[0002] A hardness tester is a device used to measure the hardness of a material. It is widely used in hardness testing of materials such as metals, plastics, and glass. The working principle of a hardness tester is to calculate the hardness value of a material by applying a certain pressure to the material and observing the size and depth of the indentation based on hardness test methods such as Brinell hardness, Rockwell hardness, and Vickers hardness.

[0003] The existing hardness testing machine, during testing, first places the material on the testing table, applies pressure to the material through the testing head, then observes the size and depth of the indentation, and calculates the hardness value. When this method is used for hollow sheet metal parts, when pressure is applied, the sheet metal part as a whole will deform first, resulting in inaccurate testing results. For such sheet metal parts, the sheet metal parts can only be cut first, and the cut part of the sheet metal parts can be placed on the testing table for testing, but this method makes testing very inconvenient.
