Abstract

The utility model relates to a cutter, in particular to a safe paper cutter which comprises a knife rest provided with a T-shaped through, a fixing iron sheet, a blade and a V-shaped support, wherein the blade is arranged in the T-shaped through of the knife rest and connected with the fixing iron sheet; the right side of the V-shaped support and the top end of the knife rest with the T-shaped through are welded together to form a 4 shape. A knifepoint of the blade can expose only when a tool shank is pressed slightly, so hands cannot be hurt; in addition, the contact area between the V-shaped support and a paper is enlarged, so the paper cannot swing left and right in cutting, thereby the utility model enhances the cutting precision and has the advantages of simple, safe and convenient use, precise cutting, and the like.

Description

Safety limit paper cutter

[technical field]

The utility model relates to a kind of cutting tool, particularly a kind of safety limit paper cutter.

[background technology]

Our cutting tool has scissors, boundary's paper cutter etc. at present.We often will use boundary's paper cutter and come boundary's paper, boundary's blowing paper when doing the wall newspaper propaganda; Each use must be released blade, with after again the blade withdrawal is gone, as easy as rolling off a logly on the table hand circle can be hindered because of carelessness otherwise put.General boundary is to spur near the chi edge with boundary's point of a knife during paper, and contact area is very little, grasps bad appearance circle and draws the chi face, injures finger; Leave the chi limit sometimes and cause the not enough straight line of Kai Jie trimming edge, even cancel, so present boundary's paper cutter uses shortcomings such as trouble, degree of safety is low, the cutting degree of accuracy is low.

[summary of the invention]

The purpose of this utility model provides safe ready, accurate, the simple a kind of safety limit of the use paper cutter of cutting.

A kind of safety limit paper cutter, comprise knife rest (3), fixed iron piece (5) and a blade (6) that is provided with "T"-shaped groove, comprise in addition: the support (2) of one " V " shape, wherein, blade (6) places in the "T"-shaped groove of knife rest (3) and with fixed iron piece (5) and is connected, the top of the right of the support (2) of " V " shape and the knife rest (3) of "T"-shaped groove welds, and forms " 4 " font.

Tail end is connected in the "T"-shaped groove of described fixed iron piece (5) and knife rest (3).

Described anti-skidding striped taper knob (4) and knife rest (3) outside are complementary.

Two iron plate folders of the left side welding of the support of described " V " shape.

The aligning point of a knife place of described " V " shape support establishes a groove.

Technique effect of the present utility model is:

A kind of safety limit paper cutter comprises knife rest, a blade that is provided with "T"-shaped groove, also comprises the support of one " V " shape, need hold taper knob slightly firmly toward pressing down, the point of a knife of blade just reveals and can't get out, so can not hinder hand, adds that the support of " V " shape and the contact-making surface of paper enlarge, can not swing during cutting, improved the cutting degree of accuracy, in addition, the slide bar of a band scale can be installed on two iron plate folders, regulate this radius distance, very conveniently go out a circle in the paper upper bound and come.

[description of drawings]

Fig. 1 is the structural representation of utility model safety limit paper cutter.

Among the figure: 1 iron plate folder, the support of 2 " V " shape, the knife rest of 3 "T"-shaped grooves, the taper knob of 4 anti-skidding stripeds, 5 fixed iron pieces, 6 blades.

[specific embodiment]

The CONSTRUCTED SPECIFICATION of utility model embodiment is described in detail in detail below in conjunction with accompanying drawing:

A kind of safety limit paper cutter, comprise knife rest (3), fixed iron piece (5) and a blade (6) that is provided with "T"-shaped groove, comprise in addition: the support (2) of one " V " shape, wherein, blade (6) places in the "T"-shaped groove of knife rest (3) and with fixed iron piece (5) and is connected, the top of the right of the support (2) of " V " shape and the knife rest (3) of "T"-shaped groove welds, and forms " 4 " font.Grasp the taper knob 4 of the anti-skidding striped on the knife rest 3 of "T"-shaped groove, firmly toward pressing down, the tip of blade 6 is forced out, but along circle, chi limit paper, when loosing one's grip, the tip withdrawal of blade 6, can reach and prevent from hand circle to be hindered because of carelessness, and the support 2 of " V " shape enlarges with the contact-making surface of paper, can not swing during cutting, has improved the cutting degree of accuracy, in addition, the slide bar of one band scale can be installed on two iron plates folder 1, regulate this radius distance, very conveniently go out a circle in the paper upper bound.
