[0002] As the public's requirements for various performances of automobiles are getting higher and higher, performance testing of automobiles after production has become particularly important. Automobile testing devices are needed to test the produced automobiles to ensure the safe use of the automobiles. During the test, the automobile body may move significantly, so the automobile body needs to be fixed. In the prior art, when the automobile body fixing device fixes the automobile body by fixing the wheels, the requirements for wheel fixing may be different depending on the test content. For example, when testing the driving force of the automobile, in order to better fix the automobile body and prevent displacement of the automobile body during the test, all four wheels need to be fixed.

[0003] However, some existing vehicle body fixtures for automobile testing can only fix wheels for models with a specific wheelbase. This limitation requires testers to frequently replace fixtures when testing multiple models, which not only increases the complexity and cost of the testing work, but also reduces the testing efficiency. Therefore, we propose a vehicle body fixture for automobile testing to solve the above problem. Utility Model Content
