Abstract
The invention discloses an integrated circular paper cutter which comprises a compasses, wherein the compasses is provided with a left pin and right pin, the lower end of the right end is in pin joint with a cutter wheel, and the edge of the cutter wheel is provided with cutter teeth. After the optimization, the cutter teeth are evenly distributed along the edge of the cutter wheel; the lower end of the left pin is in hinge joint with a suction cup; and the suction cup is made from the rubber material. The integrated circular paper cutter has the advantages that the formed circular paper piece is higher in accuracy; and the interior of the paper piece is free of any holes, so that the paper piece is more integrated.
Description
Technical field
The present invention relates to the stationery technical field, especially relate to a kind of complete circle paper-cutter.
Background technology
At present, when cutting circular paper,, utilize scissors to get final product by hand afterwards along the track cutting how through the compasses circular trace of on paper, drawing.Its defective is: 1, the hand cutting accuracy is relatively poor.2, circular paper central authorities leave the pin hole that the bow compass positioning pin pin forms, and the scraps of paper are not sufficiently complete.Therefore be necessary to improve.
Summary of the invention
Deficiency to above-mentioned prior art exists the purpose of this invention is to provide a kind of complete circle paper-cutter, and it is higher that it has formed circular paper accuracy, and the inner no any hole of the scraps of paper, thus comparatively complete characteristics.
To achieve these goals, the technical scheme that the present invention adopted is: the complete circle paper-cutter, comprise compasses, and these compasses are provided with left foot and right crus of diaphragm, and said right crus of diaphragm lower ending pivot is connected to break bar, and this break bar edge is provided with cutter tooth.
Said cutter tooth evenly distributes along the edge of break bar.
Said left foot lower end is hinged with sucker.
Said sucker is the sucker of elastomeric material preparation.
After adopting said structure, the present invention compares the advantage that is had with prior art and is: 1, formed circular paper accuracy is higher.The right crus of diaphragm of complete circle paper-cutter of the present invention is provided with break bar, and the circumference of break bar is densely covered with cutter tooth.Like this, after the right crus of diaphragm rotation, cutter tooth forms whole rounded some circular perforation on paper, and the cutter can easily and tear out circular paper accurately along these perforations.2, the inner no any hole of the scraps of paper is comparatively complete.The left foot of compasses is fixed on the paper through sucker, need not to use the location stitch, thereby can not keep the complete of circular paper at the inner pin hole that forms of circular paper.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified:
Fig. 1 is the front view (broken section) of embodiments of the invention;
Fig. 2 is that the A of Fig. 1 of having amplified is to view;
Fig. 3 is the B portion enlarged drawing of Fig. 1.
Among the figure: 10, compasses, 11, left foot, 12, right crus of diaphragm; 20, sucker; 30, break bar, 31, cutter tooth.
The specific embodiment
The following stated is merely preferred embodiment of the present invention, does not therefore limit protection scope of the present invention.
Embodiment, see that Fig. 1 is to shown in Figure 3: the complete circle paper-cutter, comprise compasses 10, these compasses 10 are provided with left foot 11 and right crus of diaphragm 12.This sentences left foot 11 and describes for angle.Wherein, right crus of diaphragm 12 lower ending pivots are connected to break bar 30, and these break bar 30 edges are provided with cutter tooth 31.Obviously, the central axis of break bar 30 and pivot overlap, and this central axis along continuous straight runs intersects at left foot 11.Like this, after right crus of diaphragm 12 rotations, break bar 30 rolls on paper, forms some compact arranged perforations, and these perforation integral body are rounded, and the user only needs gently to tear along these perforations, can paper be torn into circular paper accurately.
Optimize, cutter tooth 31 evenly distributes along the edge of break bar 30.Obviously, be beneficial to the accuracy to size of the further raising circular paper that forms like this.
Further, left foot 11 lower ends are hinged with sucker 20.Obviously, sucker 20 is inhaled on paper, as the angle of compasses 10.Like this, avoid occurring using when locating stitch in the inner phenomenon that forms pin hole of circular paper.Continue to optimize, this sucker 20 can be taked the elastomeric material preparation.Like this, the suction of sucker 20 is stronger, and is convenient to the preparation of sucker 20.
