Description

A kind of Drawing instrument for copying other drawings

Technical field the utility model relates to a kind of Drawing instrument for copying other drawings, more particularly, relates to a kind of boxlike Drawing instrument for copying other drawings that utilizes light reflection principle.

Background technology in the prior art, do not find desirable Drawing instrument for copying other drawings as yet, especially do not find to utilize the Drawing instrument for copying other drawings of light reflection principle, ZL01212003.0 disclosed " Drawing instrument for copying other drawings " is by copying the Drawing instrument for copying other drawings that rope sling and drawing pencil are formed, be not to utilize optical principle, and be and the diverse product of the utility model.

It is a kind of simple in structure, easy to use and utilize the boxlike Drawing instrument for copying other drawings of light reflection principle that the summary of the invention the purpose of this utility model is to provide.

In order to achieve the above object, the utility model provides following technical scheme: design a kind of Drawing instrument for copying other drawings, be boxlike, comprise identical upper casing of structure (1) and lower casing (2), upper casing (1) and lower casing (2) are hinged, fillet at upper casing (1) and lower casing (2) has at least two collars (3) that fuse with them respectively, the hinge portion of this plotter has the rotating shaft (4) that two identical cross sections have U-shaped slot (5), one end of rotating shaft (4) has cavity, two rotating shafts (4) are enclosed within the joint (6) that adapts with it and upward realize being connected, the collar (3), rotating shaft (4) is positioned on the straight line with joint (6) and passes separately by a steel wire that centre bore (10) links to each other, have the slot (8) with angle on the joint (6), two transparent reflecting plates (9) are inserted in U-shaped slot (5) simultaneously by its following extending area respectively, in the slot (8) and form certain included angle.In the use, the paper that will have literal or a pattern is placed on wherein on the transparent reflecting plate (9), promptly be positioned at the transparent reflecting plate (9) between two transparent reflecting plates (9), the paper of copying usefulness is lain in the shell that faces mutually with the transparent reflecting plate of another piece (9), eyes are being seen the top of the transparent reflecting plate of another piece (9), can face rubs draws a picture, quite convenient.Because the thickness of the more transparent reflecting plate of width (9) of the notch of U-shaped slot (5) is wide, add that two rotating shafts (4) are enclosed within on the joint (6), slot (8) is also arranged on the joint (6), transparent reflecting plate (9) just is the activity attitude, suitably adjusting angle adapts to people's adjusting angle that different drawing are accustomed to.

The utility model technical scheme preferably is:: the folding limit of upper casing (1) and lower casing (2) has hasp (7) respectively, and two hasps (7) are preferably in the back of closing and stagger on the folding limit.When time spent not, upper casing that closes (1) and lower casing (2), hasp (7) are close to and are closed the limit, help it is closed up and are difficult for opening easily, are convenient to protect the transparent reflecting plate (9) in it.

Compared with prior art, the utlity model has simple in structure, easy to use, advantage such as be easy to carry, the people that the people who extensively is suitable for various ages especially begins to learn drawing or calligraphy uses.
