Description

But the cutter of autocondensation

Technical field

The utility model relates to a kind of cutter, but especially refers to a kind of cutter of autocondensation.

Background technology

Generally when using cutter, the user can't cut a cutter with regard to retracting blade once at every turn, common occupation mode is that cutter is positioned on one side, so take up again to cut and once be positioned over again on one side, be accomplished to a paragraph up to work and just can blade be withdrawn and place in the body in manual mode.And cutter idle during, the cutter blade exposes, therefore tending to unexpected is that the situation of stabbing takes place with people's incised wound or with the people.

For preventing the generation of this contingency, the patent No. is that 00254795.3 Chinese utility model has proposed new structure, and its structure is for including:

One body is an elongate housing, and is inner at a room, this this long axis of body to two ends respectively be provided with an openings and be communicated with this room, a side of this body along major axis to being provided with an elongated hole;

One end fastener is microscler, is located at the openings place of body one end;

One guide member, be microscler, be through in this body, can be in this body along the major axis of this body to moving and outwards protruding out by the openings of this body other end, the end that protrudes out of this guide member is provided with a use breach, and the position male of the corresponding body elongated hole of this guide member is provided with one a push button;

One blade, be located in this use breach, this blade exposes to outside this use breach with part, and this guide member can make the exposed parts of this blade protrude from this body when the position that does not outwards protrude out, and can make the exposed parts of this blade protrude from that this is external when this guide member outwards protrudes out;

One elastic component is located in this body, and an end of this elastic component is located at this end fastener, and the other end is located on this guide member, is used to keep be positioned under this guide member normality this body interior and can provides this guide member to displacement back restoring force.

Though this structure has reached the purpose that prevents that accident from hurting sb.'s feelings, the structure of its design is too complicated, as needs and lead shape part and end cap portions etc., make simple inadequately, so production cost is more expensive, and it is using also underaction, the further improvement so its structure awaits.

Summary of the invention

Technical problem to be solved in the utility model provide a kind of simple in structure, make easily, but cost is low and user's cutter of autocondensation flexibly.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: but the cutter of this autocondensation, include body, blade, push pedal and spring, body is provided with chute, described push pedal drives blade can place chute slidingly back and forth, described spring is positioned at chute and the one end is fixed on the chute inwall, and its other end links to each other with push pedal, it is characterized in that described push pedal is to be placed in the strip gab of chute, and be provided with chase with respect to the chute bottom of strip gab, the two sides of push pedal are provided with wing plate, and on strip gab, be provided with the breach that can make wing plate enter chute, also be provided with the protuberance that downward extension can be passed the blade locating hole and is arranged in chase at the front end of push pedal.

Above-mentioned push pedal can be preferably strip, and its bottom has cavity, and described spring promptly is arranged in cavity, and the one end links to each other with hook portion in being arranged at the push pedal cavity, and its other end and the protruding hook that is fixed on the chase afterbody bottom surface fix.

Its leading section of above-mentioned chute can be designed to only allow blade to stretch out and narrow orifice angle shape that push pedal is skidded off.

Above-mentioned body can be embedded in the housing that is made of plastics, and body can be made by metal material, and fixed with each other by injection moulding with plastic casing.For the ease of shaking hands, its both sides of above-mentioned housing also can be provided with tread plate respectively.

Above-mentioned push pedal can be formed by plastic injection-moulded, and its surface is provided with striped anti-skidding when being used for pushing hands or matsurface.

Compared with prior art, the utility model is to be placed in the strip gab of chute because of adopting push pedal, and be provided with chase with respect to the chute bottom of strip gab, the two sides of push pedal are provided with wing plate, and on strip gab, be provided with the breach that can make wing plate enter chute, also be provided with the protuberance that downward extension can be passed the blade locating hole and is arranged in chase at the front end of push pedal.Therefore this project organization is simple, and it only has strip gab on body, and push pedal is placed in the bar opening slidably, has removed unnecessary shape part and the end cap portions led, thereby has reduced production cost; And push pedal shift length of the present utility model is big, therefore uses more flexible, more convenient; Simple and reduced unnecessary parts because of project organization again, also have the characteristics of being easy to of making naturally, the favourable dynamics of striving unexpectedly is provided for large stretch of amount production.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, present embodiment includes body 3, blade 5, housing 1, push pedal 2 and spring 4, and described housing 1 is made of plastics, and its both sides are provided with tread plate 11 respectively, see shown in Figure 1.Described body 3 is made by metal material, and is together with each other by injection moulding with plastic casing 1.Have rectangle chute 34 on body 3, the leading section 35 of this chute 34 is a narrow orifice angle shape, sees shown in Figure 2ly, only allows blade 5 to stretch out and push pedal 2 is skidded off from narrow orifice.Described push pedal 2 is for to be placed in the strip gab 31 of chute 34, and push pedal 2 also is a strip, see illustrated in figures 1 and 2, form by plastic injection-moulded, its upper surface pushing hands portion is provided with striped 22 or matsurface, when pushing hands, can play anti-skidding effect, have cavity 27 in push pedal 2 bottoms, medium position is provided with hook portion 24 in cavity 27, this hook portion 24 links to each other with spring 4 one ends that are positioned at cavity 27, and the other end of spring 4 links mutually with protruding hook 33 on being arranged on chase 32 afterbody bottom surfaces, sees shown in Figure 2.The front end two sides of push pedal 2 are provided with and are provided with wing plate 23, see Fig. 1 and shown in Figure 3, and on strip gab 31, have chute breach 26, see shown in Figure 1, described wing plate 23 promptly enters chute 34 from chute breach 26, for push pedal 2 afterbodys can stably be placed in the chute 34, the spy is provided with small wing 21 in push pedal 2 two sides of tail, sees shown in Figure 1.And the front end of push pedal 2 be positioned at two wing plates 23 below, be provided with the protuberance 25 of downward extension, see shown in Figure 3ly, the locating hole 51 of this protuberance 25 on blade 5 is set on, and slidably reciprocates at the chase 32 that is arranged in chute 34 bottoms with push pedal 2 thereby drive blade 5.

Its operating process of cutter of the present utility model is as follows:

At first be; pin the anti-skidding striped 22 of push pedal 2 with thumb; promote push pedal 2 then to front slide; the protuberance 25 that is positioned at like this on push pedal 2 bottom surfaces drives blade 5 together to front slide; because of the thickness of blade 5 very little; can from body 3 anterior 35 narrow orifice horn shapes, stretch out; and push pedal 2 is stuck in the body 3 anterior 35 narrow orifice horn shapes; thereby energy is the extension elongation of positioning blade 5 automatically; bring convenience to use, so just can use, and the time spent does not need only thumb disengaging push pedal 2; blade 5 will retract in the body 3 automatically because of the elastic force effect of spring 4, thereby plays the safeguard protection effect.
