[0030] Example 1, please refer to the attached Figure 1 -Attached Figure 3 The base plate 1 is fixedly installed with a support seat, which plays a role of fixing and supporting when the motor 21 is driven, ensuring that the motor 21 can remain stable during operation.

[0032] Specifically, by setting up the sliding assembly 2, and utilizing the motor 21 to drive the first threaded rod 22 to drive the first slider 24 to move, the distance between the light source 8 and the optical receiving module 5 can be precisely adjusted to meet the testing requirements of optical fibers of different lengths.

[0034] Working principle:

[0035] First, place the optical fiber sample in the base 91, and adjust the height of the rotating block 93 by the third threaded rod 92, so that the optical microscope 10 can better observe and analyze the optical fiber at a suitable angle to obtain more detailed optical fiber information. The light source 8 provides the light required for the test, and the light is irradiated onto the optical fiber to be tested. The optical receiving module 5 receives the optical signal after transmission through the optical fiber, and the motor 21 is started to drive the first threaded rod 22 to rotate, so that the first slider 24 moves left and right along the first threaded rod 22, so that the support rod 3 drives the support plate 4 and the optical receiving module 5 installed on the support plate 4 to move through the first slider 24, so as to realize the precise adjustment of the horizontal position of the optical receiving module 5, and at the same time, the light blocking plate 7 is installed on the first bracket 6 to prevent the optical fiber from irradiating the optical receiving module 5 and interfering with the test results. At this point, the entire workflow ends.
