Abstract

Disclosed is an elastic piece support folding knife. The elastic piece support folding knife comprises a blade and a knife handle plate, wherein the blade is hinged onto the knife handle plate through a pin shaft, the knife handle plate is fixed into a blade casket through a fixing pillar, the blade can be folded and contained in the blade casket and can also be unfolded from the blade casket, an elastic piece is arranged on the inner side of the knife handle plate, a flat bottom portion is arranged at the tail end of the blade, and a first bulge and a second bulge are arranged on the upper side and the lower side of the tail of the blade. According to the elastic piece support folding knife, the elastic piece is arranged on the inner side of the knife handle plate of the elastic piece support folding knife, the flat bottom portion is arranged at the tail end of the blade, the first bulge and the second bulge are arranged on the upper side and the lower side of the tail of the blade, and therefore the second bulge is limited by the fixing pillar when the blade is unfolded from the blade casket, and simultaneously the elastic piece is popped out and pressed against the flat bottom portion, and then the blade is under balance stress from all directions, and thereby the knife is firm and furthermore is safe to use. The elastic piece support folding knife is stable in support, simple in structure, and convenient to install and operate.

Description

[0001] technical field [0002] The invention relates to a knife, in particular to a folding knife capable of folding a blade into a knife handle. [0003] Background technique [0004] Most of the existing folding knives are composed of a blade and a handle with a certain cavity. The blade is movably connected to the handle through a hinge shaft. The knife handle is expanded outwards, and some folding knives are equipped with a switch device, and the blade is folded and unfolded by toggling the switch device. Because the blade of the existing folding knife is mainly supported by the elastic switch device, the force that the blade can bear in each direction is different, and the blade is easy to fold back when the force is too large. [0005] Existing folding knives, such as the Chinese invention patent application whose patent application number is 201110437211.8, discloses a folding knife, which includes: a blade with a locking switch mounting hole at the top; a handle w...
