Description

A kind of cutter
Technical field
The utility model relates to a kind of cutter, particularly a kind of cutter.
Background technology
Cutter also is commonly called as icking tool, is a kind of fine arts and make the cutter that artifacts are used, and is mostly to mould knife rest and blade two parts composition, and it is the metal knife rest that minority is also arranged, and is the drawing and pulling type structure.Mostly blade is angle, can fracture along the line of sheet body with blunt, the new knife edge occurs, the convenient use.
Please refer to Figure 1A, in conventional construction, when blade 92 stretches out knife rest 91 uses, by the positioning function of operating-controlling mechanism 93; Make blade 92 no longer mobile, remove, please refer to Fig. 1 up to positioning function; General cutter comprises knife rest 91 and blade 92, and knife rest 91 all is strip with blade 92; The cutter groove 911 of the set inside one ccontaining blade 92 of knife rest 91, the front end of this cutter groove 911 be provided with one can supply blade 92 to come in and go out open front, blade 92 can be urged into release along these cutter groove 911 directions; On the wherein sidewall of cutter groove 911 guide groove 912 is set, this guide groove 912 also is a strip, and its two edges are Saw blade, and its direction is identical with the direction of cutter groove 911.Also comprise an operating-controlling mechanism 93; This operating-controlling mechanism 93 can and be arranged in the guide groove 912 of knife rest 91 along the slip of guide groove 912 directions; This operating-controlling mechanism 93 passes this guide groove 912 and is fixedly connected with the end of blade 92; Promote operating-controlling mechanism 93, operating-controlling mechanism 93 moves in guide groove 912, and drive blade 92 slides together.Please refer to Figure 1B and Fig. 1 C, operating-controlling mechanism 93 comprises a slide block 931, this slide block 931 be located at knife rest 91 inside and can slippage.Slide block 931 trailing edges project upwards a pair of elasticity card article 932, these elasticity card article 932 terminal locating pieces 933 that form, and this locating piece 933 forms positioning action with the Saw blade interference of guide groove 912.In addition, one fixedly pushing block 934 belows be provided with a slip pushing block 935, control piece 936 and slip pushing block 935 bottom surfaces are provided with one.When slip pushing block 935 during near fixing pushing block 934, shown in Figure 1B, control piece 936 relatively away from locating piece 933, elasticity card article 932 can be freely swung, make operating-controlling mechanism 93 can in cutter groove 911, promote blade 92 displacements; When slip pushing block 935 during away from fixing pushing block 934; Shown in Fig. 1 C; Control piece 936 just in time between two locating pieces, 933 inside, elasticity card article 932 can not be freely swung, then operating-controlling mechanism 93 can't promote blade 92 displacements to reach the effect of location in cutter groove 911; The blade 92 that order is pushed out knife rest 91 is positioned and uses, in order to avoid cause danger because of blade 92 moves when using.
Yet the design of known techniques is that the position is between elasticity card article 932 owing to control piece 936 all the time; Even slip pushing block 935 pushes away near during to fixing pushing block 934, still between two elasticity card articles 932, the space that makes elasticity card article 932 to freely swing is little for controll block; Just blade 92 promotes the strength that displacement will be bigger; Produce the problem that promotion has some setbacks, especially when promoting blade 92, owing to control piece 936 still between two elasticity card articles 932; Make elasticity card article 932 be prone to the problem that fractures, influence service life.And this technology of convention, structure are too complicated, have not only increased the complexity of processing technology, but also have wasted material.
