Description

Cutter is drawn in practicality with blade baffle

Technical field

The cutter field that the present invention relates to relates in particular to a kind of practicality with blade baffle and draws cutter.

Background technology

Draw cutter, a kind of as cutter can be used on the scraps of paper, plastic plate etc., mark septal line usually; Be beneficial to tear or cut; For example the spaced openings on the stamp plate etc. is drawn a cutter and can be realized such opening, owing to draw the sharp easy damage of blade of cutter; And blade stretches out outside the cutter, when not using, damages outer body easily.For this reason, designer of the present invention is because above-mentioned defective through concentrating on studies and designing, comprehensively is engaged in for a long time the experience and the achievement of related industry for many years, and research and design goes out a kind of practicality with blade baffle and draws cutter, to overcome above-mentioned defective.

Summary of the invention

The object of the present invention is to provide a kind of practicality with blade baffle to draw cutter, it is simple in structure, and is easy-to-use, can when not using, effectively protect blade.

For realizing above-mentioned purpose, the invention discloses a kind of practicality and draw cutter with blade baffle, this practicality is drawn cutter and is comprised cutter body; This cutter body is long and narrow handle shape parts, and its front end has inclined groove, extends blade holder from this groove; The front portion of this blade holder is a semi-circular plate, and circle centre position has through hole with fixed blade, and this blade is the disk blade with intermediate throughholes; Be intervally distributed with a plurality of compact arranged blades on its disk to form cut, it is characterized in that:

Between blade and blade holder, be provided with the blade baffle, this blade baffle is made up of two parts, comprises the anterior circular slab and the elongated plates at rear portion, and the diameter of this circular slab is greater than the diameter of this blade.

Wherein: the middle part of this circular slab has oval slotted hole and oval protruding.

Wherein: have fastening bolt, pad and clamp nut on the through hole of blade holder, this fastening bolt meshes with clamp nut after passing oval slotted hole and the pad of through hole, circular slab of intermediate throughholes, the blade holder of blade successively.

Wherein: this elongated plates comprises the lug boss at middle part and the male part of both sides; The lug boss at this middle part is provided with convexity so that promote whole blade baffle before and after the user, thereby can make circular slab surround the protective position of blade and expose between the use location of blade and move the guarantor.

Wherein: the male part of both sides is extended a flange respectively laterally; Corresponding with this flange is to be provided with corresponding preceding recess and back recesses in the both sides of inclined groove, wherein; When flange and preceding recess matching and fixing; This blade baffle is positioned at the protective position shown in the figure, and when flange and back recesses matching and fixing, the blade that this blade baffle is positioned at blade exposes the use location with the operation of can ruling.

Through said structure, the practical scribing cutter with blade baffle of the present invention has following advantage:

1, simple in structure, dismounting is convenient;

2, easy to operate, change quick;

3, can when not using, protect blade not stretch out, carry out cutting operation, more can effectively protect blade thus and blade is stretched out.

The present invention will further describe in detail through following specific embodiment, and further combine will obtain knowing more and significantly understanding to the explanation of accompanying drawing.

Description of drawings

Fig. 1 has shown that the practicality with blade baffle of the present invention draws the decomposing schematic representation of cutter.

Fig. 2 has shown that the practicality with blade baffle of the present invention draws the combination sketch map of cutter.

The specific embodiment

Referring to Fig. 1 and Fig. 2, shown that the practicality with blade baffle of the present invention draws the specific embodiment of cutter.

This practicality is drawn cutter and is comprised cutter body 10; This cutter body 10 is long and narrow handle shape parts, and its front end has inclined groove 18, extends blade holder 16 from this groove 18; The front portion of this blade holder 16 is a semi-circular plate; Circle centre position has through hole with fixed blade 14, and this blade 14 is intervally distributed with a plurality of compact arranged blades to form cut for having the disk blade of intermediate throughholes on its disk.

Wherein, Have fastening bolt 26, pad 30 and clamp nut 28 on the through hole of blade holder 16; This fastening bolt 26 passes the intermediate throughholes of blade 14, through hole and pad 30 backs and clamp nut 28 engagements of blade holder 16 successively, so that blade 14 is fastened on the blade holder 16.

Wherein, In order to protect blade when not using, not stretch out cutter; Between blade 14 and blade holder 16, be provided with blade baffle 38, this blade baffle 38 is made up of two parts, comprises the anterior circular slab 24 and the elongated plates at rear portion; The diameter of this circular slab 24 is greater than the diameter of this blade; The middle part of this circular slab 24 has oval slotted hole 32 and oval convexity 34, and this ellipse slotted hole 32 can hold fastening bolt 26 and pass, and preferably; The width of this ellipse slotted hole 32 is less than the diameter of the intermediate throughholes of blade 14; The width that has rectangular indentation 36 and rectangular indentation portion on this fastening bolt 26 equal this ellipse slotted hole 32 width so that the position of this rectangular indentation 36 smoothly through oval slotted hole 32, oval protruding 34 can make that blade 14 and circular slab 24 are spaced apart to be contacted with it with the blade of avoiding blade 14, thereby can not wear and tear blade.

This elongated plates comprises the lug boss 42 at middle part and the male part 40 and 44 of both sides; The lug boss 42 at this middle part is provided with convexity so that promote whole blade baffle 38 before and after the user, thereby can make circular slab 24 surround the protective position of blade and expose between the use location of blade and move the guarantor; The male part 40 and 44 of both sides is extended a flange respectively laterally; Corresponding with this flange is to be provided with corresponding preceding recess and back recesses in the both sides of inclined groove 18, wherein; When flange and preceding recess matching and fixing; This blade baffle 38 is positioned at protective position shown in Figure 1, and when flange and back recesses matching and fixing, the blade that this blade baffle 38 is positioned at blade 14 exposes the use location with the operation of can ruling.Through foregoing description, the present invention can effectively protect blade, has not only prolonged service life, also is convenient to safeguard and change.

It is obvious that, and above description and record only are for example rather than in order to limit disclosure of the present invention, application or use.Though described and be described in the drawings embodiment in an embodiment; But the optimal mode that the present invention does not limit by the accompanying drawing example and the conduct of describing is in an embodiment thought at present is with the specific examples of the instruction of embodiment of the present invention, and scope of the present invention will comprise any embodiment of the specification that falls into the front and appended claim.
