Description
Technical field
The utility model relates to cutting-tool engineering field, particularly relates to a kind of cutting tool.
Background technology
In circuit board factory, workman often need use paper knife (also known as, Jie's paper cutter or boundary's paper cutter) to the circuit board produced, carry out point plate, a deburring etc. and cut.Wherein, the paper knife that these workmans use, be generally in stationery market purchasing, its structure mainly comprises handle of a knife, tool rest and blade, and handle of a knife is connected by fixture with tool rest, blade is movably connected on the slot set by tool rest, the slot of tool rest is provided with pushing block, can push-and-pull blade by pushing block, controls the length that blade stretches out, and pushing block is provided with locking knob, can be fixed by locking knob or unclamp blade.But the weak point of this paper knife is: parts are more, complex structure, cause expensive; And workman needs the circuit board hardness that cuts higher, causes paper knife especially easily to damage, and then causes production cost higher; In addition, locking knob, to the compression of blade, cutting energetically under operational circumstances, easily loosens, and namely blade is fixing firm not.
Utility model content
The purpose of this utility model is to provide for the deficiencies in the prior art that a kind of structure is simple, low cost, can reuse, the cutting tool of blade fixation.
To achieve these goals, the utility model is by the following technical solutions:
A kind of cutting tool, comprise handle of a knife, blade, described handle of a knife offers the storage tank mated with described blade, and described blade is plugged in the storage tank of described handle of a knife; Described cutting tool also comprises screw, nut, the tail end of described blade offers fixing hole, described handle of a knife offers the through hole that several intervals are mated with the fixing hole of described blade uniformly, described screw passes the through hole of described handle of a knife and the fixing hole of blade from handle of a knife side, be connected with the described nut being positioned at handle of a knife opposite side again, described blade is fixedly connected with handle of a knife; And described blade is provided with some intervals breaks broken string uniformly.
Wherein, several through holes described are positioned at the middle front part of described handle of a knife, and the rear portion of described handle of a knife also offers the rear through hole for packing up blade.
Wherein, described nut is the nut that can manually unscrew, and described screw is provided with the step of the fixing hole for clamping described blade.
Wherein, described handle of a knife is bent by sheet metal to form.
The utility model beneficial effect is: parts of the present utility model are less, and structure is simple, so low cost; Further, when the blade of blade front end damages, the blade of front end can being broken disconnected along breaking broken string, continuing to use remaining blade, thus can reuse, cost, production cost are reduced; Further, the utility model directly blade is fixed on handle of a knife by screw, thus be not easy to loosen, and makes blade fixation.Therefore, cutting tool of the present utility model is specially adapted to cutting of circuit board.

Detailed description of the invention
In order to describe the technical solution of the utility model in detail, below in conjunction with the accompanying drawing of the utility model embodiment, clear, complete description is carried out to the technical scheme of the utility model embodiment.Obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of the utility model protection.
Please refer to Fig. 1 ~ 4, cutting tool of the present utility model, comprise handle of a knife 1, blade 2.Handle of a knife 1 offers the storage tank 11 mated with blade 2, and blade 2 is plugged in the storage tank 11 of handle of a knife 1, makes handle of a knife 1 be wrapped in the periphery of blade 2, when workman holds handle of a knife 1, can not hold blade.Cutting tool of the present utility model also comprises screw 3, nut 4, the tail end of blade 2 offers fixing hole 21, handle of a knife 1 offers the through hole 12 that several intervals are mated with the fixing hole 21 of blade 2 uniformly, screw 3 passes the through hole 12 of handle of a knife 1 and the fixing hole 21 of blade 2 from handle of a knife 1 side, be connected with the nut 4 being positioned at handle of a knife 1 opposite side again, blade 2 is fixedly connected with handle of a knife 1.This kind of fixed structure, structure is simple, is not easy to loosen, makes blade 2 fixation; When needing adjustment blade 2 to stretch out the length of storage tank 11, can back out screw 3, after blade 2 is pulled out suitable length, then by another through hole 12, tighten the screws 3 and fixed blade 2, so adjustment is also very convenient.
Further, blade 2 of the present utility model is provided with some intervals and breaks broken string 22 uniformly.When the blade of blade 2 front end damages (such as: damage because cutting harder circuit board), can break disconnected along breaking the blade 2 of broken string 22 by front end, to stretch out by unspoiled blade 2 below, namely continue to use remaining blade 2, thus can reuse, make full use of resource, cost, production cost are reduced.
Preferably, several through holes 12 are positioned at the middle front part of handle of a knife 1, and the rear portion of handle of a knife 1 also offers the rear through hole 13 for packing up blade 2.When not using, blade 2 can all be placed in the storage tank 11 of handle of a knife 1, then passes the rear through hole 13 of handle of a knife 1 and the fixing hole 21 of blade 2 by screw 3, is fixed by blade 2.This structure, simple and convenient.
Preferably, nut 4 is the nut that can manually unscrew, and namely workman can manually unscrew or tightening nuts 4, to adjust the operations such as the extension elongation of blade 2 easily, without the need to instrument, convenient and swift.As shown in Figure 4, screw 3 is provided with the step 31 of the fixing hole 21 for clamping blade 2, namely the diameter of the step 31 of screw 3 is slightly less than fixing hole 21 diameter of blade 2, when cutting tool of the present utility model is installed, step 31 just sticks in fixing hole 21, thus blade 2 is rocked hardly, fix very well.
Preferably, handle of a knife 1 is bent by sheet metal to form.Such as: first cut the sheet metal that one piece of size is applicable to, the precalculated position punching press through hole 12 then on this block sheet metal, then bent, namely obtained handle of a knife 1.This structure, simply, cost is extremely low, convenient for production.
Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection domain; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; the technical solution of the utility model is modified or equivalent replacement, all belong to protection domain of the present utility model.
