Products are updated and iterated quickly, so the implementation work is more frequent. Each product requires multiple tests, and sometimes multiple products need to be tested at the same time. The current common method is to test each test item separately, so the experimental site and experimental equipment require a large investment. The more experiments are conducted, the more times the product needs to be manually transferred and clamped, resulting in large site requirements, more personnel, lower efficiency, and risk of product damage. Because it is difficult to ensure consistency during each clamping, there is a risk that the test results may be affected.

[0004] In order to solve the above problems, this application proposes a vehicle armrest stiffness fatigue testing device. Summary of the invention
