Abstract

The utility model relates to a rotary artist's knife which is formed by a cavity body, a switch frame and blade driving device being connected with each other, wherein the cavity body is formed by a front knife handle and a rear knife handle which are provided with protective sheets; the switch frame which is arranged in the cavity body is provided with a switching key and a spring; the blade driving device is formed by blades placed on a knife disc and movably connected to the outer surface of one end of the front knife handle or that of the rear knife handle; the end head of a blade frame is also fixed with a shaft connected with the knife disc and can slide in holes in the front and the rear knife handles. The utility model which has the advantages of simple structure, less parts and easy fabrication can be assembled without tools. The knife disc is driven by the shaft on the switch frame to move forward and backward on a concave of the front knife handle as long as the switching key is moved forward and backward; when the knife disc is moved backward and retracted, the blades extend out and can cut at once; when not used, the knife disc extends forward and blocks off the blades, so the blades can not cut, which is convenient in operation and safe in use. The utility model which can cut straight lines or curved lines by adopting the disk-shaped blades has the advantages of smooth and continuous tangents, good cutting quality and high work efficiency, and can change the blades with different knife edges.

Description

The rotary type cutter

Technical field

The utility model relates to a kind of cutter, and the replaceable blade that has the different pattern blade cuts out the straight line of different decorative patterns, pattern or the rotary type cutter of curve.

Background technology

For satisfying the different demands of society, especially in career fields such as decoration, industrial art, advertising message, engraving, the cutting of edge of carpet lace, for increasing work efficiency, often need to use the cutting tool of various different structures, cutting tool various in style can select use for the consumer, but most cutters still adopt long blade on the existing market, only can cut some straight lines by it,, directly influence cut quality and attractive in appearance if the lines that cutting curve cuts out are not slick and sly, intermittent.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of rotary type cutter is provided, can not only cutting straight line, again can cutting curve, and line of cut is smooth, well-balanced, if the blade that transposing is different, can cut out the line of cut of different decorative patterns, pattern, high efficiency, easy to operate, safe in utilization, for market has increased new varieties again.

The technical scheme in the invention for solving the above technical problem is: the rotary type cutter, the switch frame of belt switch key, spring is installed in the cavity that forms by the forward and backward handle of a knife that has rubber fender, switch frame and blade drive connect to form, described blade drive, be placed in the cutterhead by blade, be connected with securing member on the outer surface of forward and backward handle of a knife one end and form, also be fixed with axle on the termination of described switch frame, axle is connected with cutterhead and can slippage in the hole on the forward and backward handle of a knife.

Compared with prior art, advantage of the present utility model is: this rotary type cutter only is made up of forward and backward handle of a knife, cutterhead, blade, securing member, switch frame, and is simple in structure, part is few, easy processing, all can assemble without instrument, easily produces in batches.As long as forward and backward mobile on ﹠ off switch, drive cutterhead forward and backward moving on the concave surface of preceding handle of a knife termination by the axle on the switch frame, behind cutterhead, move withdrawal, blade stretches out and can cut, time spent cutterhead reach is not stretched out, is blocked blade and can not cut, left hand and right hand all can be operated, and is easy to operate, safe in utilization.In addition because of it adopts disk shape blade, can not only cutting straight line, again can cutting curve, and also curvilinear cut is smooth, continuous, and cut quality is good, high efficiency.Change the blade of different blades, cut out the lace of different pattern, decorative pattern, the scope of application is wide.When cutterhead moves always the boss on the preceding handle of a knife forward or backward, open slot when switch frame moves on it and the locating piece on the handle of a knife of back cooperate, so the moving all the time steadily of cutterhead, accuracy are high.

The specific embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Forward and backward handle of a

knife

6,13 shapes, symmetrical configuration.

Preceding handle of a knife 6 inner surface edge have the seam and two locking grooves 20 of protrusion, guide rail, hook post 19 that protrusion is arranged in the inner surface pommel cavity, cylindricality joint pin, through hole, outer surface cutter end is a concave surface 4, on band boss 12 of through hole and out-of-line mounting hole 15 are arranged, the trade mark platform 9 of projection is arranged in the middle of the pommel.

Back handle of a knife 13 inner surface edge have groove and two locking grooves 20 that cooperate with seam, and corresponding protrusion guide rail, dog hole, the joint pin of band blind hole, through hole are arranged in the inner surface pommel cavity, protrude the other guide pad 21 that also has a waist shape of guide rail.Outer surface cutter end is a concave surface 4, on band boss 12 of through hole and out-of-line mounting hole 15 are arranged.

Blade 1 is a disc, and there is the polygon irregularly-shaped hole of trisection the centre, and an outer surface also has uniform scale.

Cutterhead 3 is round by size two, and is made up of the cascaded surface that flange 23 forms in the junction on two surfaces, and waist hole 22 is arranged in the great circle, and through hole 24 is arranged in the roundlet, and waist hole 22 and through hole 24 be not on same straight line, and be corresponding with mounting hole 15 with the boss 12 on the forward and backward handle of a knife.

Securing member is an attachment screw 2, and the one end is a surface plate, and an end is a stairstepping, and screw thread is arranged on the termination.

Switch frame 18, its openend one side is a detent 16, and side is the axle 5 of both sides five equilibrium and protrusion in addition, and both sides fuse with spring 17, and on ﹠ off switch 7 is arranged on the end face, also have an open slot 25 on the sidewall of blind end.
