[0025] Please see Figure 1-9 This invention provides a knife sharpener adaptable to various types of cutting tools, comprising: The housing 1 has a housing opening 11 extending through its side wall; A sharpening assembly 2 is disposed within the housing 1. The sharpening assembly 2 includes a roller 21 rotatably disposed within the housing 1. The edge of the roller 21 is provided with a plurality of sharpening holes 213 along the circumferential direction. The plurality of sharpening holes 213 are all disposed through the roller 21 along the axial direction. A sharpening element 22 is disposed within each sharpening hole 213. An adaptive structure 23 is provided inside the grinding mouth 213 so that when the tool is being ground, the grinding member 22 can automatically fit against the side wall of the tool being ground. Rotating component 3 is used to drive the roller 21 to rotate so as to switch different grinding blades 213 corresponding to the opening 11 of the housing.

[0026] In this embodiment, a roller 21 is provided inside the housing 1, and a plurality of grinding mouths 213 are provided in the circumferential direction of the roller 21. The grinding element 22 is provided in the grinding mouth 213. In use, the blade is placed directly in the grinding mouth 213 and moved repeatedly. During the repeated movement of the blade, the adaptive structure 23 can push the grinding element 22 to fit against the side wall of the blade, so that the grinding element 22 can always keep in contact with the side wall of the blade during the grinding process, thereby achieving the grinding of the blade. It is not necessary to manually keep the blade and the grinding element 22 in contact, thereby improving the grinding efficiency and making it very convenient to use.

[0027] In one embodiment, a locking component 4 is also included, which is used to restrict the rolling of the roller 21 so that the grinding edge 213 is fixedly aligned with the housing opening 11.

[0028] Driven by the rotating component 3, different grinding edges 213 can be switched to correspond with the housing opening 11 as needed, thereby enabling the corresponding grinding edges 213 to be used for grinding the tools. The locking component 4 is used to lock the roller 21, so that the roller 21 can be fixed during use, restricting the rotation of the roller 21. When it is necessary to switch between different grinding edges 213, the locking component 4 is used to release the lock on the roller 21, allowing it to rotate under the drive of the rotating component 3.

[0029] like Figure 2 As shown, the roller 21 in this embodiment is composed of a left roller body 211 and a right roller body 212, which are fixed together by a number of screws to form the roller 21. The inner walls of both the left roller body 211 and the right roller body 212 are provided with a number of protruding ridges. These ridges not only enhance the strength of the left roller body 211 and the right roller body 212, but also, through their cooperation, create installation spaces, facilitating the installation of certain structures.

[0030] In this embodiment, three grinding edges 213 are provided in the circumferential direction of the roller 21.

[0031] In a further embodiment, the grinding member 22 is disposed on one side of the grinding mouth 213, and the grinding member 22 is disposed along the length direction of the grinding mouth 213.

[0032] The grinding tool 22 can be disposed on both sides of the grinding opening 213 in the width direction. In this embodiment, the grinding opening 213 is provided with the grinding tool 22 on only one side, and the grinding tool 22 on this side is disposed along the length direction of the grinding opening 213.

[0033] In one embodiment, such as Figure 3 , Figure 4 , Figure 5 As shown, a mounting groove 214 is provided on one side wall of the grinding mouth 213, the grinding tool 22 is movably disposed in the mounting groove 214, and an adaptive structure 23 is disposed in the mounting groove 214. The adaptive structure 23 pushes the grinding tool 22 to move to the other side of the grinding mouth 213.

[0034] In this embodiment, the mounting groove 214 is disposed on one side of the grinding mouth 213, and the grinding member 22 is movably disposed within the mounting groove 214. Under the action of the adaptive structure 23, the grinding member 22 moves to the other side of the grinding mouth 213. When the blade is inserted into the grinding mouth 213, the grinding member 22 automatically maintains a close contact with the blade under the action of the adaptive structure 23, so that the grinding member 22 continuously grinds the blade during the movement of the blade.

[0035] In a further embodiment, the adaptive structure 23 includes a movable frame 231 and a first pusher 232; the grinding tool 22 is fixedly mounted on the movable frame 231, and one end of the first pusher 232 abuts against the movable frame 231, while the other end abuts against the roller 21. In this embodiment, the other end of the first pusher 232 abuts against the bottom of the mounting groove 214.

[0036] In this embodiment, the pushing member is formed by the cooperation of the movable frame 231 and the first pushing member 232. The sharpening member 22 is fixedly mounted on the movable frame 231. The movable frame 231 serves as a support member for mounting the sharpening member 22. Both ends of the first pushing member 232 abut against the bottom of the movable frame 231 and the mounting groove 214, respectively, enabling the movable frame 231 to move towards the other side of the sharpening edge 213.

[0037] In this embodiment, as Figure 5 As shown, the specific structure of the movable frame 231 includes a support plate 2313. The grinding tool 22 is fixedly arranged on one side of the support plate 2313 in the thickness direction, and a first leg 2311 and a second leg 2312 perpendicular to it are arranged on the other side. The first leg 2311 and the second leg 2312 are arranged along the length direction of the support plate 2313. A first limiting block 2314 is provided on the side of the first support leg 2311 away from the second support leg 2312, and a second limiting block 2315 is provided on the side of the second support leg 2312 away from the first support leg 2311. The bottom of the mounting groove 214 is provided with a first through hole 2141 and a second through hole 2142; The first support leg 2311 is slidably disposed in the first through hole 2141, and the second support leg 2312 is slidably disposed in the second through hole 2142; The first limiting block 2314 restricts the first support leg 2311 from sliding out of the first through hole 2141; The second limiting block 2315 restricts the second leg 2312 from sliding out of the second through hole 2142.

[0038] In this embodiment, as Figure 6 As shown, a right U-shaped groove 2123 is formed on the inner sidewall of the right disc 212 near the grinding edge 213. A first right protrusion 2121 and a second right protrusion 2122 are respectively provided on the outer sides of both ends of the right U-shaped groove 2123 along its length. The first right protrusion 2121 is located away from the axis of the roller disc 21, and the second right protrusion 2122 is located near the axis of the roller disc 21. A first right gap 2124 is provided between the first right protrusion 2121 and the outer sidewall of the right U-shaped groove 2123, while a second right gap 2125 is provided between the second right protrusion 2122 and the outer sidewall of the right U-shaped groove 2123.

[0039] After the left disc 211 and the right disc 212 are engaged, the first right protrusion 2121 and the second right protrusion 2122 engage accordingly, and the right U-shaped groove 2123 and the left disc 211 engage to form the mounting groove 214, allowing the grinding tool 22 to be movably disposed within the mounting groove 214. The first right gap 2124 engages with the left disc 211 to form the first through hole 2141, and the left disc 211 and the second right gap 2125 engage to form the second through hole 2142.

[0040] In this embodiment, the first support leg 2311 and the second support leg 2312 of the movable frame 231 are slidably disposed in the first through hole 2141 and the second through hole 2142, so that when the blade is placed in the sharpening mouth 213, the sharpening member 22 on the movable frame 231 can keep in contact with the blade under the action of the first pushing member 232, and the blade is sharpened during the movement.

[0041] In this embodiment, the first pusher 232 is a first spring.

[0042] The opening width of the grinding edge 213 gradually increases towards the axis away from the roller 21.

[0043] In this embodiment, the grinding edge 213 is V-shaped, and the opening direction of the grinding edge 213 is opposite to the axis of the roller 21. This facilitates the insertion of the cutting edge of the tool into the grinding edge 213.

[0044] In one embodiment, please refer again Figure 3 The rotating assembly 3 includes an adjustment knob 31 disposed on the outside of the housing 1 and a drive gear 32 coaxially connected to the adjustment knob 31; The outer side of the roller 21 is coaxially connected to the roller gear 34; Both the roller gear 34 and the driving gear 32 mesh with the transmission gear 33.

[0045] In this embodiment, the drive gear 32, the roller gear 34 and the transmission gear 33 cooperate with each other so that by rotating the adjustment knob 31, the roller gear 34 can be rotated, thereby controlling the rotation angle of the roller 21.

[0046] In this embodiment, the roller gear 34 is integrally formed with the left disc body 211. The outer diameter of the adjustment knob 31 is larger than the outer diameter of the drive gear 32, which makes it easier to rotate the drive gear 32 and adjust the angle of the roller 21.

[0047] In addition, such as Figure 7 and Figure 8 As shown, in this embodiment, the drive gear 32 and the adjustment knob 31 are integrally formed. A mounting hole 12 is formed by an inward recess in the outer wall of the housing 1, and a mounting shaft 121 is provided at the center of the mounting hole 12. An adjustment hole 311 is provided at the center of the drive gear 32 and the adjustment knob 31, and the adjustment hole 311 is fitted onto the mounting shaft 121, allowing the adjustment knob 31 and the drive gear 32 to rotate synchronously around the mounting shaft 121. A sidewall opening 122 is provided through the sidewall of the mounting hole 12, through which the drive gear 32 meshes with the transmission gear 33.

[0048] In one embodiment, such as Figure 9 As shown, the locking assembly 4 includes a locking rod 41 that rotates around a center; a second pusher 42 and a pressing member 43 are respectively provided on both sides of one end of the locking rod 41. The second pusher 42 pushes one end of the locking rod 41 to rotate around the rotation center, so that the other end of the locking rod 41 abuts against the roller 21, thereby restricting the rotation of the roller 21; The pressing element 43 is disposed through the side wall of the housing 1.

[0049] In this embodiment, a locking through hole 411 is provided at the center of the locking rod 41, and a locking shaft 13 is fixedly provided inside the housing 1. The locking through hole 411 is rotatably provided on the locking shaft 13, so that the locking rod 41 can rotate around the locking shaft 13.

[0050] One end of the locking rod 41 is used to cooperate with the roller 21, allowing it to be inserted into the roller 21 to lock the roller 21 and restrict its rotation. The pressing member 43 and the second pushing member 42 are respectively provided on both sides of the other end of the locking rod 41. Under the action of the second pushing member 42, the end of the locking rod 41 remains in contact with the roller 21. By pressing down the pressing member 43 to overcome the pushing force of the second pushing member 42, the locking rod 41 can be released from locking the roller 21.

[0051] In a further embodiment, the locking rod 41 is provided with a locking protrusion 412 at the end near the roller 21, and the roller 21 is provided with a plurality of locking grooves 215 that cooperate with the locking protrusion 412. When the locking protrusion 412 engages with one of the locking grooves 215, the corresponding grinding edge 213 corresponds to the housing opening 11.

[0052] Under the action of the second pushing member 42, the locking protrusion 412 can be embedded in the locking groove 215, thereby improving the stability of the locking rod 41 locking the roller 21. The number of locking grooves 215 corresponds to the number of grinding edges 213 on the roller 21, so that when the locking protrusion 412 cooperates with the corresponding locking groove 215, a corresponding grinding edge 213 can correspond to the housing opening 11, realizing that different grinding edges 213 correspond to the housing opening 11.

[0053] In further embodiments, please refer again. Figure 1 A handle 14 is provided at one end of the top of the housing 1 along its length, and the housing opening 11 is provided at the other end; A support portion 15 is provided at the bottom of the housing 1.

[0054] In this embodiment, a handle portion 14 and a housing opening 11 are respectively provided at both ends of the top of the housing 1 along its length, while a support portion 15 is provided at the bottom of the housing 1. In use, the handle portion 14 allows for easy gripping with one hand, while the other hand picks up the blade and sharpens it within the sharpening groove 213 inside the housing opening 11. During sharpening, the handle portion 14 applies pressure to the support portion 15, ensuring the support portion 15 is stably supported on the table, thus improving the convenience and stability of the sharpening process.

[0055] The support portion 15 is provided with an anti-slip pad, which may be made of silicone material.

[0056] In another embodiment, a pressing member 43 is also provided on the top of the housing 1. The pressing member 43 is disposed between the handle portion 14 and the housing opening 11, and is located on the side closer to the handle portion 14. This allows the pressing member 43 to be pressed simultaneously with the thumb when the handle portion 14 is gripped, thereby releasing the lock of the roller 21 and facilitating its rotation.

[0057] In addition, such as Figure 1 As shown, the housing opening 11 is located on the upper right side, while the handle 14 is located on the upper left side. The pressing member 43 is positioned between the housing opening 11 and the handle 14, and the adjusting knob 31 faces the paper. This allows the left hand, as the non-dominant hand, to grip the handle 14 and release the locking of the roller 21 by simultaneously pressing down on the pressing member 43 with the left thumb. The right hand, as the dominant hand, can hold the blade to sharpen it or rotate the adjusting knob 31 to change the sharpening tip 213, which is more ergonomic.

[0058] This application provides a knife sharpener that is compatible with various types of knives. When in use, the user rotates the adjustment knob 31 located on the outside of the housing 1, and the drive gear 32 coaxially connected to it rotates accordingly. The drive gear 32 drives the roller gear 34 to rotate through the transmission gear 33, thereby causing the roller 21 to roll and rotate the sharpening rim 213 of the required size to a position directly opposite the opening 11 of the housing.

[0059] After the roller 21 stops rotating, the locking rod 41 rotates around the locking shaft 13 under the action of the second pushing member 42, causing the locking protrusion 412 at the end of the locking rod 41 to embed into the corresponding locking groove 215 on the roller 21, restricting the roller 21 from continuing to roll, and keeping the grinding edge 213 corresponding and fixed to the housing opening 11. When it is necessary to switch the grinding edge 213, the user presses the pressing member 43 that penetrates the side wall of the housing 1, overcoming the elastic force of the second pushing member 42, causing the locking rod 41 to rotate in the opposite direction, and the locking protrusion 412 to disengage from the locking groove 215, releasing the locking state.

[0060] The sharpening edge 213 is V-shaped, with the opening facing outwards and gradually widening away from the axis of the roller 21, facilitating blade insertion. A movable frame 231 is disposed within the mounting groove 214 on one side of the sharpening edge 213. The sharpening component 22 is fixed to one side of the support plate 2313 of the movable frame 231, and the other side has a first support leg 2311 and a second support leg 2312, which slide through the first through hole 2141 and the second through hole 2142, respectively. A first pushing member 232 abuts against the bottom of the mounting groove 214 and the movable frame 231. After the blade is inserted into the sharpening edge 213, it pushes the sharpening component 22 and the movable frame 231 towards the bottom of the mounting groove 214. The first pushing member 232 is compressed and generates a reverse elastic force, ensuring that the sharpening component 22 remains in close contact with the blade surface. The user repeatedly pulls the blade through the opening 11 of the housing, and the grinding element 22 continuously acts on the blade along the length of the grinding mouth 213 to grind the blade.

[0061] Compared with the prior art, this application has the following advantages: (1) Strong adaptability: The roller 21 is equipped with multiple grinding mouths 213 of different sizes, which can be adapted to various types of cutting tools to meet different grinding needs.

[0062] (2) Automatic grinding fit: Under the action of the adaptive structure 23, the grinding part 22 automatically keeps in contact with the blade, ensuring that the grinding process is continuous and uniform, and improving grinding efficiency.

[0063] (3) Convenient and labor-saving operation: The outer diameter of the adjustment knob 31 is larger than that of the drive gear 32, which has a labor-saving effect; the handle 14 and the pressing part 43 cooperate to complete the locking and unlocking and gripping with one hand, which is in line with the usage habits of most people.

[0064] (4) Stable and safe to use: The locking component 4 ensures that the roller 21 is securely fixed during operation, and the bottom support 15 is equipped with an anti-slip pad to improve the stability and safety of the sharpening process.

[0065] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and these modifications or substitutions should all be covered within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
