Finalizing device for study

Abstract

The invention discloses a finalizing device for a study. The finalizing device comprises a base, a bracket and a rocking arm, wherein the rocking arm comprises rocking rods A, B, C and D which are mutually crossed in a parallelogram shape; a sliding sleeve capable of sliding up or down is arranged on each of the rocking rods A, B, C and D; a stop screw and a connecting bolt are arranged on each sliding sleeve; a sliding groove convenient for the sliding of a connecting screw is formed in each of the rocking rods A, B, C and D. Compared with the prior art, the finalizing device can replace the sudoku structure, is easy and convenient in amplification operation, can be operated by all people regardless of cultural level and ability level, can create an excellent chance of imitation learning and drawing for a beginner, is high in practicality, convenient to use and high in amplification precision, and is a new design at home and abroad.

Description

technical field [0001] The invention relates to a writing and drawing tool, in particular to a stationery finalizer. Background technique [0002] At present, painters, art lovers, and students generally have to enlarge and copy the manuscript to the required size after drawing and painting, which is costly and time-consuming. Those who do not have a copier nearby generally use Jiugongge to enlarge. This is too time-consuming, and I don’t know how many works have been missed and how many opportunities for copying and learning have been lost. The magnifying ruler in the prior art (such as the dove ball standard magnifying ruler) does not have satisfactory magnifying effect: the first, it enlarges and is exactly twice, if a piece of traditional Chinese painting on three feet is amplified on a four-foot paper , it can’t be completed at all, the reason is that its reading area is small, unless the three-foot paper is cut into three small pieces, it can be read. The enlarged pic...

[0002] At present, painters, art lovers, and students generally have to enlarge and copy the manuscript to the required size after drawing and painting, which is costly and time-consuming. Those who do not have a copier nearby generally use Jiugongge to enlarge. This is too time-consuming, I don’t know how many works have been missed and how many opportunities for copying and learning have been lost

The magnifying ruler in the prior art (such as the dove ball standard magnifying ruler) does not have satisfactory magnifying effect: the first, it enlarges and is exactly twice, if a piece of traditional Chinese painting on three feet is amplified on a four-foot paper , it can’t be completed at all, the reason is that its reading area is small, unless the three-foot paper is cut into three small pieces, it can be read. The enlarged picture is at least 2 meters long, and the four-foot paper cannot fit. The use value is completely lost; second, the area of ​​the picture enlarged by a single sheet is very small, the largest is only 0.72m 2 ;Third, its Achilles' heel is that the magnification is very inaccurate, it cannot be used at all, and its practicability is poor. There has never been a similar design at home and abroad. not free to control
