Abstract

The utility model relates to a straight-out knife which comprises a knife handle and a cutting blade arranged inside the knife handle in a telescopic manner, wherein the knife handle is provided with a grooved cavity used for allowing the cutting blade to extend or retract inside the knife holder; a push rod is also arranged inside the knife handle and used for controlling the extension or retraction of the cutting blade; an upper projection and a lower projection are formed on the push rod; a main hook, an auxiliary hook and a spring are also arranged on the push rod; and the two ends of the spring are connected with the end parts of the main and the auxiliary hooks. The knife handle is provided with the grooved cavity that enables the extension or retraction of the cutting blade, and a rear clamping pin is arranged inside the knife handle and is embedded in a front recess arranged on the cutting blade to lock the cutting blade, thereby effectively preventing the cutting blade from automatically kicking up to hurt the user during the carrying. Additionally, a front clamping pin is arranged inside the knife handle, so that when the cutting blade kicks up from the inside of the knife handle, the front clamping pin pushes against the root part of the cutting blade, thereby effectively preventing the cutting blade from retracting under force to hurt the user when in use.

Description

A kind ofly directly go out pocket knife

Technical field

The utility model relates to five metals cutter manufacturing technology field, is a kind of pocket knife that directly goes out specifically.

Background technology

At present, sold on the market directly to go out the pocket knife kind of all kinds, the pocket knife of the type is simple in structure, and is easy to use, very popular.But mostly directly go out the object that pocket knife can only cut some flexibilities, at the higher object of some hardness ratios of cutting, the vallecular cavity retraction that blade will be provided with to handle of a knife is so the object of realizing pocket knife cutting high rigidity is the primary problem that solves of the utility model.

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, easy to use, and that can cut the high rigidity object a kind ofly directly goes out pocket knife.

The utility model is achieved through the following technical solutions:

A kind ofly directly go out pocket knife, comprise handle of a knife (1) and be arranged in the handle of a knife and telescopic blade (2), described handle of a knife is provided with the vallecular cavity (3) that can supply blade to stretch in handle of a knife, be provided with in the handle of a knife and can control the flexible push rod (4) of blade, push rod is provided with upper cam position (5) and lower cam position (6), also be provided with main hook spare (7), auxiliary hook spare (8) and spring (9) on the push rod, two of spring is connected with the end of major and minor hook spare.

Described handle of a knife top is provided with can control the flexible button (10) of blade, and this button is connected with the protruding position (5) that push rod is provided with.

Described handle of a knife is provided with the preceding bayonet lock (11) and the back bayonet lock (12) that can block blade.

Described blade is provided with steady pin (13), preceding recess (14) and back recess (15).

Described steady pin (13) contacts with main hook spare (7), and back recess (15) contacts with auxiliary hook spare (8), preceding recess (14) and back bayonet lock (12) inlay card mutually.

Described handle of a knife is made up of handle seat (16) and handle lid (17).

The utility model compared with prior art has following advantage:

The utility model is provided with at handle of a knife can be for the flexible vallecular cavity of blade, when not using pocket knife with in the blade retraction handle of a knife, utilize the back bayonet lock inlay card that is provided with in the handle of a knife on the preceding recess that blade is provided with, to pin blade, avoid when carrying blade to eject automatically and injure the user; And also be provided with preceding bayonet lock in the handle of a knife, when blade ejected use in handle of a knife, preceding bayonet lock withstood on the heel of blade, the phenomenon that effectively guarantees stressed the turning back of blade can not occur in use and injure the user, it is simple in structure, and is convenient and practical, welcome by consumers in general.
