There are still certain defects in the existing scratch testing machines when in use.

[0003] In the prior art, the scratch testing machine is of great significance for evaluating the durability of products, the performance of surface protective layers, and quality control by simulating scratches. When the scratch testing machine is in use, the material is first fixed on the inner surface of the U-shaped sliding seat, and the bottom end of the scratching needle is placed on the surface of the material. At the same time, weights are placed on the connecting plate. When the scratch testing machine is started, the U-shaped sliding seat can move, so that the bottom end of the scratching needle can slide on the surface of the material. After the test, the scratches on the surface of the material can be observed to evaluate the scratch resistance of the material. During the use of the scratch testing machine, it is necessary to perform scratch tests on different positions of the material surface. During the process of performing scratch tests on different positions, the position of the material needs to be frequently moved and fixed. Usually, the position of the scratching needle is fixed, and the operator frequently moves and fixes the position of the material. This process is time-consuming, resulting in a low test efficiency of the scratch testing machine. Content of the Utility Model

[0014] 1. Scratch testing machines are widely used in the automotive industry, electronics industry, and coating industry. Scratch testing machines are mainly used to evaluate the scratch resistance of the surface of materials or coatings. During the use of scratch testing machines, it is difficult to adjust the position of the stylus body, which requires personnel to frequently adjust the position of the material, resulting in a low testing efficiency of the scratch testing machine. When the plug-in board moves, it can drive the rubber block to move. When the plug-in board is inserted into the two groups of card slots, the rubber block will be squeezed and deformed, thereby fixing the plug-in board between the moving block and the connecting block. When the lead screw rotates, it can drive the moving block to perform a threaded slide. When the moving block performs a threaded slide, it can drive the plug-in board to move. When the plug-in board moves, it can drive the connecting block to move. When the connecting block moves, it can drive the support seat and the connecting plate to move. When the guide rod moves, it can slide with the mounting plate. When the connecting plate moves to the specified position, the stylus body on the connecting plate can move to the specified position. At this time, scratch tests can be performed on other positions on the material surface. By rotating the lead screw, the position of the stylus body can be adjusted according to the actual situation, so that it is not necessary to frequently move and fix the material, which can save a lot of time and improve the testing efficiency of the scratch testing machine.

[0015] 2. During the use of the scratch testing machine, the material to be tested needs to be placed on the inner surface of the U-shaped sliding seat and fixed with a knob. This fixing method is likely to damage the material with a relatively soft surface, thus affecting the test results of the material. When the moving plate moves, it can slide through the connecting column. When the moving plate slides, it can compress the return spring. When the moving plate rises to an appropriate height, the material can be placed on the inner surface of the U-shaped sliding seat, so that the material to be tested is located below the rubber pad. When the moving plate is released, it can be reset by the elasticity of the return spring. When the moving plate is reset, it can drive the pressing plate and the rubber pad to squeeze and fix the surface of the material to be tested. Since the rubber pad is relatively soft and has a certain buffering property, when the rubber pad squeezes the surface of the material to be tested, it is not easy to damage the material with a relatively soft surface. The rubber pad can fix the relatively thin material and is not easy to damage the material, so that the test results are not easily affected. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 It can be seen that the present utility model provides a technical solution: a scratch testing machine that is conducive to adjusting the position of the stylus, including: an instrument main body 1, a touch screen 2, a fixed seat 3, a U-shaped sliding seat 4, a support seat 5, a connecting plate 6 and a stylus main body 7.

The shape of the plug-in board 13 is rectangular.

[0024] In specific implementation, the scratch tester is widely used in the automotive industry, electronics industry, and coating industry. The scratch tester is mainly used to evaluate the scratch resistance of the surface of materials or coatings. During the use of the scratch tester, it is difficult to adjust the position of the scratching needle body 7, which requires personnel to frequently adjust the position of the material, resulting in a low test efficiency of the scratch tester. The plug-in board 13 can be first pushed towards the two card slots 12. When the plug-in board 13 moves, it can drive the rubber block 14 to move. When the plug-in board 13 is inserted into the two card slots 12, the rubber block 14 will be squeezed and deformed, thereby fixing the plug-in board 13 between the moving block 10 and the connecting block 11. The moving block 10 and the connecting block 11 can be connected together through the plug-in board 13. After a certain position on the material surface is scratched by the scratching needle body 7, the lead screw 9 can be rotated. When the lead screw 9 rotates, it can drive the moving block 10 to perform a threaded slide. When the moving block 10 performs a threaded slide, it can drive the plug-in board 13 to move. When the plug-in board 13 moves, it can drive the connecting block 11 to move. When the connecting block 11 moves, it can drive the support base 5 and the connecting plate 6 to move. When the support base 5 moves, it can drive the guide rod 16 to move. When the guide rod 16 moves, it can slide with the mounting plate 15. When the connecting plate 6 moves to the specified position, the scratching needle body 7 on the connecting plate 6 can move to the specified position. At this time, the scratch test can be performed on other positions on the material surface.

[0025] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 It can be seen that by rotating the lead screw 9, the position of the scratching needle body 7 can be adjusted according to the actual situation, so that it is not necessary to frequently move and fix the material, which can save a lot of time and improve the test efficiency of the scratch tester.

[0026] Refer to Figure 1 and Figure 4 It can be seen that a through hole 17 is formed through the top of the U-shaped sliding seat 4. A connecting column 18 is connected inside the U-shaped sliding seat 4. A moving plate 19 is slidably connected to the outside of the connecting column 18. A return spring 20 is jointly connected between the moving plate 19 and the U-shaped sliding seat 4. A fixing column 21 is connected to the top of the moving plate 19 close to the through hole 17. An extrusion plate 22 is connected to the bottom of the moving plate 19. A rubber pad 23 is bonded to the bottom of the extrusion plate 22. The fixing column 21 and the U-shaped sliding seat 4 form a sliding structure through the through hole 17. The shape of the moving plate 19 is T-shaped.

[0027] During specific implementation, when the scratch testing machine is in use, the material to be tested needs to be placed on the inner surface of the U-shaped sliding seat 4 and fixed with a knob. This fixing method is likely to damage materials with a softer surface, thus affecting the test results of the materials. First, the moving plate 19 can be pulled towards the direction close to the through hole 17. When the moving plate 19 moves, it can slide through the connecting column 18. When the moving plate 19 slides, the return spring 20 can be compressed. And when the moving plate 19 moves, it can drive the fixing column 21 and the extrusion plate 22 to move. When the fixing column 21 moves, it can slide with the U-shaped sliding seat 4 through the through hole 17. When the moving plate 19 rises to an appropriate height, the material can be placed on the inner surface of the U-shaped sliding seat 4, making the material to be tested located below the rubber pad 23. At this time, the moving plate 19 can be released. When the moving plate 19 is released, it can be reset by the elasticity of the return spring 20. When the moving plate 19 is reset, it can drive the extrusion plate 22 and the rubber pad 23 to squeeze and fix the surface of the material to be tested. Since the rubber pad 23 is relatively soft and has a certain buffering property, when the rubber pad 23 squeezes the surface of the material to be tested, it is not easy to damage materials with a softer surface.

[0028] Referring to Figure 1 and Figure 4 it can be seen that the rubber pad 23 can fix thinner materials and is not easy to damage the materials, so that the test results are not easily affected.

[0029] To sum up, when using this scratch testing machine that is conducive to adjusting the position of the scratching needle, first, the plug-in board 13 can be pushed towards the direction of the two card slots 12. When the plug-in board 13 moves, it can drive the rubber block 14 to move. When the connecting plate 6 moves to the specified position, the scratching needle body 7 on the connecting plate 6 can move to the specified position. At this time, scratch tests can be carried out on other positions of the material surface. By rotating the lead screw 9, the position of the scratching needle body 7 can be adjusted according to the actual situation, so that it is not necessary to frequently move and fix the material, which can save a lot of time and improve the test efficiency of the scratch testing machine. Since the rubber pad 23 is relatively soft and has a certain buffering property, when the rubber pad 23 squeezes the surface of the material to be tested, it is not easy to damage materials with a softer surface. The rubber pad 23 can fix thinner materials and is not easy to damage the materials, so that the test results are not easily affected. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0030] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
