Abstract
Description
Technical Field
[0001] This utility model relates to the field of stationery and school supplies technology, specifically to a decorative pencil sharpener that is easy to manufacture, has an excellent product appearance, and a pleasing visual effect. Background Technology
[0002] Manual pencil sharpeners are widely used educational tools. Their main structure consists of a sharpening mechanism within the main body. This mechanism has a conical tube with a blade at its edge. When a pencil is inserted into the conical tube and rotated to contact the blade, it is sharpened into a conical shape for easier writing. It is known that, to facilitate the collection and storage of residual wood shavings and lead powder generated during pencil sharpening, it is desirable to house the main body within an outer shell that forms a shavings collection cavity or storage chamber.
[0003] Since the majority of users of pencil sharpeners are primary school students, the overall appearance of the pencil sharpener is also a major factor in their purchasing decisions. Based on this, those skilled in the art often consider the shape of the pencil sharpener's outer shell and the design of additional decorative parts. It is known that, to facilitate the assembly of the pencil sharpener and the shaping of the shell, the traditional approach is to manufacture the pencil sharpener shell through injection molding or mold making. For example, Chinese Utility Model Patent Publication No. CN208914860U discloses a decorative part mounting structure and a pencil sharpener, in which the decorative part can be detachably installed on the plastic pencil sharpener shell, and the overall external shape of the pencil sharpener can be changed by replacing the decorative part.
[0004] However, since the shells of pencil sharpeners are made by injection molding or mold making, although there is a wide variety of product shapes, the plastic itself is difficult to color or print patterns after it hardens. This means that while the shapes of known pencil sharpeners made of plastic shells are varied, pencil sharpeners from the same manufacturer are basically rigid or identical in terms of color or style design. As a result, they cannot meet consumers' diverse aesthetic needs and their ever-increasing demands for product quality.
[0005] For plastic shells, the manufacturing process requires melting or plasticizing the masterbatch, then injecting it into the mold cavity at a certain pressure and rate using an injection molding machine. After cooling and solidification, the product is obtained. Therefore, there is room for improvement in manufacturing costs and time.
[0006] Meanwhile, for the sake of overall appearance consistency and to prevent the pencil sharpener from being affected by the external environment, manual pencil sharpeners generally include a top cover and a main body with the pencil sharpener inside. The top cover and the main body can be designed to fit each other in shape or snap together to switch between closed and open states, or the top cover and the main body can be connected together by a pivot hinge.
[0007] Regarding the former, since the top cover and the main body are two independent and detachable parts, the loss of the top cover can easily lead to the pencil sharpener losing its protective and overall aesthetic functions. For the latter, while the hinged connection effectively prevents the top cover from being lost, it is a situation that needs improvement from a manufacturing and product assembly cost perspective, as relatively expensive tooling technology is required to implement the hinge. Furthermore, the corresponding hinge may sometimes contradict the visually appealing overall appearance of the pencil sharpener, as a prominently exposed hinge does not match the overall shape or aesthetic pattern of the pencil sharpener. Finally, due to the instability of the hinge, it can break or tear and cannot be replaced in case of damage.
[0008] Therefore, there is a technical need in the relevant technical field to improve existing pencil sharpeners to solve the above-mentioned shortcomings. Utility Model Content
[0009] Therefore, the objective of this invention is to provide a decorative pencil sharpener, thereby overcoming the shortcomings of the prior art.
[0010] According to one aspect of the present invention, a decorative pencil sharpener is provided, comprising: a top cover formed by stamping a metal material; a body made of injection molding or thermoplastic material, wherein the body includes a rectangular top located at the top and side peripheral portions extending downward from the top along its outer periphery; a pencil sharpening portion made of injection molding or thermoplastic material; and a housing having a chip collection cavity located below the pencil sharpening portion, wherein the housing is formed by stamping a metal material; wherein the top of the body is further provided with a slide portion spaced apart from the pencil sharpening portion, wherein the slide portion is higher than the pencil sharpening portion by a predetermined distance and has guide rail portions arranged on opposite sides thereof, wherein the guide rail portions are designed to fit the shape of the top cover and guide it to slide horizontally relative to the top of the body.
[0011] Unlike existing decorative pencil sharpeners, the main parts of this invention, which are directly visible to the consumer, are all made of a stamped shell that can be metal-printed. When combined with the design of the stamped shell itself, the colors and patterns printed on it achieve a visual aesthetic that is impossible in existing pencil sharpeners. Furthermore, since the decorative pencil sharpener is assembled using a metal-printed stamped shell, this does not substantially increase the process or material costs in the pencil sharpener manufacturing process. Therefore, the decorative pencil sharpener of this invention has considerable economic and commercial value.
[0012] As a preferred aspect of the present invention, it further includes engaging portions located on opposite sides of the side periphery of the main body, wherein the engaging portions protrude outward from the side periphery by a predetermined distance and are spaced apart from the top of the main body located above it by a certain distance, so as to form a shape fit with the housing.

[0015] As a preferred aspect of the present invention, the engaging portions on opposite sides of the main body are substantially parallel to the guide rail portions on opposite sides of the slide portion.
[0016] As another aspect of this utility model, another decorative pencil sharpener is also included, comprising: a top cover formed by stamping a metal material; a snap plate fitted into the top cover in a shaped fit, wherein the snap plate has a snap-fit hole; a body made of injection-molded or thermoplastic material, wherein the body includes a top portion located above and a side portion extending downward from the top along its outer periphery; a pencil sharpening portion made of injection-molded or thermoplastic material; and a housing having a chip collection cavity located below the pencil sharpening portion, wherein the housing is formed by stamping a metal material; wherein the top of the body is further provided with a pivot portion spaced apart from the pencil sharpening portion, wherein the pivot portion is higher than the pencil sharpening portion by a predetermined distance and has a pair of snap-fit portions arranged on its outer periphery, wherein the snap-fit portions are designed to engage with the snap-fit hole when the pivot portion is located in the snap-fit hole, so as to allow the top cover and the snap plate to rotate relative to the top of the body.
[0017] As a preferred aspect of the present invention, the buckle plate further has guide posts arranged adjacent to the snap-fit holes and a fan-shaped guide groove portion surrounding the pivot portion on the top of the main body, wherein the guide posts can be inserted into the guide groove portion during the rotational movement of the upper cover.
[0018] As a preferred aspect of the present invention, the two ends of the guide groove are provided with a pair of stop portions for limiting the maximum rotational position of the top cover and the buckle plate.
[0019] As a preferred aspect of the present invention, it further includes engaging portions located on opposite sides of the side periphery of the main body, wherein the engaging portions protrude outward from the side periphery by a predetermined distance and are spaced apart from the top of the main body located above it by a certain distance, so as to form a shape fit with the housing.
[0020] As a preferred aspect of the present invention, at least one of the top cover and the housing has a patterned layer printed with thermosetting ink on its outermost side.

[0041] To provide a better understanding of the purpose, structure, features, and functions of this utility model, a detailed description of several embodiments is provided below.
[0042] First Embodiment
[0043] First, combine Figures 1 to 4 The first embodiment of the decorative pencil sharpener 100 according to the present invention is described, wherein the decorative pencil sharpener 100 is in an exploded state in these views.
[0044] like Figures 1 to 4 As shown, this decorative pencil sharpener 100 includes at least Figure 1 Arranged from top to bottom: an upper cover 11, which may be a thin shell made of a metal sheet or plate with a certain degree of toughness by stamping; a main body 12 made of injection molded or thermoplastic material; a brush-twisting part 14 also preferably made of injection molded or thermoplastic material; and a stamped shell 13 located below the main body 12, defining a shavings collection cavity 13A for collecting shavings from the brush-twisting part 14. These components will be described in detail below.
[0045] like Figures 1 to 3 As best illustrated, the body 12 is designed as a cylindrical body with, for example, a generally rectangular cross-section and rounded edges. That is, the body 12 includes a rectangular top and side portions extending downwards from the top along its rectangular periphery, wherein the cylindrical body with the rectangular cross-section is rounded near its four corners. To prevent the tipping portion 14 from rotating into the body 12, an accommodating cavity for receiving the tipping portion 14 is exemplary formed in a region at one corner of the top of the body 12, such as... Figure 1 and 3 As shown. The receiving cavity has a generally rectangular insertion port located at the top of the main body 12, and a support portion extending downward from the main body 12 from the insertion port to support the pen-grinding part 14.
[0046] Furthermore, such as Figure 1 and 3 As shown, engaging portions 12B, preferably strip-shaped protrusions, are preferably provided on opposite sides of the side periphery of the main body 12, for example in... Figure 4 The left and right sides of the body are provided with two, preferably strip-shaped, protruding engaging portions 12B, which protrude outward from the periphery by a predetermined distance and are spaced apart from the top of the main body 12 above them. Preferably, the top of the main body 12 is designed to be made of a transparent or light-transmitting injection-molded or thermoplastic material, so that primary school students or consumers can observe the cutting process of the pen-twisting part 14 and the chip removal of the pen-twisting part 14 below through the top of the main body 12.
[0047] like Figure 1 as well as Figure 3 As shown, the main structure of the pencil sharpening unit 14 includes a base with an internally conical pencil insertion cavity 14A. A groove is provided on the outer side of a predetermined portion of the pencil insertion cavity 14A to discharge pencil shavings generated during sharpening. A pencil sharpening blade 14B is fixed to the outer wall of the base adjacent to the groove, for example, by a screw connection. The cutting edge of the blade 14B is preferably designed to be located precisely at the groove. Thus, in use, for example, a primary school student simply inserts the end of the pencil (e.g., but not limited to pencils or colored pencils) into the pencil insertion cavity 14A of the pencil sharpening unit 14 and applies a certain force to rotate it relative to the blade 14B. The cutting is then performed by the cutting edge of the blade 14B adjacent to the groove. As a result, the end of the pencil (e.g., but not limited to pencils or colored pencils) is gradually sharpened into a conical shape until the consumer's desired thickness is achieved.
[0048] Furthermore, such as Figures 2 to 3 In the area shown, a slide section 12C is provided at the top of the main body 12, separated from the pen-gripping section 14, and is raised a certain distance above the pen-gripping section 14. This slide section 12C is, for example, 1 to 3 millimeters higher than the pen-insertion cavity 14A and is constructed to be substantially the same as the outer contour of the top of the main body 12, i.e., also designed as a square. On opposite sides of the slide section 12C, guide rail sections 12A, preferably strip-shaped protrusions, are provided, for example... Figure 4 The left and right sides of the slide are provided with two guide rail portions 12A, preferably strip-shaped protrusions, which extend outward from the slide portion 12C by a predetermined distance and are designed to form a shape fit with the upper cover 11 described in detail below to achieve sliding guidance of the upper cover 11. Preferably, as Figure 2 and 4 As shown, the engaging portions 12B on opposite sides of the main body 12 are generally parallel to the guide rail portions 12A on opposite sides of the slide portion 12C.
[0049] As another part of the embodiment of the decorative pencil sharpener 100, a stamped housing 13 is provided below the main body 12 for inserting the main body 12 of the decorative pencil sharpener 100 into a chip collection cavity 13A. This is different from the plastic housing made by injection molding or thermoplastic materials in the prior art. Here, the stamped housing refers to a housing made by stamping a metal sheet with a certain degree of toughness.
[0050] like Figures 1 to 4As shown, the stamped housing 13 has an outer contour conforming to the main body 12 of the decorative pencil sharpener 100, i.e., it is also designed as a hollow cuboid, for example, with a generally rectangular cross-section. The stamped housing 13 includes an outer peripheral wall conforming to the outer contour of the main body 12 and a chip collection cavity 13A enclosed by the outer peripheral wall for inserting the main body 12. The chip collection cavity 13A is located directly below the pencil sharpening portion 14 after the main body 12 is inserted, allowing pencil shavings originating from the pencil sharpening portion 14 in the main body 12 to fall into and be stored in the chip collection cavity 13A under the force of gravity. Furthermore, the uppermost edge of the outer peripheral wall is preferably designed to be flanged towards the chip collection cavity 13A to form an undercut portion for the engaging portion 12B to form a shape fit and a top edge for the side edge of the top of the main body 12 to abut.
[0051] Those skilled in the art will understand that although the main body 12 and the stamped housing 13 are separate components made of plastic and metal respectively (rather than a single piece made of plastic or a fixed connection formed by threaded parts or snap-fit joints made of plastic as in the prior art), on the one hand, both the main body 12 and the conformably shaped stamped housing 13 are non-rotationally symmetric in shape with a generally rectangular cross-section, and on the other hand, the static friction between the aforementioned engaging portion 12B and the top side edge and the stamped housing 13 allows the main body 12 to be anti-rotatedly housed within the stamped housing 13. This allows the consumer to hold the stamped housing 13 with one hand while using the decorative pencil sharpener, and use the other hand to insert the pencil to be sharpened into the anti-rotationally housed body 12 within the stamped housing 13 for pencil sharpening, without affecting the anti-rotational engagement of the main body 12 and the stamped housing 13.
[0052] Based on this, since the main part of the decorative pencil sharpener 100 of this utility model, which is directly visible to consumers, is made of a stamped shell 13 that can be printed with metallic colors, it significantly increases the designer's freedom to create or beautify the outer wall of the stamped shell 13. That is, various colors and patterns can be printed on various parts of the outer wall with virtually no restrictions. If combined with the shape design of the stamped shell 13 itself, the colors and patterns printed on the stamped shell 13 can achieve a visual aesthetic that cannot be achieved in existing pencil sharpeners.
[0053] Furthermore, the decorative pencil sharpener 100 of this utility model also has the following characteristics: Figures 1 to 4The decorative pencil sharpener 100's top cover 11, shown from various perspectives, is also a shell made of a relatively flexible metal material by stamping, and its forming method can be the same as that of the stamped shell 13. The side periphery of the top cover 11 is also flanged to form an undercut portion that conforms to the guide rail portions 12A on both sides of the slide portion 12C of the main body 12. As a result, after the main body 12 according to this invention is placed anti-rotatingly onto the stamped shell 13, the top cover 11 can be pressed onto the top of the main body 12 until the flange of the top cover 11 conforms to the guide rail portions 12A on both sides of the slide portion 12C. This ensures that the top cover 11 remains on top of the main body 12 in a way that prevents removal or loss and prevents external dust from entering the pencil insertion cavity 14A when the consumer is not using the pencil sharpener 100. Meanwhile, when a consumer needs to use the pencil sharpener 100 to sharpen a pencil, they only need to gently press the top cover 11 and apply a certain pushing force to the top cover 11 to the side, so that the top cover 11 can be smoothly moved horizontally to the position of the exposed pencil insertion cavity 14A under the guidance of the guide rail 12A. For example, in Figure 2 The position shown in the image. Next, the consumer sharpens the pencil using the pencil-grinding part 14, during which the pencil shavings fall freely into the shavings collection chamber 13A. After a certain amount of pencil shavings have accumulated, the main body 12, along with the top cover 11, is removed from the stamping housing 13 (as shown in the image). Figure 4 (As shown), empty the pencil shavings from the shavings collection chamber 13A. Then, reposition the main body 12 and the top cover 11 to return it to the state ready for the next pencil sharpening operation.
[0054] Therefore, since the top cover 11 of the aforementioned decorative pencil sharpener 100 remains effectively connected to its main body 12, there is no possibility of the top cover 11 being accidentally lost. Furthermore, the opening mechanism of the top cover 11 is simple and reliable. Horizontal movement between the top cover 11 and the main body 12 is achieved through a mechanism concealed within the top cover 11. This reduces manufacturing costs and complexity, and avoids unnecessary impact on the shape or design of the pencil sharpener 100.
[0055] Second Embodiment
[0056] Next, combine Figures 5 to 8 The second embodiment according to the present invention will now be described.
[0057] This decorative pencil sharpener 200 includes at least... Figure 5Arranged from top to bottom: an upper cover 21, which may be a shell made of a metal sheet with a certain degree of toughness by stamping; a main body 22 made of injection molded or thermoplastic material; a brush-twisting part 24 also preferably made of injection molded or thermoplastic material; and a stamped shell 23 located below the main body 22, defining a shavings collection cavity 23A for collecting shavings from the brush-twisting part 24. These components will be described in detail below.
[0058] Unlike the first embodiment, the decorative pencil sharpener 200 in the second embodiment also has a snap-on plate 25 made of injection-molded or thermoplastic material that is fitted into the upper cover 21 in a shape-fitting manner. Figure 7 As shown, the buckle plate 25 has a snap-fit hole 25A on one side, which can be designed to rotate relative to the body 22 about a pivot portion 22C of the body 22, which is described in detail below. To improve smoothness during rotation, a guide post 25B is provided adjacent to the snap-fit hole 25A, which protrudes from the buckle plate 25 toward the body 22 and can be inserted into a guide groove portion 22D in the body 22, which is described in detail below.
[0059] like Figures 5 to 8 As best shown, the main body 22 is designed as a cylindrical body with a generally gourd-shaped cross-section and a smoothly transitioned outer periphery. Specifically, the main body 22 includes a gourd-shaped top and side circumferences extending downwards from the top along its gourd-shaped outer periphery. To prevent the rotating part 24 from rotating into the main body 22, a receiving cavity is formed at one corner of the top of the main body 22 for accommodating the rotating part 24. Figure 5 and 6 As shown. The receiving cavity has a generally rectangular insertion port located at the top of the main body 22, and a support portion extending downward from the main body 22 from the insertion port to support the pen-grinding part 24.
[0060] Furthermore, such as Figure 7 and 8 As shown, engaging portions 22B, preferably strip-shaped protrusions, are preferably provided on opposite sides of the side periphery of the main body 22, for example in... Figure 7 The front and rear sides of the body are provided with two, preferably strip-shaped, protruding engaging portions 22B, which protrude outward from the periphery by a predetermined distance and are spaced apart from the top of the main body 22 above them. Preferably, the top of the main body 22 is designed to be made of a transparent or light-transmitting injection-molded or thermoplastic material, so that primary school students or consumers can observe the cutting process of the pen-twisting part 24 and the chip removal of the pen-twisting part 24 below it through the top of the main body 22.
[0061] like Figure 5 and Figure 6 As shown, the main structure of the pencil sharpening section 24 includes a base with an internally conical pencil insertion cavity 24A. A groove is provided on the outer side of a predetermined portion of the pencil insertion cavity 24A to discharge pencil shavings generated during sharpening. A sharpening blade 24B is fixed to the outer wall of the base adjacent to the groove, for example, by a screw connection. The cutting edge of the blade 24B is preferably designed to be located precisely at the groove. Thus, in use, for example, a primary school student simply inserts the end of the pencil (e.g., but not limited to pencils or colored pencils) into the pencil insertion cavity 24A of the pencil sharpening section 24, which is anti-rotatingly positioned at the top of the main body 22, and applies a certain force to rotate it relative to the blade 24B. The cutting action is then performed by the cutting edge of the blade 24B adjacent to the groove. As a result, the end of the pencil (e.g., but not limited to pencils or colored pencils) is gradually sharpened into a conical shape until the consumer's desired thickness is achieved.
[0062] Furthermore, such as Figure 5 and 7 In the central part of the diagram, a pivot portion 22C is provided in the top of the main body 22, separated from the pen insertion cavity 24A, allowing the upper cover 21 and its internal snap plate 25 to pivot about it. This allows the upper cover 21 to switch between an initial position where it is closed and coincides with the main body 22, and an open position where it is rotated away from the pen insertion cavity 24A. This switching action will be described in detail below. The pivot portion 22C can be designed as a cylinder that extends a certain distance above the pen insertion cavity 24A, wherein the outer diameter of the cylinder is approximately equal to the inner diameter of the snap-fit hole 25A in the snap plate 25. Meanwhile, in order to keep the upper cover 21 and the buckle plate 25 connected to the main body 22 at all times, the pivot portion 22C has a pair of claw portions 22A that can engage with the snap-fit hole 25A in the buckle plate 25. Thus, by means of the engagement between the claw portions 22A and the snap-fit hole 25A of the buckle plate 25, the reliable connection between the upper cover 21 and the buckle plate 25 and the main body 22 is always ensured without hindering the pivoting of the upper cover 21 and the buckle plate 25 around the pivot portion 22C.
[0063] Additionally, such as Figure 6As best shown, to reliably guide the pivoting of the cover 21 and the buckle 25, a fan-shaped guide groove 22D is provided at the top of the body 22, surrounding the pivot portion 22C. Stop portions 22E are provided at both ends of the guide groove 22D to limit the maximum rotational position of the cover 21 and the buckle 25. Specifically, when the cover 21 and the buckle 25 are fastened to the top of the body 22, as the pivot portion 22C is inserted into the snap-fit hole 25A in the buckle 25 within the cover 21 and engages with the buckle 25 via the claw portion 22A, the guide post 25B in the buckle 25 is also inserted into the guide groove 22D. The fan-shaped guide groove 22D ensures that the rotation of the cover 21 and the buckle 25 during pivoting relative to the top of the body 22 is guided and due to the limited rotational opening angle of the paired stops 22E.
[0064] As another part of the embodiment of the decorative pencil sharpener 200, a stamped housing 23 is provided below the main body 22 for inserting the main body 22 of the decorative pencil sharpener 200 into a chip collection cavity 23A. This is different from the plastic housing made by injection molding or thermoplastic materials in the prior art. Here, the stamped housing refers to a housing made by stamping a metal material with a certain toughness.
[0065] like Figures 1 to 4 As shown, the stamped housing 23 has an outer contour conforming to the main body 22 of the decorative pencil sharpener 200, i.e., it is also designed as a hollow cuboid, for example, with a generally gourd-shaped cross-section. The stamped housing 23 includes an outer peripheral wall conforming to the outer contour of the main body 22 and a chip collection cavity 23A enclosed by the outer peripheral wall for inserting the main body 22. The chip collection cavity 23A is located directly below the pencil sharpener 14 after the main body 22 is inserted, allowing pencil shavings from the pencil sharpener 14 in the main body 22 to fall into and be stored in the chip collection cavity 23A under the force of gravity. Furthermore, the uppermost edge of the outer peripheral wall is preferably designed to be flanged towards the chip collection cavity 23A to form an undercut for the engaging portion 22B to form a shape fit and a top edge for the side edge of the top of the main body 22 to abut.
[0066] Based on this, since the main part of the decorative pencil sharpener 200 that consumers can directly observe is made of a stamped shell 23 that can be printed with metallic colors, it significantly increases the designer's freedom to create or beautify the outer wall of the stamped shell 23. That is, various colors and patterns can be printed on various parts of the outer wall with virtually no restrictions. If combined with the shape design of the stamped shell 23 itself, the colors and patterns printed on the stamped shell 23 can achieve a visual aesthetic that cannot be achieved in existing pencil sharpeners.
[0067] As a result, after the main body 22 according to this invention is placed anti-rotatingly onto the stamped housing 23, the upper cover 21 and the buckle plate 25 located therein can be pressed onto the top of the main body 22 until the snap-fit hole 25A of the buckle plate 25 forms an operative connection with the pivot portion 22C and its claw portion 22A. This ensures that the upper cover 21 remains on the upper part of the main body 22 in a manner that prevents removal or loss and prevents external dust from entering the pen insertion cavity 24A when the consumer is not using the pencil sharpener 200. At the same time, when the consumer needs to use the pencil sharpener 200 for pencil sharpening, they only need to gently press the upper cover 21 and apply a certain pushing force to the upper cover 21 laterally to allow the upper cover 21 to smoothly rotate and move to the position of the exposed pen insertion cavity 24A under the guidance of the pivot portion 22 and the guide groove portion 22D. Next, the consumer sharpens the pencil using the pencil-grinding section 24. The resulting pencil shavings fall freely into the shavings collection chamber 23A. After a certain amount of shavings have accumulated, the main body 22, along with the top cover 21, is removed from the stamping housing 23 (e.g., ...). Figure 5 (As shown), empty the pencil shavings from the shavings collection chamber 23A. Then, reposition the main body 22 and the top cover 21 to return it to the state ready for the next pencil sharpening operation.
[0068] Therefore, since the top cover 21 of the aforementioned decorative pencil sharpener 200 remains effectively connected to its main body 22, there is no possibility of the top cover 21 being accidentally lost. Furthermore, the opening mechanism of the top cover 21 is simple and reliable. The rotational movement between the top cover 21 and the main body 22 is achieved through a mechanism concealed within the top cover 21. This reduces manufacturing costs and complexity, and avoids unnecessary impact on the pencil sharpener's shape or design.
[0069] As can be seen from the above, compared with the prior art, the decorative pencil sharpener according to this utility model has at least the following beneficial technical effects:
[0070] 1. Since the top cover and the main body are always connected together in this utility model, there are no shortcomings such as the loss of protection and overall aesthetic function of the pencil sharpener due to the loss of the top cover;
[0071] 2. The relative horizontal or rotational movement between the top cover and the main body is achieved by a mechanism built into the top cover. This reduces the cost and difficulty of product manufacturing and does not have an unnecessary impact on the shape or pattern of the pencil sharpener.
[0072] The preferred embodiments of the present invention have been described above, and the features in these embodiments may be interchanged, substituted, or combined.
[0073] As can be seen from the above, in various embodiments of the decorative pencil sharpener of this utility model, the main parts that consumers can directly observe are all made of a stamped shell that can be printed with metallic colors (rather than thermoplastic materials that cannot be colored later or are difficult to print patterns on). On the one hand, this significantly improves the designer's freedom to create or beautify the outer wall of the stamped shell, that is, various colors and patterns can be printed on various parts of the outer wall with virtually no restrictions. When combined with the shape design of the stamped shell itself (such as, but not limited to, small animals, vehicles, or cartoon characters), the colors and patterns printed on the stamped shell can achieve a visual aesthetic that cannot be achieved in existing pencil sharpeners.
[0074] Furthermore, since the decorative pencil sharpener is assembled using a stamped shell with metal color printing, this does not substantially increase the process or material costs in the pencil sharpener manufacturing process. Considering the economies of scale brought about by large-scale stamping, the decorative pencil sharpener according to this utility model has considerable economic and commercial value.
[0075] It should be understood that although this specification describes various embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
