Description
Technical field
The utility model relates to a kind of schooling apparatus, especially a kind of expanding rubber chi.
Background technology
Present Students'learning task is heavier, needs various learning tools to be used during study, and ruler and rubber are the main learning tools of people, present ruler fall short of and with rubber be what to separate, this just brings a lot of inconvenience to people in the process of use.
The utility model content
The purpose of the utility model is to provide a kind of expanding rubber chi, and this rubber chi unites two into one rubber and ruler, and the length of ruler is elongated, use, easy to carry.
The utility model solves the technical scheme that its technical problem adopted: a kind of expanding rubber chi; Comprise rubber and ruler, it is characterized in that described rubber side is provided with a groove; Described ruler is divided into multistage, is connected through rotating shaft between the two neighboring sections ruler; One end of ruler is connected in the described groove through rotating shaft.
The beneficial effect of the utility model is: rubber and ruler are combined; Be provided with the groove that can embed ruler in the described rubber, described ruler is divided into multistage, and length increases when pulling out; The use that so neither influences rubber can not influence the use of ruler yet, carries convenient.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1 rubber, 2 rulers, 3 rotating shafts, 4 grooves.
The specific embodiment
As shown in Figure 1.
A kind of expanding rubber chi comprises rubber 1 and ruler 2, and described rubber 1 side is provided with a groove 4, and described ruler 2 is divided into multistage, is connected through rotating shaft 3 between the two neighboring sections ruler 2; One end of ruler 2 is connected in the described groove 4 through rotating shaft.
In use,, just can increase the measurement length of ruler 2, the convenient use as long as ruler 2 is stretched out along rotating shaft 3; When carrying, as long as ruler 2 is embedded groove 4 along rotating shaft 3 rotary foldings, dwindled whole volume, so both be convenient for carrying and deposited the use that also can not influence rubber 1 and ruler 2.
