The rotating column 26 drives the rocker arm body 27 to swing. The rocker arm body 27 drives the aerospace cable body 29 to perform bending tests on the first pulley 20 and the second pulley 21. At the same time, the counterweight 15 slides on the limiting slide rail 16. The aerospace cable body 29 is counterweighted to increase the accuracy of the test.
