A T-shaped slideway 7 is provided on the frame 1 below the support plate 23 in a fixed structure manner, and a T-shaped bolt 8 is provided in the T-shaped slideway 7. The head of the T-shaped bolt 8 cooperates with the T-shaped slideway 7 in a sliding structure manner. The T-shaped bolt 8 is provided with a nut through a threaded engagement manner, and the support plate 23 is connected to the T-shaped slideway 7 through the T-shaped bolt 8 and the nut.
