Description

Large art designer's knife

The utility model relates to a kind of large-scale cutter.

Cutter is one of general carpenter or the indispensable instrument of technology, and be convenient the gripping and use, then there is large-scale cutter to come out, because razor sharpened razor-edge profit, its safe in utilization having to is considered, and with current existing large-scale art designing's blade, roughly is to be provided with a tool rest in its handle of a knife, the tool rest front end is provided with blade, the tool rest surface is provided with a push button, and tool rest outer room in handle of a knife is passed back and forth, and the push button rear end is provided with a lock-button again, under normal conditions, tool rest is to be in the state that can freely release, during use, then optionally tool rest is pushed out to suitable length, thereafter with the lock-button post-tensioning, tool rest can be locked on this position whereby.

But should locking design, in operation facility and security, all have and do not attain perfect regret, as previously mentioned, this tool rest must be in the opposite direction with the lock-button post-tensioning after release, just can enter a lock-out state, but this staged operation mode is obviously not prompt as quickly as possible convenient, this kind cutter is not before using again, and its tool rest is to be in the state that can freely release, and this moment is as playing for the child, it still can be released tool rest easily, and it is constituted a threat to safely, this shows that traditional large-scale cutter is bad because of the latch-up structure design, so have the convenient and shortcoming safe in utilization of influence operation, thereby remain further to be improved.

In view of this, this creator is through research and design in many ways, successfully create a kind of large-scale cutter that push action could unlock and release tool rest simultaneously that sees through eventually, and cutter can recover locking immediately after push action is removed, convenience in the time of not only can promoting operation whereby, simultaneously also because of being to be in the lock state before the tool rest, and guaranteed safe in utilization.

Therefore, main purpose of the present utility model is: the large-scale cutter that a kind of tool safety locking function is provided, its mainly be on a handle of a knife, establish one in the sheaf space can the inside and outside tool rest of passing, this tool rest front end is installed with blade, be provided with fixture block and press button on it in regular turn, wherein but fixture block below is provided with a spring jack-up itself and press button, and constitute a lock-out state, when pressing press button and fixture block is pressed down, then can unlock, and simultaneously tool rest be released, when press button discharges, just recover locking immediately, can make the operation of cutter more attain facility with this kind locking design, and better safety guarantee is provided.

The technical solution of the utility model is: the structural improvement that a kind of large-scale cutter is provided, it comprises a hollow handle of a knife, be divided into upper and lower sheaf space in this handle of a knife, be provided with a slide on it in the sheaf space, this slide is formed with relative continuous ratchet respectively in the both side edges of top end opening, the slide inner sliding sleeve has a tool rest again, and the intrinsic blade of its front end sleeve is characterized in that:

This tool rest surface is formed with a protuberance, and the central authorities of its end face and place, both sides are formed with medium pore and side opening respectively, are arranged with a spring in the two side holes, and the front and back sidewall of protuberance is formed with two catching grooves respectively again,

Protuberance at one end is formed with a draw-in groove that communicates with side opening again, is provided with the fixture block of a convex shape in this draw-in groove, and this fixture block is to press on the spring set in the side opening that communicates, under the normality, the permanent clip in fixture block two ends between the adjacent ratchet on the slide,

Chimeric relatively on the tool rest again have a press button, and press button bottom surface central authorities and front and back side are formed with a post piece and two hooks respectively, and be able to correspondence and wear and be fastened on the medium pore and catching groove on the tool rest,

Must press press button with said structure and make fixture block break away from ratchet on the slide, state just can unlock.

The large-scale cutter of aforementioned modified form, it is characterized in that: be in the lower layer space of this handle of a knife for placing spare blade, this blade is to fix with a secondary tool rest, this pair tool rest is a sheet, be formed with the shallow slot that an end is open shape on it, be formed with projection on the shallow slot, sheathed on it for the formed trepanning of blade rear end.

The large-scale cutter of aforementioned modified form is characterized in that: this handle of a knife rear end is arranged with a jack knife device, and jack knife device rearward end is formed with the jack knife groove.

The large-scale cutter of aforementioned modified form is characterized in that: the protuberance front side wall of this tool rest is formed with between two catching grooves wears groove, and this is worn and is arranged with a shell fragment in the groove, can correspondingly support and pull on the adjacent ratchet of slide respective side.

Therefore, effect of the present utility model is mainly established a tool rest in the sheaf space on a handle of a knife, its lower floor can supply the plant spare blade, wherein the tool rest front end is fixed with blade, chimeric on it have a press button, be provided with a fixture block between this press button and tool rest, press button and fixture block are subjected to the jacking of a spring under the normality, and make tool rest be in a lock-out state, and wait and press press button fixture block is pressed down, then lock-out state is removed, tool rest can be released blade for using, and after discharging press button with the tool rest locking, utilize this locking design, can make the use of the large-scale cutter safety that more becomes.Utilize the combination of this tool rest, press button and fixture block, can make this tool rest press the back at press button is released simultaneously, and locked immediately, thereby can provide a convenient practical large-scale cutter, and this tool rest is the also constant lock-out state that maintains before not stretching out, and can guarantee that it is absolutely safe, so the utility model has had remarkable efficacy and has promoted than the large-scale cutter of tradition.

Further specify specific structural features of the present utility model and purpose below in conjunction with accompanying drawing.
