Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of cutter, especially relates to a kind of insurance cutter.
Background technology
Cutter also is commonly called as icking tool, is a kind of fine arts and make the cutter that artifacts are used, and mostly is to mould handle of a knife and blade two parts are formed, and is the drawing and pulling type structure.It is knife handle of metal that minority is also arranged, and blade mostly is angle, can fracture along the line of sheet body with blunt, the new knife edge occurs, the convenient use.Cutter has big or small multiple model.
When normally using, only uses cutter the point of a knife part usually, cutting, and carve, getting ready is main function.Though the cutter of this structure utilizes extensively, this cutter blade is very crisp, can not stretch out long blade during use, and the hardness of blade also has difference with durable (this is two notions in the cutter) because the blade quality is different in addition.Selecting for use also of handle of a knife should be selected according to hand-type.Also some defective is exactly in addition, and now a lot of cutters fracture for convenience and all can process on broken line technology, but these processing may be compared danger for left-handed people, should take more care during use; The no insurance institution of this cutter itself, blade separates with its protection structure easily under the effect of external force or stretches out, and makes to there is some potential safety hazards.
For this reason, people are by constantly being to improve and innovation, row as, in relevant document, a kind of cutter [ZL:200720103781.2 was once disclosed; CN:201055994Y], though this technical scheme has solved owing to the blade potential safety hazard that the broken line technology that exists brought that fractures for convenience, blade stretches out under the effect of external force easily and the potential safety hazard that causes still exists.
Summary of the invention
The purpose of this utility model is at the problems referred to above, a kind of compact conformation is provided, is provided with the cutter of safety structure.
For achieving the above object, the utility model has adopted following technical proposal: the insurance cutter, comprise handle of a knife and be connected its inner blade, described handle of a knife comprises housing, and this enclosure interior is fixed with the guide pin bushing in the sliding chamber of band, guide pin bushing is provided with fixedly blade in the sliding chamber, and can slide in guide pin bushing or fixing knife rest, it is characterized in that, described knife rest afterbody is provided with the snap close of projection, the housing afterbody also be provided with can with snap fit, realize the catching groove that knife rest is fixedlyed connected with housing.
In above-mentioned a kind of insurance cutter, described knife rest bottom is provided with is convenient to the button button that blade takes out.When structure has realized pressing standby knife rest tight locking button herein, the deformation force effect lower slide of the structure function of deviating from automatically herein.
In above-mentioned a kind of insurance cutter, described catching groove is slightly protruding at surface of shell.This structure is convenient under artificial effect, and arming realizes operate as normal.
Compared with prior art, this insurance cutter advantage is:
Because in the technical program, the knife rest afterbody is provided with the snap close of projection, the housing afterbody also be provided with can with the catching groove of snap fit.Therefore when the knife rest that blade is installed moves to the relevant position backward, can realize automatically that snap close and catching groove mix, stop knife rest that the possibility that arbitrarily is drawn out is arranged, avoid knife rest disengaging housing.
