求翻译下面一段成英文，谢谢
机器机身采用整体钢板焊接结构，具有良好的强度、刚度及抗振性。矩形下刀片，可使用四个刃口剪切，延长了刀片的使用寿命。还设有挡料机构，在限定的范围内可以调整剪切板料的宽度，在剪切大量的同一宽度的板料时，可大大的提高劳动的生产效率。
The machine body adopts whole steel welded structure, with good intensity, rigidity and vibration resistance. Rectangular blade, can use four blade shear, prolong the service life of the blade. Also provided with a feeding mechanism, can adjust the shear plate width in a limited range, in the plate shearing the same width when large quantities of, can greatly improve labor productivity.
