Abstract
The utility model discloses a paper knife, including fixing base, blade bearing, blade, pulley, axis of rotation and adjust knob, be equipped with the pulley groove on the fixing base, to install in the pulley groove pulley slidable, the one end of blade bearing is connected with the pulley through the axis of rotation, and the other end is connected with adjust knob, and the blade passes through adjust knob and installs on the blade bearing. This paper knife can follow the straight line and cut out and can measure and cut out length, lets blade and ruler separate simultaneously, and the use is got up safelyr.
Description
Technical field
The utility model relates to a kind of paper knife, especially can linearly cutting can measure the paper knife of cutting length.
Background technology
In order to cut out the scraps of paper of linear edge, traditional method is to use blades fit ruler, pins ruler with a hand, and another receipts are held alignment blade ruler edge and cut, and this mode easily allows blade hurt hand or scratch ruler.
The Chinese invention of Application No. 201210265874.0 discloses a kind of safe paper cutters, it is characterized in that base, handle and sheath surround one and close right angled triangle, it is effectively guaranteed the safety of user, but this design can not well realize the cutting of length-specific straight line.
The Chinese invention of Application No. 201310590032.7 discloses a kind of paper knife, and this paper knife can be cut a sheet of paper with straight line and will not cut out askew, it is possible to the size of control cutting paper, but its complicated structure.
Summary of the invention
Existing paper knife can not realize linearly cutting or blade easily hurts hand or scratches ruler, in order to make paper knife can linearly cutting cutting length can be measured, the utility model provides a kind of simple in construction, the paper knife of safe ready.
The utility model solves its technical problem and be the technical scheme is that a kind of paper knife, including fixing seat, blade bearing, blade, pulley, rotary shaft and adjusting knob, it is characterized in that: fixing seat is provided with pulley groove, pulley is slidably mounted in pulley groove, one end of blade bearing is connected with pulley by rotary shaft, the other end is connected with adjusting knob, and blade is arranged on blade bearing by adjusting knob.
Pulley groove is T font, and fixing seat is additionally provided with scale, and scale is metric system or English system.
One end of blade bearing is provided with shaft hole, and shaft hole is connected with pulley rotation by rotary shaft.The centre of blade bearing is provided with insert groove, and insert groove has the through screwed hole to the blade bearing other end, adjusting knob is provided with threaded post, blade bearing and adjusting knob and is rotationally connected by screwed hole and threaded post.Blade is removably mounted on insert groove by adjusting knob.
The beneficial effect of the invention is: make paper knife can linearly cutting cutting length can be measured, allow blade separate with ruler simultaneously, use safer.

Fig. 1 is the overall structure schematic diagram of a kind of paper knife；
Fig. 2 is the fixed seat structure schematic diagram of a kind of paper knife；
Fig. 3 is blade and the blade bearing portion structure schematic diagram of a kind of paper knife；
In figure: fixing seat 1, blade bearing 2, blade 3, pulley 4, rotary shaft 5, adjusting knob 6, pulley groove 11, scale 12, shaft hole 21, insert groove 22, screwed hole 23, pulley hole 41, threaded post 61.
Detailed description of the invention
For making the utility model purpose, technical scheme clearer, the utility model is described in further detail for specific embodiment below in conjunction with the accompanying drawings.
Seeing shown in accompanying drawing 1-3, paper knife includes that fixing seat 1, blade bearing 2, blade 3, pulley 4, rotary shaft 5 and adjusting knob 6, fixing seat 1 are provided with pulley groove 11 and scale 12, and pulley groove 11 is in T font, and scale 12 is metric system or English system.Pulley 4 is slidably mounted in pulley groove 11, and one end of blade bearing 2 is provided with shaft hole 21, and shaft hole 21 is rotationally connected with pulley 4 by rotary shaft 5.The centre of blade bearing 2 is provided with insert groove 22, there is on insert groove 22 the through screwed hole 23 to blade bearing 2 other end, threaded post 61 it is provided with on adjusting knob 6, blade bearing 2 and adjusting knob 6 are rotationally connected by screwed hole 23 and threaded post 6, and blade 3 is removably mounted on insert groove 22 by adjusting knob 6.
Unclamping adjusting knob 6, blade 3 is put into insert groove 22, then tightens adjusting knob 6, blade 3 can be fixed on blade bearing 2.When dragging blade 3, blade bearing 2 can be driven to move, by rotary shaft 5 band movable pulley 4, the motion of pulley 4 is limited in pulley groove 11, the movement locus making blade 3 is always maintained at parallel with fixing seat 1, the most just make paper knife can linearly cutting, fixing seat 1 is provided with scale 12, the paper of length-specific can be cut out.
Owing to blade bearing 2, pulley 4 are all by being rotationally connected with the connection of rotary shaft 5, so blade 3 can easily be adjusted to suitable angle and carry out cutting；And owing to have employed blade 3 and the fixing separate design of seat 1, paper knife linearly cutting can not only be realized, also can prevent blade 3 from hurting hand or scratching ruler, use safer.
The foregoing is only detailed description of the invention of the present utility model; but protection domain of the present utility model is not limited thereto; any those familiar with the art is in the technical scope that the utility model discloses; change can be readily occurred in or replace, all should contain within protection domain of the present utility model.
