[0022] like Figure 1 、 4As shown, a downwardly extending inclined surface 13 is provided at one end of the processing table 1 close to the upper cutting blade 6, and a linear module 12 fastened to the processing table 1 is symmetrically provided along the inclined surface 13. The top of the linear module 12 is connected to the support seat 3 through a sliding connection slider 4. The two support seats 3 are rotatably connected to the first rotating shaft 25. A limiting end plate 5 with an L-shaped cross-section is connected to the first rotating shaft 25. The supporting top surface of the limiting end plate 5 and the top of the lower cutting blade 26 are on the same plane, and a second motor 11 is fastened to one end of the first rotating shaft 25 to connect the linear module 12 and the second motor 1 1 is connected to the controller through a wire. According to the width of the plate to be processed, the linear module 12 is slidably controlled to adjust the distance between the limit end plate 5 and the lower cutting knife 26 to meet the shearing processing of plates of different sizes. The end of the plate is located on the top of the limit end plate 5 and abuts against it, which can also fix the plate and ensure normal shearing. After the shearing is completed, the second motor 11 is controlled to drive the limit end plate 5 to flip downward. The end of the plate is in contact with the top of the limit end plate 5 and falls to the top of the inclined surface 13, and the cut plate can be transported.
