Abstract
A kind of collateral line rendering ruler, including ruler are fixed with one block of side plate in ruler one end, are equipped with multiple idler wheels in side plate one end.When moving up and down ruler, frictional force can reduce using idler wheel, ruler can be moved up and down smoothly, avoid error occur when drawing parallel lines.
Description
Technical field
The present invention relates to a kind of collateral line rendering rulers.
Background technique
When present student draws parallel lines, usually using being drawn after two ruler combinations, in mobile size, by
It is larger in frictional force, therefore the ruler of pressing is easy to cause to misplace, and parallel lines is caused deviation occur.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of collateral line rendering rulers, can draw out parallel lines.
In order to solve the above-mentioned technical problem, the technical solution of the present invention is as follows: a kind of collateral line rendering ruler, including ruler,
Ruler one end is fixed with one block of side plate, is equipped with multiple idler wheels in side plate one end.
The invention has the benefit that can reduce frictional force using idler wheel, ruler can be smooth when moving up and down ruler
Move up and down, avoid draw parallel lines when there is error.
Detailed description of the invention
Following further describes the present invention with reference to the drawings:
Fig. 1 is schematic view of the front view of the invention.
Specific embodiment
A kind of collateral line rendering ruler, including ruler 1 are fixed with one block of side plate 2 in 1 one end of ruler, install in 2 one end of side plate
There are multiple idler wheels 3.When moving up and down ruler, frictional force can reduce using idler wheel 3, ruler 1 can be moved up and down smoothly, be kept away
Exempt from error occur when drawing parallel lines.
