One of cutter is the common tool of people's daily life and operation, and indispensable instrument of the outgoing operation of people.
At present, releasing on market has the multi-form cutter of species for being adapted to that difference occasion is used, such as, a kind of safety cutter,
During use, finger presses out knife push button and releases blade, and finger on knife push button is decontroled out with after, in blade automatic rebounding retraction knife shell, can
To avoid causing to accidentally injure in use.And, the blade housing head bottom of this novel cutter is additionally provided with to be easy to cut cord
Opening cutter groove, solve the problems, such as that common cutter cutting cord easily skids.Make to be adapted to the larger different areas of activity of intensity
Knife shell with, this cutter is using being made by zinc alloy diecasting, but the metal blade table for being made by zinc alloy diecasting at present
Face all smoothers, larger blade of exerting oneself during use are easy to slip from handss, are to increase friction when metal blade surface is held
Power, has producer to be proposed in the handshake part of metal blade housing using bonding mode coating gluing cortex, but this mode makes
Due to firmly and adhesive-layer is aging makes rubber layer be easy to come off, causing cutter use, thus, it is necessary to enter one with
Step is improved.
Utility model content
The purpose of this utility model is the problems referred to above existed for prior art, there is provided a kind of kirsite in cutter
The shank section of the metal blade housing that die casting makes is coated using snap-fit attachment and is combined by plastic bottom layer and rubber top layer
The housing of making, in solving the problems, such as cutter use, holding frictional force is inadequate, meanwhile, extend the use longevity of cutter
Life.
The technical scheme adopted by this utility model is：A kind of safety cutter, including by upper shell and lower house fastening
The blade of composition, is provided with out knife push button in the knife back middle front part of blade, and the side of blade head is provided with changing of automatically replying
Blade push button, is provided with the drive mechanism equipped with blade in the housing of blade, it is characterised in that：The blade handshake part it is upper
The outer surface of housing and lower house is fastened and connected and is coated with skid-proof rubber shell and lower skid-proof rubber shell, upper skid-proof rubber shell by gluing shell outside
Layer and the compound composition of upper plastic housing internal layer, lower skid-proof rubber shell are constituted by lower glue shell outer layer and lower plastic housing internal layer are compound.
Further, described upper and lower skid-proof rubber shell, inside and outside layer housing internal layer ABS plastic and outer layer is respectively adopted
TPR plastic materials are made by two-shot molding process.
Further, the surface of described upper skid-proof rubber shell and lower skid-proof rubber shell is provided with frosted stricture of vagina or dermatoglyph face.
Compared with prior art, the utility model has the advantage of：In the steel edge that the zinc alloy diecasting of cutter makes
The shank section of body housing is coated by plastic bottom layer and the housing of rubber top layer produced with combination using snap-fit attachment, be increased
Blade handle of a knife hold when frictional force, effectively prevent hold skid, to using bring safety and convenience.
