[0002] Nozzle pliers are a type of pliers used to cut the sprues of plastic products. Due to the low hardness of plastic products, the cutting edge angle of the sprue pliers is relatively small, thus achieving a sharp and labor-saving technical effect. The sprue of plastic products can be cut smoothly. The blade of the sprue pliers is relatively thin and sharp, and is suitable for cutting thin copper wires, plastics, rubbers and other materials. The incision after cutting the copper wire is flat, and the plastic is cut neatly. There are sprue pliers with long handles, short handles, and medium handles; there are sprue pliers made of different materials such as iron, copper, and aluminum.
