When the bonding surface of the specimen is deformed and damaged or the bonding surfaces of the two specimens are not parallel, the feedback data on the sensing plate 901 will have a large deviation, indicating that the bonding surface of the specimen does not meet the test specifications and the specimen needs to be replaced). If the test results meet the standards, the gluing, bonding and stretching tests will be carried out. Otherwise, the specimen will be replaced.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
