[0030] Furthermore, by controlling the operation of the electric cylinder 23, the push plate 2 30 can be reciprocated, that is, the push wheel 2 31 pushes the push part 2 33 reciprocatingly, thereby causing the vibration slide 32 and the impact shaft 34 to reciprocate, and the impact shaft 34 reciprocates to impact the inner ring of the electric slip ring 7, so that it is subjected to force and then vibrates, so as to detect the working state of the electric slip ring 7 under vibration and external load.
