[0024] The limiting protrusion 23 is embedded in the limiting groove 24, and the limiting protrusion 23 and the limiting groove 24 cooperate with each other. The outside of the gear 7 is processed with a tooth block, and the side of the rack 8 close to the gear 7 is processed with a tooth block of the same size as the outside of the gear 7;

[0025] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the leather to be tested is placed on the top of the support plate 5. After placing it, the servo motor 17 is started. The servo motor 17 drives the gear 7 to rotate through the connecting shaft 18. Since the gear 7 and the rack 8 cooperate with each other, and the rack 8 is fixedly connected to the top of the limit plate 22, the rotation of the gear 7 can make the rack 8 drive the limit plate 22 to descend. When the limit plate 22 descends, the leather can be pressed against the inside of the limit groove 24 through the limit protrusion 23, so that the leather can be positioned to prevent the leather from accidentally moving during the inspection and affecting the accuracy of the inspection.

[0026] Embodiment 2: A limiting slide groove 12 is provided on one side of the protective shell 6 close to the base 1, a limiting slider 13 is fixedly connected to one side of the rack 8 close to the base 1, the limiting slider 13 slides up and down inside the limiting slide groove 12, a limiting rod 19 is fixedly connected to the rear end of the mounting plate 11, a limiting groove 21 is provided on the rear end of the supporting frame 9, and the rear end of the limiting rod 19 slides up and down inside the limiting groove 21;

[0027] Specifically, Figure 1 and Figure 3 As shown, when the rack 8 is raised or lowered, the limit slider 13 will slide up and down inside the limit slot 12, so that the rack 8 can be limited by the limit slot 12 to prevent the tooth block outside the gear 7 and the tooth block on one side of the rack 8 from being misaligned. The hydraulic cylinder 10 drives the tube-type thrust gauge 20 to descend through the mounting plate 11. When the tube-type thrust gauge 20 descends to a certain height, it can be placed on the leather to test the hardness of the leather. When the mounting plate 11 is raised or lowered, the limit rod 19 and the limit slot 21 can limit the mounting plate 11 and the tube-type thrust gauge 20.

[0028] Embodiment 3: A frame 3 is provided at the middle position of the top of the base 1, a storage box 2 is provided inside the frame 3, movable casters 14 are installed at the four corners of the bottom of the storage box 2, both sides of the bottom of the frame 3 are fixedly connected to a limit frame 15, a handle 16 is fixedly connected to the front end of the storage box 2, a protective cover is provided outside the handle 16, the movable caster 14 is provided inside the limit frame 15, and the limit frame 15 limits the movable caster 14;

[0029] Specifically, Figure 1As shown, after the inspection is completed, the leather is unfixed and then falls into the storage box 2, so that the inspected leather can be collected. When another group of leather is inspected, the handle 16 is pulled, and the handle 16 drives the storage box 2 out of the frame 3, so that it is convenient to take out the inspected leather when processing another group of leather, which can improve the inspection efficiency.

[0030] Working principle: When the utility model is in use, the leather to be tested is placed on the top of the support plate 5. After placing it, the servo motor 17 is started. The servo motor 17 drives the gear 7 to rotate through the connecting shaft 18. The rotation of the gear 7 can make the rack 8 drive the limit plate 22 to descend. The limit plate 22 can press the leather against the inside of the limit groove 24 through the limit protrusion 23 when it descends, so that the leather can be positioned. When the rack 8 is raised or lowered, the limit slider 13 will slide up and down inside the limit slide groove 12, so that the rack 8 can be limited by the limit slide groove 12 to prevent the tooth block outside the gear 7 and the tooth block on one side of the rack 8 from being misaligned. After the leather is fixed, the hydraulic cylinder 10 is started. The hydraulic cylinder 10 drives the tube-type thrust gauge 20 to descend through the mounting plate 11. The tube-type thrust gauge 20 When it is lowered to a certain height, it can be placed against the leather to test the hardness of the leather. When the mounting plate 11 is raised or lowered, the limit rod 19 and the limit groove 21 can limit the mounting plate 11 and the tube-type thrust gauge 20, thereby improving the stability of the lifting and lowering of the tube-type thrust gauge 20. After the detection is completed, the servo motor 17 is started again, and the servo motor 17 drives the gear 7 to reverse through the connecting shaft 18, so that the rack 8 can drive the limit plate 22 to rise and make the leather lose its fixation. After the leather loses its fixation, it will fall into the storage box 2, so that the leather that has been tested can be collected, and when another group of leather is tested, the handle 16 is pulled, and the handle 16 drives the storage box 2 to separate from the inside of the frame 3, so that it is convenient to take out the tested leather when processing another group of leather, which can improve the detection efficiency.
