Abstract

The utility model discloses a handheld pressing and cutting tool for a decorative thin metal 90-degree fixing angle. The tool comprises a cutting pliers body. The cutting pliers body comprises a handle end and a clamp end, wherein the handle end and the clamp end are disposed at two sides centered on a rotating shaft. The clamp end is provided with a clamp edge used for cutting a lead wire. The handle end controls the clamp end to open or close. The clamp end is provided with a thin metal 90-degree gap cutter in front of the clamp edge. The thin metal 90-degree gap cutter comprises an upper cutter edge and a lower cutter edge. The lower cutter edge is a lower recess with right angle corners. The upper cutter edge is a protrusion with right angle corners matching the lower cutter edge. The tool is simple in structure, and simple and practical in operation. The conventional cutting pliers are slightly improved to achieve the function of cutting a thin metal 90-degree corner.

Description

A kind of for decorating the hand-held crush-cutting instrument with thin metal 90 degree sizing angles

Technical field

The utility model relates to hardware & tools, particularly a kind of for decorating the hand-held crush-cutting instrument with thin metal 90 degree sizing angles.

Background technology

Finishing and house ornamentation often can be used aluminum alloy bar or aluminium alloy sheet, various aluminum alloy bars is for the bound edge of body structure, aluminium alloy sheet is for the decoration of sheet material, for beautiful decoration, in the time running into the corner of casing, aluminum alloy bar need to be bent into an angle of 90 degrees and run into right angle bound edge during for sheet material when aluminium alloy sheet, also need to cut out 90 degree gap at right angle bound edge; Traditional working method is with ruler line, then cuts out one 90 degree gap with handsaw.The problem that this kind of method brought is: the technical requirement to workmen is high, is secondly that the speed of construction is slow; People are starved of a kind of instrument and substitute this working method for this reason, simplify working procedure, increase work efficiency, and can ensure the quality of products.

Summary of the invention

The purpose of this utility model is that proposition is a kind of for decorating the hand-held crush-cutting instrument with thin metal 90 degree sizing angles, the front end of now widely used combination pliers is transformed into son, female cutting edge of a pair of 90 degree three bevel tools, make combination pliers both can cut off galvanized wire, again can be for the cutting of 90 degree gap of thin metal, make thin metal 90 spend knuckle accurate again soon.

To achieve these goals, scheme of the present utility model is: a kind of for decorating the hand-held crush-cutting instrument with thin metal 90 degree sizing angles: to have a combination pliers main body, described combination pliers main body is included in handle end and the clamp end that both sides arrange centered by rotating shaft, clamp end is useful on the card sword that cuts off galvanized wire, handle end control clamp end opens and closure, wherein, described clamp end is provided with thin metal 90 at the front end that is positioned at card sword and spends gap cutting knife, described 90 degree gap cutting knifes comprise the edge of a knife and the lower edge of a knife, the described lower edge of a knife is a lower recess that has right angle bead, the described upper edge of a knife is a projection that has the right angle bead matching with the lower edge of a knife, when the upper edge of a knife and the lower edge of a knife are clamped a sheet metal, when after the lower recess that has right angle bead of the edge of a knife under the tangent insertion of the projection that has right angle bead of the upper edge of a knife, on sheet metal, cut out a right angled triangle gap.

Scheme is further: the right angle bead of the described upper edge of a knife and the lower edge of a knife be a right angle forward, the middle bisector at right angle and the right angle bead that can overlap parallel with handle end decreased food direction center line.

Scheme is further: in the time of the described upper edge of a knife and the mutual interlock of the lower edge of a knife, the right angle bead plane of the described upper edge of a knife and the lower edge of a knife is that to intersect angle be the planes of 3 degree to 5 degree.

Scheme is further: the right angle bead plane of the described upper edge of a knife is parallel with the card sword face of clamp, and the right angle bead plane of the described lower edge of a knife is outward-dipping in card sword face, with the slanted angle of card sword face be that 3 degree are to 5 degree.

The beneficial effects of the utility model are: simple in structure, on existing combination pliers, transform into a little just can realize thin metal 90 degree gap cutting function, practicality simple to operate.

Below in conjunction with accompanying drawing and embodiment, the utility model is described further.

Fig. 2 is the utility model side view, the left view of Fig. 1;

Fig. 3 is that the utility model clamp end opens schematic diagram;

Fig. 4 is knife edge structure schematic diagram under the utility model, and the A of Fig. 3 is to view.

The specific embodiment

A kind of for decorating the hand-held crush-cutting instrument with thin metal 90 degree sizing angles: i.e. the hand-held crush-cutting instrument at metal sheet 90 degree sizing angles, chart 4 referring to Fig. 1, there is a combination pliers main body, described combination pliers main body is included in handle end 2 and the clamp end 3 that both sides arrange centered by rotating shaft 1, clamp end is useful on the card sword 3-1 that cuts off galvanized wire, handle end control clamp end opens and closure, wherein, described clamp end is provided with thin metal 90 at the front end that is positioned at card sword and spends gap cutting knife, described 90 degree gap cutting knifes comprise the edge of a knife 4 and the lower edge of a knife 5, the described lower edge of a knife is a recessed 5-2 who has right angle bead 5-1, recessed inner side is outward-dipping so that outstanding right angle bead, the cutting edge that guarantees right angle bead is sharper, the described upper edge of a knife is a protruding 4-2 who has the right angle bead 4-1 matching with the lower edge of a knife, when the upper edge of a knife and the lower edge of a knife are clamped a sheet metal, when the lower recess that has right angle bead of the edge of a knife under the tangent insertion of the projection that has right angle bead of the upper edge of a knife, can on sheet metal, cut out a right angled triangle gap.

In embodiment: the right angle bead of the described upper edge of a knife and the lower edge of a knife be a right angle a forward, the middle bisector 6 at right angle and the right angle bead that can overlap parallel with handle end decreased food direction center line 7, can certainly right angle a to the left or to the right, middle bisector 6 and the handle end decreased food direction center line 7 at right angle is the right angle bead of 90 degree angles, and this kind of form is not shown.

In embodiment: in the time of the described upper edge of a knife and the mutual interlock of the lower edge of a knife, the right angle bead plane of the described upper edge of a knife and the lower edge of a knife is that crossing angle is the planes of 3 degree to 5 degree; When the design of this kind of structure makes to cut blade intersect be a point rather than a line, cut laborsaving.

In embodiment: the right angle bead plane 4-3 of the described upper edge of a knife is parallel with the card sword face of clamp, the right angle bead plane 5-3 of the described lower edge of a knife is outward-dipping in card sword face, with the slanted angle 8 of card sword face be that 3 degree are to 5 degree.

The present embodiment is just in the cutting function that transforms a little the 90 degree gap that just can realize thin metal on existing combination pliers into, practicality simple to operate.
