Description

Technical Field

[0001] This utility model relates to the field of office equipment technology, specifically to a folding paper cutter. Background Technology

[0002] Paper cutters, as common office and household tools, are widely used for cutting materials such as paper and photos. Currently, most paper cutter designs on the market typically employ a fixed, single-panel structure. While this traditional structure meets basic cutting needs, it has limitations in practical use. First, its portability is poor. The fixed, single-panel structure results in a relatively fixed overall size, occupying a large space and making it difficult to easily store in a bag or confined space, limiting its mobile use. Second, the cutting blades of traditional paper cutters are exposed or simply fixed externally. During movement, the blades are prone to accidental collisions, drops, or loosening or even detaching during transport, potentially causing cuts and damage to the blades themselves.

[0003] Therefore, there is an urgent need in the field for a paper cutter structure that can reduce the storage volume for easy carrying while providing effective protection for the cutter head.

[0004] Patent document CN101850559A discloses a paper cutter capable of switching paper cutting functions. The paper cutter includes a base plate, a cutting blade, a sliding blade assembly, a self-rotating base, and a rotating seat. The cutting blade and the sliding blade assembly are respectively fixed to the self-rotating base, the rotating seat is hinged to the base plate, and the self-rotating base is axially connected to the rotating seat. The paper cutter of this invention has cutting and trimming functions. By rotating the self-rotating base, the paper cutter changes the position of the corresponding cutting blade or sliding blade assembly and puts it into use. The sliding blade assembly or cutting blade that is not in use is hidden under the base plate. By rotating, the cutting blade or sliding blade assembly can be switched to select different paper cutting functions of the paper cutter. However, this paper cutter cannot be folded and stored, making it difficult to store in a bag or small space, and is not suitable for mobile use. Utility Model Content

[0041] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0042] This utility model discloses a folding paper cutter, which sets the traditional one-piece paper cutter into a foldable first panel assembly and a foldable second panel assembly, realizing a foldable design that is easy to store in a bag or small space, suitable for mobile use scenarios. In the folded state, the pressure plate and the cutter head can be accommodated in the receiving slot, avoiding the risk of the cutter head being accidentally bumped, dropped, or loosened or even falling off during movement.

[0043] According to the folding paper cutter provided by this utility model, such as Figures 1-4 As shown, it includes a first panel assembly 1 and a second panel assembly 2. One side of the first panel assembly 1 and one side of the second panel assembly 2 are foldably connected by a pivot assembly 3. Through the split foldable design, the paper cutting surfaces can be stored in opposite directions, making it convenient for moving and carrying. A pressure plate 23 is provided on the other side of the upper surface of the second panel assembly 2. The pressure plate 23 is provided with a through groove, and a cutter head 22 is slidably installed in the through groove. The upper surface of the first panel assembly 1 is provided with a pressure plate receiving groove corresponding to the pressure plate 23.

[0044] like Figure 1 As shown, in the open state: the upper surface of the first panel assembly 1 and the upper surface of the second panel assembly 2 are on the same plane; in a preferred embodiment, the pressure plate 23 is a transparent pressure plate and is set in the positioning grid area on the upper surface of the second panel assembly 2, which facilitates accurate observation of the paper cutting size.

[0045] like Figure 2As shown, in the folded state: the first panel assembly 1 and the second panel assembly 2 are folded relative to each other via a pivot assembly. The upper surfaces of the first panel assembly 1 and the second panel assembly 2 are positioned opposite each other. The pressure plate 23 is located in a pressure plate receiving groove on the upper surface of the first panel assembly 1. One end of the pressure plate receiving groove is provided with a blade receiving opening 12 corresponding to the blade head 22. In the folded state, the blade head 22 is embedded in the blade receiving opening 12. Through the design of the storage groove, both the blade head 22 and the pressure plate 23 can be stored inside, preventing the blade head 22 from becoming loose or even falling off due to accidental collisions, drops, or during carrying.

[0046] In a preferred embodiment, the bottom of the pressure plate receiving groove is provided with a tracing groove 11. The tracing groove 11 can have various shapes, such as wavy or zigzag, to facilitate the user to draw or trace lines on the paper.

[0047] In a preferred example, such as Figure 2 As shown, a card sleeve 12 is provided on the lower surface of the first panel assembly 1 for accommodating card-shaped objects.

[0048] In a preferred embodiment, the upper surface of the first panel assembly 1 is provided with a fixing groove 16; the fixing groove 16 is located outside the positioning grid area on the upper surface of the first panel assembly 1, and the upper surface of the second panel assembly 2 is provided with a fixing protrusion 27 corresponding to the fixing groove 16; in the folded state, the fixing protrusion 27 is inserted into the fixing groove 16 and is interference-fitted with the fixing groove 16. When the product is folded, the interference fit prevents the first panel assembly 1 and the second panel assembly 2 from easily opening. In more preferred embodiments, the fixing protrusion 27 includes a strip-shaped fixing protrusion, which is perpendicular to the sliding direction of the cutter head 22 and serves to guide the paper. After the paper is placed under the pressure plate 22, it is ensured to be perpendicular to the cutting direction of the cutter head 22 under the guidance of the strip-shaped fixing protrusion.

[0049] In a preferred example, such as Figure 4 As shown, the pivot assembly 3 includes a pivot body 31 and a pair of parallel pins 32. The pivot body 31 has two parallel pin holes, and the pair of parallel pins 32 are respectively inserted into the two pin holes. The ends of the pair of parallel pins 32 are respectively inserted into one side of the first panel assembly 1 and one side of the second panel assembly 2. The first panel assembly 1 and the second panel assembly 2 can rotate relative to the pivot body 31 via the parallel pins 32, thereby achieving a 180° fold. Further, there are multiple pivot assemblies 3, distributed along the length of one side of the first panel assembly 1.

[0050] In a preferred example, such as Figure 4As shown, the first panel assembly 1 includes a first base plate 15 and a first panel body 14 fixedly mounted on the first base plate 15; the second panel assembly 2 includes a second base plate 26 and a second panel body 25 fixedly mounted on the second base plate 26. Each of the two panel assemblies consists of two upper and lower plates combined together, optionally connected by hot-melt riveting. In more preferred embodiments, there is a cavity structure between the second base plate 26 and the second panel body 25; the second base plate 26 and the second panel body 25 are both provided with openings on one side perpendicular to the mounting side of the pivot assembly 3, forming a scratching knife receiving port 24 for inserting a scratching knife 21. The scratching knife 21 is inserted into the cavity structure through the scratching knife receiving port 24, and the scratching knife 21 can scratch along the concave lines in the positioning grid area on the upper surface of the panel assembly, and can be accommodated in the scratching knife receiving port 24 when not in use.
