The two connecting shafts 103 are respectively arranged on the inner walls of the left and right side ends of the mounting frame 102. The two connecting shafts 103 are respectively connected to the inner rings of the corresponding bearings 116 and extend to the outside of the corresponding side ends of the mounting frame 102. The left and right side ends of the mounting frame 102 are provided with through holes 117 adapted to the corresponding connecting shafts 103.

[0025] like Figure 1 , 2As shown, the driving module includes a driving motor 201 which is laterally arranged at the left end of the mounting frame 102, a driving pulley 202 is arranged on the output shaft of the driving motor 201, a driven pulley which is adapted to the driving pulley 202 is arranged at the outer end of the left connecting shaft 103, and a transmission belt 203 is arranged between the driving pulley 202 and the driven pulley.

[0026] like Figure 3 As shown, a connecting plate 110 is provided at the top side end of the grinding plate 109, and a connecting bolt 111 for screwing and fixing with the mounting plate 108 is provided on the connecting plate 110, and a threaded connection hole adapted to the connecting bolt 111 is provided on the mounting plate 108. The connecting bolt 111 is a hand-tightened bolt. The user can conveniently adjust the connecting bolt 111 by hand.

[0027] After the user moves the pressure vessel to be polished between the pressing screw 105 and the connecting shaft 103 on the left, the pressing screw 105 can be turned and adjusted by the turning rod 106, so that the left and right side ends of the pressure vessel are respectively abutted and fixed by the connecting shaft 103 and the inner end of the pressing screw 105, thereby fixing the pressure vessel. Subsequently, the two connecting shafts 103 and the pressure vessel can be rotated by the driving module, and the polishing plate 109 can be gradually moved downward by the first telescopic push rod 107, so that the pressure vessel is polished by the polishing plate 109.
