Description
Technical field
This utility model is related to stationery, particularly to a kind of paper knife.
Background technology
The paper knife in a manual manner paper being cut at present, generally includes base plate, pressing plate, scale and cutting knife；Cut out
Cut paper during operation to be laid on base plate, pressing plate is resisted against on base plate, paper is clamped between pressing plate and base plate so that paper
It is not susceptible to displacement, improve the success rate cutting；It is connected using rotating shaft between pressing plate and base plate, take out press plate rotary during paper
Dig, pressing plate is separated with paper, thus paper is taken out；Guiding seam and guide channel are additionally provided with pressing plate, cutting knife embeds guiding
Meet with guide channel in, point of a knife partially pass through guiding seam extend on base plate, cutting knife guiding seam and guide channel constraint under use knife
Paper on base plate is cut off by point；Scale includes horizontal scale, longitudinal scale and guiding ruler, and guiding ruler is arranged generally along the longitudinal direction, with horizontal stroke
Perpendicular to scale, guiding ruler is provided with graduation mark so that guiding ruler extends constitutes longitudinal scale, and such paper is in longitudinal and transverse two sides
There is clear and definite positioning upwards, be easy to determine the position cutting；Because base plate is generally positioned at desktop, for the ease of putting, bottom
The longitudinal size of plate is less so that the length of longitudinal scale cannot tackle longer paper cutting requires, therefore generally in guiding ruler
Lower end setting extension, between extension and base plate rotate be connected, the lower wall of base plate is provided with caulking groove, is not using
During extension, extension rotates embedded caulking groove so that base plate is clean and tidy.
The shortcoming of prior art is：Extension does not have the edge of projection, rotates after launching to dock with longitudinal scale, though
So the length of longitudinal scale is extended, and the paper at extension position lacks against so that the precision of paper longitudinal register is difficult to
Ensure, the precision cutting is affected；Secondly, the surface of extension is less than backplate surface it is impossible to longitudinal scale at one
Dock in plane, affect longitudinal register precision；In addition, the base plate of extension is not also concordant with desktop so that extension lacks
Few bottom supports, and is susceptible to bend, affects positioning precision further, also reduce the performance of operation.
The information being disclosed in this background section is merely intended to increase the understanding to general background of the present utility model, and
It is not construed as recognizing or imply in any form that this information structure has been existing well known to persons skilled in the art
Technology.
Utility model content
The purpose of this utility model is to provide a kind of paper knife, the extension concordant with backplate surface is set so that

Constitute longitudinal scale；Wherein, the lower end in guiding ruler arranges extension, rotates and be connected between extension and base plate, extends
The upper surface of scale is concordant with the upper surface of base plate, and the lower surface of extension extends support lugn, support lugn and base plate
Bottom supporting surface flush so that extension turn on dock with longitudinal scale when bottom by secure support it is ensured that prolonging
Stretch reliability and the precision of scale；When not using extension, extension is rotated and is offseted with the lower section side surface of base plate
By so that base plate keeps clean and tidy.
In technique scheme, it is further preferred that the edge of described extension is provided with projection, thus constituting extension
Guiding ruler, extension extend guiding ruler and guiding ruler flush when turning on and dock with longitudinal scale it is ensured that paper against precision, prolong
The surface stretching guiding ruler is provided with extension graduation mark.
The thickness of described extension is less than base plate thickness, and the non-side surface bottom leaning with base plate extends composition institute
The support lugn stated, base plate extends groove along longitudinal scale direction towards at the lower section side surface against scale, forms base plate
Stairstepping at the side surface of lower section for the upper surface, the depth of groove is consistent with the thickness of extension, the width of groove with
The width of extension matches so that can embed in groove when extension is packed up, the surface of extension and base plate
Upper surface is concordant, and being easy to paper when extension is packed up can open and flat be placed on；Although when extending guiding ruler expansion, base plate
The edge of upper surface stairstepping occurs, but the width extending guiding ruler is less, open and flat on paper places impact very little.
Compared with prior art, this utility model passes through the extension of setting and plate upper surface flush, and extends
The bottom of scale obtains the support concordant with base plate, extend the upper surface of guiding ruler and base plate simultaneously to sheet support so that increasing
Plus while paper longitudinal register, improve the performance laying paper, the positioning precision of paper is strengthened；By on scale
What setting was raised extends guiding ruler so that paper positioning in the vertical is guaranteed；By setting extension in backplate surface setting
The groove of scale, so that when extension is packed up, the surface of extension is concordant with the upper surface of base plate, is meeting longitudinal scale
While extension needs, also when extension is packed up, good supporting role can be played to the tiling of paper.
