[0018] Further, the anti-slip protrusions are arranged at equal intervals on the top surface of the conical balance disk to form the anti-slip surface, and the anti-slip protrusions and the conical balance disk are of an integral structure.

[0028] During use, the height of the conical disc seat 11 and the conical balancing disc 12 is adjusted through the height adjustment bolt 15, so that the balancing device can adapt to the tested objects and test racks of different heights. During the test, adjusting the height according to the actual situation can ensure the position between the tested object and the tensile and compressive sensor test rack, improving the test accuracy. The contact area of the force application points can be increased through the surface of the conical balancing disc 12. When the tested object is placed on the anti-slip surface 13, the force can be made more uniform, reducing local stress concentration, which helps to protect the tested object and the test equipment, and at the same time improves the accuracy of the test results; by moving the conical balancing disc 12 on the conical disc seat 11, the fulcrum angle can be changed.

[0037] Further, in the above technical solution, the anti-slip protrusions 16 are block-shaped protrusions with a rectangular area at the bottom larger than that at the top.
[0038] Specifically, the principle of the present utility model is as follows: During use, the height of the conical disk seat 11 and the conical balance disk 12 is adjusted by the height adjustment bolt 15, so that the balancing device can adapt to measured objects and test stands of different heights. During the test, the height is adjusted according to the actual situation, which can ensure the position between the measured object and the tensile and compressive sensor test stand, improving the test accuracy.
