The driving shaft of the driving device 31 passes through the first bracket 33 and is connected with a pulley. One end of the mounting shaft 32 protruding from the first bracket 33 is also connected with a pulley. The pulleys at both places are connected by a belt 35 to realize the driving device 31 driving the mounting shaft 32 to rotate.
