[0002] During bench calibration tests, performance tests, and product consistency tests on catalysts, different catalysts are frequently replaced for testing. When bench testing the catalyst, in order to ensure the connection between the catalyst and the bench exhaust pipe and the engine exhaust tail pipe, it is necessary to ensure that the catalyst has a certain installation height and installation stability. Previous designs often temporarily modified an exhaust pipe bracket for support, and cut and adjusted it according to the different installation heights of different catalysts, and required multiple people to cooperate in adjustment and fixation. The support had poor stability, was not firm, and position adjustment was inconvenient. This operation was time-consuming and labor-intensive, wasting bench resources, and was likely to cause injury to personnel during cutting and welding operations. The test preparation time was long, the test efficiency was low, and the labor intensity was high.
