The rotating shaft 401 drives the cam 402 and the indicator rod 407 to rotate at the same time. The staff can judge the angle of the cam 402 by the angle of the indicator rod 407, so as to observe the squeezing of the pressing plate 9, so as to keep the fiber bundle tight and improve the sewage filtration effect.
