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 which comprises a shell, a tape measuring mechanism and a buffer mechanism; the tape mechanism comprises a first measuring tape and a second measuringtape; and a line drawing pen is arranged on the second measuring tape. The steel tape not only has a measuring function, but also has line drawing and marking functions, is convenient to carry and use, and improves the working efficiency. Besides, the steel tape is provided with the buffer mechanism, so that when the tape mechanism retracts a tape, the retraction speed of the tape can be slowed down, and an internal structure is prevented from damaging 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.
