[0002] Filter paper is a porous paper-based filter medium made of fibrous materials such as cotton fibers or wood pulp. It can separate solids from liquids or liquids from each other through physical barriers. To fit container sizes and facilitate single-use or handling of the filter paper, it usually needs to be cut.

[0003] However, most existing filter papers rely on manual cutting tools, which has the following drawbacks: First, the number of filter papers obtained in a single cut is small, resulting in low cutting efficiency; second, manual cutting cannot guarantee that the size of the filter paper after each cut is controllable, resulting in poor cutting quality.

[0004] Therefore, there is an urgent need to develop a cutting tool to solve the problems of low cutting efficiency and poor cutting quality in the traditional cutting process. Utility Model Content

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] like Figures 1-2 As shown, this embodiment provides a cutting tool, including a handle 1, a mounting assembly 2, and multiple cutting components 3. The mounting assembly 2 includes a mounting frame 21 and a mounting shaft 22. The mounting frame 21 is fixedly connected to the handle 1, and the mounting shaft 22 is detachably disposed on the side of the mounting frame 21 away from the handle 1. The multiple cutting components 3 are spaced apart along the axial direction of the mounting shaft 22 and can all abut against the workpiece to be cut. The multiple cutting components 3 are configured to divide the workpiece to be cut into multiple cutting units when the handle 1 is pushed in a first direction at an angle to the axial direction of the mounting shaft 22.

[0033] In this embodiment, multiple cutting elements 3 are spaced apart along the axial direction of the mounting shaft 22 and can all abut against the workpiece to be cut. After the multiple cutting elements 3 abut against the workpiece, when the handle 1 is pushed along a first direction at an angle to the axial direction of the mounting shaft 22, the spaced-apart cutting elements 3 can divide the workpiece into multiple cutting units. That is, by pushing the handle 1 along the first direction, multiple cutting units can be obtained simultaneously with the help of multiple cutting elements 3, improving cutting efficiency. Furthermore, the multiple cutting units are cut by the pre-assembled multiple cutting elements 3, and the shape and size of the multiple cutting units obtained are controllable, improving cutting quality. In addition, the mounting shaft 22 is detachably set on the side of the mounting frame 21 away from the handle 1 to facilitate the installation of multiple cutting elements 3 during initial assembly. Compared with the movable connection between the mounting frame 21 and the handle 1, the fixed connection between the two improves the operational reliability and safety of the cutting tool and reduces the risk of the mounting frame 21 falling off when the user applies force to the handle 1.

[0034] In one embodiment, multiple cutting elements 3 are fixedly connected to the mounting shaft 22 to improve the structural integrity of the multiple cutting elements 3 and the mounting shaft 22. Specifically, multiple retaining rings can be fixedly provided on the mounting shaft 22, with the multiple retaining rings spaced apart. The number of retaining rings is the same as the number of cutting elements 3. The cutting elements 3 are sleeved on the outside of the mounting shaft 22 and fixedly connected to the retaining rings one by one. The cutting elements 3 can be disc-shaped, semi-disc-shaped, or have beveled surfaces. It is understood that when a semi-disc-shaped or beveled cutting element is installed on the mounting shaft 22, the arc apex of the semi-disc or the tip of the beveled surface can abut against the workpiece to be cut, thereby improving the cutting accuracy.

[0035] In other embodiments, multiple cutting pieces 3 can also be coaxially rotatably mounted on the mounting shaft 22 to reduce the operator's workload and achieve a labor-saving effect. Specifically, multiple bearings can be rotatably mounted along the axial direction of the mounting shaft 22, with the bearings spaced apart. The number of cutting pieces 3 is the same as the number of bearings, and they are connected one-to-one. When the handle 1 is pushed in the first direction, the multiple cutting pieces 3 can rotate synchronously around the mounting shaft 22 to cut the workpiece to be cut. Preferably, the cutting pieces 3 are disc-shaped to reduce the contact area between the cutting pieces 3 and the workpiece to be cut, reduce frictional resistance, and improve cutting efficiency. It is understood that the multiple cutting pieces 3 in this embodiment are of the same size to maintain synchronous rotation. For example, the thickness of each cutting piece 3 can be between 0.15mm and 0.3mm to improve the cutting accuracy of the workpiece to be cut.

[0036] Specifically, the spacing between two adjacent cutting pieces 3 is consistent. By pushing the handle 1 along the first direction, multiple cutting pieces 3 can be used to obtain multiple cutting units of the same size. Compared with the traditional manual cutting method, the cutting tool proposed in this embodiment can not only maintain the consistency of the cutting units and improve the cutting accuracy, but also obtain multiple cutting units at the same time through a single cutting, thereby improving the cutting efficiency.

[0037] For example, when the material to be cut is filter paper, the distance between two adjacent cutting pieces 3 can be between 2.3mm and 2.6mm, so that the cut slitting units can be used in the DNA extraction process. The first direction can be a direction perpendicular to the axial direction of the mounting shaft 22. In this case, the plane where the filter paper is located is parallel to the first direction. When the handle 1 is pushed along the first direction, multiple cutting pieces 3 can cut the filter paper into multiple filter paper strips of the same width. The cutting tool can be equipped with forty cutting pieces 3 to produce multiple filter paper strips in one pushing process, significantly improving cutting efficiency. In other embodiments, the first direction can also be any continuously changing direction that forms an angle with the mounting shaft 22, so that slitting units with serrated edges, slitting units with smooth arc edges, or irregularly shaped slitting units can be obtained along the first direction, to adapt to the usage requirements of slitting units in different application scenarios.

[0038] In this embodiment, the ratio of the distance between the contact point of the multiple cutting pieces 3 and the piece to be cut and the mounting shaft 22 and the distance between the end of the handle 1 away from the mounting bracket 21 and the mounting shaft 22 is between 1:10 and 1:5. This not only ensures that the position of the user operating the handle 1 is kept at a certain distance from the multiple cutting pieces 3, improving the safety of operation, but also saves effort.

[0039] Specifically, the mounting bracket 21 has a first mounting groove 211 and a second mounting groove 212, and both ends of the mounting shaft 22 are respectively inserted into the first mounting groove 211 and the second mounting groove 212. The insertion and engagement of the mounting shaft 22 with the mounting bracket 21 facilitates the installation and removal of the mounting shaft 22, and also facilitates the inspection and maintenance of the multiple cutting parts 3 mounted on the mounting shaft 22. In this embodiment, the openings of the first mounting groove 211 and the second mounting groove 212 are aligned and have the same width.

[0040] Furthermore, a first elastic pad is provided in the first mounting groove 211, and a second elastic pad is provided in the second mounting groove 212. One end of the mounting shaft 22 passes through the first mounting groove 211 and abuts against the first elastic pad, while the other end of the mounting shaft 22 passes through the second mounting groove 212 and abuts against the second elastic pad. The first and second elastic pads enhance the connection strength between the mounting shaft 22 and the mounting bracket 21, and also reduce the rigid impact on the mounting assembly 2 and handle 1 when multiple cutting parts 3 are cutting the parts to be cut, thus extending the service life of the cutting tool. For example, both the first and second elastic pads can be made of rubber material.

[0041] Optionally, the handle 1 is cylindrical to accommodate the curvature of the user's hand, facilitating the application of force. Preferably, the side of the handle 1 away from the mounting bracket 21 is provided with an anti-slip pad or machined with anti-slip threads to reduce the risk of the handle 1 accidentally slipping from the user's hand during cutting, thus improving the user's operational stability. To enhance the ease of operation of the cutting tool, the handle 1 can be made of plastic and have an internal hollow structure to reduce the overall weight of the cutting tool.

[0042] For example, the cutting tool also includes a protective cover, which at least partially covers the plurality of cutting pieces 3 and is detachably connected to the mounting bracket 21. The protective cover prevents accidental cuts to the user by the multiple cutting pieces 3, ensuring the user's safety. In this embodiment, the mounting bracket 21 is inverted U-shaped, with the mounting shaft 22 installed within the U-shaped opening. The multiple cutting pieces 3 are fitted onto the mounting shaft 22 and at least partially located outside the opening of the mounting bracket 21. The protective cover is U-shaped and covers the portion of the multiple cutting pieces 3 located outside the opening of the mounting bracket 21, and is detachably connected to the mounting bracket 21. The protective cover and the mounting bracket 21 can be connected by a snap-fit ​​or a threaded connection. Furthermore, when the cutting tool is not in use, it can be completely stored in a protective housing. The protective housing improves the dustproof and moisture-proof effect of the cutting tool, extending its service life.

[0043] 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.
