Abstract

The invention discloses an art knife. The art knife comprises a case and a blade arranged in the case in a sliding mode. The blade is provided with a cutting line and can extend out or retract from the end, at the head portion of the blade, of the case in the longitudinal direction of the case. A sheath where the blade passes is arranged at the end, at the head portion of the blade, of the case. The art knife is simple in structure and low in cost, and the blade of the art knife can be easily and safety broken off with hands.

Description

Cutter

Technical field

The present invention relates to cutter, particularly cutter.

Background technology

Current normally used cutter, comprise housing, blade and blade adjustment piece, during use, normally the cutter head end of blade is stretched out to the end of housing, utilize the blade tip of blade and near blade blade tip to cut, after the blade tip passivation of blade, the cutting effect of cutter has just reduced, the joint at this time having needed blade passivation breaks, just can use new sharp blade tip, but blade cannot directly be broken disconnected by a joint of passivation, must be by means of instrument, such as pliers, or spanner, cumbersome during use, when the width of pliers or spanner is less than the width of blade, also easily occur breaking, the fragment that causes blade disorderly flies and hurts user or other people, very dangerous, if after blade tip passivation, directly whole blade is thrown aside, waste again blade, uneconomical.

Summary of the invention

Technical problem to be solved by this invention is: in order to solve the problems of the technologies described above, provide a kind of simple in structure, with low cost, cutter of breaking breaking sheet that can be light and safe.

For solving the problems of the technologies described above, the technical solution adopted in the present invention is: cutter, comprise housing and slide and be arranged at the blade in housing, on described blade, be provided with line of weakness, described blade can prolong one end that is longitudinally positioned at blade head from housing of housing and stretches out or retract, and one end that described housing is positioned at blade head is also provided with the sheath that can supply blade pass;

Described sheath is met to the angle of the end face of housing and line of weakness formation and is less than 5 degree;

Described housing is positioned at one end end face of blade head and the angle of line of weakness formation is less than 5 degree;

Described housing is positioned at and on one end end face of blade head, is provided with the hinge that sheath and housing are linked together, and the rotary middle spindle of described hinge is parallel to blade and is less than 5 degree with the angle that line of weakness forms;

Described hinge is arranged on housing back to the one side of line of weakness;

Described hinge is film hinge;

Described sheath is provided with the fixture block stretching out to housing in the one side of hinge, is provided with and the friction tight draw-in groove of fixture block on described housing;

Described blade end is connected with slidable adjustment piece, and described slidable adjustment piece can promote blade and prolong housing longitudinal sliding motion, and the end of described housing is also provided with end cap.

The invention has the beneficial effects as follows: on cutter, carry sheath, can directly use sheath to clamp blade, blade is broken disconnected, in addition, the blade part being clamped in sheath can not splash everywhere yet, has guaranteed the safety in breaking blade process, and the making of this cutter is also fairly simple.

The specific embodiment

Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.

Be illustrated in figure 1 cutter of the present invention, comprise housing 1 and slide and be arranged at the blade 2 in housing 1, on described blade 2, be provided with line of weakness 4, described blade 2 can prolong one end that is longitudinally positioned at blade 2 heads from housing 1 of housing 1 and stretches out or retract, and one end that described housing 1 is positioned at blade 2 heads is also provided with the sheath 5 that can supply blade 2 pass.

Be provided with the cutter of sheath 5, after the blade tip passivation of blade 2, can directly blade 2 need to be broken to disconnected part and be placed in sheath 5, then just can the hand-held sheath 5 of a hand-held housing 1,, firmly blade 2 is broken disconnected.

From Fig. 1, can find out, described sheath 5 is met to the angle of the end face of housing 1 and line of weakness 4 formation and is less than 5 degree; Described housing 1 is positioned at one end end face of blade 2 heads and the angle of line of weakness 4 formation is less than 5 degree.Can better control the folding line of blade 2 like this, blade 2 is disconnected along line of weakness 4.

Described housing 1 is positioned at and on one end end face of blade 2 heads, is provided with the hinge that sheath 5 and housing 1 are linked together, and the rotary middle spindle of described hinge is parallel to blade 2 and is less than 5 degree with the angle that line of weakness 4 forms, can guarantee that like this sheath 5 prolongs the vertical direction rotation of line of weakness 4, make to break breaking sheet and seem lighter, but also sheath 5 and housing 1 can be coupled together, prevent the loss of sheath 5.

As shown in Figure 2, described hinge is arranged on housing 1 back to the one side of line of weakness 4, i.e. the back side of housing 1, and described hinge is film hinge 6, this simple in structure, cost is low.

Described sheath 5 is provided with back to the one side (front of housing 1 as shown in Figure 1) of hinge the fixture block 52 stretching out to housing 1, on described housing 1, be provided with and the friction tight draw-in groove 11 of fixture block 52, compact being fastened in draw-in groove 11 of fixture block 52 that tight fit makes, in normal use cutter, sheath 5 is as on being fixedly connected on housing 1, can not cause harmful effect to the use of cutter, and when needs are broken breaking sheet 2, the power perpendicular to line of weakness 4 that sheath 5 is applied, can be relatively easy to again fixture block 52 is spun off in draw-in groove 11.

Described blade 2 ends are connected with slidable adjustment piece 3, and described slidable adjustment piece 3 can promote blade 2 and prolong housing 1 longitudinal sliding motion; The end of described housing is also provided with end cap 7.

The course of work of the present invention is: in conjunction with Fig. 1 and Fig. 2, in the use procedure of cutter, passivation at first be foremost one section of blade 2, when blade 2 need to be broken the part of disconnected its passivation, promote slidable adjustment piece 3, the position of adjustable blade in housing 1, the part of passivation is stretched in sheath 5, now one hold housing 1, pinch sheath 5 on the other hand and make the back side rotation of sheath 5 along film hinge 6 to housing 1, the stressed disengaging draw-in groove 11 of fixture block 52, continue rotation sheath 5 until the part of blade 2 passivation stops while fractureing, the passivation part of breaking the blade 2 of having no progeny skids off in sheath 5, subsequently sheath 5 is rotated back to original position, fixture block 52 is snapped in draw-in groove 11, again promote slidable adjustment piece 3, the position of adjustable blade 2 in housing 1, and cutter is used in continuation.Whole operating process is safety simply again.
