Embodiment Construction
[0064] A drawing ruler device provided by the present invention will be described in detail with reference to the accompanying drawings in the embodiments of the present invention.
[0065] As a further improved technical solution of the present invention, see figure 1 :
[0066] The distance between the end of the score component and the protruding component can be adjusted, and this design can improve the depth of the score printed by the score component on the graphic plane;
[0067] Further, the design in which the distance between the end of the scoring component and the protruding component can be adjusted can realize the printing of scores on the graphic plane of various materials by means of reciprocating and lifting the scoring component on the protruding component with high frequency. It solves the problem of scraping damage to the graphic plane itself when drawing on a softer graphic plane, thereby improving the scope of application of the device;
[0068] Further...
