Abstract

The invention provides a length stamp which is characterized in that the length stamp integrates the functions of a tape and a seal; a four-digit code wheel is added to the side of a tape shell; and when a tape band stretches out, the seal is driven to act, the digits are adjusted automatically to the current length of the outstretched part of the tape band, and the operation is completed after the digits are stamped on paper or a hand. The length stamp has the following beneficial effects: the length stamp is simple in design; by integrating a tape and a seal, the measured size can be recorded easily; and the length stamp is easy to use and reasonable in structure.

Description

technical field [0001] The invention relates to a measuring instrument, in particular to a seal tape measure. Background technique [0002] As early as the Ming Dynasty, Cheng Dawei, a famous Chinese mathematician, abacus operator and inventor, invented the world's first tape measure "measuring step car". Carry and use. Tape measures often need to be used together with other tools, and tape measures with a single function on the market often cannot meet the increasing needs of consumers. Contents of the invention [0003] The invention provides a seal tape measure. [0004] The technical solution adopted by the present invention is: it integrates the two functions of the tape measure and the seal, and adds a four-digit digital wheel on the side of the tape measure shell. When the tape stretches out, it will drive the seal to move, and the number will be automatically adjusted. It is the length that is currently protruding, and then, put it on the paper and cover it with...
