Abstract

The utility model discloses a spring knife which comprises a knife blade and a knife handle. The knife blade is riveted with the knife handle through the action of rivets; the knife handle is formed by two plate bars which are connected through pins; a space for containing the knife blades is left between the two plate bars; the riveting end of the knife blades is provided with a cam ring; a spring plate which is abutted against the cam ring is arranged at the inner side of the plate bars of the knife handle and formed by that a steel plate which is attached at the inner side of the plate bars is partially hollowed and integrally molded. The utility model has the advantages of few used parts, simple structure of the parts, simple assembly, reduction of processing operation and reduction of labor cost.

Description

A kind of flick-knife

Technical field

The utility model relates to a kind of five metals cutter, more particularly, relates in particular to a kind of flick-knife.

Background technology

The present flick-knife of selling on the market, as long as press unlock switch, blade can eject, its convenience is liked by the user deeply, but its weak point also is clearly, complex structure, assembling difficulty, the manufacturing procedure more complicated, labour cost is than higher, and the volume of its finished product is general, and also the volume than common pocket knife is big, is difficult for developing to miniaturization.

Summary of the invention

The purpose of this utility model is in order to remedy the deficiencies in the prior art, a kind of novel structure, advantages of simple to be provided, safe and practical flick-knife.

The utility model is achieved through the following technical solutions.

The utility model is a kind of flick-knife, include blade and handle of a knife, blade is riveting in handle of a knife by the rivet activity, handle of a knife is connected to form by pin by two plates, leave the space that holds blade between two plates, the riveted end of described blade is provided with cam ring, and handle of a knife plate inboard is provided with the shell fragment inconsistent with cam ring, and this shell fragment is hollowed out through part by the steel disc that is mounted on the plate inboard and is made of one piece.

Above-mentioned cam ring and blade riveted are on same rivet, and cam ring and blade are installed for fixing the applying:

The free end of above-mentioned shell fragment is near cam ring, and in the cam ring rotation process, the ledge of the free end of shell fragment energy and cam ring is inconsistent.

The beneficial effects of the utility model are that the parts of use are few, and the structure of parts is also simple, assemble up fairly simplely, have reduced manufacturing procedure, have reduced labour cost.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.

As shown in Figure 1 and Figure 2, the utility model is a kind of flick-knife, include blade and handle of a knife, blade is riveting in handle of a knife by the rivet activity, and handle of a knife is connected to form by pin by two plates, leaves the space that holds blade between two plates, the riveted end of described blade is provided with cam ring 1, cam ring 1 and blade riveted are on same rivet, and cam ring 1 installs for fixing the applying with blade, its objective is in order to make the synchronized movement of blade and cam ring 1.Be provided with the shell fragment 2 inconsistent with cam ring 1 in handle of a knife plate inboard, this shell fragment 2 is hollowed out through part by the steel disc 3 that is mounted on the plate inboard and is made of one piece.In particular, the free end of shell fragment 2 is near cam ring 1, and in cam ring 1 rotation process, the ledge of the free end of shell fragment 2 energy and cam ring 1 is inconsistent.Cam ring 1 and shell fragment 2 are complementary, and be indispensable.

Operation principle of the present utility model is as follows: in the blade rotation process, cam ring 1 is synchronized with the movement, in the process of handle of a knife of turning back, the ledge of cam ring 1 will be conflicted with the free end of shell fragment 2, amount to back conflict still in the handle of a knife fully up to blade, in just individual process, cam ring 1 extrusion elastic 2 makes it have elastic potential energy; When opening blade, press unlock switch, blade was ejected in elastic acting force following moment of shell fragment 2, reached the purpose of opening automatically.
