Description

Folding cutter

Technical field

The utility model relates to a kind of cutter, specifically, relates to a kind of folding cutter that is convenient for carrying.

Background technology

In daily life, cutter has become a kind of necessary tool.Carry for convenience, carried out various improvement on the structure of cutter, folding cutter is exactly wherein a kind of.Existing folding cutter is generally two parts: cutter shell and cutter hub, to insert in the groove of cutter shell after cutter hub is folding, and blade is accidentally injured human body when avoiding carrying.Though existing folding cutter has above-mentioned advantage, but still have shortcoming: two sections folding cutter volume after folding is still very big, and we generally are that cutter is hung on key chain when carrying, and cutter and key are just not really coordinated like this, influence attractive in appearancely, carry also and inconvenient.

The utility model content

The purpose of this utility model provides a kind of folding cutter of pattern novelty, makes it easy to carry, places with key that a time-out is coordinated mutually, overall image is more attractive in appearance.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of folding cutter, comprise cutter body, it is characterized in that, described cutter body is made up of at least two blades, on the front of blade or the back side, be provided with first groove and second groove, be provided with active link in first groove, be provided with steel disc in second groove, link to each other by active link between the adjacent knife blades.

Described blade increases successively from point of a knife to handle of a knife.

Described blade is widened gradually from point of a knife to handle of a knife.

The thickness of described blade is at least 2mm.

Described active link is a hinge.

The width of described first groove is greater than the width of second groove 0.1mm at least, and the degree of depth of first groove is less than the degree of depth of second groove 0.1mm at least.

Also be provided with spring in second groove of described cutter body shank end, on spring, be provided with and be used to the stopper that stops steel disc to be return, can make steel disc reply the returning spring of original state and in second groove of cutter body point of a knife end, also be provided with.

The length of described steel disc and the equal in length of respective blade.

In the utility model, cutter body utilizes hinge to be connected to form by some blades, and a groove is set on each blade, the fluted connection is a strip groove, a steel disc is set, in use in the groove, to push away before the steel disc, steel disc is connected in one two adjacent knife blades, the steel disc compression front springs of point of a knife end, and the barrier sheet of the steel disc of shank end below is upspring under spring action, stop that steel disc returns, at this moment, all blades are connected as a single entity, and can use; After the use, barrier sheet is pressed down, the steel disc in the blade is subjected to the effect of point of a knife end spring, all returns back to initial position, and steel disc is all got back in the groove of respective blade, is that waypoint is folded into triangle at last with the hinge with blade.

Accidentally injure human body for fear of blade, the width of blade is widened successively from point of a knife to handle of a knife, when folding, begins to fold from the point of a knife end, is positioned at innermost layer at folding rear knife edge like this, thereby avoids contacting with human body, accidentally injures human body.Steel disc can be arranged at the blade front, also can be arranged at the blade back side, is as the criterion not influence normal use of cutter.Be folding convenient, to handle of a knife, all blades increase successively, widen successively from point of a knife, wherein, the back one blade than last blade to the youthful and the elderly 1mm, than the wide 1mm of last blade, in actual production, blade lengths and width can change according to actual needs, being as the criterion by folding forming.When actual production, also can increase or reduce the number of blade, select suitable blade lengths and width, change folding shape, make the shape of tool after folding different, to satisfy different clients' needs.When hanging on key chain after cutter is folding, cutter promptly becomes a kind of ornaments on the key chain, makes whole key chain more attractive in appearance, for further improving security, also can be cutter and is equipped with corresponding tool envelope, make carry convenient.

The utility model is novel, designs ingeniously, simple in structure, and practicality easy to carry has very high practical value.

The specific embodiment

Below by giving an example the utility model is further specified.

As Fig. 1～shown in Figure 3, a kind of folding cutter, comprise cutter body, described cutter body is made up of seven blades 1, on the back side of blade 1, be provided with first groove 6 and second groove 7, it is a strip groove that second groove 7 of all blades 1 can be communicated with, wherein, first groove, 6 to the second grooves, 7 wide 0.5mm, than second groove, 7 shallow 0.2mm, being provided with in first groove 6 to be provided with in hinge 3, the second grooves 7 that are used to connect adjacent knife blades makes all blades 1 be connected to the steel disc 2 of fixing immutable integral body.Below the steel disc 2 of shank end, be provided with spring 5 and be used to the barrier sheet 4 that stops steel disc 2 to retreat, then be provided with at the point of a knife end and make steel disc 2 reply the spring 5 of original states.To handle of a knife, blade 1 increases successively from point of a knife, widens successively, and wherein, back one blade is than the long 1cm of last blade, and than the wide 1cm of last blade; All steel discs 2 are isometric with respective blade 1.

Using method: will push away before the steel disc 2, the two ends of each steel disc 2 are placed respectively on adjacent two blades 1, point of a knife end steel disc 2 compresses the spring 5 in its place ahead, and upspring under the effect of spring 5 thereunder of the barrier sheet 4 of shank end steel disc below, stop steel disc 2 to be return, at this moment, blade 1 no longer can arbitrarily change, all blades form the cutter that can normally use under steel disc 2 effects, hold handle of a knife, can use.After use, the barrier sheet 4 of shank end is pressed down, all steel discs 2 are at the effect of point of a knife end spring 5 rejuvenate beginning state next time, promptly all steel discs 2 are all got back in second groove 7 of its corresponding blade 1, at this moment, blade 1 loses the supporting role of steel disc 2, under the connection of hinge 3, can be that the strong point carries out circular motion with hinge 3, with hinge 3 is waypoint, begin to fold from point of a knife, seven blades are folded into triangle, and folding rear knife edge all is positioned at innermost layer, can avoid blade to contact, accidentally injure human body with human body.The folding cutter that is of moderate size hangs over key, becomes a kind of trimmings attractive in appearance on the key chain.
