In summary, the upper blade 905 and the lower blade 1003 can be easily replaced.

[0045] The shearing mechanism of the shearing machine drives the rotating shaft to rotate by a driving motor so as to drive the upper shearing plate assembly and the lower shearing plate assembly to move synchronously towards each other, so as to perform upper and lower synchronous shearing of the inserted plates to improve the shearing effect of the plates. At the same time, the upper mounting bolts on the side of the movable plate of the upper shearing plate assembly and the lower mounting bolts on the side below the sliding plate of the lower shearing plate assembly are used to facilitate the disassembly and replacement of the upper blade and the lower blade, which is simple to operate and easy to use.
