[0028] The auxiliary table 3 is detachably mounted on the workbench 21 . A positioning groove 3a is provided on one side of the auxiliary table 3 close to the second mounting portion 12 . The positioning groove 3a is used to place the workpiece to be tested. The detection port of the detection member 4 faces the positioning groove 3a.

[0029] A specific embodiment, such as Figure 1As shown, the lower end of the mounting seat 1 is provided with the first mounting portion 11, and the upper end is provided with the second mounting portion 12. The auxiliary table 3 is placed on the first mounting portion 11. In the present application, multiple auxiliary tables 3 can be provided, and different auxiliary tables 3 have positioning grooves 3a with different positions and sizes. During detection, auxiliary tables of different specifications can be replaced according to the size of the workpiece to be detected and the detection position. When detection is required, the workpiece to be detected is placed in the positioning groove 3a of the auxiliary table 3, and the lifting mechanism 2 is operated to drive the workbench 21 to move upward and close to the detection member 4 of the second mounting portion 12. Since the detection port of the detection member 4 is facing the positioning groove 3a, the detection member 4 can detect the hardness of a specific area of ​​the workpiece to be detected; after the detection is completed, the lifting mechanism 2 is operated to drive the workbench 21 to move downward, and the auxiliary table 3 and / or the workpiece to be detected can be replaced at this time.
