The distance between the front end plate 2 and the circulating motor 5 is determined first, and then the front end of the circulating motor 5 is located inside the rear end plate 3, and then the upper plate 31 and the lower plate 32 are fixed on the limiting plate through bolts respectively. And according to different models of the circulating motor 5, the upper plate 31 and the lower plate 32 with different radius through holes 6 can be selected.
