The inner side of the protective cover 2 is fixedly connected to a mounting plate 203, and the mounting plate 203 is arranged on a side close to the door panel 201. The first cylinder 3 is fixedly installed on the top of the mounting plate 203, and the lower end of the piston rod of the first cylinder 3 slides through the mounting plate 203 and is fixedly connected to a fixed pressure plate 301. The second cylinder 6 is fixedly installed on the top of the supporting plate 402, and the lower end of the piston rod of the second cylinder 6 slides through the top of the supporting plate 402 and is fixedly connected to a movable pressure plate 601.

[0029] By adopting the above technical solution, when in use, the leather to be tested is first laid on the top of the testing platform 1, and then the piston rod of the first cylinder 3 is controlled to extend so that the fixed pressure plate 301 is pressed on one end of the leather, and then the piston rod of the second cylinder 6 is controlled to extend so that the lower end of the movable pressure plate 601 is pressed against the upper surface of the leather, and then the linear module 4 is started to drive the movable pressure plate 601 to move away from the fixed pressure plate 301, so that the leather between the movable pressure plate 601 and the fixed pressure plate 301 is flattened and tensioned, and at the same time, the laser thickness sensor 5 measures the thickness of the leather, wherein the distance between the laser thickness sensor 5 and the top of the testing platform 1 is known, set as A, and the distance measured by the laser thickness sensor 5 to the top of the leather is H, then the thickness of the leather is AH.

[0030] Specifically, the lower end of the movable pressing plate 601 is bent, and the angle between the lower end of the movable pressing plate 601 and the vertical direction is 45°-70°.
