Abstract
The utility model discloses a folding knife which belongs to manual cutters. The knife heads of the existing folding knives have the disadvantages that the machining cost is high, material is wasted, and the assembly precision of a blade and the head is reduced and the blade swings due to the factors of machining and assembly errors and the like. The main body of the knife head with a filling structure is formed in a way that a metal plate is bent to form a shell and a hard filler is filled in the shell, and the shell comprises two side walls connected by the ridge part and a space formed between the two side walls and used for filling the hard filler. The knife head with the filling structure is convenient to produce, the material is saved, and a die can be utilized to implement the procedures of bending the metal plate to form the shell and filling the hard filler into the shell, so that the production precision of the main body of the knife head is ensured, and the assembled blade is prevented from swinging. Furthermore, for the knife head with the structure, a locking structure for locking the blade can be directly made on the shell, thereby being convenient to produce, simple in structure and convenient to operate.
