[0025] Referring to Figure 1 and Figure 3The upper surface of the base 1 is fixedly connected with a mounting plate 16, and the upper surface of the mounting plate 16 is fixedly connected with a support 15, which is mainly used for supporting an electric push rod 19 and determining the mounting height and position of the electric push rod 19. The lower surface of the support 15 is fixedly connected with the electric push rod 19. The electric push rod 19 drives the pressing plate 20 to rise and fall through the telescopic movement of the output end, so that the pressure size can be adjusted according to different fabric thicknesses and test requirements, and it is ensured that the sample is firmly pressed on the mounting plate 16. The output end of the electric push rod 19 is fixedly connected with the pressing plate 20. The upper surface of the base 1 is fixedly connected with a fixed plate 3. The fixed plate 3 is rotatably connected with a bolt 9 inside. Before the sample is placed, the bolt 9 is rotated to separate the clamping plates 17, so that the sample is conveniently placed. After the sample is placed, the bolt 9 is reversely rotated to move the clamping plates 17 towards each other to preliminarily clamp the sample. The outer wall of the bolt 9 is threadedly connected with the clamping plate 17. The clamping plate 17 moves horizontally along the guide rod 18 under the drive of the bolt 9 to clamp the sample. The outer wall of the clamping plate 17 is slidably connected inside the mounting plate 16. The outer wall of the fixed plate 3 is fixedly connected with the guide rod 18. The guide rod 18 ensures the linearity and stability of the clamping plate 17 during movement, avoids uneven or unstable clamping of the sample due to the deviation of the clamping plate 17, and slidably connects the outer wall of the guide rod 18 with the inner side of the clamping plate 17.

[0026] Working principle: when using the device, the motor 4 is started, and the output end drives the eccentric wheel 6 to rotate. The rotary motion of the eccentric wheel 6 is transmitted to the moving rod 8 through the connecting rod 7, so that the moving rod 8 slides linearly in a specific direction inside the case 2. Since one end of the moving rod 8 is rotatably connected with the connecting plate 10, the friction plate 11 fixedly connected to the lower surface of the connecting plate 10 also moves reciprocally. The weight block 12 on the upper surface of the friction plate 11 can adjust the overall weight according to the test requirements, so as to change the pressure of the friction plate 11 on the sample below, so as to simulate the friction pressure in different actual scenes. The installation assembly at one end of the friction test paper is used to fix the friction test paper. The friction test paper is inserted into the installation cylinder 13, and then the fixed sleeve 14 is slid to tightly clamp the friction test paper. For the fixation of the sample, first, place it on the mounting plate 16, and rotate the bolt 9. Since the bolt 9 is threadedly connected with the clamping plate 17, and the clamping plate 17 can only slide linearly under the limitation of the guide rod 18, the rotation of the bolt 9 will make the clamping plate 17 move towards or away from each other inside the mounting plate 16, so as to preliminarily clamp and fix the sample. Then the electric push rod 19 is started, and the output end drives the pressing plate 20 to rise and fall. When the pressing plate 20 descends, the sample is pressed tightly, which further enhances the fixation effect of the sample, prevents the sample from loosening or shifting during the friction test, and ensures the accuracy of the test result.
