[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0038] like Figures 1-8 As shown, this utility model provides a cutting device, including a placement platform 1 and a cutting tool 2. The placement platform 1 is used to place the workpiece 4 to be cut. The cutting tool 2 includes a tool body 21 and a plurality of cutting parts 22. The tool body 21 is provided with a plurality of mounting slots 211 spaced apart along a first direction. Each cutting part 22 is detachably installed in any mounting slot 211 and at least partially protrudes from the mounting slot 211. At most one cutting part 22 is installed in a single mounting slot 211. The plurality of cutting parts 22 can all abut against the workpiece 4 to be cut and divide the workpiece 4 to be cut into a plurality of cutting units.

[0039] In this embodiment, the tool body 21 is provided with multiple mounting slots 211 spaced apart along the first direction. Each cutting component 22 is detachably installed in any mounting slot 211, allowing the user to flexibly adjust the position of each cutting component 22 and the number of cutting components 22 installed in the cutting tool 2 as needed. This controls the number and size of the split units cut by the multiple cutting components 22, meeting the user's diverse needs for split units, improving the flexibility of cutting and the versatility of the cutting device. At most one cutting component 22 is installed in a single mounting slot 211 to ensure that each cutting component 22 works independently, preventing collisions caused by at least two cutting components 22 being installed in the same slot, ensuring the cutting quality of the cutting device for the cutting component 4. When a certain cutting component 22 is worn, it can be directly disassembled and replaced without adjusting other cutting components 22, making the disassembly and assembly process simple and the maintenance efficiency higher. The placement platform 1 is used to place the workpiece 4 to be cut. The placement platform 1 provides a flat working reference surface for the cutting process of the cutting tool 2, effectively overcoming the cutting deviation caused by the unevenness of the traditional cutting plane. Setting up the placement platform 1 ensures a smooth cutting process, improving the cutting quality and accuracy of the workpiece 4. The cutting tool 2 includes multiple cutting components 22. These components, installed within the tool body 21, can abut against the workpiece 4. Pulling the tool body 21 in any direction forming an angle with the first direction allows the multiple cutting components 22 to divide the workpiece 4 into multiple cutting units, significantly improving cutting efficiency compared to manual cutting. In this embodiment, the first direction is the width direction of the workpiece 4, which will not be described further.

[0040] Specifically, such as Figures 4-6 As shown, the tool body 21 includes a handle portion 212 and a mounting portion 213 fixedly connected. The cross-sectional area of ​​the handle portion 212 is smaller than the cross-sectional area of ​​the mounting portion 213. A plurality of mounting slots 211 are spaced apart on the mounting portion 213 along a first direction. Compared to a tool body 21 where the cross-sectional areas of the handle portion 212 and the mounting portion 213 are the same, the cutting device proposed in this embodiment can reduce the fatigue of the user when gripping for a long time and improve the user's hand operation.

[0041] More specifically, the handle 212 includes a guide surface 2121 and a transition surface 2122 arranged at an angle. One side of the transition surface 2122 is connected to the guide surface 2121, and the other side is connected to the mounting part 213. The guide surface 2121 and the transition surface 2122 are connected to form a handle notch. Compared to a right-angled notch, the handle notch formed by the angled guide surface 2121 and the transition surface 2122 is more compatible with the natural grip curve of the user's palm, improving grip stability.

[0042] Optionally, the spacing between two adjacent mounting slots 211 is consistent and ranges from 1.8mm to 2.2mm. When each mounting slot 211 is equipped with a cutting element 22, pulling the tool body 21 can divide the workpiece 4 to be cut into multiple cutting units with a width between 1.8mm and 2.2mm. For example, when the spacing between two adjacent mounting slots 211 is 2mm and there are 5 mounting slots 211 between two adjacent cutting elements 22, pulling the tool body 21 can divide the workpiece 4 to be cut into multiple cutting units with a width of 10mm. In other embodiments, the user can install multiple cutting elements 22 in mounting slots 211 at different positions according to usage requirements to cut cutting units of other widths. The cutting device proposed in this embodiment has high cutting flexibility and can meet the diverse size requirements of the cutting units for the user.

[0043] Specifically, the portion of the cutting element 22 protruding from the mounting groove 211 has a beveled surface, the tip of which can abut against the part to be cut 4. Compared to a rectangular surface abutting against the part to be cut 4, this improves the cutting accuracy of the cutting element 22 and reduces the difficulty of inserting the cutting element 22 into the first guide groove 31. For example, the cutting element 22 can be a utility knife in the prior art, with multiple preset dividing lines spaced along its length. When the cutting effect of the cutting element 22 decreases after multiple cuts, the user can break off the worn portion of the cutting element 22 along the preset dividing lines and continue cutting.

[0044] In this embodiment, the cutting device further includes a limiting member 3, which, together with the placement platform 1, can press the workpiece 4 to be cut. Figures 1-3 As shown, the limiting member 3 is positioned above the workpiece 4 to be cut, and the placement platform 1 is positioned below the workpiece 4 to be cut. The limiting member 3 and the placement platform 1 can press the workpiece 4 to be cut firmly, suppressing the positional displacement of the workpiece 4 due to force when the user pulls the tool body 21. Setting the limiting member 3 can enhance the positioning effect of the workpiece 4 to be cut during the cutting process. The limiting member 3 and the placement platform 1 can be interlocked or connected by fasteners to enhance the connection effect of the limiting member 3 and the placement platform 1 and improve the pressing effect of the limiting member 3 and the placement platform 1 on the workpiece 4 to be cut.

[0045] Specifically, both the placement platform 1 and the workpiece 4 to be cut are rectangular. The limiting member 3 can be a rectangular frame, with its width direction consistent with the width direction of the placement platform 1. The limiting member 3 can press against the edge of the workpiece 4 to restrict its displacement during the cutting process. In other embodiments, the limiting member 3 can also be a rectangular plate, increasing the contact area between the limiting member 3 and the workpiece 4 to improve its limiting effect. To avoid the limiting member 3 obstructing the cutting operation, such as... Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, the limiting member 3 is provided with a plurality of first guide grooves 31 at intervals along the first direction. The cutting member 22 can be inserted into the first guide groove 31 and abut against the member 4 to be cut. At most one cutting member 22 can be inserted into a single first guide groove 31. The first guide groove 31 provides a cutting channel for the cutting member 22 so that the cutting process can proceed smoothly, and also provides clear guidance for the cutting trajectory of the cutting member 22, thereby improving the cutting accuracy.

[0046] Optionally, the first guide groove 31 can be a rectangular groove, extending along the length direction of the limiting member 3. When the tool body 21 is pulled, the multiple cutting members 22 can divide the workpiece 4 to be cut into multiple rectangular cutting units. For example, the workpiece 4 to be cut is filter paper. When the tool body 21 is pulled in a direction at an angle to the first direction, the multiple cutting members 22 can cut the filter paper into filter paper strips. The user can pull the tool body 21 in a second direction perpendicular to the first direction to achieve optimal labor-saving operation. The second direction is the length direction of the workpiece 4 to be cut, and will not be described in detail hereafter.

[0047] Preferably, the dimensions of the multiple first guide grooves 31 are consistent, and the dimensions of the multiple cutting pieces 22 are also consistent. The width of the first guide groove 31 is consistent with the thickness of the cutting piece 22, so as to avoid the cutting piece 22 from shaking within the first guide groove 31 during the cutting process, which would reduce the cutting accuracy. It can also improve the consistency of the multiple cutting units after being cut by multiple cutting pieces 22, thereby improving the cutting quality. It can be understood that the thickness direction of the cutting piece 22 is consistent with the width direction of the first guide groove 31 and the width direction of the mounting groove 211.

[0048] Multiple second guide grooves can also be provided at intervals along the first direction on the placement platform 1. The second guide grooves are connected to the first guide grooves 31 one by one. When the tool body 21 is pulled along a direction that forms an angle with the first direction, the cutting piece 22 can enter the second guide groove through the first guide groove 31 and the piece to be cut 4 in sequence. This ensures that the cutting piece 22 can achieve the cutting penetration effect of the piece to be cut 4 with a single pull of the tool body 21, avoiding repeated cutting operations and improving cutting efficiency.

[0049] Optionally, the cutting device further includes a first measuring unit, which is disposed along a first direction on the side of the limiting member 3 away from the placement platform 1. The first measuring unit is configured to measure the total width of multiple cutting units. The first measuring unit allows the user to intuitively and quickly obtain the cumulative width data of the multiple cutting units that have already been cut, accurately determine whether the target cutting amount has been reached, and prevent the user from continuing to cut the remaining parts 4 after obtaining the required width of the cut units. This limits the over-processing of the parts 4 and allows the remaining parts 4 to be flexibly applied to subsequent cutting operations with different width requirements, improving the overall utilization rate of the parts 4 and reducing material waste.

[0050] The cutting device may further include a second measuring unit, which is disposed along a second direction on the side of the limiting member 3 away from the placement platform 1. The second direction is perpendicular to the first direction. The second measuring unit is configured to measure the length of the cutting unit. The second measuring unit allows the user to visually determine the length of the cutting unit and accurately judge whether the target cutting length has been reached. This prevents the user from continuing to cut the remaining parts 4 after obtaining the required length of the cut unit, limiting over-processing of the parts 4 and allowing the remaining parts 4 to be flexibly used for subsequent cutting operations with different length requirements.

[0051] Optionally, the first measuring part can be a measuring tool capable of measuring the total width of multiple cutting units, such as a tape measure or vernier caliper, or it can be multiple scale lines marked with corresponding data set on the upper surface of the limiting member 3 along the first direction. The second measuring part can be a measuring tool capable of measuring the length of the cutting unit, such as a tape measure or vernier caliper, or it can be multiple scale lines marked with corresponding data set on the upper surface of the limiting member 3 along the second direction.

[0052] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
