The utility model relates to a kind of sanction that supplies and cuts the Cutter that flexible material is used.

At present in daily life, for chemical fibre carpet, embroidered carpet with glue coating back, PVC flooring laminate, wallpaper, leather, hair, the sanction of flexible material such as chemical ﹠ blended fabric cuts.Traditional manual method is that the sanction secant has been drawn by the elder generation that has, and cuts along cutting out the secant sanction with cut-off knife or scissors again; What also have is equipped with bed course in cut the thing below by sanction, selects for use suitable ruler (bar) as guide rail, firmly cuts out with cut-off knife along the one side and cuts.The weak point of these methods is: rabbet not merit is whole, has piece when closing up again; Operation is wasted time and energy and is wasted bed course; Operation is dangerous, is easy to the injury person.

The purpose of this utility model is that a kind of improved Cutter will be provided, and it can improve the sanction of cut-off knife effectively and cut function, improves rabbet quality and operational security.

The purpose of this utility model is achieved in that the blade that knife rest crouches and adorns a two-sided blade and be shaped on the slotted hole that supplies the adjustment self-position.One end of knife rest is provided with retouches accurate limit, retouch be shaped on the extended line direction of accurate limit and with a silk hole, hold the groove of blade, collet is shaped on the bar groove of shovel head and blade movement track below and upper side a little more than retouching accurate limit, also is shaped on knife-edge waist and lever on the knife rest.

The advantage of utility model: the straight merit of rabbet is whole, does not deposit piece when closing up again; Operation is time saving and energy saving, and is safe and efficient; Simple in structure, easy to carry, cheap for manufacturing cost.

Description of drawings:

Fig. 1 is a kind of Cutter front view;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is I-I cutaway view of Fig. 1.

Below in conjunction with details and the working condition of Fig. 1-3 detailed description according to the concrete device that the utility model proposes.

This device is included in blade 8 formations that crouch and adorn a two-sided blade and be shaped on the slotted hole that supplies the adjustment self-position with screw 9 on the knife rest 1.

Said knife rest is selected for use rigid plastics or light metal material to cast integral body to be set square shape substantially, and its front end is provided with the straight accurate limit (being that the cross section is tip-angled shape) 2 of retouching of convergent.On the extended line direction of retouching accurate limit, be shaped on the groove that holds blade that turns forward and have a silk hole, the bottom land back side is shaped on the boss that surrounds the silk hole.Be shaped on collet 5 with the knife rest vertical direction.Upper and lower two sides of collet are basically parallel to retouches accurate limit, and upper side is a little more than retouching accurate limit, and the leading section of collet is that duck chews formula shovel 3, and is shaped on below the blade movement track for the bar groove 4 that holds blade.The waist of knife rest is shaped on the opening that comprises the part blade groove, and sweptback knife-edge waist 6 is made in the position on that limit that is positioned at the blade rear of opening.The both sides, hypotenuse top of knife rest respectively are shaped on the lever 7 of plough groove type.

Working condition is such, cut line earlier on the material by sanction, with the alignment line of the accurate limit of retouching of this device knife rest, starts the shovel head that collet is being pressed on the material limit, and the end of ruling is aimed at blade cutting edge.A hand is caught the material limit, and another lever of holding knife rest promotes forward, remains in the motion process that to retouch accurate limit consistent with line, severs until material is cut out.By two rabbets being cut apart with a knife or scissors, through the waist 6 of knife rest separately, and slightly lift in the motion process, can reduce and exert oneself along the upper side of collet.When the blade of feeling blade is not sharp, can unclamp screw 9, vertically adjust blade position, make the sharp position of blade place the operating position.Or the working edge of replacing blade, being about to 180 ° of the vertical or horizontal upsets of blade original position, adjustment finishes, and screws screw.
