The pressing part 40 is used to press the metal plate, and the telescopic part 30 is used to drive the supporting bar 50 and the shearing mechanism 10 to form a shearing force. After shearing, the telescopic part 30 retracts the supporting bar 50 into the supporting table 20, thereby exposing the edge of the metal plate. At the same time, the polishing part 70 is pulled to the position of the edge of the metal plate, and the polishing part 70 is driven by the translation part 60 to polish the whole cutting edge of the metal plate. In this way, the cutting is directly followed by polishing, thereby avoiding secondary clamping and improving the processing efficiency.

[0028] Please refer to Figures 1-4The pressing member 40 comprises a pressing plate 41 and a guide rod 42, the guide rod 42 is slidably connected with the knife holder 12, the pressing plate 41 is fixedly connected with the lower end of the guide rod 42, and the spring 43 is arranged on the pressing plate 41. During the downward movement of the knife holder 12, the pressing plate 41 first contacts the metal plate and presses it tightly, and then the cutter 14 continues to move downward to cut the metal plate along the edge of the supporting strip 50.

[0029] Please refer to Figures 1-4 The telescopic member 30 comprises a slide rod 31, and one slide rod 31 is fixedly connected with each end of the supporting strip 50 and slidably connected with the two sides of the supporting table 20.
