[0002] Trace water refers to extremely low levels of water in a sample, usually less than one thousandth, or even up to a few parts per million. The presence of trace water may have an important impact on many fields, such as petrochemicals, pharmaceuticals, and food science. There are many methods for measuring trace water, including the drying method, specific gravity method, and the more accurate Karl Fischer method. Among them, the Karl Fischer method is a commonly used method for determining trace water, which has the advantages of high sensitivity and high accuracy. This method determines the water content in a sample through a chemical reaction, which requires the use of specific reagents and instruments.

The above patent not only improves the convenience of liquid addition operation, facilitates the collection of waste liquid, reduces pollution, but also facilitates the acquisition and analysis of measurement results. However, in actual use, there are still the following deficiencies: from a practical point of view, the analyzer is not convenient to carry when used specifically, and personnel need to hold the analyzer to move it. There is a lack of protective devices during the movement process. If you are not careful, it is easy to cause the analyzer to fall, causing damage to the precision parts inside the analyzer, which will reduce the service life of the analyzer.

[0004] Therefore, a protective device for a trace water analyzer is needed to solve the problems in the prior art that the analyzer is inconvenient to carry and lacks a protective device, which reduces the service life of the analyzer. Utility Model Content

[0025] Through the elastic effect of the first spring 404, the analyzer body 1 placed between the pressure plates 406 can be fixed, and the position of the pressure plates 406 can be adjusted to clamp and fix analyzer bodies 1 of different specifications, thereby expanding the use range of the fixing mechanism 4.

[0026] Further Figure 1 , Figure 2 and Figure 3 As shown, it is worth to explain in detail that the pressing plate 406 is fixedly connected to the upper part of the rectangular block 405, and an anti-slip pad 407 is provided on one side of the pressing plate 406;

[0027] The anti-slip pad 407 may be made of rubber material to increase the friction between the pressing plate 406 and the analyzer body 1 and enhance the fixation in the analyzer body 1 .

[0028] According to the above working process, it can be known that: by setting the placement box 2, the placement box cover 3 and the fixing mechanism 4, the analyzer body 1 can be stably placed on the top of the placement plate 401 and fixed, which is convenient for carrying and moving the analyzer body 1, thereby improving the convenience of using the analyzer body 1. At the same time, the position of the analyzer body 1 can also be fixed to avoid displacement during movement and damage to it, thereby improving the safety of the device.

[0029] Further Figure 1 , Figure 2 and Figure 4 As shown, it is worth specifically explaining that the buffer mechanism 5 is composed of a mounting block 501, a connecting rod 502, a connecting block 503, a slider 504, a first hydraulic rod 505, a second spring 506, a fixed plate 507, a second hydraulic rod 508 and a third spring 509.
