Abstract

The utility model relates to a ceramic wire cutter, comprising a movably connected cutter handle. A groove for installing blades is arranged at the front end of the cutter handle and the blades are inserted into the groove; wherein one blade is metallic, and the other is ceramic. Owing to the continuous friction of the ceramic blade and the metal blade during the shearing process, the ceramic blade is taken as a grindstone and makes the cutting edge of the metal blade continuously sharpened for keeping the sharpness of the wire cutter. Both of the blades are smoothly contacted with good conjunction. The cutter handle adopts non-metallic material, which makes the whole wire cutter not rusty and clipped. The both blades that are stuck or locked are inserted into the groove for installing the blades. The utility model has the advantages that the blades can be replaced and the cost can be saved.

Description

A kind of ceramic thread is cut

Technical field

The utility model relates to the hand cutting tool technical field, and particularly a kind of line that is provided with ceramic tip is cut.

Background technology

Traditional scissors is made by metal material, because the metal blade is wearing and tearing mutually, after use a period of time, passivation phenomenon just occurs during shearing; Have corrosive material and easily get rusty because metal material is stained with water or other, therefore can produce chucking phenomenon and passivation phenomenon; Traditional scissors does not have separable blade, after the blade passivation, sharpens blade except needs, is exactly the scissors that more renews.

Summary of the invention

The purpose of this utility model provide a kind of can keep blade sharp, avoid scissors to use getting rusty after a period of time and ceramic thread that phenomenon occurs tightening is cut.

The technical scheme that realizes the utility model purpose is:

A kind of ceramic thread is cut, and comprises the handle of cutting of flexible connection, it is characterized in that: be provided with blade at the front end of cutting handle groove is installed, blade is installed in the groove, and one of them blade is a metal blade, and another blade is a ceramic tip.

The described handle of cutting is two hinged forming of end, cuts handle coincidence place inboard at two and is provided with return spring, cuts the handle middle part at two and is respectively equipped with stopper slot, limited post, and limited post is arranged in stopper slot, and constituting the front end of cutting handle can opening and closing in the scope of stopper slot.The gluing respectively blade of cutting the handle front end that is flush-mounted in of described two blades is installed in the groove.

The described handle of cutting is " U " font, " U " but to cut the front end of handle be the elasticity opening and closing to font, constituting the front end of cutting handle can opening and closing in the width range of " U " font.Described two blades setting-in respectively are locked in the blade installation groove of cutting the handle front end.

Ceramic thread provided by the utility model is cut, a blade is a metal blade, another blade is that the ceramic thread of ceramic tip is cut, have the following advantages: owing to the continuous friction of ceramic tip in shear history and metal blade, ceramic tip is equivalent to whetstone, and the blade of metal blade is constantly sharpened, with retention wire cut sharp, smooth contact between two blades agrees with good; Cut handle and generally can select nonmetallic materials for use, therefore whole line is cut the chucking that can not get rusty; Gluing or the locking of two blades is flush-mounted in blade and installs in the groove, and changeable blade is saved cost.

The specific embodiment

Embodiment one: as Fig. 1, Fig. 2, shown in Figure 3.Nonmetal to cut handle 1,2 stacked mutually by left and right two, terminally is movably hinged by rivet 5, and the nonmetal handle of cutting selects for use engineering plastics to be made; Be provided with blade at the front end of cutting handle 1,2 groove 13 is installed, blade inserts groove 13 and is adhesive in the end of cutting handle, wherein: left blade 3 is a metal blade, and right blade 4 is a ceramic tip, as long as just get rid of when changing blade and stickingly be embedded in the old blade of cutting on the handle and can change new blade; Cutting the inboard set return spring 11 of handle coincidence place at two places in the containing cavity 9,10 of cutting handle 1,2 inboards; A left side is cut handle 1 middle part and is offered stopper slot 7, and the right side is cut handle 2 and is provided with the limited post 12 that is mated and is inserted in wherein, the displacement of stopper slot 7 control limited posts 12, i.e. and the opening and closing degree cut of constrained line has chucking to cut the limited screw 8 of handle 1,2 at the end face lock of limited post 12; Left side blade 3 is made for ceramic material, and right blade is that metal material is made; The front end finger presses place of cutting handle 1,2 is provided with deep-slotted chip breaker 14 according to the physiological characteristic of human finger, and deep-slotted chip breaker 14 surfaces are provided with anti-skidding ripple glaze 6, and finger skids when preventing from firmly to shear, and makes and shears accurately.

Embodiment two: as shown in Figure 4.Cut handle 15 and be " U " font, cut handle 15 and select the engineering plastics one-shot forming for use, form " U " but to cut the front end of handle 15 be the elasticity opening and closing to font; The front end of cutting handle 15 is provided with blade groove 16 is installed, left and right blade 17,18 by screw 19 respectively setting-in be locked in the groove 16, wherein: left blade 17 is a metal blade, right blade 18 be a ceramic tip, takes off old blade and just can change new blade easily as long as lay down screw 19 during the replacing blade.Because " U " but the elasticity opening and closing of shape mouth, constituting the front end cut handle 15 can opening and closing in the width range of " U " shape mouth.
