Such a structural design can produce square or diamond-shaped standard samples to meet the sampling requirements. By sliding the second cutter 5, the third cutter 6, and the fourth cutter 7, standard samples of different sizes can be produced, such as (5*5) cm. 2 、(10*10)cm 2 wait.

[0024] A knife seat 8 is provided between each cutter and the mounting plate 3, and the cutter is fixed on the corresponding knife seat 8. The knife seat 8 corresponding to the first cutter 4 is fixed on the mounting plate 3, such as by bolts or welding. In fact, a dovetail block can be provided on the mounting plate 3, and a dovetail groove can be provided on the second cutter 5, the third cutter 6 and the fourth cutter 7. Then, the second cutter 5, the third cutter 6 and the fourth cutter 7 can be driven to slide respectively by the extension and contraction of three cylinders, so as to change the size of the cutting area. In this embodiment, a connecting plate 9 is provided between the knife seat 8 corresponding to the second cutter 5, the third cutter 6 and the fourth cutter 7 and the mounting plate 3. The connecting plate 9 and the knife seat 8 are integrally formed, so that the cross section of the knife seat 8 is L-shaped. Each cutter is detachably fixed on the vertical section of the L-shaped knife seat 8 by bolts.
