[0018] Among them, in combination with Figure 1 As shown, the base 1 is stepped. The base 1 includes a first disc 11 and a second disc 12 arranged on the first disc 11. The diameter of the first disc 11 is larger than that of the second disc 12. The first disc 11 and the second disc 12 are integrally formed. The cylinder 5 is arranged on the second disc 12.

[0019] Specifically, the outer dimensions of the lower caliper plate 2 are enlarged proportionally by 0.5 - 1 mm according to the outer dimensions of the standard skate brick. In this embodiment, the outer dimensions of the lower caliper plate 2 are made by enlarging proportionally by 1 mm according to the outer dimensions of the standard skate brick, and the thickness of the lower caliper plate 2 is one-tenth of the thickness of the standard skate brick. The outer dimensions of the upper caliper plate 4 are reduced proportionally by 0.8 - 1 mm according to the outer dimensions of the standard skate brick.

[0020] It should be noted that for the present application, the outer dimensions of the lower caliper plate 2 are made by enlarging proportionally by 1 mm according to the outer dimensions of the standard skate brick, that is, the outer contour of the orthographic projection of the standard skate brick on the lower caliper plate 2 is the first standard contour, the outer contour of the lower caliper plate 2 is the lower contour, and the distance between the lower contour and the standard contour is 1 mm. The outer dimensions of the upper caliper plate 4 are made by reducing proportionally by 1 mm according to the outer dimensions of the standard skate brick, that is, the outer contour of the orthographic projection of the upper caliper plate 4 on the standard skate brick is the upper contour, the outer contour of the standard skate brick is the second standard contour, the outer dimensions of the first standard contour and the second standard contour are equal, and the distance between the upper contour and the second standard contour is 1 mm.

The lower caliper plate 2 is used to detect whether the skateboard brick meets the maximum appearance size. Then, the skateboard brick 3 to be detected is sleeved on the cylinder 5 and its lower end is in contact with the lower caliper plate 2, and the length and width directions of the skateboard brick 3 to be detected and the lower caliper plate 2 are made consistent. Then, the upper caliper plate 4 is sleeved on the cylinder 5, the upper caliper plate 4 is in contact with the skateboard brick 3 to be detected, and the length and width directions of the upper caliper plate 4 and the lower caliper plate 2 are made consistent. The upper caliper plate 4 is used to detect whether the skateboard brick meets the minimum appearance size. Thus, it can be quickly and intuitively obtained whether the skateboard brick 3 to be detected is between the maximum size and the minimum size, so as to quickly detect whether the skateboard brick 3 to be detected is qualified. The detection speed is fast and the detection efficiency is high. If the minimum size of the skateboard to be detected does not need to be detected, the upper caliper plate 4 can not be installed.
