Description

Technical Field

[0002] Currently, the tool (such as "angle gauge") that provides the initial sharpening angle for the sharpening rod of the sharpening department has a fixed sharpening angle. Different inclination angles can only be changed by replacing the inclined surface. These inclination angles are also fixed, and the angle of the same inclined surface cannot be adjusted. If the inclined surface angle cannot be accurately adjusted, the grinding angle requirements of various knives cannot be met.

[0003] Therefore, how to make the inclination angle of the inclined surface in the angle gauge adjustable becomes a technical problem that needs to be solved.

[0004] Secondly, the existing knife sharpener has a sharpening rod installed in a rod body, which has only one tool sharpening function. When other tool sharpening functions are to be used, the sharpener can only be replaced, which is inconvenient to use and carry. How to make the knife sharpener have multiple sharpening functions (such as coarse grinding, fine grinding, polishing, etc.) has become a technical problem that needs to be solved.

[0005] Thirdly, the handle and the sharpening rod in the existing knife sharpener are connected as one body, which is relatively large in size and can only be placed in a tool box, which is inconvenient to store or carry around. Therefore, how to reduce the size of the knife sharpener, make it easier to store and carry around becomes a technical problem that needs to be solved.

[0006] Finally, users often need to twist arrows during outdoor activities, but existing sharpeners do not have the function of twisting arrows, and the function is too simple. Therefore, how to make the sharpener have the function of twisting arrows becomes a technical problem that needs to be solved. Utility Model Content

[0160] The present invention is further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used 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 claims attached to this application.

[0161] See also Figures 1 to 11 , Specific embodiment 1, this embodiment 1 provides an angle gauge with adjustable angle, which includes at least one group of angle adjustment mechanisms, each group of angle adjustment mechanisms includes a first bracket 1, a first bevel body 2, a push tube 3 and a first angle adjustment knob 4, the first bevel body 2 is provided with a first inclined surface 2-1 for tool sharpening, the so-called "first inclined surface 2-1 for tool sharpening" means that the first inclined surface 2-1 provides an initial angle for the tool, so that the tool maintains an accurate angle when sharpened on the sharpening rod 8-1, thereby improving the tool sharpening effect, and the push tube 3 is provided with a second inclined surface 3-1.

[0162] The first inclined body 2 is connected to the first bracket 1 in a flippable manner, such as an axial connection or a hinge connection, as long as the inclination angle of the first inclined surface 2-1 in the first inclined body 2 is changed or adjusted.

[0163] The first angle adjustment knob 4 and the push tube 3 are connected by threads to realize the axial movement of the push tube 3. The second inclined surface 3-1 drives the bottom of the higher end 2-1-1 of the first inclined surface in the first bevel body 2 to rise or fall, which can more efficiently lift the higher end 2-1-1 of the first inclined surface, adjust the inclination angle of the first inclined surface 2-1, provide different initial angles for the tool during the grinding process, and meet the angle requirements of various tool grinding. The higher end 2-1-1 of the first inclined surface generally refers to the end of the first inclined surface 2-1 away from the sharpening part (i.e., the horizontal line where the sharpening rod 8-1 is located). The lower end 2-1-2 of the first inclined surface generally refers to the end of the first inclined surface 2-1 close to the sharpening part (i.e., the horizontal line where the sharpening rod 8-1 is located).

[0164] The connection between the first inclined surface 2 and the first bracket 1 is close to the lower end 2-1-2 of the first inclined surface, so that the first inclined surface 2 and the first bracket 1 can be flipped and connected, and the angle adjustment of the first inclined surface 2-1 is more efficient and convenient, that is, on the basis of the original angle of the first inclined surface 2-1 itself (for example, 15°, the original angle value can be adjusted according to actual needs), the push tube 3 is moved forward (that is, the push tube 3 moves axially toward the first inclined surface 2), so that the second inclined surface 3-1 raises the bottom of the higher end 2-1-1 of the first inclined surface The first inclined surface 2-1 is adjusted to the angle of inclination of the first inclined surface 2-1, and the inclination angle of the first inclined surface 2-1 is quickly increased (for example, within the range of 15° to 30°, and the adjustment range of the inclination angle of the first inclined surface 2-1 can also be expanded according to actual needs). When the push tube 3 moves in the opposite direction (i.e., the push tube 3 moves axially away from the first inclined surface 2), as the second inclined surface 3-1 gradually returns to its original position, the bottom of the higher end 2-1-1 of the first inclined surface gradually falls, and the angle of the first inclined surface 2-1 gradually returns to its original angle. The adjustment process of the inclination angle of the first inclined surface 2-1 is more convenient and efficient, and the comfort of use is improved. For example, the first inclined surface 2 is a wedge or a wedge-shaped body.

[0165] The first bracket 1 is hollow inside, and the hollow part can be used to sleeve the push tube 3, so that the push tube 3 can realize axial movement inside the first bracket 1, thereby lifting the first bevel body 2 connected to the first mounting groove 1-1. The first bracket 1 is sleeved on the push tube 3 and also realizes the radial upper limit of the push tube 3, ensuring that the threaded connection between the push tube 3 and the first angle adjustment knob 4 is more stable and not easy to disengage. The first bracket 1 is provided with a first mounting groove 1-1, and the first bevel body 2 and the first mounting groove 1-1 are connected by a connecting shaft 1-3 (that is, the shaft mounting hole 2-3 of the first bevel body 2 is connected by a connecting shaft The connecting shaft 1-3 is connected to the first bracket 1, and the connection position between the two is also called the connection position between the first bevel body 2 and the first bracket 1). The first installation groove 1-1 connects the inside and outside of the first bracket 1, providing space for the flipping of the first bevel body 2, and more reasonably utilizing the internal space of the first bracket 1. At the same time, the first installation groove 1-1 limits the first bevel body 2 and the first inclined surface 2-1 to the position corresponding to the sharpening part or the sharpening rod 8-1, and finally realizes the adjustment effect of the inclination angle of the first inclined surface 2-1 and finally acts on the tool, providing a precise sharpening angle for tool grinding.

[0166] In the present embodiment 1, the outer side surface of the push tube 3 is provided with a first external thread 3-2, one end of the push tube 3 corresponding to the second inclined surface 3-1 is embedded in the first hollow part 1-2 of the first bracket 1, the second inclined surface 3-1 corresponds to the first inclined body 2, that is, the second inclined surface 3-1 faces the first inclined body 2, and the inclination angle of the first inclined surface 2-1 in the first inclined body 2 is gradually adjusted by the inclination angle of the second inclined surface 3-1. The first angle adjustment knob 4 is hollow inside and the inner side wall is provided with a first internal thread 4-2. The first angle adjustment knob 4 is sleeved with the push tube 3, and the first internal thread 4-2 matches the first external thread 3-2. The top of the first angle adjustment knob 4 is against the bottom of the first bracket 1, and the first bracket 1 limits the top of the first angle adjustment knob 4. The first angle adjustment knob 4 drives the push tube 3 to achieve axial movement through the threaded connection. For example, a first boss portion 1 - 15 is provided at the bottom of the first bracket 1 , and the first boss portion 1 - 15 is embedded in the inner wall of the top of the first angle adjustment knob 4 to achieve a radial limiting effect on the first bracket 1 and the first angle adjustment knob 4 .

[0167] The first bracket 1 is also provided with a hollow first guide groove 1-5, and the push tube 3 is also provided with a first protruding block 3-3, and the first protruding block 3-3 is embedded in the first guide groove 1-5. As the push tube 3 moves axially, the first protruding block 3-3 moves synchronously in the first guide groove 1-5. The outer wall of the first bracket 1 on both sides of the first guide groove 1-5 is also provided with a first mark 1-6 for displaying the angle value. The inclination angle of the first inclined surface 2-1 can be infinitely adjusted or changed, and the first mark 1-6 mainly marks the key angle value, that is, the first protruding block 3-3 cooperates with the first mark 1-6 to reflect the change of the inclination angle of the first inclined surface 2-1 in real time (for example, after the first inclined surface 3-1 of the push tube 3 lifts the first inclined body 2), so as to help the user adjust the inclination angle of the first inclined surface 2-1 more accurately. In addition, the first guide groove 1-5 not only limits the movement of the first protruding block 3-3, ensuring that the push tube 3 moves along the axial direction and indirectly preventing the push tube 3 from rotating in the circumferential direction, but the first guide groove 1-5 can also limit the up and down movement of the first protruding block 3-3, thereby indirectly limiting the axial movement distance of the push tube 3, that is, the axial limitation of the push tube 3, ensuring that the first external thread 3-2 and the first internal thread 4-2 between the push tube 3 and the first angle adjustment knob 4 are always connected, and the threads of the two will not be disengaged due to excessive rotation, which is convenient for the subsequent repeated use of the first angle adjustment knob 4, so that the push tube 3 can reciprocate axially, so that the adjustable angle gauge is always in a good working condition.

[0168] A second mark 1-8 for indicating the rotation direction of the first angle adjustment knob 4 is provided near the first guide groove 1-5, that is, it indicates to the user the rotation direction of the first angle adjustment knob 4 corresponding to the increase of the inclination angle of the first inclined surface 2-1, and the rotation direction of the first angle adjustment knob 4 corresponding to the decrease of the inclination angle of the first inclined surface 2-1, thereby improving the convenience and comfort of use.

[0169] A first elastic body 1-4 (such as a U-shaped spring clip) is also provided between the first bracket 1 and the first bevel body 2 for driving the first bevel body 2 to reset. The first elastic body 1-4 and the push tube 3 are respectively located on both sides of the connecting shaft 1-3. When the push tube 3 moves axially toward the first bevel body 2 (i.e., moves in the positive direction), the second inclined surface 3-1 gradually moves forward, and the bottom of the higher end 2-1-1 of the first inclined surface in the first bevel body 2 is gradually lifted by the second inclined surface 3-1. At this time, the first bevel body 2 rotates around the connecting shaft 1-3 to increase the inclination angle of the first inclined surface 2-1. At the same time, the bottom of the lower end 2-1-2 of the first inclined surface compresses the first elastic body 1-4 or further compresses the second bevel body 2. An elastic body 1-4, when the push tube 3 moves axially in the direction away from the first bevel body 2 (i.e., moves in the reverse direction), the second inclined surface 3-1 gradually retreats, and at this time the first elastic body 1-4 pushes the bottom of the lower end 2-1-2 of the first inclined surface, and the first bevel body 2 rotates in the opposite direction with the connecting shaft 1-3 as the center, and the bottom of the higher end 2-1-1 of the first inclined surface is pressed down, and gradually descends along the second inclined surface 3-1 until it is reset (i.e., the bottom of the higher end of the first bevel body 2 slides to the bottom, and at this time the inclination angle of the first inclined surface 2-1 is its original inclination angle), thereby achieving the effect of automatic reset of the first bevel surface 2-1 and automatic retraction of the first bevel body 2 into the first mounting groove 1-1.

[0170] In this embodiment 1, the first inclined surface 2-1 faces away from the push tube 3, so that the push tube 3 can move axially to adjust the inclination angle of the first inclined surface 2-1. The first inclined surface 2-1 faces away from the first bracket 1, so that the first inclined surface 2-1 can be used to grind the tool. Generally, the lower end 2-1-2 of the first inclined surface faces the grinding part, so that the first inclined surface 2-1 can be used in conjunction with the grinding part to achieve precise grinding of the tool blade.

[0171] The angle gauge with adjustable angle in the present embodiment 1 can meet the grinding requirements of different types of tools by adjusting the inclination angle of the first inclined surface 2-1. It is suitable for most tools and greatly expands the application scope of tool grinding. There is no need to replace angle gauges with other fixed angle values ​​as in the prior art, which saves costs and is more convenient and comfortable to use.

[0172] In addition, the inclination angle of the first inclined surface 2-1 can theoretically be infinitely adjusted, for example, any angle within the range of 15° to 30° can be achieved. Of course, the angle range of 15° to 30° can also be adjusted according to actual conditions.

[0173] In this embodiment 1, two groups of angle adjustment mechanisms are taken as an example. Two groups of first mounting grooves 1-1 and first bevel bodies 2 and a first guide groove 1-5 are respectively arranged around the first bracket 1. The two first bevel bodies 2 are opposite to each other and correspond to the open grooves 5-1 on the knife sharpening bracket 5 (that is, each first bevel body 2 corresponds to an open groove 5-1), and the first guide groove 1-5 corresponds to a cowhide 8-2 for sharpening the knife.

[0174] The side of the first bracket 1 corresponding to the first mounting groove 1-1 is the fourth inclined surface 1-12. The inclination angle of the fourth inclined surface 1-12 is the same as the inclination angle of the first inclined surface 2-1. When the first bevel body 2 falls to the lowest point, that is, when the second inclined surface 3-1 leaves the bottom of the first bevel body 2, the inclination angle of the first bevel body 2-1 at this time is the angle of the first bevel body 2 itself, that is, the unadjusted angle. At this time, the first bevel surface 2-1 and the fourth bevel surface 1-12 are flush, and the two are on the same plane, the appearance is more beautiful, and the first bevel body 2 is also completely received in the first mounting groove 1-1. When the inclination angle of the first bevel surface 2-1 needs to be adjusted, one end of the first bevel body 2 will be gradually lifted up, and one end of the first bevel body 2 will slowly protrude from the fourth inclined surface 1-12. At this time, the fourth inclined surface 1-12 will not cause any interference to the inclination angle of the first bevel surface 2-1 before and after. According to actual conditions, the inclination angle of the fourth inclined surface 1-12 and the inclination angle of the first inclined surface 2-1 (ie, the angle of the top of the first inclined surface 2) may also be different.

[0175] A third inclined surface 1-9 is provided on the first bracket 1 at a position corresponding to the top of the first guide groove 1-5. The third inclined surface 1-9 provides an initial angle for the tool to grind on the cowhide 8-2. For example, the angle of the third inclined surface 1-9 is 20°, and the angle of the third inclined surface 1-9 is not adjustable.

[0176] The angle gauge with adjustable angle in this embodiment 1 can adjust the inclination angle of the first inclined surface 2-1 arbitrarily by rotating the first angle adjustment knob 4, so as to provide a sharpening angle for various knives. The angle gauge can be connected to the sharpening rod of any sharpener, and can be used in conjunction with the sharpening rod to sharpen various knives. The scope of use is wide, and the initial angle provided by the angle gauge can be adjusted.

[0177] The angle gauge with adjustable angle can be used alone, for example, by placing the angle gauge on the grinding surface of the whetstone (ceramic plate, diamond plate or other grinding tool), and providing the tool with an initial grinding angle through an inclined surface (such as the first inclined surface 2-1). The inclination angle of the first inclined surface 2-1 can also be adjusted according to actual needs.

[0178] See also Figure 1 , 2 and Figure 5, specific embodiment 2, this embodiment 2 provides an angle gauge with adjustable angle. The difference between embodiment 2 and embodiment 1 is that the outer side surface of the first angle adjustment knob 4 is provided with a first anti-slip portion 4-1. The first anti-slip portion 4-1 is, for example, a mesh anti-slip pattern, which is more suitable for hand twisting. The first angle adjustment knob 4 can be made of metal with good texture.

[0179] The first inclined surface 2-1 of the first bevel body 2 is provided with a third guiding portion 2-1-3, for example, the third guiding portion 2-1-3 is formed by two straight-line grooves. For example, when the first bracket 1 and the third connecting member 6 are fixed by threaded connection, when the third connecting member 6 is tightened, the third guiding portion 2-1-3 is aligned with the two ends of the opening groove 5-1 of the sharpening bracket 5 or the outer circle of the sharpening rod 8-1, it indicates that the installation position of the sharpening bracket 5 and the first bracket 1 is accurate and has been installed in place.

[0180] See also Figures 12 to 15 , Specific embodiment 3, this embodiment 3 provides an angle gauge with adjustable angle. The difference between embodiment 3 and the previous embodiment is that the angle gauge includes a first bracket 1, a first bevel body 2 and an angle adjustment member. The first bevel body 2 is provided with a first inclined surface 2-1 for tool sharpening, and the angle adjustment member is provided with a second inclined surface 3-1; the first bevel body 2 is connected to the first bracket 1 in a flippable manner, and by moving the angle adjustment member, the second inclined surface 3-1 drives the bottom of the higher end 2-1-1 of the first inclined surface in the first bevel body 2 to rise or fall, thereby adjusting the inclination angle of the first inclined surface 2-1.

[0181] The first bracket 1 is provided with a plurality of first positioning grooves 1-14, the angle adjustment member is a push block 30, the push block 30 is provided with an elastic pressing portion 30-1, the elastic pressing portion 30-1 is connected to a convex point 30-2 (or also called a clamping point), and the convex point 30-2 matches with the corresponding first positioning groove 1-14 to realize the positioning of the push block 30 after movement. A second elastic body 30-3, such as a spring, is provided between the push block 30 and the elastic pressing portion 30-1.

[0182] The first bracket 1 is also provided with a hollow first guide groove 1-5, and the elastic pressing part 30-1 is embedded in the first guide groove 1-5. When the elastic pressing part 30-1 moves with the push block 30, the elastic pressing part 30-1 moves synchronously along the first guide groove 1-5. At this time, the first guide groove 1-5 limits the moving trajectory of the elastic pressing part 30-1.

[0183] As the push block 30 moves, the first protruding block 3-3 moves synchronously in the first guide groove 1-5; a first mark 1-6 displaying the angle value is also provided on the outer wall of the first bracket 1 on one side or both sides of the first guide groove 1-5, and a plurality of first positioning grooves 1-14 are arranged corresponding to the first mark 1-6. For example, a plurality of first positioning grooves 1-14 correspond to different angles of the first mark 1-6. When the protrusion 302 is embedded in different first positioning grooves 1-14, the push block 30 also moves synchronously to different positions, and the first inclined surface 2-1 is adjusted to achieve different inclination angles. At this time, the position of the elastic pressing portion 30-1 also corresponds to the corresponding angle value of the first mark 1-6. The elastic pressing portion 30-1 also serves as an angle indicator, so that the inclination angle of the first inclined surface 2-1 can be visualized.

[0184] The angle gauge in the present embodiment 3 is used as follows: by pressing the elastic pressing part 30-1, the protrusion 30-2 and the first positioning groove 1-14 are separated, and at the same time, the elastic pressing part 30-1 is pushed to move, driving the push block 30 to move (for example, along the axial direction), and the second inclined surface 3-1 drives the bottom of the higher end 2-1-1 of the first inclined surface in the first inclined body 2 to rise or fall to the corresponding angle, that is, adjust the inclination angle of the first inclined surface 2-1 to the specified angle, and then release the elastic pressing part 30-1. At this time, the protrusion 30-2 is embedded in the corresponding first positioning groove 1-14 to form a limiting structure, so that the position of the push block 30 is fixed (for example, the axial position is fixed), and no movement occurs, thereby ensuring that the inclination angle of the first inclined surface 2-1 remains unchanged.

[0185] The push block 30 can be in the shape of a push tube or other shapes. As long as the push block 30 can move as an angle adjustment member, the second inclined surface 3-1 can be used to drive the bottom of the higher end 2-1-1 of the first inclined surface in the first inclined body 2 to rise or fall, thereby adjusting the inclination angle of the first inclined surface 2-1.

[0186] The first bevel body 2 is provided with an extension portion 2-4, which is connected to one end of the third elastic body 30-4. The other end of the third elastic body 30-4 is connected to or abuts against the inner wall of the first bracket 1. The third elastic body 30-4 helps the first bevel body 2 to reset. When the inclination angle of the first inclined surface 2-1 is restored, the first inclined surface 2-1 automatically retracts until it is reset, and no additional operation is required by the user.

[0187] See also Figures 9 and 10 , Specific embodiment 4, this embodiment 4 provides an angle gauge with adjustable angle, and the difference between embodiment 4 and the previous embodiment is that the top of the first bracket 1 is provided with a first connecting groove

[0188] 1-13, the first connecting groove 1-13 is used to connect the sharpening bracket 5 and / or the sharpening rod and / or the cone rod.

[0189] The first connecting groove 1-13 is located on the axis of the first bracket 1, so that after the first bracket 1 is installed with the sharpening part (such as the sharpening bracket 5), the first inclined surface 2-1 of the angle gauge corresponds to the sharpening rod 8-1 or the sharpening surface of the sharpening part, which is convenient for using the angle gauge to sharpen the tool on the sharpening rod 8-1.

[0190] Alternatively, the sharpening part may directly use a sharpening rod, one end of which is connected and fixed to the first connecting groove 1-13, and the first inclined surface 2-1 of the angle gauge corresponds to the sharpening rod, so that the tool can be sharpened on the sharpening rod 8-1 using the angle gauge.

[0191] See also Figures 16 to 28 , specific embodiment 5, this embodiment 5 provides an angle gauge with adjustable angle. The difference between embodiment 5 and the previous embodiment is that the push tube 3 is provided with four second inclined surfaces 3-1, each second inclined surface 3-1 corresponds to a first inclined surface body 2, and the four first inclined surfaces 2 are distributed around the first bracket 1, such as around the top of the first bracket 1 or in four directions, so as to make fuller use of the sharpening part on the sharpening rod to sharpen the tool.

[0192] The four first inclined plane bodies 2 are all connected to the fourth elastic body 10 (for example, an O-shaped elastic ring). When the push tube moves in the opposite direction, the four first inclined plane bodies 2 are automatically reset synchronously under the action of the fourth elastic body 10, and the first inclined plane bodies 2 automatically retract into the first installation groove 1-1. For example, a hook 2-6 is provided at the bottom of each first inclined plane body 2, and the hooks 2-6 of the four first inclined plane bodies 2 are all hung with the same fourth elastic body 10 (for example, an O-shaped elastic ring).

[0193] The first bracket 1 is provided with an indicating part 1-16, and the outer side surface of the first angle adjustment knob 4 is provided with a third mark 4-3, the indicating part 1-16 and the third mark 4-3 cooperate with each other, and the third mark 4-3 includes a mark of the rotation direction of the first angle adjustment knob 4 and / or a mark of the rotation angle value of the first angle adjustment knob 4, and displays the rotation direction and / or the rotation angle value of the first angle adjustment knob 4. The user can select the rotation direction of the first angle adjustment knob 4 according to the third mark 4-3 to realize rapid adjustment of the inclination angle of the first inclined surface 2-1, and help the user quickly judge the rotation amplitude of the first angle adjustment knob 4 according to different angle values ​​in the third mark corresponding to the indicating part 1-16.

[0194] Specific embodiment 6, this embodiment 6 provides an angle gauge with adjustable angle. The difference between embodiment 6 and the previous embodiments is that the angle gauge can also be provided with three sets of angle adjustment mechanisms, and the three first inclined surfaces 2-1 respectively correspond to two different sharpening rods or different sharpening surfaces of the same sharpening rod or different sharpening plane positions on the sharpening plate (such as a ceramic plate or a diamond plate, etc.).

[0195] Or the angle gauge can also be provided with five groups of angle adjustment mechanisms, and the five first inclined surfaces 2-1 correspond to two different sharpening rods or different sharpening surfaces of the same sharpening rod or different sharpening plane positions on the sharpening board.

[0196] Or the angle gauge can also be provided with six groups of angle adjustment mechanisms, and the six first inclined surfaces 2-1 correspond to two different sharpening rods or different sharpening surfaces of the same sharpening rod or different sharpening plane positions on the sharpening board.

[0197] Or the angle gauge can also be provided with eight groups of angle adjustment mechanisms, and the eight first inclined surfaces 2-1 correspond to two different sharpening rods or different sharpening surfaces of the same sharpening rod or different sharpening plane positions on the sharpening board.

[0198] Specific embodiment 7, this embodiment 7 provides an angle gauge with adjustable angle, which includes a group of angle adjustment mechanisms, which include a first bracket 1, a first bevel body 2 and an angle adjustment member, the first bevel body 2 is provided with a first inclined surface 2-1, and the angle adjustment member is provided with a second inclined surface 3-1; the first bevel body 2 is flipably connected to the first bracket 1, and by moving the angle adjustment member, the second inclined surface 3-1 drives one end of the first bevel body 2 to rise or fall, thereby adjusting the inclination angle of the first inclined surface 2-1; the first inclined surface 2-1 provides different initial angles for the tool to be sharpened on the sharpening rod.

[0199] For example, the second inclined surface 3-1 drives the bottom of the higher end 2-1-1 of the first inclined surface in the first inclined body 2 to rise or fall, thereby adjusting the inclination angle of the first inclined surface 2-1;

[0200] The connection between the first inclined body 2 and the first bracket 1 is close to the lower end 2-1-2 of the first inclined surface;

[0201] The angle adjustment member moves from the higher direction to the lower direction of the first inclined surface 2-1, so that the bottom of the first inclined body 2 corresponding to the higher end 2-1-1 of the first inclined surface is gradually raised along the second inclined surface 3-1, and the inclination angle of the first inclined surface 2-1 is gradually increased. The angle adjustment member moves from the lower direction to the higher direction of the first inclined surface 2-1, so that the bottom of the first inclined body 2 corresponding to the higher end 2-1-1 of the first inclined surface is gradually dropped along the second inclined surface 3-1, and the inclination angle of the first inclined surface 2-1 is gradually reduced.

[0202] The first inclined surface body 2 and the angle adjustment member may be wedge-shaped bodies or wedge bodies, or may be bodies of other shapes with corresponding inclined surfaces capable of realizing the corresponding functions of the two inclined surfaces.

The knife sharpening part includes a knife sharpening bracket 5 and a knife sharpening rod 8-1. The knife sharpening bracket 5 is provided with a storage space for storing the knife sharpening rod 8-1 and / or the cone rod 8-3.

The third connecting member 6 can be an injection molded part. 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 cone rod receiving hole 5-2-1 to achieve the connection between the third connecting member 6 and the knife sharpening bracket 5. The outer side surface of the connecting section B6-2 of the third connecting member 6 is provided with a fourth external thread 6-2-4 for connecting to the first bracket 1. For example, the first connecting groove 1-13 is provided with a fourth internal thread 1-13-2 (at this time, the fourth internal thread 1-13-2 can also be the third internal thread 9-1 of the threaded insert 9, one end of the threaded insert 9 extends to the opening of the first connecting groove 1-13, and the fourth internal thread 1-13-2 can also be a separately added internal thread), and the fourth internal thread 1-13-2 matches the fourth external thread 6-2-4 to achieve the connection between the first bracket 1 and the third connecting member 6.

[0205] Preferably, a gasket 6-5, such as an annular gasket made of metal, is provided at the connection between the connection section A6-1 and the connection section B6-2 of the third connecting member 6 for resisting the sharpening rod 8-1 in the storage hole 5-2 to increase the rigidity of the gasket.

[0206] The connecting section A6-1 of the third connecting member 6 is a round rod, and a knurled portion 6-1-4 is provided on the outer side of the connecting section A6-1. After the connecting section A6-1 is embedded in the other end of the cone rod receiving hole 5-2-1, the knurled portion 6-1-4 and the other end of the cone rod receiving hole 5-2-1 are interference fit to achieve the connection between the third connecting member 6 and the sharpening bracket 5. Preferably, the knurled portion 6-1-4 is located on the connecting section A6-1 near 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. The design of the knurled portion 6-1-4 and the third through hole 6-1-5 can meet the assembly accuracy requirements of aligning the two ends of the opening groove 5-1 on the sharpening bracket 5 with the two third guide portions 2-1-3 on the first inclined surface 2-1, respectively, and improve the assembly speed and position accuracy of the third connecting member 6 with the first bracket 1 and the sharpening bracket 5.

[0207] The specific assembly steps are as follows: first, embed a portion of the connecting section A6-1 into the other end of the cone rod receiving hole 5-2-1 (at this time, the connecting section A6-1 and the cone rod receiving hole 5-2-1 have been pre-riveted, but the circumferential positions of the two are adjustable), and keep the knurled portion 6-1-4 and the third through hole 6-1-5 located outside the cone rod receiving hole 5-2-1. Secondly, rotate the third connecting member 6 and the sharpening bracket 5 together so that the fourth external thread 6-2-4 is locked with the fourth internal thread 1-13-2. Then, pass the latch (not shown in the attached figure) through the third through hole 6-1-5, and rotate the latch to drive the third connecting member 6 and the sharpening bracket 5 to rotate together, so as to achieve the locking of the fourth external thread 6-2-4 with the fourth internal thread 1-13-2 (i.e., achieve the threaded connection between the first bracket 1 and the third connecting member 6). Once again, the first bracket 1 and the third connecting member 6 are kept stationary, and the knife sharpening bracket 5 sleeved on the connecting section A6-1 is rotated circumferentially until 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. Then, the third connecting member 6 and the knife sharpening bracket 5 are rotated in the reverse direction by using the latch, 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 member 6 are separated, so that the third connecting member 6 and the knife sharpening bracket 5 can be removed from the first bracket 1 together. In this process, the third connecting member 6 and the knife sharpening bracket 5 do not rotate in the circumferential direction. Finally, remove the latch, and rivet the removed sharpening bracket 5 and the connecting section A6-1, that is, rivet the knurled portion 6-1-4 and the cone rod receiving hole 5-2-1 to the bottom, forming an interference fit between the knurled portion 6-1-4 and the other end of the cone rod receiving hole 5-2-1, and the connecting section A6-1 is fixed to the sharpening bracket 5 in both the axial and circumferential directions. At this point, the circumferential position calibration of the fourth external thread 6-2-4 and the open groove 5-1 on the sharpening bracket 5 is completed. Subsequent users only need to lock the fourth external thread 6-2-4 with the fourth internal thread 1-13-2 to ensure that the two ends of the open groove 5-1 on the sharpening bracket 5 are respectively aligned with the two third guide portions 2-1-3 on the first inclined surface 2-1, so that the installation between the sharpening bracket 5 and the first bracket 1 is efficient and accurate.

[0208] A third knob 5-3 is provided at the top of the sharpening bracket 5 for supporting the sharpening rod 8-1 and / or the tapered rod 8-3 in the storage space. For example, the third knob 5-3 is threadedly connected to the top of the sharpening bracket 5 (for example, the top of the tapered rod storage hole 5-2-1). After the third knob 5-3 is removed, the sharpening rod 8-1 and / or the tapered rod 8-3 can be conveniently stored in the storage space (for example, the storage hole 5-2) or taken out from the storage space. The third knob 5-3 can support the sharpening rod 8-1 and / or the tapered rod 8-3 in the storage space to prevent the sharpening rod 8-1 and / or the tapered rod 8-3 from slipping out from the top of the storage hole 5-2. After the third connecting member 6 is embedded in the knife sharpening bracket 5, the top of the connecting section A6-1 can also be used to resist the cone rod 8-3, and cooperate with the third knob 5-3 to store and confine the cone rod 8-3 in the cone rod storage hole 5-2-1, and prevent the cone rod 8-3 from shaking accidentally.

[0209] Preferably, the third button cover 5-3-1 of the third knob 5-3 is in the shape of a truncated cone, which can effectively prevent the tool from colliding with the third button cover 5-3-1 during tool grinding (such as swinging the tool), thereby protecting the tool.

[0210] The outer side surface of the third button cover 5-3-1 is provided with a third anti-slip portion 5-3-2. For example, the third anti-slip portion 5-3-2 is a mesh anti-slip pattern, which is convenient for installing and removing the third knob 5-3.

[0211] A fourth anti-slip portion 5-3-3 is provided at the top of the third button cover 5-3-1. The fourth anti-slip portion 5-3-3 includes a plurality of annular anti-slip grooves. When the entire adjustable angle ruler needs to be placed vertically, for example, the top of the third button cover 5-3-1 is against the desktop (it can also be 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 desktop. The plurality of concentric annular anti-slip grooves of the fourth anti-slip portion 5-3-3 can maintain the same friction at any horizontal angle, achieve the same anti-slip effect, and are safer to use.

[0212] 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, and a first buffer portion 5-4-1 is provided in the reserved gap 5-4, such as a silicone cushion, to better prevent the sharpening rod 8-1 from colliding with the third button cover 5-3-1 and avoid noise. In this embodiment 8, the first buffer portion 5-4-1 fills the reserved gap 5-4, so that the sharpening rod 8-1 is flattened with the top of the sharpening bracket 5, eliminating the active gap of the sharpening rod 8-1, avoiding collision between the sharpening rod 8-1 and the third button cover 5-3-1, and avoiding noise.

[0213] In addition, a second buffer portion 5-4-2, such as a silicone cushion, may be provided between the connecting section A6-1 of the third connecting member 6 and the cone rod 8-3 to better prevent collision between the cone rod 8-3 and the third connecting member 6 and avoid noise.

[0214] The sharpening bracket 5 is provided with an open groove 5-1 for mounting the sharpening rod 8-1. The surface of the sharpening rod 8-1 corresponding to the opening 5-1-1 of the open groove 5-1 is the sharpening surface 8-1-1, and the tool is sharpened on the sharpening surface 8-1-1. The sharpening rod 8-1 located in the open groove 5-1 can also rotate by itself, so that different positions on the outer surface of the sharpening rod 8-1 have the opportunity to correspond to the opening 5-1-1 of the open groove 5-1, and can all be used to sharpen the tool, thereby maximizing the use of the outer surface of the sharpening rod 8-1, fully ensuring the working efficiency of the sharpening rod 8-1, effectively improving the utilization rate of the sharpening rod 8-1, and ensuring that the sharpening rod 8-1 provides more and best sharpening effects for tool sharpening.

[0215] The arc length of the cross section of the opening 5-1-1 is less than or equal to half of the circumference of the circle where the cross section of the opening groove 5-1 is located, which can ensure that the sharpening rod 8-1 is installed in the opening 5-1-1 and is not easy to fall off, and at the same time, the area of ​​the opening 5-1-1 (that is, the area of ​​the sharpening surface 8-1-1) can be as large as possible, which provides convenience for sharpening the tool on the sharpening surface 8-1-1 and avoids the edge of the opening groove 5-1 affecting the sharpening of the tool.

[0216] The outer side of the knife sharpening bracket 5 is also provided with cowhide 8-2 for sharpening the knife, such as two pieces of yellow cowhide 8-2, one with a polished surface and the other with a rough surface, which increases the usage scenarios of the knife sharpener. It can not only sharpen the knife, but also be used for polishing the knife.

[0217] In this embodiment 8, the cross-section of the knife sharpening bracket 5 is hexagonal, wherein cowhide 8-2 is respectively provided on two opposite sides (such as the upper side and the lower side), and open grooves 5-1 are respectively provided at two corners away from the cowhide 8-2 (such as the left end and the right end). The storage space inside the knife sharpening bracket 5 is five storage holes 5-2. For example, two of the storage holes 5-2 each receive a spare diamond round tube sharpening rod 8-1, and the other two storage holes 5-2 each receive a spare alumina polishing ceramic rod. Both the diamond round tube sharpening rod 8-1 and the alumina polishing ceramic rod can be installed in the open groove 5-1 to realize the corresponding tool sharpening function. The storage hole 5-2 located in the middle part of the cross section of the knife sharpening bracket 5 is a tapered rod storage hole 5-2-1, one end of which is connected to the third knob 5-3 (for example, the inner side wall of the tapered rod storage hole 5-2-1 corresponding to one end of the third knob 5-3 is provided with an internal thread matching the external thread of the third knob 5-3), and the other end of the tapered rod storage hole 5-2-1 is connected to the third connecting member 6.

[0218] The storage space is, for example, a plurality of storage holes 5-2, which are stored separately without interfering with each other to avoid touching each other and causing damage. 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 storage holes 5-2 correspond to the two ends of the knife sharpening bracket 5, so the third knob 5-3 and the third connecting member 6 respectively abut against the two ends of the knife sharpening rod 8-1 and / or the cone rod 8-3 in the storage hole 5-2.

[0219] The first bracket 1 is connected to one end of the handle 7. For example, one end (such as the top end) of the first connecting groove 1-13 of the first bracket 1 is connected to the third connecting member 6, and the other end (such as the bottom end) of the first connecting groove 1-13 is connected to the threaded sleeve 9. The threaded sleeve 9 is connected to one end (such as the top end) of the handle 7 through a bolt. At this time, the top of the handle 7 limits the bottom of the first angle adjustment knob 4, and cooperates with the first bracket 1 to limit the top of the first angle adjustment knob 4. When the first angle adjustment knob 4 rotates, the first angle adjustment knob 4 does not move in the axial direction, thereby ensuring the accuracy of the axial movement of the push tube 3 when the first angle adjustment knob 4 rotates.

[0220] The top of the first angle adjustment knob 4 abuts against the bottom of the first bracket 1, which can prevent the first angle adjustment knob 4 from shaking, reduce the shaking gap between the first angle adjustment knob 4 and the push tube 3, and make the axial movement of the push tube 3 always remain coaxial with the center of the handle or the axis). The first bracket 1 limits the top of the first angle adjustment knob 4, and the bottom of the first angle adjustment knob 4 abuts against the handle 7. The handle 7 limits the bottom of the first angle adjustment knob 4. When the first angle adjustment knob 4 rotates, the first angle adjustment knob 4 does not move in the axial direction. Accordingly, the first angle adjustment knob 4 drives the push tube 3 to achieve axial movement through a threaded connection.

[0221] The top of the handle 7 (or the fourth boss portion 7-8 of the handle) can also be used to abut against the push tube 3 to help limit the push tube 3 in the axial direction, that is, the bottom of the push tube 3 is axially limited by the handle 7 to prevent the user from forcibly over-rotating the first angle adjustment knob 4 and causing damage to the first protrusion 3-3.

[0222] The interior of the handle 7 is hollow, forming a fourth storage space 7-1 for storing the sharpening part. When sharpening is not needed, the sharpening bracket 5 can be removed from the first bracket 1, and then the sharpening part (i.e., the sharpening bracket 5 and the sharpening rod 8-1, the cone rod 8-3 and the cowhide 8-2 thereon) can be stored in the fourth storage space 7-1 inside the handle 7. The overall size of the sharpener is reduced, the appearance is more beautiful, and the overall storage of the sharpener is convenient (for example, into the user's tool box or pocket). It can also avoid accidental loss of the sharpening part and avoid damage to the sharpening part (especially the sharpening rod 8-1, the cone rod 8-3 and the cowhide 8-2) due to external reasons, such as accidental bumps.

[0223] The other end of the handle 7 is connected to the tail cover 7-2, and the tail cover 7-2 cooperates with the handle 7 to realize the storage of the sharpening part. The tail cover 7-2 is provided with a plurality of arrow-twisting teeth 7-2-7, and the arrow-twisting teeth 7-2-7 form a fourth hollow part 7-2-1 for twisting the arrow head. When the tail cover 7-2 is tightened on the handle 7, the fourth hollow part 7-2-1 is used to twist the arrow head, which is convenient for the disassembly and installation of the arrow head and the arrow in the field, and the arrow head and the arrow can be reused, thereby improving the utilization rate of the arrow head and the arrow.

[0224] Preferably, a fourth protrusion 7-2-8 is provided on the side of the twisting arrow tooth 7-2-7 facing the inside of the handle 7, which can prevent the grinding rod bracket 5 from shaking when it is stored in the handle 7 and avoid generating noise.

[0225] The other end of the handle 7 is provided with a fourth mounting hole 7-4 for mounting a hand rope (not shown in the attached figure). By mounting the hand rope on the handle 7, the sharpener can be conveniently carried, the sharpener can be prevented from being lost, and the sharpener can be prevented from accidentally falling and being damaged. A fifth mounting hole 7-2-2 is provided on the tail cover 7-2 at a position corresponding to the fourth mounting hole 7-4. The hand rope is placed outside the handle 7 after passing through the fifth mounting hole 7-2-2, which is convenient for using the hand rope. The fifth mounting hole 7-2-2 and the fourth hollow portion 7-2-1 are connected through a tortuous channel 7-2-3. One end of the hand rope is first connected to the fourth mounting hole 7-4, and then the other end of the hand rope is passed through the fourth hollow portion 7-2-1. Place it outside the handle 7, so that the installation is more convenient and efficient, and then the hand rope body is pushed into the fifth mounting hole 7-2-2 along the tortuous channel 7-2-3. The tortuous channel 7-2-3 can confine the hand rope body in the fifth mounting hole 7-2-2, and prevent the hand rope body from easily returning to the fourth hollow portion 7-2-1, and prevent the hand rope body from being cut by the arrow in the fourth hollow portion 7-2-1. For example, when the user uses the fourth hollow portion 7-2-1 of the tail cover 7-2 to twist the arrow, the arrow is embedded in the fourth hollow portion 7-2-1. If the hand rope body is in the fourth hollow portion 7-2-1, the arrow is bound to cut the hand rope body.

[0226] The tail cover 7-2 is provided with a fourth buckle 7-2-6, and the other end of the handle 7 is provided with a fourth perforation 7-7. The fourth buckle 7-2-6 and the fourth perforation 7-7 match to realize the detachable connection between the handle 7 and the tail cover 7-2. The user presses the fourth buckle 7-2-6 through the fourth perforation 7-7 to separate the fourth buckle 7-2-6 from the fourth perforation 7-7, which facilitates the separation of the tail cover 7-2 and the handle 7. For example, the tail cover 7-2 is provided with two groups of fourth buckles 7-2-6 and fourth perforations 7-7, which are arranged correspondingly on both sides of the tail cover 7-2, which is convenient to use and the connection between the handle 7 and the tail cover 7-2 is fastened.

[0227] The tail cover 7-2 is provided with a second positioning protrusion 7-2-4, such as an arc-shaped protrusion, and the other end of the handle 7 is provided with a second positioning groove 7-5, such as an arc-shaped groove, and the second positioning protrusion 7-2-4 and the second positioning groove 7-5 match each other. Before the tail cover 7-2 and the handle 7 are installed, the second positioning protrusion 7-2-4 and the second positioning groove 7-5 are aligned, and the installation angle of the handle 7 and the tail cover 7-2 can be predetermined, and the function of pre-positioning the handle 7 and the tail cover 7-2 is realized, and the handle 7 and the tail cover 7-2 are prevented from being mis-installed (that is, the handle 7 and the tail cover 7-2 are not aligned, and the tail cover 7-2 and the handle 7 cannot be installed), and the fourth mounting hole 7-4 and the fifth mounting hole 7-2-2 cannot be aligned after the handle 7 and the tail cover 7-2 are installed, so that the hand rope body is easily cut by the arrow. At the same time, after the tail cover 7-2 and the handle 7 are installed, the second positioning protrusion 7-2-4 and the second positioning groove 7-5 are clamped with each other, which can also prevent the tail cover 7-2 and the handle 7 from axial rotation.

[0228] A second limit block 7-6 is provided at the other end of the handle 7 (i.e., the outer side surface close to the bottom end), and a second limit groove 7-2-5 is provided on the inner wall of the tail cover 7-2. The second limit block 7-6 matches the second limit groove 7-2-5. When the handle 7 and the tail cover 7-2 are aligned and installed, the second limit block 7-6 is also synchronously embedded in the second limit groove 7-2-5, which can effectively prevent the tail cover 7-2 and the handle 7 from axial rotation.

[0229] The knife sharpener also includes a knife sharpening portion and a tapered rod 8-3. The tapered rod 8-3 is provided with a hook sharpening groove 8-3-1 for sharpening fish hooks. An extension section 8-3-2 is provided between the thicker end of the tapered rod 8-3 and the hook sharpening groove 8-3-1. After the tapered rod 8-3 is connected to the first bracket 1, part of the extension section 8-3-2 is located outside the first bracket 1. When sharpening fish hooks, the hook sharpening groove 8-3-1 should not be too close to the first bracket 1, because once the fish hook is hit by the first bracket 1, the fish hook cannot be effectively sharpened. Moreover, after the working part of the tapered rod 8-3 (such as the part used for sharpening the knife) is synchronously extended forward by the extension section 8-3-2, it is convenient for the tapered rod 8-3 to better sharpen the fish hook.

[0230] The thicker end of the tapered rod 8-3 is provided with a third external thread 8-3-3, and the third external thread 8-3-3 matches the third internal thread 9-1 of the threaded sleeve 9 or matches the fourth internal thread 1-13-2 in the first connecting groove 1-13, thereby realizing the connection between the tapered rod 8-3 and the first bracket 1, and facilitating the disassembly and assembly of the tapered rod 8-3 and the first bracket 1.

[0231] The inner wall of the handle 7 is also provided with a reinforcing rib 7-9, and the outer wall of the knife sharpening bracket 5 is provided with a third positioning inner recess 5-5. The reinforcing rib 7-9 matches the third positioning inner recess 5-5. The reinforcing rib 7-9 increases the strength of the handle 7 itself. Before the knife sharpening bracket 5 is stored in the handle, the reinforcing rib 7-9 is aligned with the third positioning inner recess 5-5, and the knife sharpening bracket 5 can be inserted into the handle 7 (i.e., the fourth storage space 7-1). After the knife sharpening bracket 5 is inserted into the handle 7, the reinforcing rib 7-9 is aligned with the third positioning inner recess 5-5 are offset, for example, six groups of reinforcing ribs 7-9 and the third positioning inner concave portion 5-5 can relatively fix the position of the knife sharpening bracket 5 in the handle 7, and the knife sharpening bracket 5 in the handle 7 will not shake accidentally, and at the same time, a gap is maintained between the knife sharpening bracket 5 and the inner side wall of the handle 7, so as to avoid friction or collision between the inner side wall of the handle 7 and the knife sharpening bracket 5 (especially the cowhide 8-2 and the knife sharpening rod 8-1 in the opening groove 5-1), thereby protecting the cowhide 8-2 and the knife sharpening rod 8-1 in the opening groove 5-1. In addition, the third positioning inner concave portion 5-5 can also prevent the knife from colliding with the knife sharpening bracket 5 when sharpening the knife.

[0232] The sharpening rod 8-1 can be a hollow rod to help reduce the overall weight of the sharpener and facilitate carrying.

[0233] The specific use of the knife sharpener in this embodiment 8 is to open the tail cover 7-2, take out the knife sharpening bracket 5 in the handle 7, select a suitable knife sharpening rod 8-1 to be installed in the opening groove 5-1, store the remaining knife sharpening rods 8-1 and the cone rod 8-3 in the knife sharpening bracket 5, and then align and connect the knife sharpening bracket 5 with the first bracket 1 (the first bracket 1 has been installed at the top of the handle 7), and raise the first inclined surface 2-1 of the angle gauge to a suitable inclined angle by rotating the first angle adjustment knob 4, and then grind the tool on the knife sharpening rod 8-1 using the first inclined surface 2-1. The cowhide 8-2 can also be used alone to polish the tool. When the cone rod 8-3 is needed, the knife sharpening bracket 5 is removed from the first bracket 1, and the third knob 5-3 is unscrewed from the top of the knife sharpening bracket 5, and the cone rod 8-3 is taken out from the cone rod storage hole 5-2-1. After the cone rod 8-3 is installed with the first bracket 1, the cone rod 8-3 can be used to grind fish hooks or knives. When the arrow is needed to be twisted, the handle 7 with the sharpening bracket 5 removed is connected to the tail cover 7-2, the arrow twisting teeth 7-2-7 on the tail cover 7-2 are inserted into the arrow, and the handle 7 is rotated to drive the arrow to rotate, so that the arrow and the arrow branch can be disassembled and assembled. When the sharpener is not needed, the sharpening bracket 5 (including the sharpening rod 8-1 and the cone rod 8-3) is stored in the handle 7, and the tail cover 7-2 is covered, and it can be carried around.

[0234] The inner side wall 7-7-1 of the handle bottom corresponding to the fourth through hole 7-7 is an arc surface, which can reduce the amount of engagement between the tail cover 7-2 (actually the fourth buckle 7-2-6) and the handle 7, making it easier to remove the tail cover 7-2.

[0235] See also Figure 53 to Figure 65 , specific embodiment 9, this embodiment 9 provides a knife sharpener, which includes an angle gauge with adjustable angle as described in the above embodiments, and the difference between this embodiment 9 and embodiment 8 is that a first knob 1-7 is provided radially on the first bracket 1 corresponding to the first connecting groove 1-13, and the connecting section B6-2 is provided with a radial third mounting hole 6-2-2 and a third axial hole 6-2-1 for mounting a metal insert 6-3. After the connecting section B6-2 is embedded in the first connecting groove 1-13, the third mounting hole 6-2-2 matches the first knob 1-7 to realize the connection between the third connecting member 6 and the first bracket 1.

[0236] 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 embedded in the sharpening bracket 5 (such as the bottom end of the cone rod receiving hole 5-2-1), the metal insert 6-3 is embedded in the third axial hole 6-2-1. The third axial hole 6-2-1 can extend into the connecting section A6-1 (such as connected to the third hollow portion 6-1-1). 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 sharpening bracket 5 (such as the inside of the bottom end of the cone rod receiving hole 5-2-1), thereby preventing the third connecting member 6 from falling off from the sharpening bracket 5. In addition, the strength of the third connecting member 6 (especially the connecting section B6-2) is also strengthened, and the connecting section B6-2 is not easy to break accidentally.

[0237] The first guide grooves 1-5 and the first knobs 1-7 are opposite to each other and correspond to the cowhide 8-2 on the knife sharpening bracket 5 respectively (ie, the first guide groove 1-5 corresponds to one cowhide 8-2 for sharpening the knife, and the first knob 1-7 corresponds to another cowhide 8-2 for sharpening the knife).

[0238] The outer side surface of the connecting section B6-2 is provided with a positioning surface B6-2-3, and the inner side wall of the first connecting groove 1-13 is provided with a positioning surface A1-13-1. The positioning surface A1-13-1 and the positioning surface B6-2-3 match each other to prevent wrong installation. That is, before the connecting section B6-2 is embedded in the first connecting groove 1-13, the positioning surface B6-2-3 of the connecting section B6-2 corresponds to the positioning surface A1-13-1 of the first connecting groove 1-13, and then embedded. This ensures that after the two are installed, the installation position of the sharpening bracket 5 and the first bracket 1 is accurate (that is, the angle gauge corresponds to the corresponding sharpening rod 8-1 on the sharpening part), thereby improving assembly efficiency. At the same time, the positioning surface A1-13-1 and the positioning surface B6-2-3 can also prevent the connecting section B6-2 from rotating, play a role in stopping rotation, and ensure that during the use of the sharpener, the angle gauge always corresponds to the corresponding sharpening rod 8-1 on the sharpening part.

[0239] The first knob 1-7 includes a first knob cover 1-7-3 and a screw rod 1-7-4, one end of the screw rod 1-7-4 is connected to the first knob cover 1-7-3, a second external thread 1-7-1 is provided on the outer wall of the first knob cover 1-7-3, a first through hole 1-11 is provided on the first bracket 1 for installing the first knob 1-7, and a second internal thread 1-11-1 is provided on the inner wall of the first through hole 1-11. At this time, the second external thread 1-7-1 and the second internal thread 1-11-1 match each other, and by rotating the first knob 1-7, the first knob 1-7 passes through the first through hole 1-11 and is embedded in the third mounting hole. Mounting hole 6-2-2, after tightening the first knob 1-7, the first knob 1-7 and the third mounting hole 6-2-2 work together to limit the axial movement of the third connecting member 6 (i.e., axial limitation), thereby realizing the connection between the first bracket 1 and the sharpening bracket 5. In addition, after tightening the first knob 1-7, the first knob 1-7 cooperates with the inner wall of the first connecting groove 1-13 to clamp the connecting segment B6-2, thereby fixing the position of the connecting segment B6-2 in the radial direction and avoiding radial shaking of the connecting segment B6-2. That is to say, the axial and radial limitations of the connecting segment B6-2 are realized by the first knob 1-7. In addition, the screw rod 1-7-4 between the second external thread 1-7-1 and the first button cover 1-7-3 is also provided with a second limiting portion 1-7-2. The second limiting portion 1-7-2, the screw rod 1-7-4 and the first button cover 1-7-3 realize a pattern of large ends and small middle. A limiting structure is formed between the second limiting portion 1-7-2 and the opening of the first through hole 1-11. The first button cover 1-7-3 is located outside the first bracket 1, and the second limiting portion 1-7-2 is located inside the first bracket 1 (i.e., inside the first through hole 1-11). No matter how the first knob 1-7 is rotated, it will not detach from the first through hole 1-11, thereby preventing the first knob 1-7 from being lost. The outer side of the first button cover 1-7-3 is provided with a second anti-slip portion 1-7-5. For example, the second anti-slip portion 1-7-5 adopts a grid anti-slip pattern to facilitate better tightening or loosening of the first knob 1-7. When a limit is formed between the second limit portion 1-7-2 and the opening portion of the first through hole 1-11, the first knob 1-7 can no longer be pulled out. At this time, it can also effectively indicate that the first knob 1-7 has completely withdrawn from the third mounting hole of the third connecting member 6, and the knife sharpening bracket 5 can be disassembled from the first bracket 1.

[0240] The top of the first bracket 1 is also provided with a first limiting groove 1-10, and the connection between the connecting section A6-1 and the connecting section B6-2 is provided with a third limiting protrusion 6-4 for resisting the sharpening rod 8-1 and / or the cone rod 8-3 in the storage hole 5-2. The third limiting protrusion 6-4 matches the first limiting groove 1-10, that is, after the first bracket 1 is installed with the third connecting member 6, the third limiting protrusion 6-4 is embedded in the first limiting groove 1-10, which can effectively prevent the third connecting member 6 from rotating, fix the angle of the third connecting member 6, and finally ensure that the sharpening rod 8-1 of the sharpening part can always correspond to the first inclined surface 2-1 of the angle gauge. At the same time, the third limiting protrusion 6-4 can also be used to resist the sharpening rod 8-1 and / or the cone rod 8-3 in the storage hole 5-2, to prevent the sharpening rod 8-1 and / or the cone rod 8-3 from sliding out from the bottom end of the storage hole 5-2. In addition, the third limiting protrusion 6-4 does not completely cover the end of the receiving hole 5-2, which makes it easy for the user to observe whether the sharpening rod 8-1 and / or the cone rod 8-3 is installed in the corresponding receiving hole 5-2.

[0241] The third connecting member 6 can be made of metal.

[0242] The connection between the connection section A6-1 and the connection section B6-2 of the third connecting member 6 is provided with a third buffer portion 6-6, such as a silicone buffer pad, for resisting the sharpening rod 8-1, so as to better prevent the sharpening rod 8-1 from colliding with the third connecting member 6 and avoid noise. At this time, the third knob 5-3 can be directly pressed onto the sharpening rod 8-1 to tighten the sharpening rod 8-1, and the third knob 5-3 is not pressed onto the sharpening bracket 5, so that the sharpening rod 8-1 also has no movable gap to avoid noise.

[0243] 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. During the installation process of the third connecting member 6 and the knife sharpening bracket 5, the third hollow portion 6-1-1 is pressed, and the connecting section A6-1 can be better embedded in the knife sharpening bracket 5 (such as the cone rod storage hole 5-2-1). After the connecting section A6-1 is embedded in the knife sharpening bracket 5, the connecting section A6-1 utilizes its own elasticity, and the third hollow portion 6-1-1 restores its shape. The third serrated portion 6-1-2 increases the friction between the connecting section A6-1 and the inner side wall of the knife sharpening bracket 5 (such as the cone rod storage hole 5-2-1), thereby enhancing the connection strength between the third connecting member 6 and the knife sharpening bracket 5.

[0244] See also Fig.66, specific embodiment 10, this embodiment 10 provides a knife sharpener, which includes an angle gauge with adjustable angle as described in the above embodiment, this embodiment 9 is different from the above embodiment in that the third connecting member 6 can be made of metal, the connecting section A6-1 of the third connecting member 6 is a circular structure as a whole, and the outer side surface of the connecting section A6-1 is provided with an anti-slip tooth shape 6-1-3, when the connecting section A6-1 is embedded in the knife sharpening bracket 5 (such as the cone rod storage hole 5-2-1), the anti-slip tooth shape 6-1-3 is fixed to the inside of the knife sharpening bracket 5 (such as the cone rod storage hole 5-2-1) by riveting to avoid slipping between the third connecting member 6 and the knife sharpening bracket 5.
