Abstract

The utility model relates to a folding knife comprising a knife holder and a blade which is connected to the knife holder and can be folded in the knife holder. The blade is provided with a control element with a spring. The spring is arranged in a guide sleeve provided for the blade and supports the control element to move in the guide sleeve. A spring strip which supports the blade to eject outwards is arranged in the knife holder. One end of the spring strip is arranged in a spring seat arranged in an inner cavity of the knife holder, and the other end thereof is supported at the root part of the blade. The folding knife adopts the control element which is arranged on the blade and controls the unfolding of the blade. The gentle press of the control element causes the blade to eject out of the inner cavity of the knife holder in a semiautomatic manner and to unfold to a use state. The folding knife utilizes a locking element to support the root part of the blade, thereby effectively ensuring that no backward folding of the blade under a stress occurs when a user uses the folding knife. When the blade is folded in the inner cavity of the knife holder, convex grains of the locking element are clamped and inserted in recessed holes on the blade so as to lock the blade, therefore, when carrying the folding knife, the user is not damaged due to the unfolding of the blade. The folding knife has a simple structure and a smart design and is deeply welcomed by costumers.

Description

A kind of clasp knife

Technical field

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

Background technology

At present, the clasp knife kind of being sold on the existing market is of all kinds, and the folding pocket knife of the type is simple in structure, easy to use, is subjected to each consumer's welcome deeply.But present most of clasp knife all is to rely on manually blade is launched in handle of a knife, it is not very convenient using, the particularly new clasp knife of buying is because parts contact tough puckery, be difficult to blade is launched in the handle of a knife, thereby realize that it is creation main points of the present utility model that blade semi-automatic ejection in the handle of a knife launches.

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 make things convenient for blade to eject a kind of clasp knife that launches in handle of a knife.

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

A kind of clasp 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 control of band spring, and it is movable in guide pin bushing that spring is located in the guide pin bushing that blade is provided with a top control.

Be provided with the spring that a top blade outwards ejects in the described handle of a knife, an end of this spring is located on the spring base that the handle of a knife inner chamber is provided with, and the other end props up on the root that withstands on blade.

Also be provided with the latch fitting that is used to pin blade on the described handle of a knife, one end of this latch fitting is provided with protruding shrinkage pool that is provided with blade inlay card mutually, this latch fitting is favourable when blade is equivalent in the handle of a knife inner chamber, utilize an end of latch fitting to be provided with protruding grain, the shrinkage pool that is provided with blade inlay card mutually pins blade, has avoided user's blade when carrying the utility model to launch and injures the user.

The utility model compared with prior art has following advantage:

The utility model adopts and be provided with the control that the control blade launches on blade, press the control blade gently and be expanded to user mode with semi-automatic inner chamber ejection from handle of a knife, very easy to use, and also be provided with the latch fitting that can pin blade on the handle of a knife, latch fitting withstands on the root of blade when blade launches, guaranteed that effectively the stressed phenomenon of back amounting to of blade can not appear in user in use, when blade is amounted at the handle of a knife inner chamber, the protruding grain inlay card that latch fitting is provided with pins blade on the shrinkage pool that blade is provided with, avoided user's blade when carrying the utility model to launch and injure the user, it is simple in structure, is skillfully constructed, and is very popular.

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, accompanying drawing 6, a kind of clasp 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 control 3 of band spring 4, and spring is located at 5 interior top controls of guide pin bushing activity in guide pin bushing that blade is provided with.

Be provided with the spring 6 that a top blade outwards ejects in the described handle of a knife, an end of this spring is located on the spring base 7 that the handle of a knife inner chamber is provided with, and the other end props up on the root that withstands on blade.

Also be provided with the latch fitting 8 that is used to pin blade on the described handle of a knife, one end of this latch fitting is provided with shrinkage pool 10 that protruding grain 9 and blade be provided with inlay card mutually, this latch fitting is favourable when blade is equivalent in the handle of a knife inner chamber, utilize an end of latch fitting to be provided with protruding grain, the shrinkage pool that is provided with blade inlay card mutually pins blade, has avoided user's blade when carrying the utility model to launch and injures the user.

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 8 that at first will withstand on blade 2 roots is pushed aside, then blade is equivalent in fully handle of a knife 1 inner chamber, at this moment, protruding grain 9 inlay cards that latch fitting is provided with pin blade at the shrinkage pool 10 that blade is provided with, avoided user's blade when carrying the utility model to launch and injure the user, when needs blade of the present utility model launches, at first control 3 being pressed latch fitting 8 backed down is separated protruding grain 9 and shrinkage pool 10, at this moment, the elastic force that spring 6 was gathered when latch fitting 8 discharged outwards props up the top with blade 2, blade is propped up from the handle of a knife inner chamber eject, thereby realize the semi-automatic process of launching in the handle of a knife of blade, so repeatedly.
