Their design structure is reasonable, and they can accurately clamp building material specimens of different shapes and sizes, ensuring that the specimens are stable and do not slide during the compression test. The clamping part of the fixture is generally specially treated to increase friction and prevent the specimens from slipping under high pressure. Precise clamping can ensure that the specimens are in the correct position and stress state during the compression test, avoiding deviation of the test results caused by specimen sliding or offset. Stable clamping can prevent the specimens from suddenly breaking and splashing during the test, ensuring the safety of the testing personnel.

The outer side of the second spring 81 is fixedly connected with a baffle 82. The baffle 82 is slidably connected to the base 1. The outer side of the baffle 82 is clamped with the moving column 76.

[0027] As a technical optimization scheme of the present utility model, by setting the shielding mechanism 8, the debris generated during the detection can be shielded, avoiding the debris entering the inside of the base 1 and causing damage to the parts inside the base 1, and improving the use safety of the base 1.

[0028] Referring to FIG. 3, a friction pad 9 is fixedly connected to the inner side of the clamping plate 77. The friction pad 9 is located on the top of the base 1.
