[0055] Furthermore, for the square platform 602 , a positioning plate 15 is fixedly connected to the bottom of the square platform 602 .

[0056] There are multiple groups of positioning plates 15. The positioning plates 15 can limit and fix the position of the collection box 11 so that the filter barrel 12 in the collection box 11 can be aligned with the notch of the inclined plate 605 to prevent debris and coolant from falling outside the filter barrel 12.
