Abstract

A spring knife comprises a knife handle and a blade connected with the knife handle and capable of being folded into the knife handle, wherein, a convex pillar for ejecting the blade outwards is arranged on the blade, the convex pillar is fixedly arranged on the blade and is pressed against a spring leaf arranged on the knife handle, the spring leaf is arranged in an arc position on the knife handle, the blade is provided with a poke piece for controlling the outward ejection of the blade, and the knife handle is provided with a lock piece for locking the blade. When the blade is unfolded, the lock piece can be propped against the root of the blade and locks the blade, so that the blade can be prevented from being folded in the reverse direction when in use. Since the spring leaf in the knife handle is pressed against the convex pillar arranged on the blade, the blade can be automatically ejected out from the knife handle through slightly poking at the poke piece with a hand, and enters the use mode. The spring knife has the advantages of simple structure and ingenious concept, and is popular among consumers.

Description

A kind of flick-knife

Technical field

The utility model relates to five metals cutter manufacturing technology field, is a kind of flick-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, and proper a kind of flick-knife attractive in appearance.

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

A kind of flick-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, and described blade is provided with and is used for projection that blade is outwards 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 semicircle.

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

Described spring leaf is located in the arc position that handle of a knife is provided with.

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 semicircle 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 is provided with spring leaf and oppresses mutually with the projection that blade is provided with in handle of a knife, the user gently stirs dialing part with have gentle hands, blade will be automatically from ejecting in the handle of a knife to user mode, and handle of a knife also is provided with latch fitting, 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, and 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 the utility model internal structure schematic diagram;

Accompanying drawing 3 is equivalent in handle of a knife inner structure schematic diagram for the utility model blade;

Accompanying drawing 4 is the utility model blade structure schematic diagram.

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, a kind of flick-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 and is used for the outside projection 3 that ejects of blade, 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 semicircle.

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

Described spring leaf 4 is located in the arc position 7 that handle of a knife is provided with.

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 semicircle plane 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.
