Then the staff places the graphite boat sheet on the top surface of the base plate, the pressing plate, the lifting plate, the connecting plate, and the stabilizing plate in turn. Then the staff pushes the graphite boat sheet forward so that one side of the graphite boat sheet contacts the chamfering blade. Then the telescopic rod of the air cylinder extends downward, driving the positioning plate and the positioning column to move downward. At this time, the pressing plate will first press on the graphite boat sheet on the base plate. Then the lifting plate moves downward synchronously, and the limiting hole slides downward on the surface of the fixed column, so that the lifting plate presses on the graphite boat sheet on the pressing plate. Then the connecting plate starts to move downward and presses on the graphite boat sheet on the top surface of the lifting plate. Then the stabilizing plate moves downward and presses on the graphite boat sheet on the top surface of the connecting plate.

[0014] II. When the pressing plate, the lifting plate, the connecting plate, the stabilizing plate, and the positioning plate press the graphite boat sheet downward, the elastic pad and the elastic material covering the surface of the pressing plate can protect the surface of the graphite boat sheet, increasing the safety during fixing of the graphite boat sheet. Before chamfering processing of the graphite boat sheet, the staff will first adjust the angle and height of the chamfering blade. First, the staff selects a distance for the nut, then pushes the sliding plate to slide in the sliding groove, determines the position, and then screws the nut back in, which determines the height of the chamfering blade. Then the staff adjusts the processing angle of the chamfering blade by unscrewing the adjusting bolt from the threaded groove by a certain distance, increasing the diversity of chamfering processing of the graphite boat sheet.
