Description
Technical field
The present invention relates to a kind of technical field of cutter, specifically a kind of can the cutter of running fire.
Background technology
Cutter is a kind of common hand tools, is commonly used to cutting paper, leather, plastic sheet or hardboard etc.Existing cutter kind is a lot, in order to more allowing blade replacement is convenient, a lot of cutters that market occurs have the function of standby cutter, as the patent No. be 99243187.5 Chinese patent " a kind of cutter " by housing is provided with band blade, mobile button, cutter lock tool rest form, described housing connects into entirety by upper casing, lower casing and forms, and is also connected with standby cutter box in upper and lower shell.Promote mobile button during use, make blade stretch out outside housing, pin tool rest with cutter lock and just can use.To exchange blade, pressing for the hidden discount on cutter box, release standby cutter box, take out blade, upper casing opened by screw of outwarding winding, and exchanges.This complicated structure, more during allowing blade replacement, the screw that also needs to outward winding just can carry out, can not automatically change, tool changing operation is cumbersome, can not running fire, and does not have shift function, can not position according to the needs of blade flex length when using, therefore structurally also need further improvement.
Summary of the invention
Technical problem to be solved by this invention is the cutter providing a kind of structure simple, easy to assembly for the above-mentioned state of the art, not only has rapid changing knife function, and can carry out adjustment use according to the needs of blade flex length when using.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of cutter, comprise shell, slidably knife rest is provided with in shell, the head of shell is provided with the opening for blade flex, described knife rest is located in the cavity of shell slidably, knife rest is provided with the push button that has the trend of popping up, the upper edge of described shell be provided be convenient to push button slide push away groove, it is characterized in that: described knife rest is provided with the lock dog for locking blade, shell is provided with the corresponding allowing blade replacement switch for opening lock dog, the position described shell corresponding to the blade that knife rest is fully retracted under state offers one for cutter groove, standby cutter groove is provided with the fixed block for fixing spare blade corresponding with the bayonet socket on spare blade, the outside of standby cutter groove is provided with standby cutter lid, the inwall of standby cutter lid is provided with the spring leaf offseted with spare blade, spare blade is made to have inwardly to offset with knife rest all the time and realize the automatic trend changed.
As improvement, described knife rest is magnetic knife rest, the front of knife rest forms the suction cutter groove for placing blade, the position corresponding to the bayonet socket of blade in the upper end of inhaling cutter groove is provided with a mount pad can inserted for lock dog, mount pad is provided with projection, described lock dog is provided with the through hole corresponding with projection, the outside portion of lock dog is provided with the projection matched with the bayonet socket of blade, described lock dog is fixedly placed in mount pad by through hole with coordinating of projection, between the inner side and mount pad of lock dog, be provided with lock dog spring, lock dog is had all the time outwards and the trend of insert retention.
As improvement, the upper front end of described shell has an installation slotted eye, described allowing blade replacement switch is placed in by pin and installs slotted eye, when knife rest slides into outermost, inner end pin and the lock dog of described allowing blade replacement switch just in time offset, under tool changing state, press allowing blade replacement switch, the elastic force that lock dog overcomes lock dog spring is inwardly movable, projection outside it is separated with the bayonet socket of blade, meanwhile, described spare blade moves inward disengaging fixed block, enters and inhale realization replacing automatically in cutter groove under the effect of spring leaf.
As improvement, described shell is involuted by upper cover and base, upper cover and the involutory rear formation of base can be inserted and the cavity slided for knife rest, and can for push button slide push away groove, the inwall pushing away groove is provided with some groups can for the gear groove of push button location, the sidepiece of described push button is provided with the card base of locating with this gear slot fit, the inboard, upper end of described knife rest is provided with the jack can inserted for the lower end of push button, and between the bottom and jack of push button, be provided with a support spring, trend push button being had pop up all the time.Such push button is located at by knife rest and is pushed away in groove, and is with movable knife rack to slide along pushing away groove, is positioned simultaneously, thus realize the flexible of blade and gear location by card base and described gear slot fit.
Improve again, described standby cutter groove is opened in the front portion of upper cover, cover on outside standby cutter groove be provided with a front opening can the incense cutter lid chute of inserting, the downside of chute has a draw-in groove, the position that described standby cutter covers corresponding to draw-in groove is provided with one for cutter lid switch, described standby cutter lid is placed in chute, is locked with coordinating of draw-in groove by standby cutter lid switch with upper cover.
Improve again, described standby cutter lid adopts plastic rubber shaping part, cover at standby cutter and offer one for installing the mounting hole of standby cutter lid switch, the lower end of described standby cutter lid switch forms the buckle matched with described draw-in groove, described standby cutter lid switch can be limited in mounting hole up and downly, and a spring is supported with between the upper end of mounting hole and standby cutter lid switch, make standby cutter lid switch have the trend moving downward all the time and lock with draw-in groove.
Further improvement, inner side and the upper and lower inwall of described chute are provided with some slots, described standby cutter lid switch is provided with corresponding cutting, and described standby cutter lid switch is placed in chute by cutting with coordinating of slot, and is locked with coordinating of draw-in groove by standby cutter lid switch.
Further improvement, described gear groove is three ~ tetra-, is opened in respectively on the top inwall of base and upper cover, and on the inwall of base, form the guide rail that can slide for knife rest.
Improve further, the afterbody inwall of described base is provided with a joint pin again, and the afterbody of described upper cover is provided with corresponding counterbore, is connected by screw fixing, described base and upper cover involutory after form a hanging hole that can be used for hanging at upper rear.
Another improves, and the improvement of standby cutter lid open-close ways, the invention has the advantages that during product falls that there is not standby cutter lid automatically opens or drop thus cause blade to drop out the generation of this problem.
Finally, described upper cover and base involutory after above front end, be provided with blade guard, outside rear end, be coated with plastic sheath.
Compared with prior art, the invention has the advantages that: easy to use, only need press also driven forward push button and can be with movable knife rack forward slip, be pull-in on blade on knife rest also along with shell is stretched out in slip simultaneously, when push button activity is to gear groove, can position according to the needs of blade flex length when using, need more allowing blade replacement time, can by under blade fast fetching as long as press allowing blade replacement switch, the spare blade simultaneously in standby cutter groove automatically enters to inhale in cutter groove and realizes automatic quick-replaceable.Structure of the present invention is simple, easy to assembly, not only has running fire function, and can according to blade flex length when using need carry out gear location.
