[0002] Microhardness tester is a precision instrument for testing the performance of metal materials in the machinery, metallurgy and other industries. It is widely used in various industries. In special fields, hardness, especially Vickers hardness and Koch hardness, are used as substitute characteristics to replace other material characteristics. They are often used to measure the hardness of each phase in the material or the extremely thin layer on the metal surface (such as electroplating layer, nitriding layer), etc. Its value can be expressed by Mohs hardness HM, Vickers hardness HV or Knoop hardness HK. When measuring, the sample must be ground and polished to a bright plane, and eroded to expose the microstructure, and then tested and observed under the microhardness tester.

[0022] Sliding openings 16 are provided on the inner walls of both sides of the placement groove 14, and sliding seats 17 are slidably connected in the two sliding openings 16. Threaded holes 18 are provided on the two sliding seats 17, and threaded rods 19 are threadedly connected in the two threaded holes 18. One end of the two threaded rods 19 is rotatably connected to the two side walls of the placement block 15 respectively. A limiting opening 20 is provided on the inner wall of one side of the two sliding openings 16, and limiting blocks 21 are slidably connected in the two limiting openings 20. The two limiting blocks 21 are fixedly connected to the two sliding seats 17 respectively, so that the lateral and longitudinal displacement adjustment work can be conveniently completed, so that the position of the sample can be adjusted according to the needs, which greatly meets the use needs of the staff. A control component is provided on the fixed cylinder 3, and the control component includes a control component arranged on the fixed cylinder 3. A rotating opening 10 is provided on one side wall of the fixed cylinder 3, and a rotating column 11 is rotatably connected in the rotating opening 10. A support frame 22 is fixedly connected to the upper end surface of the base 1, and the rotating column 11 penetrates the support frame 22.

During the rotation process, the rotating column 11 can drive the threaded tube 4 to rotate by means of the meshing of the first bevel gear 12 and the second bevel gear 13. Since the threaded column 5 in the threaded tube 4 is fixedly connected to the support table 6, and the support table 6 cannot rotate by means of the setting of the limiting groove 7 and the limiting rod 8, the threaded column 5 can be driven to rise and fall while the threaded tube 4 rotates, and then the sample on the placement table 9 can be raised and lowered to a suitable height, and then the staff can cooperate to complete the detection work, which is greatly beneficial to the use of the staff and the work can be done at the same time. Personnel can also rotate the two threaded rods 19. Since the sliding seat 17 cannot rotate due to the limitation of the sliding opening 16, the placement block 15 can be pulled to slide in the placement groove 14 while the threaded rod 19 is located in the threaded hole 18 and rotates. The sliding of the sliding seat 17 in the sliding opening 16 ensures that the sliding work of the placement block 15 will not be interfered with. The setting of the limit opening 20 and the limit block 21 ensures that the placement block 15 can remain fixed after sliding. In this way, the two threaded rods 19 can cooperate to complete the lateral and longitudinal displacement adjustment of the placement table 9, so that the sample can be moved relative to the microscope component 2, and then cooperate with the staff to better complete the detection work, which greatly meets the different needs of the staff.
