Abstract
Description
Technical Field
[0001] This utility model relates to a pencil sharpener, and more particularly to a folding structure for the operating handle of a manual pencil sharpener. Background Technology
[0002] Manual pencil sharpeners are a common tool in everyday stationery. Their core structure includes a housing and an operating handle exposed outside the housing. Inside the housing are a pencil feed component for guiding the pencil in and a cutting component for cutting the pencil. All components work together to achieve the pencil sharpening function.
[0003] The operating handle is the key component driving the pencil sharpening action. Its structure consists of three parts: a connecting part, a crank part, and a grip. Specifically, the connecting part extends into the pencil sharpener housing and is securely connected to the end of the blade holder inside the housing via threads. This connection method ensures that the operating handle effectively drives the blade holder to rotate synchronously when rotated. The crank part forms a 90-degree angle with the connecting part, providing a reasonable lever structure for force transmission. The grip also forms a 90-degree angle with the crank part, making it convenient for the user to hold and apply rotational force. Through this structural design, the operating handle can smoothly drive the blade holder to rotate, completing the cutting action.
[0004] However, the existing operating handle structure has obvious defects. Due to the 90-degree angle formed between the connecting part, the crank part, and the grip, the operating handle has an irregular three-dimensional shape. This irregular shape directly leads to a series of problems: when placed, the operating handle protrudes outward, making it impossible for the pencil sharpener to maintain a neat outline, and making it difficult to place stably or store neatly with other stationery; during packaging, the protruding operating handle occupies a lot of extra space, increasing the amount of packaging materials used and transportation costs; more importantly, from an aesthetic design perspective, this abrupt irregular structure disrupts the overall harmony and aesthetics of the pencil sharpener, reducing the product's visual appeal. Utility Model Content

[0019] The front end of the housing is provided with a pencil inlet hole for inserting a pencil, and the drive unit is fixedly connected to the rear end of the housing; inside the housing, a pencil inlet assembly and a cutting assembly are installed sequentially from the front end to the rear end. The cutting assembly includes a hob and a tool holder for fixing and supporting the hob. The drive unit is assembled with the rear end of the tool holder by a threaded connection.
[0020] A groove is provided on the rear side of the drive unit, which is used to fold the operating handle when not in use; when the pencil sharpener is needed, the operating handle can be unfolded from the groove, and the cutting component can be driven by hand-cranking the operating handle to perform pencil cutting.
[0021] A further preferred technical solution of this utility model is: the operating handle adopts a foldable structure, specifically including a rocker arm and a hand-held part, wherein the first end of the rocker arm is hinged to one end of the groove through a shaft connection component, so that the rocker arm can rotate around the shaft connection point as the rotation center;
[0022] When not in use, the rocker arm can rotate around the aforementioned shaft contact and be fully positioned within the groove;
[0023] In addition, the rocker arm is provided with a receiving groove, and one end of the hand-held part is hinged to one end of the receiving groove through a shaft connection component, thereby giving the hand-held part a degree of freedom to rotate relative to the rocker arm; thus, when not in use, the hand-held part can rotate around its shaft connection point with the receiving groove and be stored in the receiving groove.
[0024] A further preferred embodiment of this utility model is as follows: a concave-convex positioning structure is provided between the rocker arm and the groove to maintain the folded state of the rocker arm; the cross-section of the rocker arm is U-shaped.
[0025] Another technical topic: a folding structure for the operating handle of a manual pencil sharpener, which mainly consists of three parts: a housing, a drive unit, and an operating handle; wherein the operating handle is mounted and connected to the drive unit;
[0026] The operating handle includes a rocker arm and a hand-held part. The hand-held part is hinged to the rocker arm, and the rocker arm is provided with a receiving groove. The hand-held part can be folded into the receiving groove.

[0030] Another technical subject: a pencil sharpener, including the aforementioned folding mechanism for the operating handle.
[0031] Compared with existing technologies, the advantages of this invention are: by designing the drive unit in a cylindrical shape and matching its diameter with that of the cylindrical shell, the two combine to form a complete cylinder. The matching diameter of the drive unit with the cylindrical shell, and its assembly with the cutting assembly's tool holder via a threaded connection, ensures a tight connection between the components and improves the overall structural stability.

This technology not only improves the user experience but also reduces the risk of damage caused by inconvenient operation. Users can prepare and store the pencil sharpener without complicated procedures.
[0033] This invention significantly improves the overall performance of a manual pencil sharpener by optimizing the structural design of the cylindrical shell and drive unit, as well as the folding function of the operating handle. It not only optimizes space utilization and appearance design but also enhances operational convenience and user experience. Furthermore, by strengthening structural stability and durability, this invention further extends the lifespan of the pencil sharpener, making it more competitive in the market.

[0046] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.
[0047] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.
[0048] like Figures 1 to 7 As shown, this utility model relates to a folding structure 100 for the operating handle of a manual pencil sharpener. This structure mainly consists of three parts: a cylindrical housing 10, a drive unit 20, and an operating handle 30. The operating handle 30 is mounted and connected to the drive unit 20 via a specific connection structure. This connection method not only ensures the stability of the operating handle 30 during use but also enables it to fold when not in use, thereby optimizing the overall structural layout of the pencil sharpener.
[0049] It should be noted that the annular wall structure design of the drive unit 20 allows for direct user operation, providing not only a good grip but also increased operational stability. Furthermore, the operating handle 30 is connected to the drive unit 20 via its unique folding structure, enabling users to operate the drive unit 20 with greater ease.
[0050] The overall structure of the cylindrical housing 10 is cylindrical. This shape not only gives the pencil sharpener a simple and neat appearance, but also provides reasonable space for the layout of the internal components. On its front face, there is a pencil inlet hole 11 for inserting a pencil. The size and shape of the pencil inlet hole 11 are precisely calculated to accommodate pencils of various diameters, ensuring that the pencil can be inserted stably and smoothly and guided to the cutting component.
[0051] The drive unit 20 is fixedly connected to the rear end face of the cylindrical housing 10. This connection method ensures the structural stability between the drive unit 20 and the cylindrical housing 10, allowing the entire pencil sharpener to maintain good integrity during use. Simultaneously, the fixed connection between the drive unit 20 and the rear end face of the cylindrical housing 10 provides sufficient space for the folding structure of the operating handle 30. This allows the operating handle 30 to be completely folded into the groove 21 of the drive unit 20 when not in use, achieving compact storage of the pencil sharpener when not in use and further optimizing the product's portability and aesthetics.
[0052] In summary, this combination of the cylindrical housing 10 and the drive unit 20 provides a closed and stable operating environment for the internal components of the pencil sharpener. Inside the cylindrical housing 10, the pencil feeding assembly 101 and the cutting assembly 102 are installed sequentially from front to rear. This layout allows the pencil to smoothly enter the cutting assembly 102 along a preset path after being inserted into the pencil feeding hole 11, thus achieving efficient pencil sharpening. Simultaneously, the drive unit 20 and the blade holder 13 of the cutting assembly 102 are assembled via a threaded connection. This connection method not only ensures effective power transmission but also facilitates user disassembly and maintenance of the cutting assembly 102, further improving the lifespan of the pencil sharpener and the user experience.
[0053] like Figure 3 , Figure 6 and Figure 8 The components inside the cylindrical housing 10 shown are arranged from front to back as a pencil feeding assembly 101 and a cutting assembly 102. This layout not only makes efficient use of space but also ensures that the pencil can smoothly enter the cutting assembly 102 along a preset path after insertion, thereby achieving efficient pencil sharpening.
[0054] The pencil feed assembly 101 is located at the front end of the cylindrical housing 10, and its main function is to guide the pencil into the pencil sharpener. The design of the pencil feed assembly 101 takes into account the compatibility of pencils of different diameters. Through its internal guiding structure, it can ensure that the pencil can be stably guided to the cutting assembly 102 after insertion.
[0055] The cutting assembly 102 is located at the rear end of the cylindrical housing 10 and is the core component of the pencil sharpener. The cutting assembly 102 includes a hob 12 and a tool holder 13 for fixing and supporting the hob 12.
[0056] Furthermore, the drive unit 20 is assembled to the rear end of the tool holder 13 via a threaded connection. This threaded connection ensures a tight connection between the drive unit 20 and the tool holder 13, thereby providing stable power transmission during cutting. This connection method not only withstands large cutting forces but also ensures the reliability of the cutting assembly 102 during long-term use.
[0057] The cylindrical housing 10 features a compact internal layout and tight connections between components, making the entire pencil sharpener small in size and easy to carry and store. Furthermore, the simple and elegant exterior design of the cylindrical housing 10 complements the ingenious design of the internal components, enhancing the overall aesthetics of the product.
[0058] The drive unit 20 is cylindrical, and the diameter of the cylindrical housing 10 matches the diameter of the drive unit 20, forming a complete cylinder when combined. This makes the overall appearance of the pencil sharpener more regular and uniform. This design not only enhances the product's aesthetics but also makes it visually simpler and more harmonious. The regular cylindrical structure makes the pencil sharpener easier to place and store. It adapts better to various desktop environments, remaining stable and not taking up too much space whether placed on a desk, office desk, or other narrow space.
[0059] Furthermore, the cylindrical drive unit 20 matches the diameter of the cylindrical housing 10, ensuring a tighter and more stable connection between the two. The annular wall structure design of the drive unit 20 allows the user to hold the pencil sharpener more naturally during operation, providing a good grip.
[0060] More importantly, the diameter of the drive unit 20 matches that of the cylindrical housing 10, allowing the user to apply force more stably during operation, thereby improving the efficiency and quality of pencil sharpening. The regular cylindrical structure allows the pencil sharpener to be placed more compactly during packaging, reducing the amount of packaging material used. This not only reduces packaging costs but also reduces space occupation during transportation, thus lowering transportation costs.
[0061] More specifically, a specially designed groove 21 is provided on the rear side of the drive unit 20. The main function of this groove 21 is to provide a storage location for the operating handle 30 when the pencil sharpener is not in use. This technology allows the operating handle 30 to be completely folded and stored in the groove 21, thus maintaining the overall neatness and aesthetics of the pencil sharpener. When the user needs to use the pencil sharpener, the operating handle 30 can be easily unfolded from the groove 21, and the cutting assembly 102 can be driven by hand-cranking the operating handle 30 to perform pencil cutting.
[0062] The design of the groove 21 allows the operating handle 30 to be completely folded and stored when not in use, greatly reducing the overall size of the pencil sharpener. When the operating handle 30 is folded into the groove 21, the overall appearance of the pencil sharpener is more neat and aesthetically pleasing.
[0063] like Figure 10 As shown, specifically, the operating handle 30 consists of two main parts: a rocker arm 31 and a handheld part 32. The first end of the rocker arm 31 is hinged to one end of the groove 21 on the rear side of the drive part 20 via a shaft connection member k. This hinged technology allows the rocker arm 31 to rotate around the shaft connection point as the center of rotation, thereby realizing its folding and unfolding actions.
[0064] When not in use, the rocker arm 31 can rotate around the shaft contact point and be completely retracted into the groove 21, making the overall appearance of the pencil sharpener more neat and aesthetically pleasing. In addition, a receiving groove h is specially designed on the rocker arm 31, such as... Figure 9 As shown, one end of the handle 32 is hinged to one end of the receiving groove h via a shaft connection member k', which gives the handle 32 a degree of rotational freedom relative to the rocker arm 31. Therefore, in the non-use state, the handle 32 can rotate about its shaft connection point with the receiving groove h and eventually be stored in the receiving groove h, further reducing the space occupied by the operating handle 30 when stored.
[0065] The folding and unfolding process of the operating handle 30 is very simple and quick. Moreover, the foldable design of the operating handle 30 significantly reduces its space occupation when not in use. The double folding structure of the rocker arm 31 and the handheld part 32 allows the operating handle 30 to be completely stored in the groove 21 of the drive part 20, thereby greatly reducing the overall size of the pencil sharpener.
[0066] By adopting a foldable structural design, the operating handle 30 not only achieves a compact storage function, but also optimizes the overall space utilization, appearance design, ease of operation, structural stability and user-friendliness of the pencil sharpener.
[0067] Preferably, such as Figure 11As shown, a concave-convex positioning structure v is provided between the rocker arm 31 and the groove 21 to maintain the folded state of the rocker arm 31. The design of the concave-convex positioning structure v ensures that the rocker arm 31 can be firmly fixed in the groove 21 after folding, preventing the rocker arm 31 from accidentally unfolding due to external collisions or vibrations. This stability is crucial for the safety of the pencil sharpener during transportation, storage, or use, avoiding potential damage or inconvenience caused by the accidental extension of the operating handle.
[0068] Moreover, the design based on the concave-convex positioning structure v allows the operating handle 30 to fit tightly into the groove 21 after folding, reducing the accumulation of dust and pencil shavings.
[0069] Preferably, the rocker arm 31 has a U-shaped cross-section. The U-shaped cross-section of the rocker arm 31 has higher bending and torsional resistance, making the rocker arm 31 more stable during folding and unfolding. Moreover, it does not prevent it from forming the receiving groove h for accommodating the handheld part 32.
[0070] Preferably, the cylindrical shell 10 has a protruding structure g on its peripheral side, the protruding structure g having a flat surface g1 for easy placement. This provides a stable placement surface, allowing the pencil sharpener to be placed more stably on various surfaces during use or storage.
