[0002] In the process of veneer material production, in order to evaluate the life and reliability of veneer materials, and also to predict the wear of veneer materials, it is usually necessary to perform wear resistance test on veneer materials. In order to facilitate the wear resistance test of veneer materials, staff usually use veneer material wear resistance test equipment. Existing veneer material wear resistance test equipment usually consists of a workbench, a driving mechanism, a fixing mechanism and a rubber grinding disc.

[0003] For example: The utility model with application number CN202321461890.7 discloses a wear resistance testing device, which specifically includes a platform, which is rotatably connected to a screw rod through a bearing, and the outer wall of the screw rod is threadedly connected to a curved rod, and two groups of pressure plates are fixedly connected to the curved rod, and the bottom ends of the two groups of pressure plates are fixedly connected to rubber pads. The screw rod is rotated by using a handle, and the screw rod can pull the curved rod to move downward on the outer walls of the two groups of sliding rods. When the curved rod moves downward, it can also drive the pressure plate to press down, and then the two ends of the textile placed on the platform can be fixed at the same time, which is convenient for disassembly and assembly, and then when multiple textiles are tested for wear resistance in turn, the installation speed can be accelerated and the overall test time can be reduced.

[0004] However, as far as the current traditional veneer material wear resistance testing device is concerned, during the wear resistance test of the veneer material, in order to ensure the test effect of the veneer material, the staff is usually required to flatten the veneer material first and then fix it, which is cumbersome to operate and inconvenient to use.
