The components are all common standard parts or parts known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or through conventional experimental methods. The problem solved by the present invention is that it can only perform single-direction or limited-dimensional adjustment, making it difficult to comprehensively cover all parts of the freezer, with many detection blind spots. Traditional fixed-point temperature measurement or simple linear movement temperature measurement is difficult to capture the temperature change details at different positions of the freezer and cannot reflect the true temperature situation. Through the mutual combination of the above components, through the coordinated work of the longitudinal active control and adjustment structure 1, the longitudinal auxiliary adjustment mechanism 2, the transverse adjustment structure 3, and the lifting adjustment mechanism 4, precise adjustment of the infrared temperature measurement mechanism 5 in three-dimensional space is realized, enabling scanning temperature measurement around the surface of the freezer for comprehensive detection of the temperature at all positions of the freezer, avoiding detection blind spots, and greatly improving the comprehensiveness and accuracy of detection. Compared with traditional fixed-point temperature measurement or simple linear movement temperature measurement, circular trajectory movement can more evenly cover the surface of the freezer, capture the temperature change details at different positions of the freezer, especially for the situation where the surface temperature distribution of the freezer is uneven, and can more accurately reflect the true temperature situation, providing more reliable data support for the quality inspection of the freezer. It has a compact structure, occupies a small space, is convenient for installation and use in limited spaces such as freezer quality inspection workshops, and the connection methods between components are reasonably designed, ensuring both the overall stability of the device and facilitating subsequent disassembly and maintenance.
