求翻译：包装箱尺寸走的下公差，而MC产品增加了护角，导致产品大、纸箱小的情况，因此纸箱套入困难，容易将包装箱撑破或将钢钉撑脱落。是什么意思？

Tolerance go by the size of the box, mc products to increase security angle, resulting in products, cartons, so cardboard boxes set into the difficult, easy to box bursting at the seams or to hold off the nail.

The Box size, and the tolerances MC products increased by the corner to the product, the small carton box, the box set, and therefore the difficulty, it's easy to stay in the box or the steel poles.

The packing case size walks under common difference, but the MC product increased has protected the angle, caused the product in a big way, the paper box small situation, therefore the paper box wrap entered the difficulty, broke open easily the packing case or falls off the steel nail brace.

Under the package of tolerance, and MC products increased the corner, resulting in products, carton small, so carton nest the difficult, easy boxes to break or steel nail support off.
