Along its length direction, the supporting shaft seats A5, supporting shaft seats B6 and supporting shaft seats C7 connected to the upper end of the frame by bolts are arranged at intervals in sequence. The supporting shaft seats A5, supporting shaft seats B6 and supporting shaft seats C7 divide the first rotating shaft 4 into a first hemming area and a second hemming area from right to left in sequence;

[0106] Two hemming plates 8, the cross section of the hemming plate 8 is in a "匚" shape. The two hemming plates 8 are respectively located in the first hemming area and the second hemming area, and the lower ends of the hemming plates 8 are fixedly installed on the outside of the first rotating shaft 4;
