Abstract
The invention discloses a straight scale which comprises a calibrated scale body, and is characterized in that the calibrated scale body comprises at least two sections of short scales sleeved with each other; the short scales are an accommodating short scale and an accommodated short scale; a cavity for accommodating the accommodated short scale is formed in the accommodating short scale; the short scales are connected through an anti-fall off structure; and a protrusion convenient to extend is formed at the tail end on the last section of the accommodated short scale. Compared with the prior art, the straight scale comprises the sections of short scales sleeved with each other, and the short scales can be extended and contracted, so that the stright scale is convenient to use and accomodate, and is convenient and practical.
Description
Technical field
The present invention relates to a kind of flexible be convenient to take in ruler.
Background technology
Existing ruler is a complete structure, can not shrink and stretch, ruler too in short-term, during use, range falls short of; When ruler was oversize, the accommodation space that writing case is so grown was again taken in and uses all inconvenient.
