DETAILED DESCRIPTION

[0028] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0029] Reference Figure 1As shown, a magnetic fiber slicer 1000 of an embodiment of the utility model is shown, and the magnetic fiber slicer 1000 includes a first connecting plate 100, a second connecting plate 200, a first magnetic member, and a second magnetic member. The first connecting plate 100 is provided with a groove 110, and the second connecting plate 200 is provided with a tongue 210, and the tongue 210 is used to cooperate with the groove 110. The first magnetic member is connected to the first connecting plate 100, the second magnetic member is connected to the second connecting plate 200, and the second magnetic member is magnetically connected to the first magnetic member. The first connecting plate 100 and the second connecting plate 200 can be made of metal materials, the first magnetic member can be connected to the first connecting plate 100 by welding or pasting, and the second magnetic member can also be connected to the second connecting plate 200 by welding or pasting. The first magnetic member and the second magnetic member are magnets, and the polarities of the first magnetic member and the second magnetic member are opposite on the side where they are close to each other.

[0030] When in use, the fiber to be tested is first placed in the groove 110, and the tongue 210 is inserted into the groove 110 to squeeze the fiber to be tested. At the same time, the first magnetic component contacts the second magnetic component and is adsorbed together by magnetic force. The adsorption magnetic force of the first magnetic component and the second magnetic component can keep the first connecting plate 100 and the second connecting plate 200 tightly fitted together and not easy to loosen, thereby ensuring the slicing quality of the fiber to be tested.

[0031] Reference Figure 3 and Figure 5 As shown, according to some embodiments of the present invention, a first mounting groove 120 is provided on a side wall of the first connecting plate 100 close to the second connecting plate 200, and the first magnetic member is embedded in the first mounting groove 120. A second mounting groove 220 is provided on a side wall of the second connecting plate 200 close to the first connecting plate 100, and the second magnetic member is embedded in the second mounting groove 220. The first mounting groove 120 and the second mounting groove 220 can be provided to prevent the first magnetic member from protruding outside and affecting the cooperation between the first connecting plate 100 and the second connecting plate 200. The first mounting groove 120 and the second mounting groove 220 can be in a square, circular, triangular or other shape.

[0032] Reference Figure 3As shown, according to some embodiments of the utility model, the first connecting arm 230 and the second connecting arm 240 are respectively provided on both sides of the second connecting plate 200, the tongue 210 is located between the first connecting arm 230 and the second connecting arm 240, the first connecting arm 230 is provided with a first limiting groove 231, the second connecting arm 240 is provided with a second limiting groove 241, one side of the first connecting plate 100 cooperates with the first limiting groove 231, and one side of the second connecting plate 200 cooperates with the second limiting groove 241. By arranging the first connecting arm 230 and the second connecting arm 240 to cooperate with the first connecting plate 100, the first connecting plate 100 and the second connecting plate 200 can be prevented from loosening, and the two can be ensured to fit tightly. The first limiting groove 231 and the second limiting groove 241 can be square or arc-shaped.

[0033] Reference Figure 4 and Figure 5 As shown, according to some embodiments of the utility model, the first connecting plate 100 includes a plate body 130, a first protrusion portion 140 and a second protrusion portion 150, the first mounting groove 120 is provided at the first protrusion portion 140 or the second protrusion portion 150, the thickness of the first protrusion portion 140 and the second protrusion portion 150 are both greater than the thickness of the plate body 130, the groove 110 includes a first groove 111 and a second groove 112, the first groove 111 is provided at the plate body 130, and the second groove 112 is located between the first protrusion portion 140 and the second protrusion portion 150, the thickness of the second connecting plate 200 is greater than the thickness of the plate body 130, the tongue 210 includes a first tongue portion 211 and a second tongue portion 212, the thickness of the second tongue portion 212 is greater than the thickness of the first tongue portion 211, the first tongue portion 211 cooperates with the first groove 111, and the second tongue portion 212 cooperates with the second groove 112. Since there is a thickness difference between the plate body 130 and the first protrusion portion 140 and the second protrusion portion 150, when the fiber to be tested is placed in the first groove 111 of the groove 110, part of the fiber to be tested will be exposed outside the plate body 130, and the blade can cut the exposed part of the fiber to be tested along the surface of the plate body 130. The first protrusion portion 140 is inserted into the groove between the first connecting arm 230 and the tongue 210, and the second protrusion portion 150 is inserted into the groove between the second connecting arm 240 and the tongue 210, which plays a limiting role, and the contact area between the second tongue portion 212 and the second groove 112 is large, which can prevent the first connecting plate 100 and the second connecting plate 200 from loosening.

[0034] Reference Figure 3 and Figure 5As shown, according to some embodiments of the utility model, a plurality of first magnetic members and a plurality of second magnetic members are provided, and the plurality of first magnetic members are arranged one by one with the plurality of second magnetic members. The plurality of first magnetic members are divided into a first group, and the plurality of first magnetic members are divided into a second group. The first magnetic members of the first group are arranged on the first protrusion part 140, and the first magnetic members of the second group are arranged on the second protrusion part 150. The position distribution is more reasonable, which increases the contact area between the first magnetic member and the second magnetic member and enhances the adsorption force. The first magnetic member of the first group can be symmetrically arranged with the first magnetic member of the second group.

[0035] It is understandable that since the blade will contact the surface of the slicer, the surface of the slicer is easily worn, affecting the slicing quality of the fiber to be tested. At the same time, after slicing, acid-base testing or corrosion testing is sometimes required during the fiber observation process, and the entire slicer will be in an acid-base environment or a corrosive environment.

[0036] According to some embodiments of the utility model, the first connecting plate 100 and the second connecting plate 200 are made of stainless steel material to improve wear resistance and corrosion resistance. The surface of the first connecting plate 100 or the second connecting plate 200 is provided with a wear-resistant coating, and the wear-resistant coating is made of one of titanium nitride, titanium carbide, titanium aluminum nitride, titanium aluminum nitride, chromium aluminum nitride or diamond materials. For example, the Vickers hardness of titanium nitride is 1800 to 2100, it is insoluble in water, slightly soluble in aqua regia, nitric acid, and hydrofluoric acid, and has the characteristics of extremely high hardness, high thermal stability, wear resistance, low resistivity, and corrosion resistance. The melting point reaches 2950°C, and the friction coefficient of titanium nitride is 0.4, which can further improve the wear resistance and corrosion resistance of the slicer. The above-mentioned wear-resistant coating can be processed by ion spraying process, which is convenient to process.

[0037] According to some embodiments of the present invention, referring to Figure 6 and Figure 7 As shown, the tongue 210 and the second connecting plate 200 are connected through the reinforcing plate 250, and the width of the reinforcing plate 250 is greater than the width of the tongue 210. Specifically, the reinforcing plate 250 is connected to the second tongue portion 212, and the reinforcing plate 250, the tongue 210 and the second connecting plate 200 are an integral part. When the tongue 210 is inserted into the groove, the side surface of the reinforcing plate 250 abuts against the side surfaces of the first protruding block portion 140 and the second protruding block portion 150, which can prevent the first connecting plate 100 from flipping relative to the second connecting plate 200, and the connection is more stable, which plays a role in strengthening the structural strength and protecting the tongue 210.
