After the vibration is absorbed by the buffer ring 13, the vibration will be absorbed by the rubber spring 202 and the vibration that is not completely absorbed will be transmitted to the limit plate 5, and the limit plate 5 will absorb and release the vibration that is not completely absorbed. After that, the vibration transmitted downward by the upper fixed plate 204 will be absorbed and released by the shock-absorbing pad 203, and the vibration that is not completely absorbed will be transmitted to the inner side of the support column 201 at the bottom of the lower fixed plate 4, and the support column 201 will absorb and transmit the vibration that is not completely absorbed to the shock-absorbing ring 15, and the shock-absorbing ring 15 will absorb and release the vibration that is not completely absorbed. Finally, after the motor test is completed, the user opens the clamping ring 205 and removes the rotating shaft of the motor from the inner side of the bearing 7.
