[0062] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0063] See Figures 1 to 3 In Specific Embodiment 1, this Specific Embodiment 1 provides a knife sharpening bracket. The knife sharpening bracket 5 is provided with an opening groove 5-1 for installing a sharpening rod 8-1. The surface of the sharpening rod 8-1 corresponding to the opening part 5-1-1 of the opening groove 5-1 is a sharpening surface 8-1-1.

[0064] After installing the sharpening rod 8-1 in the opening groove 5-1 of the knife sharpening bracket 5, the grinding of the tool can be achieved. Different grit sharpening rods 8-1 can be replaced in the opening groove 5-1 by oneself, so that different uses such as rough grinding and fine grinding can be realized, meeting various knife sharpening requirements, and enabling the knife sharpener equipped with this knife sharpening bracket 5 to have multiple grinding functions (such as rough grinding, fine grinding, polishing, etc.).

[0065] The tool is ground on the sharpening surface 8-1-1. The sharpening rod 8-1 located in the opening groove 5-1 can also be rotated after unscrewing the third knob 5-3, and the sharpening rod 8-1 is rotated so that different positions on the outer surface of the sharpening rod 8-1 have the opportunity to correspond to the opening part 5-1-1 of the opening groove 5-1, and all can be used to grind the tool, making the best use of the outer surface of the sharpening rod 8-1 to the greatest extent, fully ensuring the working efficiency of the sharpening rod 8-1, effectively improving the utilization rate of the rod body of the sharpening rod 8-1, and ensuring that the sharpening rod 8-1 provides better sharpening effects for the tool grinding.

[0066] See Figures 1 to 3 In Specific Embodiment 2, this Specific Embodiment 2 provides a knife sharpening bracket. The difference between Specific Embodiment 2 and Specific Embodiment 1 is that the outer side surface of the knife sharpening bracket 5 is also provided with cowhide 8-2 for knife sharpening, such as two pieces of yellow cowhide 8-2, with a fine polishing surface and a rough polishing surface respectively, increasing the usage scenarios of the knife sharpening bracket 5. It can not only grind the tool, but also be used for polishing the tool.

[0067] The arc length of the cross-section of the opening part 5-1-1 is less than or equal to one-half of the circumference of the circle where the cross-section of the opening groove 5-1 is located, which can not only ensure that the sharpening rod 8-1 is installed in the opening part 5-1-1 and is not easy to fall off, but also make the area of the opening part 5-1-1 (i.e., the area of the sharpening surface 8-1-1) as large as possible, providing convenience for the tool to be ground on the sharpening surface 8-1-1 and avoiding the edge part of the opening groove 5-1 from affecting the tool grinding.

[0068] The knife sharpening bracket 5 is internally provided with a storage space for storing the sharpening rod 8-1 and / or the taper rod. The storage space can store spare sharpening rods 8-1 and / or taper rods. For example, select the sharpening rod 8-1 with the required grit from the spare sharpening rods, and then replace it in the opening groove 5-1 to achieve different functional knife sharpening effects through the knife sharpening bracket 5. The spare sharpening rods 8-1 and / or taper rods can be carried with the knife sharpening bracket 5, are not easy to lose, and are more convenient to use.

[0069] The top end of the knife sharpening support 5 is provided with a third blocking portion for abutting against the sharpening rod 8-1 and / or the taper rod in the storage space. For example, the third blocking portion is a third knob 5-3. The third knob 5-3 is detachably connected to one end of the knife sharpening support 5 (taper rod storage hole 5-2-1). The third knob 5-3 is threadedly connected to one end of the knife sharpening support 5 (such as the top end of the taper rod storage hole 5-2-1). For example, the inner side wall of one end of the taper rod storage hole 5-2-1 corresponding to the third knob 5-3 is provided with an internal thread matching the external thread of the third knob 5-3. After removing the third knob 5-3, it is very convenient to store the sharpening rod 8-1 and / or the taper rod in the storage space (such as the storage hole 5-2) or take out the sharpening rod 8-1 and / or the taper rod from the storage space. The third knob 5-3 can abut against the sharpening rod 8-1 and / or the taper rod in the storage space, preventing the sharpening rod 8-1 and / or the taper rod from sliding out from the top end of the storage hole 5-2.

[0070] The storage space is a number of storage holes 5-2, which are separately stored without interfering with each other, avoiding multiple sharpening rods 8-1 and / or taper rods from touching each other and causing damage.

[0071] In this Embodiment 2, the cross-section of the knife sharpening support 5 is hexagonal. Cowhide 8-2 is respectively arranged on two opposite sides, and opening grooves 5-1 are respectively arranged at two corners away from the cowhide 8-2, ensuring that there is no interference and they do not affect each other when grinding the tool or polishing the tool with the cowhide.

[0072] The storage space inside the knife sharpening support 5 is five storage holes 5-2. The storage hole 5-2 located in the middle part of the cross-section of the knife sharpening support 5 is a taper rod storage hole 5-2-1 for storing the taper rod. One of the remaining four storage holes 5-2 stores a spare diamond round tube sharpening rod 8-1 each, and the other two storage holes 5-2 store an alumina polishing ceramic rod each. Whether it is the diamond round tube sharpening rod 8-1 or the alumina polishing ceramic rod, it can be installed in the opening groove 5-1 to achieve the corresponding tool grinding function.

[0073] The shape of the knife sharpening support 5, the number and position of the storage holes 5-2 can be adjusted according to actual needs, not limited to the cross-section of the knife sharpening support 5 being hexagonal and having five storage holes 5-2.

[0074] The bottom end of the knife sharpening support 5 is connected to a third connecting member 6. The third connecting member 6 is used to fix the knife sharpening support 5 on other components (such as the handle 7), facilitating the user to indirectly fix the knife sharpening support 5 by holding other components (such as the handle 7) when grinding the tool to achieve the knife sharpening operation.

[0075] In the second embodiment, the third knob 5-3 and the third connecting member 6 are respectively located at two ends of the knife sharpening bracket 5. At this time, the storage holes 5-2 are open at the two ends of the knife sharpening bracket 5. Therefore, the third knob 5-3 and the third connecting member 6 respectively abut against the two ends of the grinding rod 8-1 and / or the taper rod in the storage holes 5-2, so as to realize the storage of the grinding rod 8-1 and / or the taper rod by the knife sharpening bracket 5.

[0076] The third connecting member 6 is divided into a connecting section A6-1 and a connecting section B6-2. The connecting section A6-1 is embedded in the other end of the knife sharpening bracket 5 (the bottom end of the taper rod storage hole 5-2-1), so as to realize the connection between the third connecting member 6 and the knife sharpening bracket 5. For example, the connecting section A6-1 is in the shape of a round rod, and a knurled portion 6-1-4 is provided on the outer side surface of the connecting section A6-1. After the connecting section A6-1 is embedded in the other end of the taper rod storage hole 5-2-1, the knurled portion 6-1-4 and the other end of the taper rod storage hole 5-2-1 are in interference fit to realize the connection between the third connecting member 6 and the knife sharpening bracket 5. Preferably, the knurled portion 6-1-4 is located at a position on the connecting section A6-1 close to the connecting section B6-2. The connecting section A6-1 is also provided with a third through hole 6-1-5, such as a radial third through hole 6-1-5. By using the design of the knurled portion 6-1-4 and the third through hole 6-1-5, the assembly accuracy requirements that the two ends of the opening groove 5-1 on the knife sharpening bracket 5 are respectively aligned with the two third guiding portions 2-1-3 on the first inclined surface 2-1 can be met, and the assembly speed and position accuracy of the third connecting member 6 with the first bracket 1 and the knife sharpening bracket 5 can be improved.

[0077] The specific assembly steps are as follows. First, embed a part of the connecting section A6-1 into the other end of the taper rod receiving hole 5-2-1 (at this time, the connecting section A6-1 and the taper rod receiving hole 5-2-1 are pre-riveted, but their circumferential positions can be adjusted), and keep the knurled part 6-1-4 and the third through hole 6-1-5 outside the taper rod receiving hole 5-2-1. Second, rotate the third connecting piece 6 and the knife grinding bracket 5 together so that the fourth external thread 6-2-4 locks with the fourth internal thread 1-13-2. Then, insert a pin (not shown in the drawings) through the third through hole 6-1-5, and rotate the pin to drive the third connecting piece 6 and the knife grinding bracket 5 to rotate together, so as to lock the fourth external thread 6-2-4 and the fourth internal thread 1-13-2 (that is, to realize the threaded connection between the first bracket 1 and the third connecting piece 6). Third, keep the first bracket 1 and the third connecting piece 6 stationary, and rotate the knife grinding bracket 5 sleeved on the connecting section A6-1 circumferentially until the two ends of the opening groove 5-1 on the knife grinding bracket 5 are respectively aligned with the two third guiding parts 2-1-3 on the first inclined surface 2-1. Then, use the pin to rotate reversely, and the third connecting piece 6 and the knife grinding bracket 5 rotate reversely together until the fourth external thread 6-2-4 is separated from the fourth internal thread 1-13-2, and the first bracket 1 and the third connecting piece 6 are disassembled, so that the third connecting piece 6 and the knife grinding bracket 5 can be removed from the first bracket 1 together. During this process, there is no circumferential rotation between the third connecting piece 6 and the knife grinding bracket 5. Finally, remove the pin, and rivet the removed knife grinding bracket 5 and the connecting section A6-1, that is, rivet the knurled part 6-1-4 and the taper rod receiving hole 5-2-1 to the end, forming an interference fit between the knurled part 6-1-4 and the other end of the taper rod receiving hole 5-2-1, and the connecting section A6-1 and the knife grinding bracket 5 are fixed both axially and circumferentially. Thus, the circumferential position calibration between the fourth external thread 6-2-4 and the opening groove 5-1 on the knife grinding bracket 5 is completed. Subsequently, as long as the user locks the fourth external thread 6-2-4 and the fourth internal thread 1-13-2, it can be ensured that the two ends of the opening groove 5-1 on the knife grinding bracket 5 are respectively aligned with the two third guiding parts 2-1-3 on the first inclined surface 2-1, making the installation between the knife grinding bracket 5 and the first bracket 1 efficient and highly accurate.

[0078] See Figure 3 、 Figure 4 、 Figures 8 to 9 For specific embodiment 3, this embodiment 3 provides a knife grinding bracket. The difference between embodiment 3 and the foregoing embodiments is that the third button cover 5-3-1 of the third knob 5-3 is in the shape of a frustum of a cone, which can effectively prevent the tool from colliding with the third button cover 5-3-1 when grinding the tool (such as swinging the knife), thus protecting the tool.

[0079] The outer side surface of the third button cover 5-3-1 is provided with a third anti-slip part 5-3-2. For example, the third anti-slip part 5-3-2 is a mesh-shaped anti-slip pattern, which is convenient for installing and disassembling the third knob 5-3.

[0080] The top of the third button cover 5-3-1 is provided with a fourth anti-slip portion 5-3-3. The fourth anti-slip portion 5-3-3 includes a plurality of annular anti-slip lines. When it is necessary to place the entire adjustable-angle protractor upright, for example, the top of the third button cover 5-3-1 abuts against the tabletop (or other fixed components, such as a wooden board, etc.), the fourth anti-slip portion 5-3-3 plays an anti-slip role between the third button cover 5-3-1 and the tabletop. The design of the plurality of concentric annular anti-slip lines of the fourth anti-slip portion 5-3-3 can maintain the same friction at any horizontal angle and achieve the same anti-slip effect, making it safer to use.

[0081] See Figure 2 、 Figure 3 Figure 4 and Figure 9 In specific embodiment 4, this embodiment 4 provides a sharpening bracket. The difference between embodiment 4 and the foregoing embodiments is that a gasket 6-5 for abutting against the sharpening rod 8-1 in the receiving hole 5-2 is provided at the connection between the connection section A6-1 and the connection section B6-2 of the third connecting member 6. For example, an annular gasket is made of metal to increase the rigidity of the gasket. The outer side surface of the connection section B6-2 of the third connecting member 6 is provided with a fourth external thread 6-2-4.

[0082] A reserved gap 5-4 is provided between the third button cover 5-3-1 of the third knob 5-3 and the top of the sharpening bracket 5. A first buffer portion 5-4-1, such as a silica gel buffer pad, is provided in the reserved gap to better prevent collision between the sharpening rod 8-1 and the third button cover 5-3-1 and avoid generating noise. The first buffer portion 5-4-1 fills the reserved gap 5-4 to flatten the top of the sharpening rod 8-1 and the sharpening bracket 5, eliminate the movement gap of the sharpening rod 8-1, avoid collision between the sharpening rod 8-1 and the third button cover 5-3-1, and avoid generating noise.

[0083] See Figure 10 In specific embodiment 5, this embodiment 5 provides a sharpening bracket. The difference between embodiment 5 and the foregoing embodiments is that the third connecting member 6 can be made of metal. The connection section A6-1 of the third connecting member 6 is a circular structure as a whole. The outer side surface of the connection section A6-1 is provided with anti-slip teeth 6-1-3. When the connection section A6-1 is embedded in the sharpening bracket 5 (such as the taper rod receiving hole 5-2-1), the anti-slip teeth 6-1-3 are fixed to the inside of the sharpening bracket 5 (such as the taper rod receiving hole 5-2-1) by press riveting to prevent the third connecting member 6 from slipping off the sharpening bracket 5.

[0084] In addition, a second buffer portion 5-4-2, such as a silica gel buffer pad, can be added between the connection section A6-1 of the third connecting member 6 and the taper rod 8-3 to better prevent collision between the taper rod 8-3 and the third connecting member 6 and avoid generating noise.

[0085] See Figures 11 to 15 , Specific Example 6. This Specific Example 6 provides a knife sharpening bracket. The difference between Specific Example 6 and the foregoing examples is that the third connecting member 6 is divided into a connecting section A6-1 and a connecting section B6-2. A third hollow portion 6-1-1 is provided inside the connecting section A6-1, and a third serrated portion 6-1-2 is provided on the outer side surface of the connecting section A6-1. The connecting section A6-1 is embedded into the other end (the bottom end of the taper rod receiving hole 5-2-1) of the knife sharpening bracket 5 to realize the connection between the third connecting member 6 and the knife sharpening bracket 5. During the installation process of the third connecting member 6 and the knife sharpening bracket 5, by pressing the third hollow portion 6-1-1, the connecting section A6-1 can be better embedded into the knife sharpening bracket 5 (such as the taper rod receiving hole 5-2-1). When the connecting section A6-1 is embedded into the knife sharpening bracket 5, the connecting section A6-1 utilizes its own elasticity, the third hollow portion 6-1-1 restores its shape, and the third serrated portion 6-1-2 increases the friction force between the connecting section A6-1 and the inner side wall of the knife sharpening bracket 5 (such as the taper rod receiving hole 5-2-1), enhancing the connection strength between the third connecting member 6 and the knife sharpening bracket 5.

[0086] A third limiting protrusion 6-4 for abutting against the sharpening rod 8-1 and / or the taper rod in the receiving hole 5-2 is provided at the connection between the connecting section A6-1 and the connecting section B6-2. The third limiting protrusion 6-4 can also be used to abut against the sharpening rod 8-1 and / or the taper rod in the receiving hole 5-2 to prevent the sharpening rod 8-1 and / or the taper rod from sliding out from the bottom end of the receiving hole 5-2.

[0087] Specifically, after the third connecting member 6 (i.e., the connecting section A6-1) is embedded into the knife sharpening bracket 5, the top end of the connecting section A6-1 can also be used to abut against the taper rod, cooperating with the third knob 5-3 to receive and limit the taper rod in the taper rod receiving hole 5-2-1 and prevent the taper rod from accidentally shaking. The third limiting protrusion 6-4 abuts against the sharpening rod 8-1 in the other four receiving holes 5-2 to prevent the sharpening rod 8-1 from sliding out from the bottom end of the receiving hole 5-2. Moreover, the third limiting protrusion 6-4 does not completely cover the end of the receiving hole 5-2, facilitating the user to observe whether there is a sharpening rod 8-1 and / or a taper rod in the corresponding receiving hole 5-2.

[0088] The third knob 5-3 and the third connecting member 6 are located at both ends of the knife sharpening bracket 5. At this time, the receiving hole 5-2 is open at both ends corresponding to the knife sharpening bracket 5. Therefore, the third knob 5-3 and the third connecting member 6 respectively abut against both ends of the sharpening rod 8-1 and / or the taper rod in the receiving hole 5-2.

[0089] The connecting section B6-2 is provided with a third axial hole 6-2-1 for installing the metal insert 6-3. The metal insert 6-3 can be a cylindrical metal bar, such as an iron shaft or a stainless steel shaft. After the connecting section A6-1 is inserted into the grinding tool holder 5 (such as the bottom end of the taper rod receiving hole 5-2-1), the cylindrical metal bar is then inserted into the third axial hole 6-2-1. The third axial hole 6-2-1 can extend into the connecting section A6-1. The presence of the metal insert 6-3 increases the radial pressure between the third connecting member 6 (i.e., the connecting section A6-1) and the inner bottom of the taper rod receiving hole 5-2-1, preventing the third connecting member 6 from falling off the grinding tool holder 5. In addition, it also strengthens the strength of the third connecting member 6 (especially the connecting section B6-2), and the connecting section B6-2 is not easily broken accidentally.

[0090] The outer side wall of the grinding tool holder 5 is provided with a third positioning concave portion 5-5 to prevent the tool from colliding with the grinding tool holder 5 when grinding the tool.

[0091] The outer side surface of the connecting section B6-2 is provided with a positioning surface B6-2-3, which plays a role in preventing misassembly when fixing the grinding tool holder 5 to other components (such as the handle 7).

[0092] See Figure 15 , Specific Embodiment 7. This Specific Embodiment 7 provides a grinding tool holder. The difference between Specific Embodiment 7 and the foregoing embodiments is that a third buffer portion 6-6 for abutting against the grinding rod 8-1, such as a silica gel buffer pad, is provided at the connection between the connecting section A6-1 and the connecting section B6-2 of the third connecting member 6, which better prevents collision between the grinding rod 8-1 and the third connecting member 6 and avoids generating noise.

[0093] At this time, the third knob 5-3 can be directly pressed onto the grinding rod 8-1 to press the grinding rod 8-1 tightly. The third knob 5-3 is not pressed onto the grinding tool holder 5, so that there is no play in the grinding rod 8-1 either, avoiding generating noise.

[0094] See Figure 16 , Specific Embodiment 8. This Specific Embodiment 8 provides a knife sharpener, including a handle 7. The knife sharpener further includes a grinding tool holder in the above specific embodiment, and the handle 7 is connected to the connecting section B6-2. The user holds the handle 7 to fix the entire knife sharpener, facilitating the grinding of the tool using the grinding rod 8-1 in the opening groove 5-1 of the grinding tool holder 5.

[0095] The handle 7 is provided with a connection groove (not shown in the drawings), and the internal thread of the connection groove is connected to the fourth external thread 6-2-4 on the outer side surface of the connecting section B6-2 to realize the connection between the handle 7 and the grinding tool holder 5.

[0096] See Figure 17, Specific Embodiment 9. This embodiment 9 provides a knife sharpener. The difference between Embodiment 9 and Embodiment 8 is that a limiting groove (not shown in the drawings) can also be provided on the handle 7. The third limiting protrusion 6-4 matches the limiting groove. After the connecting section B6-2 is connected to the handle 7, the third limiting protrusion 6-4 is embedded in the limiting groove, which can effectively prevent the third connecting member 6 from rotating, can fix the angle of the third connecting member 6, and ultimately ensure that the sharpening rod 8-1 in the sharpening bracket 5 always maintains a fixed angle during the knife sharpening process, avoiding affecting the knife sharpening effect.

[0097] A connecting groove (not shown in the drawings) is provided on the handle 7. The connecting section B6-2 is provided with a radial third mounting hole 6-2-2. After the connecting section B6-2 is embedded in the connecting groove, the connecting section B6-2 and the handle 7 are fixedly connected through the third mounting hole 6-2-2 and the knob 7-8. At the same time, a positioning surface A (not shown in the drawings) is provided on the inner side wall of the connecting groove. The positioning surface A matches the positioning surface B6-2-3, which plays a role in preventing misassembly. That is, before the connecting section B6-2 is embedded in the connecting groove, the positioning surface B6-2-3 of the connecting section B6-2 corresponds to the positioning surface A of the connecting groove, and then it is embedded. In this way, it can be ensured that after the third connecting member 6 and the handle 7 are installed, the installation position of the sharpening bracket 5 and the handle 7 is accurate, improving the assembly efficiency. At the same time, the positioning surface A and the positioning surface B6-2-3 can also prevent the connecting section B6-2 from rotating, and ultimately prevent the handle 7 and the sharpening bracket 5 from rotating relative to each other, playing an anti-rotation role and ensuring a good knife sharpening effect.

[0098] Or the handle 7 is directly connected to the sharpening bracket 5 without passing through the third connecting member 6, and the purpose of connecting and fixing the two can also be achieved, which is convenient for sharpening knives.

[0099] Or the handle 7 is connected to the third connecting member 6. The third connecting member 6 may not be separately provided with a connecting section A and a connecting section B. As long as the third connecting member 6 can connect the handle 7 and the sharpening bracket 5, the purpose of connecting and fixing the handle 7 and the sharpening bracket 5 can also be achieved, which is convenient for sharpening knives.

[0100] The sharpening rod 8-1 is a hollow rod, which helps to reduce the overall weight of the knife sharpener and is convenient for carrying.

[0101] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present invention, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present invention.
