Description

A kind of throw away tool

Technical field

The utility model relates to a kind of cutter, particularly relates to a kind of throw away tool.

Background technology

At present, the blade of general throw away tool on the market, the knife back is all narrow, when people when using cutter, such as when sharpening a pencil, because knife back place is not only narrow but also hard, when using cutter, the thumb of the push broach back of the body does not often feel well.

Patent Office of the People's Republic of China disclosed the utility model that a kind of name is called a kind of blade on July 1st, 2009, and its Granted publication number is CN 201264247Y.This utility model discloses a kind of pocket knife, comprise handle of a knife and be connected on the handle of a knife and can be equivalent in blade in the handle of a knife, described handle of a knife top is provided with spring, the recess that one end and the blade of this spring is provided with is clamp mutually, the other end is in the arc position that handle of a knife is provided with, described spring is realized the needed elastic force of blade in the set arc position of handle of a knife, the both sides, spring end that contacts with blade are revealed and done group key that the control blade is amounted to and opened.The weak point of this utility model is that its knife back place is narrow, and when using cutter, the thumb of the push broach back of the body can not feel well.

Summary of the invention

It is not only narrow but also hard that the purpose of this utility model is to solve general cutter knife back place, and when using cutter, the problem that the thumb of the push broach back of the body does not feel well provides a kind of comfortable throw away tool that uses.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of throw away tool, comprise that handle of a knife reaches and the hinged blade of handle of a knife, described blade back is provided with the strip buffer bar, the rubber-like buffer bar has avoided people's thumb when using cutter directly to contact the knife back, effectively solved the uncomfortable problem of thumb when using cutter, it is more comfortable that cutter is used.

As preferably, described buffer bar cross section takes the shape of the letter U, and described buffer bar is installed in blade back, conveniently assemble and disassemble.

As preferably, the thickness of described buffer bar equals the thickness of handle of a knife, and is in the time of in blade is folded to handle of a knife, more attractive in appearance.

The beneficial effect that the utlity model has is: knife back place has increased buffer bar, has avoided people's thumb when using cutter directly to contact the knife back, uses more comfortable, buffer bar is installed in the blade back, easy to loading and unloading, the thickness of buffer bar equals the thickness of handle of a knife, and is more attractive in appearance after cutter is amounted to.

Description of drawings

Fig. 1 is the utility model master TV structure schematic diagram;

Among the figure: 1. blade, 2. handle of a knife, 3. buffer bar.

The specific embodiment

Below by specific embodiment, and in conjunction with the accompanying drawings 1, the technical solution of the utility model is described in further detail.

As shown in Figure 1, a kind of throw away tool comprises that handle of a knife 2 reaches and the hinged blade 1 of handle of a knife, described blade 1 is provided with rubber-like strip buffer bar 3, described buffer bar 3 cross sections take the shape of the letter U, and described buffer bar 3 is installed in blade 2 backs, and the thickness of described buffer bar 3 equals the thickness of handle of a knife 2; Rubber-like buffer bar 3 has avoided people's thumb when using cutter directly to contact the knife back, effectively solved the uncomfortable problem of thumb when using cutter, when cleaning blade 1, only need buffer bar 3 is pulled down, after cleaning is finished, again buffer bar 3 is clipped on the knife back, when blade 1 is folded in the handle of a knife 2, because buffer bar 3 thickness equal handle of a knife 2 thickness, look as a whole, better appearance.
