hole 23 at the end away from the locking block 232 until the locking block 232 is inserted into the slot 223, which indicates that the blade assembly 22 has been assembled in place.

[0053] Preferably, the second repair cylinder 2 is further provided with a clamping structure 24, which includes a clamping part 241 and an adjusting part 242. The clamping part 241 is located on one side of the through hole 23, and the adjusting part 242 is located outside the second repair cylinder 2. The adjusting part 242 and the clamping part 241 are connected by a connecting post 243. An elastic element 244 is sleeved on the outer periphery of the connecting post 243. The elastic element 244 is located between the inner wall of the second repair cylinder 2 and the clamping part 241.

[0054] Specifically, the clamping part 241 is designed with an arc shape, and the blade holder 221 is also designed with an arc shape on the side facing the second insertion hole 20. The clamping part 241 and the blade holder 221 together form the second insertion hole 20 through which the billiard cue passes. By setting the clamping structure 24, the second insertion hole 20 can have different inner circumferential dimensions to suit the repair work of billiard cues of different sizes. The user applies external force to the adjusting part 242 so that the clamping part 241 abuts against the inner wall of the second repair cylinder 2, and then inserts the billiard cue into the second repair cylinder 2. After releasing the adjusting part 242, the elastic element 244 will generate an elastic restoring force, so that the clamping part 241 abuts against the surface of the billiard cue. Then, external force is applied to rotate the second repair cylinder 2, and the second blade 222 will act on the edge of the tip of the billiard cue to complete the repair work.

[0055] Preferably, there are two third blades 31, which are symmetrically arranged at one end of the third repair cylinder 3 with their blades facing downwards.

[0056] In existing tip repair tools, only one blade is usually provided to trim the tip into a curved shape. However, in this embodiment, two opposing curved blades are provided, which can repair opposite sides of the tip at the same time, improving the efficiency of tip repair. In addition, the opposing blades can make the tip repair more uniform, thereby increasing aesthetics and functionality.

[0057] Preferably, the first blade 11 is connected to the first repair cylinder 1 by a first screw 13, and the third blade 31 is connected to the third repair cylinder 3 by a second screw 33. The screws form a detachable connection between the blade and the repair cylinder, facilitating maintenance and replacement of the blade by the user.

[0058] It is understood that those skilled in the art can combine various implementation methods in the above embodiments under the guidance of the above examples to obtain technical solutions with multiple implementation methods.

[0059] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
