Description

Technical Field

[0001] This utility model relates to the field of kitchen utensils, specifically to a knife holder. Background Technology

[0002] Traditionally, the knife holder and sharpener are two separate components, stored separately. This often leads to users not being able to find the sharpener when sharpening is needed, causing significant inconvenience. Related technologies have proposed solutions that place the sharpener directly in the knife holder's slot. However, this still involves sharpening the knife every time it's retrieved or placed, easily damaging previously sharp or new knives. Utility Model Content

[0003] Therefore, the purpose of this utility model is to provide a tool holder that is equipped with a sharpening module, which makes sharpening convenient. When sharpening is not required, the sharpening element can be hidden, thereby preventing damage to tools that do not require sharpening from being sharpened.

[0004] One embodiment of the present invention provides a tool holder, which includes: a tool holder body with a tool insertion slot; and a sharpening module disposed on the tool holder body. The sharpening module includes an adjusting member and a sharpening element. The adjusting member can adjust the sharpening element to extend into the tool insertion slot, and the adjusting member can also adjust the sharpening element to exit the tool insertion slot.

[0005] The tool holder provided in this embodiment includes a tool holder body and a sharpening module. When sharpening is needed, the sharpening element is inserted into the sharpening slot for sharpening. The tool is automatically sharpened as it moves in and out of the slot, making sharpening convenient. When sharpening is not needed, the sharpening element can be adjusted out of the slot using an adjusting mechanism, preventing damage to already sharp tools or new tools due to sharpening. This facilitates sharpening while preventing over-sharpening or accidental sharpening.

[0006] In some embodiments, a grinding edge is provided at one end of the insert groove along its length, and a grinding element can extend into the insert groove through the grinding edge.

[0007] In these embodiments, the sharpening element is inserted into one end of the insert slot along its length. After the tool is inserted into the insert slot, the cutting edge will be close to the sharpening element, which facilitates the sharpening of the cutting edge during the process of the tool entering and exiting the insert slot, making sharpening convenient.

[0008] In some embodiments, the adjusting element is a knob, a push button, or a lever. It has a simple structure, is easy to operate, and allows the user to adjust the position of the sharpening element using the adjusting element.

[0009] In some embodiments, the adjustment element is a knob, and the sharpening module further includes a transmission component that can convert the rotational motion of the knob into linear motion that drives the sharpening element to move.

[0010] In these embodiments, the adjusting element is a knob, which is easy to operate. Furthermore, the use of a transmission assembly to convert the rotary motion of the knob into linear motion that drives the sharpening element facilitates accurate adjustment of the sharpening element's position.

[0011] In some embodiments, the transmission assembly includes: an elastic member for applying a force to the grinding element to retract from the insert slot; and a telescopic member disposed between the grinding element and the knob, the telescopic member having a first guide rail and the knob having a second guide rail cooperating with the first guide rail; wherein, during the rotation of the knob in a first direction, the first guide rail moves uphill along the second guide rail, the telescopic member moves away from the knob and pushes the grinding element into the insert slot, and during the rotation of the knob in a second direction, the first guide rail moves downhill along the second guide rail, and the telescopic member and the grinding element can be reset under the elastic force of the elastic member.

[0012] In these embodiments, when sharpening is needed, the knob can be rotated in a first direction. During this process, the first guide rail on the knob moves uphill along the second guide rail, which pushes the telescopic component away from the knob. This causes the telescopic component to push the sharpening element into the tool slot, moving the sharpening element to the sharpening position. When sharpening is not needed, the knob can be rotated in the opposite direction, causing the first guide rail to move downhill along the second guide rail. This allows the telescopic component and the sharpening element to approach the knob under the elastic force of the elastic component until the sharpening element resets and moves to the hidden position. This transmission method has a simple structure, is easy to manufacture, and has high reliability. Moreover, after the knob is rotated to its position in the first direction, even if the sharpening element rubs against the tool, the backward linear motion is unlikely to cause the knob to rotate. Since the knob does not rotate, the sharpening element will not retract, ensuring the sharpening effect.

[0013] In some embodiments, the sharpening module further includes: a sharpening base, disposed on the sharpening base body, the sharpening base having a clearance opening, the sharpening element being disposed within the sharpening base corresponding to the position of the clearance opening, and an elastic member supporting the sharpening base and the sharpening element; and a telescopic member bracket, disposed on the sharpening base, the telescopic member bracket having a through hole, the telescopic member passing through the through hole and abutting against the sharpening element and being able to move along the through hole.

[0014] In these embodiments, the sharpening element, adjusting component, and transmission assembly are all directly or indirectly mounted on the sharpening holder, making the sharpening module a single unit. Compared to the sharpening module's components being separately assembled on the holder body, this eliminates the need for a complex mounting structure and installation space on the holder body, simplifying manufacturing. Furthermore, a telescopic bracket is provided within the sharpening holder, allowing the telescopic component to move along its through-hole, ensuring accurate movement of the sharpening element.

[0015] In some embodiments, the transmission assembly further includes an elastic support member supported between the telescopic member bracket and the telescopic member, the elastic support member being used to press the telescopic member against the knob. The design of the elastic support member facilitates the repositioning of the telescopic member and ensures that the telescopic member always remains in contact with the knob, thereby ensuring that rotating the knob can accurately move the telescopic member.

[0016] In some embodiments, the telescopic bracket is provided with a first stop, and the end face of the knob facing the telescopic member is provided with a second stop. The knob can be rotated in a first direction until the first stop and the second stop abut against each other. The design of the first stop and the second stop is beneficial to the user in knowing whether the knob has been rotated to the correct position when rotating it, and also ensures that the grinding element is fully extended when the knob is fully rotated to the correct position.

[0017] In some embodiments, the telescopic bracket is provided with a telescopic protrusion on the end face of the knob, and the knob is provided with a ring-shaped wave-shaped guide rail on the end face of the telescopic component. The telescopic protrusion abuts against the wave-shaped guide rail, and the telescopic protrusion expands and contracts along the wave-shaped guide rail during the rotation of the knob.

[0018] In these embodiments, rotating the knob causes the wave-shaped track to rotate, thereby repeatedly squeezing the retractable protrusions and causing them to continuously expand and contract. This increases the resistance to rotating the knob, and the retractable protrusions also make a clicking sound when they collide with the wave-shaped track, which can enhance the user experience of rotating the knob.

[0019] In some embodiments, the adjustment element is a push button, and the sharpening module further includes a ratchet mechanism and a spring. The two ends of the ratchet mechanism are respectively connected to the push button and the sharpening element, and the spring is used to apply a force to the ratchet mechanism to move in the direction of the push button.

[0020] In these embodiments, the adjustment element is a push button, which is easy to operate. Moreover, the push button is combined with a ratchet mechanism, so that when pressed once, the sharpening element extends into the tool slot, and when pressed a second time, the sharpening element retracts from the tool slot, which is beneficial for accurately controlling the sharpening element to the designated position.

[0021] In some embodiments, the adjusting element is a lever, and the lever and the sharpening element are integrated into one unit. Moving the lever moves the sharpening element. The sharpening module has few parts, a simple structure, is easy to manufacture, and is inexpensive. Furthermore, the sharpening element's movement can be controlled simply by reciprocating the lever, making operation convenient.

[0022] In some embodiments, a recess is provided on the outer surface of the tool holder body, and the grinding module is embedded in the recess. The tool holder has good overall integrity and a good appearance.

[0023] In some embodiments, the sharpening module is detachably connected to the tool holder body. This facilitates the replacement of the sharpening module, allowing for the use of new sharpening elements to sharpen the tool and ensuring effective sharpening.

[0024] Other aspects and / or advantages of the present invention will be set forth in part in the description which follows, and in part will be clear from the description or may be learned by practice of the present invention. Attached Figure Description

[0059] The following will combine Figures 1 to 12 This invention introduces a tool holder provided by an embodiment of the present invention.

[0060] like Figure 1 and Figure 2 As shown, one embodiment of the present invention provides a tool holder, which includes: a tool holder body 10, on which a tool insertion groove 110 is provided; and a sharpening module 20, which is disposed on the tool holder body 10. The sharpening module 20 includes an adjusting member 210 and a sharpening element 220. The adjusting member 210 can adjust the sharpening element 220 to extend into the tool insertion groove 110, and the adjusting member 210 can also adjust the sharpening element 220 to exit the tool insertion groove 110.

[0061] The tool holder provided in this embodiment includes a tool holder body 10 and a sharpening module 20. When sharpening is needed, the sharpening element 220 is inserted into the sharpening groove for sharpening. The tool 30 is automatically sharpened as it moves in and out of the insertion groove 110, making sharpening convenient. When sharpening is not needed, the sharpening element 220 can be adjusted out of the insertion groove 110 using the adjusting member 210, which can prevent damage to the originally sharp tool 30 or a new tool 30 due to sharpening. This facilitates sharpening while preventing over-sharpening or accidental sharpening.

[0062] Furthermore, in some embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, a sharpening port 120 is provided at one end of the blade insertion slot 110 along its length, and a sharpening element 220 can extend into the blade insertion slot 110 through the sharpening port 120. When the sharpening element 220 is extended into one end of the blade insertion slot 110 along its length, the blade will be close to the sharpening element 220 after the tool 30 is inserted into the blade insertion slot 110, which facilitates the sharpening of the blade during the process of the tool 30 entering and exiting the blade insertion slot 110, making sharpening convenient.

[0063] Figure 2 A schematic diagram shows the sharpening element 220 extending into the tool slot 110. Figure 3 A schematic diagram is shown showing the sharpening element 220 exiting the tool holder slot 110. (See diagram below.) Figure 2As shown, the sharpening element 220 has a scissor-type opening 221 that extends into the insert groove 110 and is close to the cutting edge of the tool 30. During the process of the tool 30 entering and exiting the insert groove 110, the cutting edge can be sharpened using the scissor-type opening 221.

[0064] Furthermore, in some embodiments, the adjusting element 210 is a knob, a push button, or a lever. This design is simple in structure, easy to operate, and allows the user to adjust the position of the sharpening element 220 via the adjusting element 210.

[0065] Of course, the adjusting element 210, as a trigger for adjusting the position of the sharpening element 220, is not limited to the examples described above. The adjusting element 210 can also be an electronic control panel, a voice control module, etc., which controls the sharpening element 220 to move to a designated position by receiving user pressing or voice commands. Anything that ultimately adjusts the sharpening element 220 to the designated position is acceptable, and will not be detailed here. Furthermore, to ensure that the user can ultimately control the action of the sharpening element 220 after operating the adjusting element 210, the adjusting element 210 can be directly connected to the sharpening element 220, or it can transmit power through a transmission assembly.

[0066] Regarding the specific structure of the sharpening module 20, in some embodiments, the adjusting element 210 is a knob, and the sharpening module 20 also includes a transmission component that can convert the rotational motion of the knob into linear motion that drives the sharpening element 220 to move.

[0067] In these embodiments, the adjusting member 210 is a knob, which is easy to operate. In addition, the transmission assembly converts the rotary motion of the knob into linear motion that drives the sharpening element 220, which helps the adjusting member 210 to accurately adjust the position of the sharpening element 220.

[0068] Furthermore, such as Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the transmission assembly includes: an elastic member 230 for applying a force to the sharpening element 220 to retract from the insert groove 110; and a telescopic member 240 disposed between the sharpening element 220 and the knob. The telescopic member 240 is provided with a first guide rail 241, and the knob is provided with a second guide rail 211 that cooperates with the first guide rail. During the rotation of the knob in a first direction, the first guide rail moves uphill along the second guide rail 211, and the telescopic member 240 moves away from the knob and pushes the sharpening element 220 into the insert groove 110. During the rotation of the knob in a second direction, the first guide rail moves downhill along the second guide rail 211, and the telescopic member 240 and the sharpening element 220 can be reset under the elastic force of the elastic member 230.

[0069] When sharpening is needed, the knob can be rotated in the first direction. During this process, the first guide rail on the knob moves uphill along the second guide rail 211, which pushes the telescopic member 240 away from the knob. This causes the telescopic member 240 to push the sharpening element 220 into the tool slot 110, moving the sharpening element 220 to the sharpening position. When sharpening is not needed, the knob can be rotated in the opposite direction, causing the first guide rail to move downhill along the second guide rail 211. This allows the telescopic member 240 and the sharpening element 220 to approach the knob under the elastic force of the elastic member 230 until the sharpening element 220 returns to its original position and moves to the hidden position. This transmission method has a simple structure, is easy to manufacture, and has high reliability. Moreover, after the knob is rotated to its position in the first direction, even if the sharpening element 220 rubs against the tool 30, the backward linear motion is unlikely to cause the knob to rotate. Since the knob does not rotate, the sharpening element 220 will not retract, ensuring the sharpening effect.

[0070] As an example, such as Figure 10 and Figure 11 As shown, the first guide track consists of two circumferentially distributed first slopes, with the higher point of one first slope adjacent to the lower point of the other. Similarly, the second guide track 211 also consists of two circumferentially distributed second slopes, with the higher point of one second slope adjacent to the lower point of the other. In the initial state, as... Figure 5 As shown, when the sharpening element 220 is in the retracted position after exiting the insert slot 110, the two first ramps and two second ramps are aligned and matched along the axial direction of the knob. The high points of the two first ramps are aligned with the low points of the two second ramps, and the low points of the two first ramps are aligned with the high points of the two second ramps, similar to two sets of saw teeth meshing together. At this time, the telescopic member 240 is closest to the knob. As the knob rotates in the first direction, it causes the two first ramps to climb along their respective corresponding second ramps. The high points of the two first ramps gradually approach the high points of the two second ramps. The high points of the two ramps approach and open the telescopic member 240, causing the telescopic member 240 to move away from the knob, thereby pushing the sharpening element 220 into the insert slot 110 (see reference). Figure 4 When the knob is rotated in the opposite direction, the higher points of the two first ramps gradually approach the lower points of the two second ramps, restoring the matching and engaging state. This facilitates the reset of the telescopic component 240 under the elastic force of the elastic component 230, and the reset of the sharpening element 220 under the elastic force of the elastic component 230 (see reference). Figure 5 ).

[0071] To ensure the knob is rotated to the correct position, it can be further rotated in a second direction opposite to the first direction until the high side of one of the first ramps abuts against the high side of the adjacent second ramp (non-axially connected second ramp) in the second direction. This helps to limit the rotation position of the knob, thereby ensuring that the grinding element 220 is completely removed from the tool slot 110.

[0072] Alternatively, limiting structures can be provided on the knob and at other locations to restrict the knob's rotational limit position in the first direction, thereby ensuring that the knob rotates to the correct position in the first direction, thus adjusting the extension of the sharpening element 220. Furthermore, the number of the first ramp and the number of the second ramp can be three or more, circumferentially distributed around the rotation center line of the knob.

[0073] In addition, such as Figure 4 and Figure 5 As shown, the elastic element 230 is a spring, and the sharpening element 220 has a spring mounting surface. The spring is fitted onto the spring mounting surface to ensure the sharpening element 220's return to its original position. The sharpening element 220 has a sharpening angle, such as a scissor-type opening 221, which is used for sharpening. Of course, the elastic element 230 may include, but is not limited to, the aforementioned spring, and may also be other structures.

[0074] Furthermore, such as Figure 3 , Figure 4 , Figures 7 to 10 As shown, the sharpening module 20 also includes: a sharpening base 260, which is disposed on the base body 10. The sharpening base 260 is provided with a clearance opening 261. The sharpening element 220 is disposed in the sharpening base 260 corresponding to the position of the clearance opening 261. An elastic member 230 is supported between the sharpening base 260 and the sharpening element 220. A telescopic member bracket 270 is disposed on the sharpening base 260. The telescopic member bracket 270 is provided with a through hole 272. The telescopic member 240 passes through the through hole 272 and abuts against the sharpening element 220 and can move along the through hole 272.

[0075] Here, the sharpening element 220, adjusting component 210, and transmission assembly are all directly or indirectly mounted on the sharpening holder 260, making the sharpening module 20 a single unit. Compared to the sharpening module 20's components being separately assembled on the holder body 10, this eliminates the need for a complex mounting structure and installation space on the holder body 10, simplifying manufacturing. Furthermore, a telescopic bracket 270 is provided within the sharpening holder 260, allowing the telescopic component 240 to move along the through hole 272, ensuring that the telescopic component 240 can accurately push the sharpening element 220.

[0076] Figure 4A schematic diagram shows the sharpening element 220 extending from the clearance opening 261. If the sharpening holder 260 is fixed to the tool holder body 10, the sharpening element 220 will also extend from... Figure 6 The grinding head 120 shown in the figure extends into the tool slot 110 and reaches the grinding position.

[0077] like Figure 4 , Figure 5 , Figure 7 and Figure 9 As shown, the telescopic bracket 270 includes a telescopic rod 242, and one end of the sharpening element 220 has a telescopic top plate 240 (here the spring top plate 222 can be used as the telescopic top plate 240). The telescopic rod 242 passes through the through hole 272 on the telescopic bracket 270 and contacts the telescopic top plate 240 of the sharpening element 220 to ensure force transmission.

[0078] To ensure that the telescopic component 240 moves along the set path, further, such as Figure 9 and Figure 10 As shown, the telescopic member 240 can have notches on both sides, and the telescopic member bracket 270 can be provided with two limiting posts 275. The two limiting posts 275 are respectively inserted into the two notches of the telescopic member 240. This can restrict the movement of the telescopic member 240 along the through hole 272 and also restrict the rotation of the telescopic member 240, thereby ensuring that the telescopic member 240 can convert the rotational motion of the knob into linear motion. Of course, the structure to prevent the rotation of the telescopic member 240 includes, but is not limited to, the two limiting posts 275 and the two notches mentioned above, and can also be other structures.

[0079] like Figure 7 As shown, the grinding base 260 is provided with a grinding base fixing hole 262, such as Figure 6 As shown, the tool holder body 10 is provided with mounting holes. Bolts pass through the grinding tool holder fixing hole 262 and are inserted into the mounting holes to achieve stable installation of the grinding tool holder 260 and the tool holder body 10. Figure 9 As shown, the telescopic bracket 270 is equipped with a fixing stud 273, such as... Figure 7 As shown, the grinding base 260 has a telescopic bracket fixing hole 263 corresponding to the fixing stud 273. A screw passes through the telescopic bracket fixing hole 263 and is inserted into the fixing stud 273, achieving stable installation of the telescopic bracket 270 and the grinding base 260. Figure 4 and Figure 5 As shown, the elastic member 230 is supported between the sharpening element 220 and the sharpening base 260. The elastic member 230 can apply a force to the sharpening element 220 that abuts against the telescopic member 240, which on the one hand facilitates the reset of the sharpening element 220 and the telescopic member 240, and on the other hand ensures that the telescopic member 240 can transmit the thrust to the sharpening element 220.

[0080] like Figure 8 As shown, one end of the sharpening element 220 has a scissor-type opening 221, which is used to sharpen the tool 30. The other end of the sharpening element 220 has a spring top plate 222. The elastic element 230 is a spring, which is sleeved on the sharpening element 220. One end of the spring abuts against the sharpening seat 260, and the other end abuts against the spring top plate 222. Of course, the elastic element 230 can also be other elastic structures, including but not limited to springs, and the specific structure of the sharpening element 220 can also be different. Figure 8 As shown, the design can be customized as needed.

[0081] Furthermore, such as Figure 4 and Figure 5 As shown, the transmission assembly also includes an elastic support 250, supported between the telescopic member bracket 270 and the telescopic member 240. The elastic support 250 is used to press the telescopic member 240 against the knob. The design of the elastic support 250 helps the telescopic member 240 to return to its original position. Combined with the thrust applied to the sharpening element 220 by the elastic member 230, the return effect is better. On the other hand, it ensures that the telescopic member 240 always remains in contact with the knob, thereby ensuring that rotating the knob can accurately drive the telescopic member 240 to move.

[0082] As an example, such as Figure 3 and Figure 4 As shown, the elastic support 250 is a spring, sleeved on the outer periphery of the telescopic member 240. One end of the spring abuts against the telescopic member bracket 270, and the other end abuts against the telescopic member 240. Of course, the elastic support 250 can also be a rubber part, etc.

[0083] Furthermore, such as Figure 9 and Figure 11 As shown, the telescopic bracket 270 is provided with a first stop 274, and the end face of the knob facing the telescopic member 240 is provided with a second stop 212. The knob can be rotated in a first direction until the first stop 274 abuts against the second stop 212. At this time, the sharpening element 220 can be in the sharpening position.

[0084] The design of the first stop 274 and the second stop 212 is beneficial for the user to know whether the knob has been rotated to the correct position when rotating it, and also ensures that the grinding element 220 is fully extended when the knob is fully rotated to the correct position.

[0085] As an example, such as Figure 9 and Figure 11As shown, the telescopic bracket 270 has an annular groove on its end face facing the knob. A stop rib is radially arranged within the annular groove, serving as a first stop rib 274. A positioning rib is provided on the end face of the knob facing the telescopic component 240, serving as a second stop rib 212. The positioning rib extends into the annular groove. During knob rotation in the first direction, the positioning rib can move within the annular groove until it abuts against the stop rib. This annular groove design helps restrict the movement path of the positioning rib, ensuring that the stop rib can effectively limit its movement. Furthermore, embedding the stop rib within the annular groove helps shorten the distance between the knobs on the telescopic bracket 270, reducing the space occupied by the grinding module 20. Additionally, to prevent the stop rib design from affecting the movement of the telescopic component 240, the annular groove can be located on the outer periphery of the telescopic component 240.

[0086] Of course, the above-mentioned annular groove can be omitted, and a protruding stop rib can be directly provided on the end face of the telescopic bracket 270 facing the knob. The stop rib serves as the first stop part 274, which has a simple structure and is easy to process.

[0087] Furthermore, such as Figure 4 , Figure 5 , Figure 11 and Figure 12 As shown, the telescopic bracket 270 has a telescopic protrusion 280 on the end face facing the knob, and the end face of the knob facing the telescopic component 240 has a circumferentially distributed wave-shaped guide rail 213. The telescopic protrusion 280 abuts against the wave-shaped guide rail 213. During the rotation of the knob, the telescopic protrusion 280 expands and contracts along the wave-shaped guide rail 213.

[0088] Specifically, when the knob is rotated, it drives the wave-shaped track to rotate, thereby repeatedly squeezing the retractable protrusion 280, causing it to continuously expand and contract. This increases the resistance to rotating the knob, and the retractable protrusion 280 also makes a clicking sound when it collides with the wave-shaped guide rail 213, which can enhance the user experience of rotating the knob.

[0089] It should be noted that the wavy track includes, but is not limited to, having a wavy surface, and can also have a sawtooth surface, as long as the circumferential concave and convex changes continuously, so that the retractable protrusions 280 can continuously expand and contract.

[0090] As an example, such as Figure 12 As shown, the retractable protrusion 280 may include a protrusion portion 281, a spring mounting post 282, and a spring 283. The protrusion portion 281 contacts the corrugated guide rail 213. The spring mounting post 282 is located at the end of the protrusion portion 281 away from the knob. The spring 283 is sleeved on the outer periphery of the spring mounting post 282 to press the protrusion portion 281 against the corrugated guide rail 213. This ensures that the retractable protrusion 280 is always in contact with the corrugated track, enabling retraction and expansion. Figure 4 , Figure 5 and Figure 9 As shown, the telescopic bracket 270 is provided with a protrusion mounting hole 271, and the telescopic protrusion 280 is set in the protrusion mounting hole 271. The protrusion mounting hole 271 not only provides installation space for the telescopic protrusion 280, but also has a limiting function to ensure that the telescopic protrusion 280 extends and retracts along a specified path.

[0091] As an example, the retractable protrusion 280 may also include a protrusion portion 281 and an elastic rubber member, which is disposed on the telescopic bracket 270 and presses the protrusion portion 281 against the corrugated guide rail 213.

[0092] There are various specific structures and placements of the retractable protrusions 280, not limited to the examples above.

[0093] Furthermore, such as Figure 4 , Figure 5 and Figure 11 As shown, the knob is provided with a buckle 214, and the telescopic component 240 support frame is provided with circumferentially distributed slots. The knob is fastened to the telescopic component 240 support frame by the buckle 214. During the rotation of the knob, the buckle 214 rotates in the slot, which can prevent the knob from falling off and does not affect the rotation of the knob.

[0094] The above describes the specific structure of the sharpening module 20 when the adjusting element 210 is a knob. Of course, the adjusting element 210 may not be a knob.

[0095] In other embodiments, the adjusting member 210 is a push button (not shown in the figure), and the sharpening module 20 also includes a ratchet mechanism (not shown in the figure) and a spring (not shown in the figure). The two ends of the ratchet mechanism are respectively connected to the push button and the sharpening element 220, and the spring is used to apply a force to the ratchet mechanism to move in the direction of the push button.

[0096] In these embodiments, the adjustment element 210 is a push button, which is easy to operate. Moreover, the push button is combined with a ratchet mechanism, so that when pressed once, the sharpening element 220 extends into the insert groove 110, and when pressed a second time, the sharpening element 220 retracts from the insert groove 110, which is beneficial for accurately controlling the sharpening element 220 to the designated position.

[0097] In other embodiments, the adjusting element 210 can also be a lever (not shown in the figure), with the lever and the sharpening element 220 being an integral structure. Moving the lever moves the sharpening element 220. The sharpening module 20 has few parts, a simple structure, is easy to manufacture, and is inexpensive. Moreover, the action of the sharpening element 220 can be controlled simply by reciprocating the lever, making operation convenient.

[0098] In this case, to prevent the sharpening element 220 from accidentally retracting, a limiting element can be configured to restrict the retraction of the lever, so that the sharpening element 220 can be kept in the sharpening position for sharpening.

[0099] Regarding the placement of the sharpening module 20, in some embodiments, such as... Figure 1 , Figure 2 and Figure 3 As shown, the outer surface of the tool holder body 10 is provided with a recess, and the sharpening module 20 is embedded in the recess. The tool holder has good overall integrity and a good appearance.

[0100] As an example, such as Figure 1 , Figure 2 and Figure 3 As shown, the tool holder body 10 is inclined, and a recess is provided on the front side, i.e. the front end surface, of the tool holder body 10, so that the sharpening element 220 can approach the blade and sharpen it.

[0101] Furthermore, in some embodiments, the sharpening module 20 is detachably connected to the tool holder body 10. This facilitates the replacement of the sharpening module 20, thereby utilizing new sharpening elements 220 to sharpen the tool 30 and ensuring effective sharpening.

[0102] The tool holder provided in this embodiment of the utility model has a built-in sharpening module 20, which can automatically sharpen the blade during the process of the tool 30 entering and exiting the tool slot 110. At the same time, the sharpening state can be adjusted. When sharpening is not required, the sharpening element 220 can be hidden. When sharpening is required, the sharpening element 220 can be brought out. For example, the two states of automatic sharpening and non-automatic sharpening can be switched by rotating the knob, which can avoid damage to the originally sharp tool 30 or the new tool 30 due to sharpening.

[0103] While the embodiments of the present invention have been described in detail above, those skilled in the art can make various modifications and variations to the embodiments of the present invention without departing from the spirit and scope thereof. It should be understood that, to those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
