[0039] The utility model relates to a quick-release detection mechanism and a test fixture. By setting a change-over base, the detection component is installed on the change-over base. The detection mechanism can be quickly disassembled and installed by only replacing the detection component. The quick-release detection mechanism is stable and reliable for long-term use and is easy to replace.

In addition, the quick-release mechanism has strong versatility and can be used on different test fixtures or equipment to facilitate the quick disassembly and assembly of the module structure. The utility model is based on the assembly of two sets of sunroof sunshade assemblies on a car in a new project. Considering the layout space and cost of the test fixture, we combine the two sunroof sunshade assemblies on a pair of test fixtures, share a set of references for clamping, and detect different sunroof sunshade assembly parts by quickly replacing different change-over blocks.
