As a standard qualified product, the correction sleeve 3 meets the strict standard requirements in terms of size and shape. During the measurement process, the correction sleeve 3 is not only used to calibrate the gauge, but also serves as a measurement reference to ensure the accuracy and consistency of the measurement results.

[0023] Specifically, the two support columns 4 not only have sufficient strength and rigidity to withstand various forces during the measurement process, but also have an upper end designed as an inclined surface to better meet the inclined installation requirements of the upper plate 5. The upper plate 5 is fixedly installed on the support columns 4 at an angle to form a stable measurement platform. The upper plate 5 adopts a rectangular structure design, which is not only easy to process and install, but also improves the stability and rigidity of the overall structure. The dial gauge 8 is installed on the upper plate 5 at an angle to ensure that the measurement personnel can clearly observe the value on the dial gauge 8.

[0024] Specifically, in order to accurately locate the detection end of the dial gauge 8 and reduce friction and error during the measurement process, the present embodiment adopts a positioning sleeve 6 of a "T"-shaped structure. The positioning sleeve 6 is installed on the upper plate 5 by screws, and an installation space is reserved inside the positioning sleeve 6 for installing the elastic bushing 7. The elastic bushing 7 is made of soft and durable material, which can tightly wrap the detection end of the dial gauge 8 and provide a certain buffering effect during the measurement process.
