A testing device is also fixedly connected to the top of the maintenance workbench, and a first storage slot is located at the top of the workbench. However, this patent does not allow for adjustment of the angle of the maintenance workbench during testing, resulting in high labor intensity for workshop operators. Furthermore, positioning and supporting the chemical instruments is cumbersome and involves a large amount of work, leading to reduced calibration efficiency. Therefore, this utility model provides a calibration device for daily maintenance of chemical instruments. Utility Model Content

[0026] See Figure 1 — Figure 4 The top two ends of the support block 12 and the bottom of the adjustment frame 20 are movably connected by a hinge rod 13 through a hinge 16. The calibration base 10 has a movable groove 17 at the top of the support cavity 14. The hinge rod 13 moves through the movable groove 17. The angle of the adjustment frame 20 can be adjusted by rotating the two ends of the hinge rod 13.
[0027] Limiting rods 18 are fixedly installed on both sides of the supporting screw 15 in the support cavity 14 by bolts. The two ends of the supporting block 12 are movably inserted through the limiting rods 18.

The angle of the adjusting frame 20 is adjusted by the first turntable 19.
[0028] See Figure 1 — Figure 4 The positioning assembly also includes a rotating rod 23 that moves within the adjusting frame 20. The rotating rod 23 is movably connected to the center of the adjusting frame 20 via a bearing. Both ends of the rotating rod 23 are provided with positive and negative threads 24. The positioning blocks 21 are threaded through the positive and negative threads 24 on the rotating rod 23. The top ends of the positioning blocks 21 are fixedly installed with positioning rods 25 by bolts.
