Description

Technical Field

[0001] This application relates to the field of stationery technology, and more specifically to a pencil sharpener. Background Technology

[0002] A pencil sharpener is a tool used to cut and sharpen pencils. It works by using a blade to move relative to the inserted pencil, removing the outer wood layer to expose the lead and create a sharp tip for writing or drawing. Pencil sharpeners are widely used in learning, office work, and art. The advent of pencil sharpeners has greatly improved the efficiency of sharpening pencils and reduced the inconvenience and danger of manual sharpening. Traditional pencil sharpeners are mainly designed for common writing pencils and only meet general writing needs. These sharpeners typically only adjust the tip thickness, not the sharpening angle. For special-purpose pens, such as sketching pens and drawing pens, the lead hardness, diameter, and tip shape requirements differ from ordinary writing pencils. For example, writing pencils require a sharper tip, while drawing pencils require a flatter tip to better represent shading. Traditional pencil sharpeners cannot meet the diverse needs of users for different tip shapes in different scenarios. Users need to manually adjust the sharpening method according to different pen types or prepare multiple pencil sharpeners with different functions, which greatly increases usage costs and time, and reduces work efficiency. Therefore, there is an urgent need for a pencil sharpener that can simultaneously meet the requirements of multiple specifications of sharpening. Summary of the Invention

[0003] The technical problem to be solved by this application is to provide a pencil sharpener that adjusts the position of the pencil sharpening mechanism within the housing by setting an angle adjustment mechanism, thereby changing the communication angle between the pencil sharpening mechanism and the first pen inlet, realizing the adjustable pencil sharpening angle function, which can simultaneously meet the needs of various specifications of pen products for sharpening, improving work efficiency and reducing usage costs.

[0004] This application provides a pencil sharpener, including a housing and a pencil sharpening mechanism. The housing is provided with a first pencil inlet communicating with the pencil sharpening mechanism. The pencil sharpening mechanism is movably installed inside the housing. The housing is also equipped with an angle adjustment mechanism, which is connected to the pencil sharpening mechanism. The angle adjustment mechanism is used to drive the pencil sharpening mechanism to move within the housing. The pencil sharpening mechanism adjusts the communication angle with the first pencil inlet by moving within the housing.

[0005] In this technical solution, the first inlet is mainly used to insert the pen to be sharpened. The pen passes through the first inlet and is inserted into the sharpening mechanism for sharpening. A movable sharpening mechanism is provided, which moves to change its connection angle with the first inlet, thereby changing the sharpening angle of the pen to meet the sharpening needs of different pen types. By adding an angle adjustment mechanism to the housing, which is connected to the sharpening mechanism, the sharpening mechanism can be adjusted within the housing, thereby changing its relative angle with the first inlet. This allows the sharpener to adjust the sharpening angle according to different pen types (such as writing pencils, sketching pens, drawing pens, etc.). Users do not need to change to different types of sharpeners or manually adjust the sharpening method; they only need to apply force to the angle adjustment mechanism to adjust the sharpening angle, greatly improving the convenience of use. This sharpener can simultaneously sharpen multiple sizes of pen products, improving work efficiency and reducing operating costs.

[0006] As an improvement, the angle adjustment mechanism includes a push button and an adjusting member. The push button is slidably mounted on the housing, and the adjusting member is connected to the pencil sharpening mechanism. When the push button is slid under force, it drives the adjusting member to slide synchronously. The adjusting member drives the pencil sharpening mechanism to swing within the housing by sliding, thereby adjusting the communication angle between the pencil sharpening mechanism and the first pen inlet. In this technical solution, the push button serves as the direct component operated by the user. The push button is slidably mounted on the housing and connected to the adjusting member. The user can apply force to the push button to drive the adjusting member to slide synchronously. The adjusting member is connected to the pencil sharpening mechanism and acts as a force transmitter, ensuring that the sliding of the push button can be converted into the swinging of the pencil sharpening mechanism, thereby achieving the adjustment of the pencil sharpening angle. The user only needs to push the push button to adjust the pencil sharpening angle. The operation is intuitive and simple. The sliding design of the push button makes the angle adjustment process fast and continuous, improving work efficiency.

[0007] More preferably, the housing is provided with a first sliding groove for slidingly mounting the push button. The push button is provided with a connecting rod, which passes through the first sliding groove and connects to the adjusting component. The first sliding groove provides a fixed sliding path for the push button, ensuring that the push button remains stable during sliding and avoiding deviation or jamming caused by external forces. The push button is connected to the adjusting component through the connecting rod, which is used to transmit the sliding action of the push button, so that the push button and the adjusting component can slide synchronously to realize the adjustment of the pencil sharpening angle. The connection method is simple and the sliding is smoother and more reliable. More preferably, the housing is provided with a second sliding groove for slidingly mounting the adjusting component. The second sliding groove provides a fixed sliding path for the adjusting component, ensuring that the adjusting component remains stable during sliding and avoiding deviation or jamming caused by external forces.

[0008] As an improvement, the pencil sharpening mechanism is equipped with a linkage protrusion, and the adjusting member is connected to the linkage protrusion. The adjusting member slides on the linkage protrusion to cause the pencil sharpening mechanism to swing. In this technical solution, the pencil sharpening mechanism is mechanically linked with the adjusting member by setting the linkage protrusion. The sliding action of the adjusting member is applied to the pencil sharpening mechanism through the linkage protrusion, causing the pencil sharpening mechanism to swing within the housing. This makes the drive more reliable and efficient. The connection between the adjusting member and the linkage protrusion can be direct contact or indirect connection through other intermediate components, ensuring that the sliding of the adjusting member can be effectively transmitted to the pencil sharpening mechanism. The design of the linkage protrusion makes the swing of the pencil sharpening mechanism more stable and precise.

[0009] As an improvement, the adjusting component is equipped with multiple adjustment positions. These positions are connected to a linkage protrusion to position the sharpening mechanism. The adjusting component can be slid to switch between different adjustment positions connected to the linkage protrusion. In this technical solution, the adjustment positions are positioning points used to control the swing of the sharpening mechanism. Each position corresponds to a specific sharpening angle, ensuring consistency of the pen tip during each sharpening. The connection between the adjustment positions and the linkage protrusions drives and positions the sharpening mechanism. Users can switch between different adjustment positions by sliding the adjusting component; the operation is simple and intuitive. Users can quickly select the appropriate sharpening angle as needed. When the adjusting component slides, different adjustment positions are sequentially connected to the linkage protrusion, thereby driving the sharpening mechanism to swing to different positions within the housing, achieving adjustment of the sharpening angle. Furthermore, when the adjusting component is not subjected to the force of the push button, the adjustment position can abut against the linkage protrusion, thus positioning the sharpening mechanism. This ensures stable positioning of the sharpening mechanism at each position, reducing problems such as pen lead breakage or uneven sharpening caused by unstable angles during sharpening.

[0010] As an improvement, multiple adjustment positions are connected sequentially along an oblique direction, forming a stepped structure, and the linkage protrusion has a cylindrical structure. In this technical solution, multiple adjustment positions are connected sequentially along an oblique direction to form a stepped structure, allowing the linkage protrusion to switch between positions at different oblique angles. Each adjustment position has a different contact with the linkage protrusion, creating a distinct sense of hierarchy, thereby achieving adjustment of the sharpening angle. Each adjustment position corresponds to a fixed sharpening angle, ensuring that the sharpening mechanism can accurately stop at a predetermined position during swinging, thus achieving precise angle adjustment. The stepped structure allows for more stable positioning of the sharpening mechanism when switching positions. Furthermore, the cylindrical structure of the linkage protrusion provides good contact stability and movement flexibility when connected to the adjustment position. The cylindrical linkage protrusion forms a tangential relationship with the contact surface of the adjustment position, ensuring smooth switching between different positions during the sliding process of the adjustment component, improving efficiency.

[0011] As an improvement, the adjusting member is provided with an elastic positioning structure, and the housing is provided with multiple positioning grooves. The elastic positioning structure abuts against the positioning grooves to allow the adjusting member to slide and be positioned. The adjusting member slides under force to allow the elastic positioning structure to switch between different positioning grooves. In this technical solution, an elastic positioning structure is provided on the adjusting component. This elastic positioning structure has elastic force and can abut against the positioning grooves within the housing. By abutting against different positioning grooves, the elastic positioning structure achieves stable positioning of the adjusting component at different positions. When the adjusting component slides under the force of the push button, the elastic positioning structure disengages from one positioning groove and enters the next under the action of elastic force, thereby adjusting the position of the pencil sharpening mechanism. Multiple positioning grooves are provided within the housing, distributed along the sliding direction of the adjusting component. Each positioning groove corresponds to a specific pencil sharpening angle. The positioning grooves provide positioning points for the elastic positioning structure, ensuring that the adjusting component can stably remain at each position. By switching between different positioning grooves, the user can precisely select the pencil sharpening angle. The user applies force to slide the push button, causing the elastic positioning structure to switch between different positioning grooves. Each positioning groove corresponds to a fixed pencil sharpening angle, ensuring consistency of the pencil tip each time and improving the pencil sharpening quality. It should be noted that the elastic positioning structure can specifically be an elastic arm structure with a positioning block, or it can be located on the push button; the principle is the same and will not be elaborated further.

[0012] As an improvement, the pencil sharpening mechanism is equipped with a positioning post, and the inner wall of the housing is provided with a mounting groove adapted to the positioning post. The positioning post and the mounting groove are rotatably connected, allowing the pencil sharpening mechanism to swing back and forth within the housing. In this technical solution, the positioning post and the mounting groove are rotatably connected, allowing the pencil sharpening mechanism to swing back and forth within the housing. This enables the pencil sharpening mechanism to adjust its angle within the housing through swinging. The positioning post acts as a pivot, ensuring smooth rotation. Furthermore, the connection between the positioning post and the mounting groove ensures that the pencil sharpening mechanism is confined within the housing, guaranteeing its stability and reliability. More preferably, two positioning posts are provided, distributed on opposite sides of the pencil sharpening mechanism, and two mounting grooves are provided, symmetrically distributed within the housing, ensuring the balance and stability of the pencil sharpening mechanism when swinging within the housing.

[0013] As an improvement, the housing is provided with an elastic element adapted to the pencil sharpening mechanism. The elastic element and the angle adjustment mechanism are distributed on opposite sides of the pencil sharpening mechanism, and the elastic element abuts against the pencil sharpening mechanism. In this technical solution, an elastic element is installed inside the housing. This elastic element abuts against the pencil sharpening mechanism and provides a certain elastic support after the pencil sharpening mechanism swings. The elastic element, in conjunction with the adjustment mechanism, can position the pencil sharpening mechanism after it swings, making the pencil sharpening mechanism more stable during angle adjustment and reducing swinging or displacement caused by external forces or vibrations. Furthermore, the elastic element and the angle adjustment mechanism are distributed on opposite sides of the pencil sharpening mechanism. The elastic element enables the pencil sharpening mechanism to maintain its connection with the angle adjustment mechanism. The elastic element provides elastic support when the pencil sharpening mechanism swings, making the pencil sharpening mechanism more stable during angle adjustment and ensuring smoother and more stable movement. When the pencil sharpening mechanism swings to a specific position under the action of the angle adjustment mechanism, the elastic element provides elastic force to keep the pencil sharpening mechanism stably in that position, preventing swinging or displacement caused by external forces or vibrations. The elastic element can also provide an automatic reset function, allowing the pencil sharpening mechanism to automatically return to the initial position after angle adjustment, reducing the user's operation steps.

[0014] As an improvement, the housing is provided with a limiting groove adapted to the elastic element. One end of the elastic element is connected to the limiting groove, and the other end of the elastic element abuts against the pencil sharpening mechanism. In this technical solution, the connection between one end of the elastic element and the limiting groove ensures that the elastic element is fixedly installed in the housing, ensuring its stability during operation. The abutment between the other end of the elastic element and the pencil sharpening mechanism provides elastic support, ensuring that the pencil sharpening mechanism can maintain its connection and cooperation with the angle adjustment mechanism during the swinging process, thereby improving pencil sharpening efficiency.

[0015] As an improvement, the pencil sharpening mechanism includes a blade holder and a blade mounted on the blade holder. The blade holder has a second pen inlet communicating with the first pen inlet, and the second pen inlet has an oblong shape. In this technical solution, the blade holder is the main supporting component of the pencil sharpening mechanism, used to fix the blade and allow the pen to be inserted. The blade holder has a second pen inlet communicating with the first pen inlet on the housing, used to guide the pen into the pencil sharpening mechanism. The second pen inlet has an oblong shape, with a certain length and width, which can provide a larger pen insertion space. The oblong shape of the second pen inlet can better adapt to the movable pen insertion mechanism. When the position of the pen insertion mechanism is adjusted, the pen can still pass smoothly through the first and second pen inlets and be inserted into the pencil sharpening mechanism, ensuring the stability and reliability of the pen insertion process. Even if the position of the pen insertion mechanism changes, it will not affect the insertion of the pen, providing a more flexible pen insertion channel. Attached Figure Description

[0025] like Figures 1 to 4 As shown, this application discloses a pencil sharpener, including a housing 1 and a pencil sharpening mechanism 2. The housing 1 is provided with a first pen inlet 11 communicating with the pencil sharpening mechanism 2. The first pen inlet 11 is mainly used to insert the pen to be sharpened. The pen passes through the first pen inlet 11 and is inserted into the pencil sharpening mechanism 2 for sharpening. The pencil sharpening mechanism 2 is movably installed in the housing 1. The housing 1 is also equipped with an angle adjustment mechanism 3, which is connected to the pencil sharpening mechanism 2. The angle adjustment mechanism 3 is used to drive the pencil sharpening mechanism 2 to move within the housing 1. The pencil sharpening mechanism 2 adjusts the communication angle with the first pen inlet 11 by moving within the housing 1. The movable pencil sharpening mechanism 2 changes its communication angle with the first pen inlet 11 by moving, thereby changing the pencil sharpening angle. To meet the sharpening needs of different pen types, an angle adjustment mechanism 3 is added to the housing 1. This mechanism is connected to the sharpening mechanism 2. Driven by the angle adjustment mechanism 3, the sharpening mechanism 2 can be positioned within the housing 1, thereby changing its relative angle with the first pen inlet 11. This allows the sharpener to adjust the sharpening angle according to different pen types (such as writing pencils, sketching pens, and drawing pens). Users do not need to change to different types of sharpeners or manually adjust the sharpening method; they only need to apply force to the angle adjustment mechanism 3 to adjust the sharpening angle, greatly improving ease of use. This sharpener can simultaneously sharpen multiple pen types, improving work efficiency and reducing operating costs.

[0026] More specifically, such as Figure 2 and Figure 3As shown, the angle adjustment mechanism 3 includes a push button 31 and an adjusting member 32. The push button 31 is slidably mounted on the housing 1, and the adjusting member 32 is connected to the pencil sharpening mechanism 2. When the push button 31 is slid under force, the push button 31 drives the adjusting member 32 to slide synchronously. The adjusting member 32 drives the pencil sharpening mechanism 2 to swing within the housing 1 by sliding, thereby adjusting the communication angle between the pencil sharpening mechanism 2 and the first pen inlet 11. The push button 31 serves as the direct component for user operation. The push button 31 is slidably mounted on the housing 1 and connected to the adjusting member 32. The user can apply force to the push button 31 to make the push button 31 drive the adjusting member 32 to slide synchronously. The adjusting member 32 is connected to the pencil sharpening mechanism 2 and plays the role of transmitting force, ensuring that the sliding of the push button 31 can be converted into the swing of the pencil sharpening mechanism 2, thereby realizing the adjustment of the pencil sharpening angle. The user only needs to push the push button 31 to adjust the pencil sharpening angle. The operation is intuitive and simple. The sliding design of the push button 31 makes the angle adjustment process fast and continuous, improving work efficiency.

[0027] More specifically, such as Figure 2 and Figure 3 As shown, the housing 1 is provided with a first sliding groove 12 for slidingly mounting the push button 31. The push button 31 is provided with a connecting rod 311, which passes through the first sliding groove 12 and connects to the adjusting member 32. The first sliding groove 12 provides a fixed sliding path for the push button 31, ensuring that the push button 31 remains stable during sliding and avoiding deviation or jamming caused by external force. The push button 31 is connected to the adjusting member 32 through the connecting rod 311 to transmit the sliding action of the push button 31, so that the push button 31 and the adjusting member 32 can slide synchronously to realize the adjustment of the pencil sharpening angle. The connection method is simple and the sliding is smoother and more reliable. The housing 1 is provided with a second sliding groove 13 for slidingly mounting the adjusting member 32. The second sliding groove 13 provides a fixed sliding path for the adjusting member 32, ensuring that the adjusting member 32 remains stable during sliding and avoiding deviation or jamming caused by external force.

[0028] More specifically, such as Figure 2 and Figure 3 As shown, the pencil sharpening mechanism 2 is provided with a linkage protrusion 21, and the adjusting member 32 is connected to the linkage protrusion 21. The adjusting member 32 slides on the linkage protrusion 21 to make the pencil sharpening mechanism 2 swing. The pencil sharpening mechanism 2 is mechanically linked with the adjusting member 32 by setting the linkage protrusion 21. The sliding action of the adjusting member 32 is applied to the pencil sharpening mechanism 2 through the linkage protrusion 21, making the pencil sharpening mechanism 2 swing within the housing 1. The drive is more reliable and efficient. The connection between the adjusting member 32 and the linkage protrusion 21 can be direct contact or indirect connection through other intermediate parts to ensure that the sliding of the adjusting member 32 can be effectively transmitted to the pencil sharpening mechanism 2. The design of the linkage protrusion 21 makes the swing of the pencil sharpening mechanism 2 more stable and precise.

[0029] More specifically, such as Figure 2 and Figure 3 As shown, the adjusting member 32 is provided with multiple adjustment positions 321. The adjustment positions 321 are connected to the linkage protrusion 21 to position the pen sharpening mechanism 2. The adjusting member 32 can switch between different adjustment positions 321 and the linkage protrusion 21 by sliding. The adjustment positions 321 are positioning points used to control the swing of the pen sharpening mechanism 2. Each position corresponds to a specific pen sharpening angle to ensure the consistency of the pen tip each time it is sharpened. By connecting the adjustment positions 321 with the linkage protrusion 21, the pen sharpening mechanism 2 can be driven and positioned. The user can switch between different adjustment positions 321 by sliding the adjusting member 32. The operation is simple and intuitive. Users can quickly select the appropriate sharpening angle as needed. When the adjusting piece 32 slides, different adjustment positions 321 are sequentially connected to the linkage protrusion 21, thereby causing the sharpening mechanism 2 to swing to different positions within the housing 1, thus adjusting the sharpening angle. Furthermore, when the adjusting piece 32 is not subjected to the force of the push button 31, the adjustment position 321 can abut against the linkage protrusion 21, thereby positioning the sharpening mechanism 2. This ensures that the sharpening mechanism 2 can be stably positioned at each position, reducing problems such as lead breakage or uneven sharpening caused by unstable angles during sharpening.

[0030] More specifically, such as Figures 2 to 4 As shown, multiple adjustment positions 321 are connected sequentially along an oblique direction. The adjustment positions 321 have a stepped structure, and the linkage protrusion 21 has a cylindrical structure. The sequential connection of multiple adjustment positions 321 along an oblique direction forms a stepped structure, allowing the linkage protrusion 21 to switch between different oblique positions. The contact between each adjustment position 321 and the linkage protrusion 21 is different, creating a clear sense of layering, thereby achieving adjustment of the sharpening angle. Each adjustment position 321 corresponds to a fixed sharpening angle, ensuring that the sharpening mechanism 2 operates smoothly during oscillation. During the process, it can accurately stop at the predetermined position, thereby achieving precise angle adjustment. The stepped structure allows the pencil sharpening mechanism 2 to be positioned more stably when switching gears. Furthermore, the linkage protrusion 21 is set in a cylindrical structure, which gives the linkage protrusion 21 good contact stability and movement flexibility when connected with the adjustment gear 321. The cylindrical linkage protrusion 21 and the adjustment gear 321 form a tangential relationship, ensuring that the linkage protrusion 21 can smoothly switch between different gears during the sliding process of the adjustment component 32, thereby improving the efficiency of use.

[0031] More specifically, such as Figure 2 and Figure 4As shown, the adjusting member 32 is provided with an elastic positioning structure 322, and the housing 1 is provided with multiple positioning grooves 14. The elastic positioning structure 322 abuts against the positioning grooves 14 to allow the adjusting member 32 to slide and be positioned. The adjusting member 32 slides under force to allow the elastic positioning structure 322 to switch and connect to different positioning grooves 14. The elastic positioning structure 322 is provided on the adjusting member 32. The elastic positioning structure 322 has elastic force and can abut against the positioning grooves 14 in the housing 1. The elastic positioning structure 322 achieves stable positioning of the adjusting member 32 at different positions by abutting against different positioning grooves 14. When the adjusting member 32 slides under the force of the push button 31, the elastic positioning structure 322 disengages from one positioning groove 14 and enters the next positioning groove 14 under the action of elastic force, thereby realizing the adjustment of the position of the pencil sharpening mechanism 2. Multiple positioning slots 14 are provided inside the body 1. These positioning slots 14 are distributed along the sliding direction of the adjusting member 32. Each positioning slot 14 corresponds to a specific sharpening angle. The positioning slots 14 provide positioning points for the elastic positioning structure 322, ensuring that the adjusting member 32 can stay stably in each position. By switching different positioning slots 14, the user can accurately select the sharpening angle. The user applies force to slide the push button 31 to switch the elastic positioning structure 322 between different positioning slots 14. Each positioning slot 14 corresponds to a fixed sharpening angle, ensuring the consistency of the pen tip each time and improving the sharpening quality. It should be noted that the elastic positioning structure 322 can specifically be an elastic arm structure with a positioning block. The elastic positioning structure 322 can also be set on the push button 31. The principle is the same, and it will not be described again.

[0032] More specifically, such as Figures 2 to 4 As shown, the pencil sharpening mechanism 2 is provided with a positioning post 22, and the inner wall of the housing 1 is provided with a mounting groove 15 that is adapted to the positioning post 22. The positioning post 22 and the mounting groove 15 are rotatably connected so that the pencil sharpening mechanism 2 can swing back and forth within the housing 1. The positioning post 22 and the mounting groove 15 are rotatably connected, allowing the pencil sharpening mechanism 2 to swing back and forth within the housing 1, so that the pencil sharpening mechanism 2 can adjust its angle within the housing 1 by swinging. The positioning post 22 acts as a pivot, ensuring smooth rotation. Furthermore, the connection between the positioning post 22 and the mounting groove 15 limits the installation of the pencil sharpening mechanism 2 within the housing 1, ensuring the stability and reliability of the pencil sharpening mechanism 2 in use. More preferably, there are two positioning posts 22, which are distributed on opposite sides of the pencil sharpening mechanism 2, and two mounting grooves 15, which are symmetrically distributed within the housing 1, ensuring the balance and stability of the pencil sharpening mechanism 2 when swinging within the housing 1.

[0033] More specifically, such as Figure 2 and Figure 3As shown, the housing 1 contains an elastic element 4 adapted to the pencil sharpening mechanism 2. The elastic element 4 and the angle adjustment mechanism 3 are distributed on opposite sides of the pencil sharpening mechanism 2. The elastic element 4 abuts against the pencil sharpening mechanism 2. The elastic element 4, which abuts against the pencil sharpening mechanism 2, can provide a certain elastic support after the pencil sharpening mechanism 2 swings. The elastic element 4, in cooperation with the adjustment mechanism, can position the pencil sharpening mechanism 2 after it swings, making the pencil sharpening mechanism 2 more stable during angle adjustment and reducing the swinging or displacement caused by external forces or vibrations. Furthermore, the elastic element 4 and the angle adjustment mechanism 3 are distributed on opposite sides of the pencil sharpening mechanism 2, and the elastic element 4 can... The pencil sharpening mechanism 2 is kept connected and coordinated with the angle adjustment mechanism 3. The elastic element 4 provides elastic support when the pencil sharpening mechanism 2 swings, making the pencil sharpening mechanism 2 more stable during the angle adjustment process and ensuring that the movement of the pencil sharpening mechanism 2 is more stable and smooth. When the pencil sharpening mechanism 2 swings to a specific position under the action of the angle adjustment mechanism 3, the elastic element 4 provides elastic force to make the pencil sharpening mechanism 2 stay stably in that position, preventing swinging or displacement caused by external force or vibration. The elastic element 4 can also provide an automatic reset function, so that the pencil sharpening mechanism 2 can automatically return to the initial position after the angle adjustment is completed, reducing the user's operation steps.

[0034] More specifically, such as Figure 2 and Figure 3 As shown, a limiting groove 16 adapted to the elastic element 4 is provided inside the housing 1. One end of the elastic element 4 is connected to the limiting groove 16, and the other end of the elastic element 4 abuts against the pencil sharpening mechanism 2. The connection between one end of the elastic element 4 and the limiting groove 16 makes the elastic element 4 fixedly installed inside the housing 1, ensuring that it remains stable during operation. The other end of the elastic element 4 abuts against the pencil sharpening mechanism 2, providing elastic support, ensuring that the pencil sharpening mechanism 2 can maintain its connection and cooperation with the angle adjustment mechanism 3 during the swinging process, thereby improving the pencil sharpening efficiency.

[0035] More specifically, such as Figure 2 and Figure 3As shown, the pencil sharpening mechanism 2 includes a blade holder 23 and a blade 24 mounted on the blade holder 23. The blade holder 23 is provided with a second pen inlet 231 that communicates with the first pen inlet 11. The second pen inlet 231 has an oblong hole structure. The blade holder 23 is the main supporting component of the pencil sharpening mechanism 2, used to fix the blade 24 and allow the pen to be inserted. The second pen inlet 231 on the blade holder 23 communicates with the first pen inlet 11 on the housing 1 and is used to guide the pen into the pencil sharpening mechanism 2. The oblong hole structure of the second pen inlet 231 has a certain length and width, which can provide a larger pen insertion space. The oblong hole structure of the second pen inlet 231 can better adapt to the movable pen insertion mechanism. When the position of the pen insertion mechanism is adjusted, the pen can still pass smoothly through the first pen inlet 11 and the second pen inlet 231 and be inserted into the pencil sharpening mechanism 2, ensuring the stability and reliability of the pen insertion process. Even when the position of the pen insertion mechanism changes, it will not affect the insertion of the pen, providing a more flexible pen insertion channel.

[0036] This application is not limited to the above-described preferred embodiments. Anyone can derive other products in various forms under the guidance of this application. However, regardless of any changes made to their shape or structure, any technical solution that is the same as or similar to that of this application falls within the protection scope of this application.
