Abstract

The utility model relates to a safe utility cutter, which comprises a cutter handle with an built-in chute and a blade with a snap line. The utility model is characterized in that: the blade and the chute is inserted into each other for assembling, one side of the cutter handle is provided with a long hole, the long hole is provided with a fastening screw for locking the cutter, an outwards extending guard ring is arranged at the front end of the cutter handle, a breaker is arranged at the front end of the cutter handle and a thin gap to be inserted by a cuter blade is arranged in middle of the breaker; a magnetic breaker is provided so that the cutter is safer when the cutter blade is broken and cutter blade could be prevented flying out; meanwhile, the breaker can cover an extended end of the cutter blade of the handle to prevent the cutter blade out of the chute; a guarding ring is added to prevent fingers slide and move forwards while prevent accident that fingers are cut by a cutter blade.

Description

Safe cutter

Technical field

The utility model relates to the technical field of cutter articles for use, relates in particular to safe cutter.

Background technology

Cutter in the market also has built-in moving guide rail and has the handle of a knife of regulatory function and the formula blade that fractures, and is that 200520069109.7 Chinese utility model patent " novel cutter " (notification number is CN2772841Y) is exactly this type of design as the patent No..A kind of cutter that comprises handle of a knife and blade, blade is located in the insert groove of handle of a knife and is can move freely, be shaped on broken line on the blade, the handle of a knife though this kind cutter blade can be withdrawn, it is exposed that but its knife-edge still has, there is the possibility that blade skids off, leaves meeting causes damage to people or thing potential safety hazard like this; Moreover at blade abrasion, when needing to exert oneself snap blade, a joint blade that is fractureed easily bursts apart or disorderly flies, and then causes uncertain safe consequence.

Summary of the invention

Technical problem to be solved in the utility model is that the safe cutter of making guard ring before a kind of handle, wearing the blade fracturer is provided at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: safe cutter, comprise the handle of a knife of built-in slideway and be shaped on the blade of broken line, it is characterized in that: described blade is mutually embedded equipped with slideway, described handle of a knife one side is shaped on an elongated hole, is provided with the holding screw that can lock blade position in the described elongated hole; Described handle of a knife front end is shaped on outward extending guard ring, and the anterior cover of described handle of a knife is stamped fracturer, is shaped on the finedraw that can insert blade in the middle of this fracturer.

The technical measures of optimizing also comprise: above-mentioned fracturer is two magnet up and down, and its outside is surrounded by steel plate or resin sheet.

Fracturer is the piece of stainless steel that has magnetic.

Finedraw runs through structure for through type two.

Compared with prior art, the utility model is increased in the guard ring of handle front portion, is used to stop the slippage forward of finger; Set the fracturer that is shaped on finedraw simultaneously.Advantage of the present utility model is: set the fracturer that has magnetic, and safer when blade is fractureed, prevent flying out by the jack knife sheet; This fracturer can cover the external part of handle cutter simultaneously, prevents that the blade mistake from going out slideway; Increase guard ring, prevented to point slippage forward, take place with the accident that blade hurts mutually.

Description of drawings

Fig. 1 is the layout schematic diagram of the utility model embodiment.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Structure of the present utility model is seen shown in Figure 1.Figure grade explanation: handle of a knife 1, guard ring 11, elongated hole 12, holding screw 13, blade 2, fracturer 3, finedraw 31.

Safe cutter, the handle of a knife 1 and the blade 2 that comprise built-in slideway, slideway is the rectangular iron plate of band groove, the inner chamber that is embedded in handle of a knife is also fixing, its groove is embedded in formula and is fitted with blade 2, and these blade 2 one side surfaces are shaped on broken line, and this broken line is the oblique line of 45 degree certain depths, be shaped on an elongated hole 12 in handle of a knife 1 one sides, be provided with the holding screw 13 that can lock blade 2 positions in the described elongated hole 12; Be shaped on outward extending guard ring 11 at handle of a knife 1 front end, guard ring 11 can stop points slippage forward, plays the safeguard protection effect; Be stamped fracturer 3 at handle of a knife 1 anterior cover, be shaped on the finedraw 31 that can insert blade 2 in the middle of this fracturer 3, this finedraw 31 runs through structure for through type two.

Fracturer 3 is two magnet up and down, and its outside is surrounded by steel plate or resin sheet; Perhaps this fracturer 3 is for having the piece of stainless steel of magnetic.

The utility model is increased in the guard ring of handle front portion, is used to stop the slippage forward of finger; Set the fracturer that is shaped on finedraw simultaneously.Advantage of the present utility model is: set the fracturer that has magnetic, and safer when blade is fractureed, prevent flying out by the jack knife sheet; This fracturer can cover the external part of handle cutter simultaneously, prevents that the blade mistake from going out slideway; Increase guard ring, prevented to point slippage forward, take place with the accident that blade hurts mutually.

Though the utility model illustrates and describes by the reference preferred embodiment,, those skilled in the art should understand, and in the scope of claims, can do the various variation on form and the details.
