Because the third testing piece 203 has a certain height, the depth of the groove 111 can be set to be the same as the height of the third testing piece 203, so that the surface of the bottom plate 11 is aligned with the surface of the third testing piece 203, and the surface of the bottom plate 11 can be used as a plane where zero scales are located in the testing process.

In practical applications, the test process of the proximity sensor requires the use of a test specimen, a cover plate, and a test card. Wherein, the test sample is the proximity sensor to be tested. The cover plate may use a glass cover plate on the display screen of the mobile terminal, which is transparent to the test signal. The test card is used to simulate the face of a user to generate a reflected signal. The first test piece 201 may be a test card, the second test piece 202 may be a cover plate, and the third test piece 203 may be a test sample.

The test sample emits a test signal (e.g., infrared light) that passes through the cover plate to contact the test card and reflects off the test card to generate a reflected signal that passes through the cover plate and into the test sample. In this process, the tester acquires the height of the first sliding part 20 (i.e. the first distance), the height of the second sliding part 30 (i.e. the second distance), and the intensity of the reflected signal received by the test sample. And then, analyzing and processing the acquired data to obtain the performance data of the test sample.

In practical application, the test sample has a certain height. During the test, the height of the test sample can be obtained according to the specification of the test sample or through measurement. The first sliding portion 20 and the second sliding portion 30 can perform a reset operation at the height of the test sample, so that the distance measuring jig in the embodiment of the present application can adapt to the test samples with different heights, that is, to the test samples with different specifications.

The distance measurement tool in this application embodiment can adjust the position, the height of a plurality of test pieces respectively to can adapt to the test sample of different specifications, thereby can reduce the influence of the position, the height of test piece and the specification of test sample to test data, and then improve test data's accuracy.
