Abstract

A novel spring knife comprises a knife hilt and a knife blade which is connected onto the knife hilt and can be folded into the same. The knife blade is equipped with a convex column capable of popping out the knife blade, the convex column is fixedly arranged on the knife blade and is pressed with a spring piece arranged on the knife hilt, the spring piece and the knife hilt are integrally connected formed via one-step stamping, the knife blade is equipped with a shifting part used for controlling popping out of the knife blade, the knife hilt is equipped with a lock part used for locking theknife blade, and the lock part is ejected on the bottom portion of the knife blade to lock the same when the knife blade is unfolded so as to prevent the stressed knife blade from backwardly foldingwhen used by a user. The novel spring knife utilizes one-step stamping forming of the spring piece and the knife hilt, leads the spring piece and the knife hilt to be connected integrally, simplifiescomponent structures, reduces processing procedures, is extremely easy in assembling, simple in structure and skillful in design, saves resources, reduces manufacturing cost, and is highly praised andappreciated by consumers.

Description

A kind of novel spring pocket knife

Technical field

The utility model relates to five metals cutter manufacturing technology field, is a kind of novel spring pocket knife specifically.

Background technology

At present, flick-knife of the prior art all is to adopt the whole piece spring to install on the handle of a knife of pocket knife, utilizing an end of spring to prop up the top blade outwards ejects, it is easy to use, very popular, but its weak point is the flick-knife consumptive material of the type structure, the assembling more complicated, and adopt and manually cause manufacturing cost too high in a large number, so the utility model just should this generation.

The utility model content

The purpose of this utility model is the shortcoming that overcomes above-mentioned prior art, provides a kind of simple in structure, convenient and practical, can reduce manufacturing cost and proper a kind of novel spring pocket knife attractive in appearance.

The utility model is to be achieved through the following technical solutions:

A kind of novel spring pocket knife comprises handle of a knife and is connected on the handle of a knife and can be equivalent in blade in the handle of a knife that described blade is provided with the projection that blade outwards can be ejected, and this projection fixedly is located on the blade and oppresses mutually with the spring leaf that handle of a knife is provided with.

Described projection is made as half garden shape.

Described blade is provided with and is used to control the dialing part that blade outwards ejects.

A drawing of described spring leaf and handle of a knife is connected as a single entity.

Described handle of a knife is provided with the latch fitting that is used to pin blade, and the favourable root that withstands on blade when blade launches of this latch fitting prevents user's stressed phenomenon of back amounting to of blade in use with blade lock.

Described blade is provided with the projection that blade outwards can be ejected, this projection fixedly is located on the blade and oppresses mutually with the spring leaf that handle of a knife is provided with, when rotating to the plane that spring leaf is provided with on the plane of half garden shape projection, it plays the effect of fixed blade, also assemble simultaneously the elastic force that blade outwards can be ejected is arranged, when needs blade of the present utility model launches, gently stir dialing part with have gentle hands, the blade of amounting in handle of a knife just ejects to user mode automatically.

The utility model compared with prior art has following advantage:

The utility model adopts a spring leaf and a drawing of handle of a knife, spring leaf and handle of a knife are connected as a single entity, its modular construction is oversimplified, reduced manufacturing procedure, and assemble up very easyly, and reaching and save resource and reduce manufacturing cost, it is simple in structure, be skillfully constructed, be subjected to consumer's welcome deeply.

Description of drawings

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is an internal structure schematic diagram of the present utility model;

Accompanying drawing 3 blade vertical stratification schematic diagrames of the present utility model;

Accompanying drawing 4 is equivalent in handle of a knife inner structure schematic diagram for blade of the present utility model;

Accompanying drawing 5 is a blade structure schematic diagram of the present utility model.

The specific embodiment

Come the utility model is further described below in conjunction with Figure of description:

Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4, accompanying drawing 5, a kind of novel spring pocket knife, comprise handle of a knife 1 and be connected on the handle of a knife and can be equivalent in blade 2 in the handle of a knife, described blade is provided with the projection 3 that blade outwards can be ejected, and this projection fixedly is located at the spring leaf 4 that is provided with handle of a knife on the blade and oppresses mutually.

Described projection 3 is made as half garden shape.

Described blade is provided with and is used to control 5 dialing parts that blade outwards ejects.

Described spring leaf 4 is connected as a single entity with a drawing of handle of a knife.

Described handle of a knife is provided with the latch fitting 6 that is used to pin blade, and the favourable root that withstands on blade 2 when blade 2 launches of this latch fitting has prevented user's blade 2 stressed phenomenons of back amounting in use with blade lock.

General workflow of the present utility model will be described below:

When needs are amounted to blade of the present utility model, the latch fitting 6 that at first will withstand on blade 2 roots is pushed aside, then blade is equivalent in fully the inner chamber of handle of a knife 1, at this moment, when the shape plane, half garden of projection 3 rotates to the plane that spring leaf 4 is provided with, play the effect of fixed blade 2, also assemble simultaneously the elastic force that blade 2 outwards can be ejected is arranged, when needs blade of the present utility model launches, at first gently stir dialing part 5 with have gentle hands, utilize projection 3 and spring leaf 4 to oppress the elastic force that produces mutually, the blade that will amount in handle of a knife ejects to user mode, as accompanying drawing 1.
