Description

Folding knife with elastic rod body

This creation is about folding knives, especially a type of folding knives that use the elastic rod body as the power source to push the blade body.

Press, the folding knives currently sold in the market are composed of a handle and a knife body, wherein the knife body and the knife handle are pivotally connected to each other, so that the knife body can rotate along its pivot position, and is rotated to the Outside the handle, or be rotated and stored in the handle, and because the folding knife is small in size after being folded, it is convenient for people to carry around, and the body of the knife is stored in the handle, which is also safer to carry. , Therefore, for users such as divers, outdoor activities, military police, etc., the folding knife has a high degree of convenience compared to other knives that cannot be stored.

Generally speaking, most of the current folding knives use Volute Springs as the power source to push the knife body. The volute spring is installed at the pivot between the knife body and the knife handle, and its two ends abut against each other. The knife body and the knife handle can always generate a force to push the knife body outward. Therefore, as long as the user opens the mechanism of locking the knife body, the knife body will be automatically moved toward the knife body by the force of the scroll spring. Out, so that when the user encounters a special or emergency situation and only has one hand left, the switchblade can be used quickly to deal with critical situations, such as when a fisherman is diving, and When one hand is entangled in the fishing net, the switchblade knife can be used to cut the fishing net immediately, so as to escape the danger smoothly and avoid serious threat to his life.

However, conventional folding knives using scroll springs have the following problems: (1) In order to facilitate the user to carry and store the folding knife, the volume of the folding knife is usually designed to be small, and the volume of the scroll spring is also reduced. It is rolled into a scroll shape, so the aforementioned smaller volume scroll spring will cause difficulties in production; (2) During the assembly process, due to the small volume of the scroll spring, it is not easy to accurately fix the scroll spring to the pivot between the cutter body and the handle, which not only prolongs the production time, but also leads to product failure. The non-performing rate increased; (3) In order to install the scroll spring in the handle, the thickness of the handle must be increased to insert the scroll spring. This situation obviously conflicts with the design concept of reducing the volume of the folding knife. It will undoubtedly increase the difficulty of design, and the thicker handle is not conducive to the user's grip, especially for users with small palms; (4) Since both ends of the scroll spring need to abut against the cutter body and the cutter handle respectively, in order to generate the force that pushes the cutter body outward, the existing method is to open a groove on the pivot on the cutter handle , so that one end of the scroll spring can be hooked in the groove of the pivot, and the other end of the scroll spring can be hooked on the knife body. That said, it is even more difficult to successfully complete the assembly procedure of the hook.
