Abstract

The utility model provides a knife which blade is replaced by self, a control plate which is operated and slide is arranged inside a shell and slides in the shell under the control of a push button arranged on the shell, to drive the blade to go through the opening end of the shell front end or close the blade into the shell, a capacity slot for clamping a blade is arranged at one side of the control plate, a blade room in which a plurality of blades are overlapped and positioned is arranged at the other side of the shell near the capacity slot of the control plate, an outer cover is arranged outside the blade room, and a flexibility body which pushes and holds up the blade is arranged inside the outer cover. Thus, when the blade is blunt and is replaced, the blade in the capacity slot is taken down only by pushing the control plate to the most front end of the opening end of the shell, and when the control plate retracts to the shell and is positioned, a blade of the most inside blades which are pushed and held up by the flexibility body of the outer cover will automatically fall into the capacity slot and complete replacement of the blade, so that users replace a blade more quickly and conveniently.

Description

Can change the cutter of blade voluntarily

Technical field

The utility model relates to the cutter in the hand knife that a kind of hand cutting tool field has adjustable blade, particularly relates to a kind of cutter that can change blade voluntarily.It is to be provided with the control strip that can operate slip in a housing, and be provided with a tank of establishing for a slice blade card in a side of control strip, in housing, be provided with in addition one can stacked multi-disc blade the blade chamber, blade in the blade chamber is pushed control strip to by an elastomer, when blade is changed with blunt and desire, only need control strip is pushed into the shell nozzle end foremost, blade in the tank can be taken off, and be set back in when locating in the housing at control strip, by elastomer a slice blade in the blade chamber is pushed in the tank automatically and finish the action of tool changing sheet.

Background technology

Cutter is the sharp weapon that people cut article always, for the demand of various different operatings is provided, so also occurred the cutter of multiple different types on the market, the product of a kind of person for " carpenter's cutter " wherein arranged, it is that assembling is provided with one and is trapezoidal blade in a housing, the knife edge of this blade is formed on trapezoidal long base, be blade to be released by the shell nozzle end when the user uses with the controlling organization that is arranged in the housing, and make an acute angle tip of blade convexedly stretch in hull outside, and can allow the user carry out cutting action easily.

Existing carpenter's cutter blade is different with the cutter blade that general art designing uses, because it must bear bigger strength in use, structural strength is stronger so its blade thickness is thicker, when the most advanced and sophisticated blunt of the acute angle that is used, as the cutter that can't use as the art designing fractureing of more than sections on blade reappeared sharp tip, it must be opened housing and the blade upset is used, or being about to blade behind the most advanced and sophisticated all blunts of two acute angles is upgraded.

By above-mentioned explanation as can be known, this type of carpenter is comparatively inconvenient on blade exchange with cutter, especially when the user realizes blade acute angle tip blunt, must be in blade uses, and user's desire is with blade upset or when changing blade, must be with ongoing work stoppage, this promptly causes the inconvenience of manipulating; When especially using this type of carpenter to operate with cutter, the user overwhelming majority can put on work gloves, more can bring inconvenience when desire is changed blade this moment, after often must ungloving, the user can carry out more changing jobs of blade, if in the work that continues in order to change blade interruption of work again and again, or gloves are taken off again put on, will inevitably have influence on the progress of work, to Job person and Yan Genghui badly influences the efficient of work.

If see it by another angle, this type of carpenter all is to be deposited in the Storage Box with the new blade of cutter, when changing, user's desire the housing of cutter must be opened, old blade is taken off, opening Storage Box taking-up one new blade then packs into, with cutter housing closure, Storage Box will be closed and is seated to the location simultaneously again, this kind elaborate formalities must cause the suitable inconvenience of user; When if the user does not carry the Storage Box of depositing new blade again, then can there be blade can supply the awkward situation of changing.This shows that above-mentioned existing cutter still has many defectives, and the assistant officer treats further to be improved.

Because above-mentioned existing this type of carpenter can't provide the defective of effective replacing blade structure with cutter, the design people is based on abundant practical experience and professional knowledge, actively studied innovation, through constantly research, design, and after studying sample and improvement repeatedly, create the utility model of true tool progressive and practicality finally.

Summary of the invention

Technical problem underlying to be solved in the utility model is, overcome the defective that existing cutter exists, and provide a kind of cutter that can change blade voluntarily, make it in a housing, be provided with the control strip that to operate slip, and be provided with a tank of establishing for a slice blade card in control strip one side, simultaneously housing one side be provided with one can stacked multi-disc blade the blade chamber, when user's desire is changed blade, only needing that control strip is pushed into the shell nozzle end takes off foremost and with the blade in the tank, can be set back in when locating in the housing at control strip, by elastomer a slice blade in the blade chamber is pushed the action of finishing the tool changing sheet in the tank automatically, rapider and more convenient when allowing the user change blade.

Another technical problem to be solved in the utility model is, a kind of cutter that can change blade voluntarily is provided, make its in a housing, be provided with one can stacked multi-disc blade the blade chamber, that is the user can deposit the multi-disc blade in this blade chamber, allow new blade carry with cutter, and more convenient when allowing user's desire change blade.
