[0029] The side surface of fixed mold 1 is fixed with fixed block 6, the side surface of fixed block 6 is provided with distance adjusting screw 7, and hinge rod 4 is fixedly connected with distance adjusting screw 7.

[0030] The adjustable lead screw 7 that passes through the fixed block 6 can adjust its extension length according to the thickness of the metal plate being processed, so as to avoid the inability to process due to the small gap between the fixed mold 1 and the moving mold 2.
