[0021] See also Figure 1-4 , the utility model provides a technical solution for a high hardness test probe:

[0022] Example 1:

[0023] like Figure 1-3 As shown, a high hardness test probe includes a probe body 1 and a bracket 2. The bracket 2 is arranged on the outside of the probe body 1. One end of the probe body 1 is sleeved with a first limiting ring 3. Two positioning plates 4 are arranged at the bottom of the first limiting ring 3. Concave holes 5 are provided on both sides of the two positioning plates 4. One end of the bracket 2 is sleeved with a second limiting ring 6. The bottom surface of the second limiting ring 6 is provided with an auxiliary groove 7. Two auxiliary strips 8 are provided inside the auxiliary groove 7. One end of the two auxiliary strips 8 is provided with an L-shaped plate 9. One side of the two L-shaped plates 9 is provided with a restraining plate 11. Both sides of the two restraining plates 11 are provided with limiting strips 13. One end of the two limiting strips 13 is embedded in the corresponding concave holes 5, and the two are threadedly connected, so that the first limiting ring 3 and the second limiting ring 6 can be limited and fixed, further ensuring the firmness of the installation of the probe body 1. The material of the outer surface of the probe body 1 is tungsten, which has high hardness and extends the service life of the probe body 1.

[0024] Example 2:

[0025] Based on the first embodiment, Figure 1 and Figure 4As shown, the two auxiliary strips 8 are respectively movable inside the auxiliary groove 7, and a retaining ring 12 is fixedly sleeved on one end of the two auxiliary strips 8. A roller 10 is rotatably installed on one side of the two L-shaped plates 9, and one side of the two restraining plates 11 is respectively fixedly connected to one side of the two rollers 10. The utility model provides a high-hardness test probe. By setting a bracket 2, an internal thread 14, an external thread 15 and a retaining ring 12, the bracket 2 is embedded in one end of the probe body 1, and the threaded connection between the internal thread 14 and the external thread 15 is utilized to install the probe body 1 and ensure its stability. The retaining ring 12 is fixed on one end of the auxiliary strip 8, thereby enhancing the smoothness of the movement of the auxiliary strip 8.

[0026] Working principle: Test probes are usually used to measure the hardness of materials. Their design includes a sturdy tip and a precise measuring mechanism to ensure accurate testing on different materials. Common test methods include Brinell, Rockwell and Vickers hardness tests. Through the test probe, the wear resistance and strength of different materials during processing and use can be evaluated. The probe is usually connected to the bracket 2 through a thread. The bracket 2 is part of the test equipment. The test probe is used to detect subsequent materials through the test equipment. After the probe body 1 and the bracket 2 are threaded, since the two are connected by a single thread, frequent installation and disassembly will cause thread wear. The probe body 1 will gradually loosen with the bracket 2. Loosening will cause the probe position to be unstable, affecting the measurement accuracy and increasing the cost of repairing the probe body 1. For this reason, it is particularly important to design a high hardness test probe. The bracket 2 is embedded in one end of the probe body 1, and the internal thread 14 and the external thread 15 are connected. The threaded connection allows the probe body 1 and the bracket 2 to be installed to ensure their stability. The retaining ring 12 is fixed to one end of the auxiliary strip 8, which enhances the smoothness of the movement of the auxiliary strip 8. In order to enhance the firmness of the installation of the probe body 1 and the bracket 2, the two auxiliary strips 8 can make circular motions inside the auxiliary groove 7. Therefore, the auxiliary strip 8 can be rotated according to the position of the positioning plate 4 so that the restraining plate 11 is located directly above the positioning plate 4. By rotating the roller 10, the restraining plate 11 fixed thereto can be driven to rotate. After the inner surface of the restraining plate 11 contacts the outer surface of the positioning plate 4, one end of the two limiting strips 13 is then embedded in the corresponding concave hole 5. The two are threadedly connected, so that the first limiting ring 3 and the second limiting ring 6 can be limited and fixed, further ensuring the firmness of the installation of the probe body 1. The material of the outer surface of the probe body 1 is tungsten, which has high hardness and extends the service life of the probe body 1.
