[0002] Knives are essential tools in people's daily lives. To store knives, they are usually used in conjunction with a knife holder. And since the knife edges will become worn and dull after long-term use, the knife holder is equipped with a sharpening assembly that can sharpen the knife edges. However, due to the different blade angles of different knife types, when the sharpening angle of the sharpening assembly is significantly different from the blade angle, it is easy to cause damage to the knife or inability to sharpen the knife during the sharpening process. Summary of the Utility Model

[0003] In view of this, this application provides a sharpening assembly and a knife holder to facilitate solving the technical problem that the sharpening angle of the sharpening assembly in the prior art cannot be adjusted.

[0004] In a first aspect, an embodiment of this application provides a sharpening assembly. The sharpening assembly includes: a housing having an accommodation cavity, and the housing is provided with a first groove that communicates with the accommodation cavity; a sharpening member movably connected to the housing, and the sharpening member can extend from the accommodation cavity to the first groove, and the sharpening member is used to contact the knife when the knife passes through the first groove; wherein, the sharpening assembly further includes an arc-shaped elastic member, one end of the elastic member is connected to the housing, and the other end of the elastic member abuts against the sharpening member.

[0005] In this embodiment, since different types of knives usually have different blade angles, the sharpening member is movably connected to the housing, so that when the sharpening member contacts the blades at different angles, it can move under the action of the blades to adapt to different blade angles, improve the sharpening effect on the knives, and can improve the applicability of the sharpening assembly. And the sharpening member is connected to the elastic member, and under the action of the resilience of the elastic member, the sharpening member can always fit with the blade, further improving the sharpening effect. At the same time, when the sharpening work is completed, the sharpening member can automatically return to the initial position under the action of the elastic member, which is convenient for the next use.

[0006] In a specific embodiment, the housing further includes an arc-shaped installation groove, and the elastic member is installed in the installation groove.

[0007] In this embodiment, the housing includes an arc-shaped mounting groove, and the shape and radian of the mounting groove are the same as those of the elastic member, so that it can be used to fix the elastic member, and the elastic deformation direction of the elastic member is along the extension direction of the mounting groove, improving the reliability of the elastic deformation of the elastic member, and helping the trajectory of the elastic deformation of the elastic member to be the same as the trajectory when the sharpening member rotates, enhancing the stability and reliability of the sharpening member during the rotation under the action of the elastic restoring force of the elastic member.

[0008] In a specific embodiment, the housing is further provided with a rotating shaft, one end of the sharpening member is rotatably connected to the housing through the rotating shaft, and the other end of the sharpening member extends into the mounting groove and elastically abuts against the elastic member.

[0009] In this embodiment, one end of the sharpening member is connected to the housing through a rotating shaft, so that the sharpening member can rotate relative to the housing around the rotating shaft, and the other end of the sharpening member extends into the mounting groove, which can improve the stability of the sharpening member during rotation and further enhance the connection reliability between the sharpening member and the elastic member.

[0010] In a specific embodiment, the center of the mounting groove coincides with the center of the rotating shaft.

[0011] In this embodiment, the center of the mounting groove coincides with the center of the rotating shaft, so that the shape of the mounting groove is the same as the arc shape formed by the movement trajectory of the sharpening member when it rotates around the rotating shaft. Thus, the elastic deformation direction of the elastic member is the same as the arc shape formed by the movement trajectory of the sharpening member when it rotates around the rotating shaft, and the direction of the elastic force exerted by the elastic member on the sharpening member is the same as the rotation direction of the sharpening member, preventing the elastic force of the elastic member from forming a torque and ensuring that the sharpening member can rotate normally in the mounting groove.

[0012] In a specific embodiment, the housing is further provided with a first limiting portion and a second limiting portion that are spaced apart along the rotation direction of the sharpening member. The first limiting portion and the second limiting portion are respectively used to abut against the sharpening member along the rotation direction to limit the extreme rotation angle of the sharpening member.

[0013] In this embodiment, by providing the first limiting portion and the second limiting portion on the housing, they can be respectively used to abut against the sharpening member along the rotation direction to limit the rotation range of the sharpening member, thereby limiting the extreme range of the sharpening angle formed by the sharpening member and reducing the risk of the sharpening member disengaging from the mounting groove during rotation.

[0014] In a specific embodiment, the side wall of the mounting groove includes a first arc-shaped wall and a second arc-shaped wall. The central angle of the first arc-shaped wall is greater than the central angle of the second arc-shaped wall; the first limiting portion includes a protrusion connected to the first arc-shaped wall, and the second limiting portion includes the end portion of the second arc-shaped wall along the rotation direction of the sharpening member.

[0015] In this embodiment, the central angle of the first arc-shaped wall is made larger than that of the second arc-shaped wall, that is, the arc length of the first arc-shaped wall is made larger than that of the second arc-shaped wall, so as to provide a rotation space for the part of the sharpening member in the installation groove to rotate around the rotation axis, so as to adjust the angle of the sharpening member. In addition, the first limiting portion may include a protrusion connected to the first arc-shaped wall. When the sharpening member rotates to abut against the first limiting portion under the action of the resilience of the elastic member, the first limiting portion can limit the continuous rotation of the sharpening member, so that the sharpening member has a minimum sharpening angle, which can be adapted to a tool with a smaller blade thickness, and the first limiting portion can also prevent the part of the structure of the sharpening member located in the installation groove from detaching from the installation groove, affecting normal use; when the sharpening member rotates to abut against the second limiting portion under the action of the tool, the second limiting portion can limit the continuous rotation of the sharpening member, so that the sharpening member has a maximum sharpening angle, which can be adapted to a tool with a larger blade thickness.

[0016] In a specific embodiment, the housing further includes a mounting portion, the mounting portion protrudes in a direction away from the first arc-shaped wall relative to the second arc-shaped wall, and the mounting portion is flush with the end of the second arc-shaped wall along the rotation direction of the sharpening member, and the second limiting portion further includes the mounting portion.

[0017] In this embodiment, the housing is provided with a mounting portion, and mounting holes corresponding to the grooves can be provided on the mounting portion, further improving the connection reliability between the housing and the base. And the second limiting portion includes not only the end of the first arc-shaped wall but also the mounting portion. When the sharpening member abuts against the second limiting portion, the contact area between the two can be increased, and the blocking effect of the second limiting portion on the sharpening member can be improved.

[0018] In a specific embodiment, the sharpening member includes a first sharpening member and a second sharpening member, and the elastic member includes a first elastic member connected to the first sharpening member and a second elastic member connected to the second sharpening member; the first sharpening member and the second sharpening member are rotatably connected to the housing through the same rotation axis, and the first elastic member and the second elastic member are symmetrically arranged on both sides of the rotation axis.

[0019] In this embodiment, the sharpening member includes a first sharpening member and a second sharpening member arranged oppositely, so that when the sharpening assembly is in use, the two sides of the blade of the tool can be sharpened simultaneously, improving the sharpening efficiency. And the first elastic member and the second elastic member are symmetrically arranged on both sides of the rotation axis. When the tool contacts the first sharpening member and the second sharpening member, the central angles of the first sharpening member and the second sharpening member rotating around the rotation axis can be the same, so that the sharpening effects of the first sharpening member and the second sharpening member on the blade are the same, avoiding the phenomenon of excessive sharpening on one side of the blade. And in this embodiment, the installation groove may include a first installation groove and a second installation groove, which are respectively used for installing the first elastic member and the second elastic member.

[0020] In a specific embodiment, the first sharpening member includes a first contact portion and a first connecting portion, the second sharpening member includes a second contact portion and a second connecting portion, the first connecting portion is rotatably connected to the housing through the rotating shaft, and the second connecting portion is rotatably connected to the housing through the rotating shaft; the first contact portion is connected to the first elastic member, and the second contact portion is connected to the second elastic member; the first contact portion has a T-shaped structure, and the second contact portion has an L-shaped structure.

[0021] In this embodiment, the sharpening member has a contact portion with a relatively large cross-sectional area, so as to improve the reliability and stability when the sharpening member is connected to the elastic member. At the same time, when the sharpening assembly includes a first sharpening member and a second sharpening member, during the process of sharpening the knife, the first sharpening member and the second sharpening member need to be stacked, with the first sharpening member located below the second sharpening member. Making the first contact portion have a T-shaped structure can increase the contact area between the first contact portion and the first elastic member, thereby improving the connection reliability and stability; the second sharpening member is located above the first sharpening member, and the second elastic member is located below the second contact portion. Making the second contact portion have an L-shaped structure can increase the contact area between the second contact portion and the second elastic member, thereby improving the connection reliability and stability.

[0022] In a specific embodiment, the elastic member is in a compressed state.

[0023] In this embodiment, when the elastic member is installed in the accommodating cavity, the elastic member can be in an elastically deformed state (i.e., a compressed state) so that the elastic member always has a resilience force. Thus, during the rotation of the sharpening member, the sharpening member can always be subjected to the resilience force, and further, the sharpening member can always be kept in close contact with the blade portion of the tool, further improving the sharpening effect of the sharpening member on the tool.

[0024] In a specific embodiment, the housing includes a detachable body and a cover, and the body and the cover enclose the accommodating cavity.

[0025] In this embodiment, the components of the sharpening assembly such as the sharpening member and the elastic member are installed on the body. Making the housing include a detachable body and a cover is convenient for the installation of the components on the body and subsequent maintenance and replacement. Moreover, the cover can provide protection for the components on the body, avoiding direct contact with the outside world and extending its service life.

[0026] In a second aspect, an embodiment of the present application provides a knife holder, the knife holder includes: a base and a sharpening assembly, the base has a second groove penetrating the base in the thickness direction of the knife holder; wherein, the sharpening assembly is installed on the base, and in the thickness direction of the knife holder, the first groove communicates with the second groove.

[0027] In this embodiment, a tool storage groove can be provided on the tool rest, and the sharpening assembly is installed on the base, so that the tool rest has the functions of placing and sharpening the tool at the same time, improving the functionality of the tool rest, and avoiding the loss of the sharpening assembly. Moreover, the second groove on the base is communicated with the first groove of the sharpening assembly. When sharpening the tool, the cutting edge part of the tool can be integrally placed in the first groove and the second groove and reciprocated to improve the sharpening effect of the tool and avoid the user directly contacting the cutting edge part of the tool, thus improving the use safety.

[0028] In a specific embodiment, the base has a third groove, and the sharpening assembly can be placed in the third groove and is detachably connected to the base.

[0029] In this embodiment, the base can have a third groove, and the sharpening assembly can be placed in the third groove and is detachably connected to the base. While improving the connection reliability between the sharpening assembly and the base, it is convenient for the disassembly, replacement or repair of the sharpening assembly.

[0075] For a better understanding of the technical solutions of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0076] It should be clear that the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0077] The terms used in the embodiments of this application are only for the purpose of describing specific embodiments, and are not intended to limit this application. The singular forms of "a", "the" and "said" used in the embodiments of this application and the appended claims are also intended to include the plural forms, unless the context clearly indicates otherwise.

[0078] It should be understood that the term " / and / " used herein is only a description of the associated relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0079] As Figure 1 shown, the embodiments of this application provide a sharpening assembly 11 and a tool rest 1 including the sharpening assembly 11. At the same time, asFigure 2 and Figure 3 As shown in Figure 3 , the sharpening assembly 11 includes a housing 111 and a sharpening member 113. The housing 111 has a receiving cavity, and the housing 111 is provided with a first groove 112. The first groove 112 communicates with the receiving cavity. The sharpening member 113 is movably connected to the housing 111, and at least a part of the structure of the sharpening member 113 can extend into the first groove 112. Thus, when the tool 2 passes through the first groove 112, the sharpening member 113 can contact the tool 2 to sharpen the tool 2.

[0080] In a possible embodiment of the present application, the sharpening assembly 11 can be used alone or installed on the tool holder 1.

[0081] In a specific embodiment, as Figures 1 to 5 shown, the tool holder 1 may include a base 12. The base 12 has a second groove 121 penetrating through the base 12 in the thickness direction of the tool holder 1. When the sharpening assembly 11 is installed on the base 12, the first groove 112 communicates with the second groove 121 in the thickness direction of the tool holder 1.

[0082] In this embodiment, a tool storage groove 122 can be provided on the tool holder 1, and the sharpening assembly 11 is installed on the base 12, so that the tool holder 1 can simultaneously place and sharpen the tool 2, improving the functionality of the tool holder 1 and preventing the loss of the sharpening assembly 11. And in the thickness direction of the tool holder 1, the second groove 121 on the base 12 communicates with the first groove 112 of the sharpening assembly 11. When sharpening the tool 2, the cutting edge part of the tool 2 can be entirely placed in the first groove 112 and the second groove 121 and reciprocated to improve the sharpening effect of the tool 2 and prevent the user from directly contacting the cutting edge part of the tool 2, improving the use safety.

[0083] In the above embodiments, the base 12 may have a third groove 123. The sharpening assembly 11 can be placed in the third groove 123 and detachably connected to the base 12, improving the connection reliability between the sharpening assembly 11 and the base 12 and facilitating the disassembly, replacement or repair of the sharpening assembly 11. Among them, the connection method between the sharpening assembly 11 and the third groove 123 includes but is not limited to screwing or clamping.

[0084] In an embodiment of the present application, the sharpening assembly 11 may further include an arc-shaped elastic member 114. One end of the elastic member 114 is connected to the housing 111, and the other end of the elastic member 114 abuts against the sharpening member 113.

[0085] In this embodiment, since different types of cutting tools usually have different blade angles, the sharpening member 113 is movably connected to the housing 111, so that when the sharpening member 113 comes into contact with blades at different angles, it can move under the action of the blades to adapt to different blade angles, improve the sharpening effect on the cutting tool 2, and enhance the applicability of the sharpening assembly 11. And the sharpening member 113 is connected to the elastic member 114, and under the action of the resilience of the elastic member 114, the sharpening member 113 can always be in contact with the blade, further improving the sharpening effect. At the same time, when the sharpening work is completed, the sharpening member 113 can automatically return to the initial position under the action of the elastic member 114, which is convenient for the next use.

[0086] In a specific embodiment, the sharpening member 113 can rotate relative to the housing 111 to adapt to different blade angles, and the elastic member 114 is arc-shaped, so that the movement trajectory of the elastic member 114 during elastic deformation is close to or the same as the rotation trajectory of the sharpening member 113, so that the direction of the external force exerted by the elastic member 114 on the sharpening member 113 is the same as or has a small included angle with the rotation direction of the sharpening member 113, improving the stability of the rotation of the sharpening member 113.

[0087] In another specific embodiment, the sharpening member 113 can move relative to the housing 111. Since different types of cutting tools usually have different blade thicknesses, the sharpening member 113 can move relative to the housing 111. During the process of placing the cutting tool 2 into the first groove 112, the sharpening member 113 can move under the action of the cutting tool 2, providing a placement space for cutting tools 2 with different thicknesses, and avoiding damage to the blade surface part of the cutting tool 2 during the placement process.

[0088] When the elastic member 114 is installed in the accommodating cavity, the elastic member 114 can be in an elastically deformed state (i.e., a compressed state), so that the elastic member 114 always has resilience, so that during the rotation of the sharpening member 113, the sharpening member 113 can always be under the action of the resilience, and further make the sharpening member 113 always keep in close contact with the blade part of the cutting tool 2, further improving the sharpening effect of the sharpening member 113 on the cutting tool 2.

[0089] Among them, in this embodiment, the elastic member 114 can be an arc-shaped spring with an arc-shaped self, to improve the working stability of the elastic member 114, or the elastic member 114 can also be a silicone pad processed into an arc shape.

[0090] In a specific embodiment, as Figure 6 and Figure 7 shown, the housing 111 can also include an arc-shaped installation groove 115, and the elastic member 114 is installed in the installation groove 115.

[0091] In this embodiment, the housing 111 is made to include an arc-shaped mounting groove 115, and the shape and radian of the mounting groove 115 are both the same as those of the elastic member 114, so that it can be used to fix the elastic member 114, and the elastic deformation direction of the elastic member 114 is along the extending direction of the mounting groove 115, improving the reliability of the elastic deformation of the elastic member 114, and helping to make the trajectory of the elastic deformation of the elastic member 114 the same as the trajectory when the sharpening member 113 rotates, enhancing the stability and reliability of the sharpening member 113 during the rotation under the action of the resilience of the elastic member 114.

[0092] In a specific embodiment, as Figure 6 and Figure 7 shown, the housing 111 may further have a rotating shaft 118. One end of the sharpening member 113 is rotatably connected to the housing 111 through the rotating shaft 118. The other end of the sharpening member 113 extends into the mounting groove 115 and elastically abuts against the elastic member 114.

[0093] In this embodiment, one end of the sharpening member 113 is connected to the housing 111 through the rotating shaft 118, so that the sharpening member 113 can rotate relative to the housing 111 around the rotating shaft 118, and the other end of the sharpening member 113 extends into the mounting groove 115, which can improve the stability of the sharpening member 113 during rotation and further enhance the connection reliability between the sharpening member 113 and the elastic member 114.

[0094] In a specific embodiment, as Figure 6 and Figure 7 shown, the center of the mounting groove 115 coincides with the center of the rotating shaft 118.

[0095] In this embodiment, the center of the mounting groove 115 is made to coincide with the center of the rotating shaft 118, so that the shape of the mounting groove 115 is the same as the arc shape formed by the movement trajectory when the sharpening member 113 rotates around the rotating shaft 118. Thus, the elastic deformation direction of the elastic member 114 is the same as the arc shape formed by the movement trajectory when the sharpening member 113 rotates around the rotating shaft 118, and the elastic force direction applied by the elastic member 114 to the sharpening member 113 is the same as the rotation direction of the sharpening member 113, preventing the elastic force of the elastic member 114 from forming a torque and ensuring that the sharpening member 113 can rotate normally in the mounting groove 115.

[0096] In another specific embodiment, the structure that restricts the elastic member to be arc-shaped can also be a plurality of positioning posts (not shown in the figure) provided on the housing. The plurality of positioning posts are arranged at intervals along the arc, and the elastic member is arranged between the plurality of positioning posts, so that it can be used to fix the elastic member, making the trajectory of the elastic deformation of the elastic member the same as the trajectory when the sharpening member rotates, enhancing the stability and reliability of the elastic member during elastic deformation, and avoiding the existence of torsional force in the elastic member during elastic deformation.

[0097] In a specific embodiment, as Figure 6 and Figure 7 shown, the housing 111 may further be provided with a first limiting portion 115e and a second limiting portion 115f that are spaced apart along the rotation direction of the sharpening member 113. The first limiting portion 115e and the second limiting portion 115f are respectively used to abut against the sharpening member 113 along the rotation direction to limit the extreme rotation angle of the sharpening member 113.

[0098] In this embodiment, by providing the first limiting portion 115e and the second limiting portion 115f on the housing 111, they can be respectively used to abut against the sharpening member 113 along the rotation direction to define the rotation range of the sharpening member 113, thereby defining the extreme range of the sharpening angle formed by the sharpening member 113 and reducing the risk of the sharpening member 113 disengaging from the mounting groove 115 during rotation.

[0099] The specific structures of the first limiting portion 115e and the second limiting portion 115f are described in detail below.

[0100] In a specific embodiment, as Figures 6 to 8 shown, the side wall of the mounting groove 115 may include a first arc wall 115c and a second arc wall 115d. The first arc wall 115c and the second arc wall 115d are distributed radially along the rotation trajectory of the sharpening member 113, and the distance between the first arc wall 115c and the center of the rotating shaft 118 is greater than the distance between the second arc wall 115d and the center of the rotating shaft 118. The central angle of the first arc wall 115c is greater than the central angle of the second arc wall 115d; the first limiting portion 115e may include a protrusion connected to the first arc wall 115c, and the second limiting portion 115f may include an end portion of the second arc wall 115d along the rotation direction of the sharpening member 113.

[0101] In this embodiment, making the central angle of the first arc wall 115c greater than the central angle of the second arc wall 115d, that is, making the arc length of the first arc wall 115c greater than the arc length of the second arc wall 115d, can provide a rotation space for the part of the structure of the sharpening member 113 in the mounting groove 115 to rotate around the rotating shaft 118 to adjust the angle of the sharpening member 113. In addition, as Figure 6 and Figure 7 shown, the first limiting portion 115e may include a protrusion connected to the first arc wall 115c. When the sharpening member 113 rotates to abut against the first limiting portion 115e under the action of the resilience of the elastic member 114, the first limiting portion 115e can limit the further rotation of the sharpening member 113, so that the sharpening member 113 has a minimum sharpening angle, can be adapted to a tool with a smaller cutting edge thickness, and the first limiting portion 115e can also prevent the part of the structure of the sharpening member 113 located in the mounting groove 115 from disengaging from the mounting groove 115 and affecting normal use; as Figure 6 and Figure 8As shown, when the sharpening member rotates under the action of the tool and abuts against the second limiting portion 115f, the second limiting portion 115f can limit the continuous rotation of the sharpening member, so that the sharpening member has the maximum sharpening angle and can be adapted to a tool with a larger cutting edge thickness.

[0102] In this embodiment, the end of the second arc-shaped wall 115d can be the second limiting portion 115f.

[0103] In a specific embodiment, as Figure 6 shown, the housing 111 may further include a mounting portion 111a. The mounting portion 111a protrudes in a direction away from the first arc-shaped wall 115c with respect to the second arc-shaped wall 115d, and the mounting portion 111a is flush with the end of the second arc-shaped wall 115d along the rotation direction of the sharpening member. In this embodiment, the second limiting portion 115f may include the end of the second arc-shaped wall 115d and the mounting portion 111a.

[0104] In this embodiment, the housing 111 is provided with a mounting portion 111a. Mounting holes corresponding to the grooves may be provided on the mounting portion 111a, further improving the connection reliability between the housing 111 and the base. And the second limiting portion 115f includes not only the end of the first arc-shaped wall 115c but also the mounting portion 111a. When the sharpening member abuts against the second limiting portion 115f, the contact area between the two can be increased, and the blocking effect of the second limiting portion 115f on the sharpening member can be improved.

[0105] In a specific embodiment, as Figures 6 to 8 shown, the sharpening member 113 may further include a first sharpening member 113a and a second sharpening member 113b. The elastic member 114 may further include a first elastic member connected to the first sharpening member 113a and a second elastic member 114b connected to the second sharpening member 113b. The first sharpening member 113a and the second sharpening member 113b are rotatably connected to the housing 111 through the same rotating shaft 118, and the first elastic member 114a and the second elastic member 114b are symmetrically arranged on both sides of the rotating shaft 118.

[0106] In this embodiment, the sharpening member 113 includes a first sharpening member 113a and a second sharpening member 113b which are oppositely arranged. When the sharpening assembly is in use, the two side edges of the tool can be sharpened simultaneously, improving the sharpening efficiency. Moreover, the first elastic member 114a and the second elastic member 114b are symmetrically arranged on both sides of the rotating shaft 118. When the tool contacts the first sharpening member 113a and the second sharpening member 113b, the central angles by which the first sharpening member 113a and the second sharpening member 113b rotate around the rotating shaft 118 are the same, so that the sharpening effects of the first sharpening member 113a and the second sharpening member 113b on the edge are the same, avoiding the phenomenon of excessive sharpening on one side of the edge. And in this embodiment, the installation groove 115 can include a first installation groove 115a and a second installation groove 115b, which are respectively used for installing the first elastic member 114a and the second elastic member 114b.

[0107] In a specific embodiment, as Figure 3 、 Figures 8 to 10 shown, the first sharpening member 113a can include a first contact portion 116a and a first connecting portion 117a, and the second sharpening member 113b can include a second contact portion 116b and a second connecting portion 117b. The first connecting portion 117a is rotatably connected to the housing 111 through the rotating shaft 118, and the second connecting portion 117b is rotatably connected to the housing 111 through the rotating shaft 118; the first contact portion 116a is connected to the first elastic member 114a, and the second contact portion 116b is connected to the second elastic member 114b; the first contact portion 116a can be in a T-shaped structure, and the second contact portion 116b can be in an L-shaped structure.

[0108] In this embodiment, the sharpening member 113 has a contact portion 116 with a relatively large cross-sectional area, which can improve the reliability and stability when the sharpening member 113 is connected to the elastic member 114. At the same time, when the sharpening assembly 11 includes the first sharpening member 113a and the second sharpening member 113b, during the process of sharpening the knife, the first sharpening member 113a and the second sharpening member 113b need to be stacked. The first sharpening member 113a is located below the second sharpening member 113b. Making the first contact portion 116a in a T-shaped structure can increase the contact area between the first contact portion 116a and the first elastic member 114a, thus improving the connection reliability and stability; the second sharpening member 113b is located above the first sharpening member 113a, and the second elastic member 114b is located below the second contact portion 116b. Making the second contact portion 116b in an L-shaped structure can increase the contact area between the second contact portion 116b and the second elastic member 114b, thus improving the connection reliability and stability.

[0109] In a specific embodiment, as Figure 3 and Figure 4As shown, the housing 111 may further include a main body 120 and a cover 119 that are detachably connected, and the main body 120 and the cover 119 enclose a receiving cavity.

[0110] In this embodiment, the components of the sharpening assembly 11 such as the sharpening member 113 and the elastic member 114 are installed on the main body 120, so that the housing 111 includes the main body 120 and the cover 119 that are detachably connected, which facilitates the installation of the components on the main body 120 and subsequent maintenance and replacement. Moreover, the cover 119 can provide protection for the components on the main body 120 to avoid direct contact with the outside world and extend their service life. Among them, the connection manner between the main body 120 and the cover 119 includes but is not limited to screwing and clamping.

[0111] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
