The setting of the fixing rod 3 not only ensures the stability of the fixing plate 4 and makes the motor 5 run stably, but also avoids the situation of rotational dislocation of the lifting seat 7. A protective cover 8 is fixedly arranged inside the lifting seat 7. An observation component is arranged on the surface of the protective cover 8. The observation component includes a mounting sleeve 9 fixedly arranged on the surface of the protective cover 8. A transparent sleeve 11 is overlapped inside the mounting sleeve 9. A bolt 10 is overlapped inside the mounting sleeve 9. The threaded end of the bolt 10 passes through the mounting sleeve 9 and the transparent sleeve 11 and extends to the inside of the protective cover 8 and the inner wall of the protective cover 8. The setting of the transparent sleeve 11 not only protects the equipment and the operator, but also facilitates the operator to observe. The testing process of the disc spring is observed. A fixing frame 12 is fixedly arranged on the top of the test bench 1. A pressing assembly is arranged on the top of the fixing frame 12. The pressing assembly includes a hydraulic cylinder 13 fixedly arranged on the top of the fixing frame 12.
