The hacksaw frame consists of many triangular tooth tips. Because the point contact cutting effect is good, the tooth tip is back on both sides, which increases the strength, the tooth tip is not easy to be damaged, and sawing wood is labor-saving. The hacksaw saws steel bars into teeth by using the principle of woodworking saw, and is quenched to a certain hardness, tensile strength and elasticity, so it can saw iron and non-ferrous metals. The core of sawing objects lies in the tripod. The tip of the triangular rack is very sharp. When the sharp tooth tip moves on the surface of an object, the tooth tip will destroy the structure of the object and turn it into powder. This is the same as the process of crossing a paper with a needle.
