[0030] In this embodiment, by adjusting the distance between the two first limiting devices and the distance between the two second limiting devices, high applicability of clamping and limiting the molded products to be inspected with different sizes can be achieved.
[0031] Several sliding limit rods 19 are fixed to the test bracket 1, and several sliding docking plates 20 are fixed below the test limit plate 2. The test limit plate 2 is slidably mounted on the sliding limit rods 19 via the sliding docking plates 20.

[0034] In this embodiment, the test pressure plate 26 is screwed onto the docking rod 25 , and the test pressure plate 26 of different sizes and friction coefficients can be replaced according to different test requirements.
[0035] Working principle: Place the molded product to be tested on the test limit plate 2, and adjust the distance between the first limit plate 10 and the molded product through the second telescopic cylinder 6 so that the first limit plate 10 and the second limit plate 13 are located above the molded product. Then, under the action of the first telescopic cylinder 4, the first limit plate 10 and the second limit plate 13 are pressed onto the molded product.
[0036] The distance between the first limiting plate 10 and the second limiting plate 13 can be adjusted by the first limiting cylinder 8 and the second limiting cylinder 11, so that when the first limiting plate 10 and the second limiting plate 13 are pressed onto the molded product for limiting, they do not intersect with the third limiting plate 18 pressed onto the molded product.
[0037] The distance between the second limiting plate 13 and the molded product is adjusted by the fourth telescopic cylinder 17 so that the third limiting plate 18 is located above the molded product. Then, under the action of the third telescopic cylinder 15, the third limiting plate 18 is pressed onto the molded product.
[0038] Then, under the action of the pressure cylinder 24, the test pressure plate 26 is pressed onto the surface of the molded product, and the pressure sensor 27 senses the pressure on the molded product during the current wear test to adjust the wear test pressure. After the adjustment is completed, the adjustment cylinder 21 is started to drive the test limit plate 2 to move back and forth on the test bracket 1 for testing.
