An Improved Folding Knife

Abstract

The invention discloses an improved folding knife. The improved folding knife comprises a knife handle, a blade, an elastic arm and a limiting assembly. The knife handle is made of aluminum alloy. A containing groove is formed inside the knife handle, and a sliding groove is formed in one side of the knife handle. One end of the blade is hinged to one end of the knife handle, and the blade can be folded and unfolded relative to the knife handle. The containing groove is used for containing the blade when the blade is folded relative to the knife handle. The elastic arm is made of an elastic material. The elastic arm and the knife handle are of independent structures, and the elastic arm is located on one side of the containing groove. One end of the elastic arm is a fixed end, the other end of the elastic arm is an abutting end, and the fixed end is fixedly arranged on the knife handle. The elastic arm is used for providing elastic force enabling the abutting end to move towards the containing groove. The limiting assembly comprises a stop piece and a positioning mechanism. The knife handle of the improved folding knife is high in strength and light, and the blade can be effectively prevented from being folded by accident.

Description

technical field [0001] The present invention relates to an improved folding knife. Background technique [0002] A folding knife generally includes a handle, a blade and an elastic arm. The blade can be expanded and folded relative to the handle. The elastic arm is used to abut against the end of the blade when the blade is unfolded, so as to prevent the blade from automatically folding. In the existing folding knives, the spring arm is generally integrally formed with the handle. In this way, both the handle and the spring arm need to be made of elastic materials, which not only makes the strength of the handle not high, but also cannot be made of lighter materials. . Furthermore, since the elastic arm is made of elastic material, when the blade is suddenly subjected to external force or shakes suddenly, the elastic arm is easily squeezed away by the blade, which causes the blade to fold unexpectedly, thereby causing the user to be cut.

Problems solved by technology

In the existing folding knives, the spring arm is generally integrally formed with the knife handle. In this way, both the knife handle and the spring arm need to be made of elastic materials, which not only makes the strength of the knife handle not high, but also cannot be made of lighter materials.

Furthermore, since the elastic arm is made of elastic material, when the blade is suddenly subjected to external force or shakes suddenly, the elastic arm is easily squeezed away by the blade, which causes the blade to fold unexpectedly, thereby causing the user to be cut.
