Abstract

The invention discloses a damping clamping block positioning type drawing child-mother ruler. The damping clamping block positioning type drawing child-mother ruler comprises a mother ruler and a child ruler, wherein the mother ruler and the child ruler are both T-shaped rulers; a clamping block is installed at the tail end of the mother ruler; a clamping groove is formed in the inner part of theclamping block; the clamping block is fixed to the outer part of the mother ruler through the clamping groove; a damping adjusting button is installed at the end, close to a damping spring, of the outer part of an outer shell; a sliding groove is formed in the middle part of the outer shell; a shortcut moving button is fixed into the sliding groove; one end of the shortcut moving button is fixed to the damping spring; and the other end of the shortcut moving button is fixed to the outer surface of the outer shell. According to the technical scheme of the damping clamping block positioning typedrawing child-mother ruler, any point on the drawing can be covered, by arranging the damping clamping block, the fixing and loosening are convenient, the shaking can be avoided effectively, the drawing is more accurate, the composition is simple, both of the ruler and the damping clamping block can be carried separately, and the cost is low.

Description

technical field [0001] The present disclosure generally relates to a master ruler, and in particular to a drawing master ruler of a damping block positioning type. Background technique [0002] In the past, the traditional T-square drawing must be equipped with a triangular plate and needs to be constantly changed and rotated, and the T-square is easy to shake when making long lines, which brings great errors to the drawing. The special drawing board sold on the market, in addition to must In addition to using the special supporting drawing board produced by them, it is not equipped with clamping blocks to reduce shaking, and the price is very expensive. Contents of the invention [0003] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a damping block positioning type drawing master, which can effectively avoid shaking and make drawing more accurate. [0004] first, [0005] According to the technical solution provided by...
