Problems solved by technology

At present, the steel tape is widely used in the measurement of woodworking, decoration, cutting and other fields. After measuring the length, it is necessary to use ink fountain, ruler and other line drawing tools to draw a line between two points. The steel tape and line drawing tool Changing back and forth is not only inconvenient to carry, but also troublesome to use, which affects work efficiency
In addition, after the existing steel tape is pulled out, the tape retracts too fast, which not only easily leads to damage to the internal structure of the steel tape, but also easily scratches the fingers

Abstract

The invention discloses a line-drawing steel tape measure, which comprises a casing, a tape measure mechanism and a buffer mechanism, wherein the tape measure mechanism includes a first tape measure and a second tape measure, and a line-drawing pen is arranged on the second tape measure. In addition to the measurement function, the steel tape measure of the present invention also has the functions of drawing lines and marking, is convenient to carry and use, and improves work efficiency. In addition, the present invention is equipped with a buffer mechanism, which can slow down the retraction speed of the tape when the tape mechanism winds up the tape, preventing damage to the internal structure and scratching fingers.

Description

technical field [0001] The invention belongs to the technical field of surveying and mapping tools, in particular to a line-drawing steel tape measure. Background technique [0002] Steel tape measure is a commonly used measuring tool in life, and it is one of the necessary tools in the family. It can complete the measurement of the size and distance of long objects. At present, the steel tape is widely used in the measurement of woodworking, decoration, cutting and other fields. After measuring the length, it is necessary to use ink fountain, ruler and other line drawing tools to draw a line between two points. The steel tape and line drawing tool Changing back and forth is not only inconvenient to carry, but also troublesome to use, which affects work efficiency. In addition, after the existing steel tape is pulled out, the tape retracts too quickly, which not only easily causes damage to the internal structure of the steel tape, but also easily scratches fingers.
