The utility model discloses an adjacent ruler is connected to the round pin axle, and two rulers can be folded and shorten, conveniently carry, foldable rule has multiple functions, set up the different through -hole of geometric pattern on the ruler, the geometric construction of being convenient for.

Description

Folding ruler
Technical field
The utility model relates to a kind of stationery or teaching aid, particularly one and can fold, the folding ruler be convenient for carrying.
Background technology
The chi of present use has ruler, folding ruler, set square etc., a set of ruler has multiple, not portable and easily lose, the folder function of common folding ruler just designs to reduce parking space, function singleness, although draw different angles by folding, owing to not having scale, the angle drawn is accurate not.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of folding ruler, and this folding ruler has angle measuring function, has the several functions such as ruler, protractor, set square.
The technical solution of the utility model is:
A kind of folding ruler, comprise ruler and bearing pin, it is characterized in that: described ruler comprises ruler A, ruler B and ruler C, the two ends of ruler A, B, C are equipped with the identical pin shaft hole of size, and ruler B is provided with through pin shaft hole center and is parallel to the groove A in the long sideline of ruler B; Ruler C is provided with through pin shaft hole center and is parallel to the groove B in the long sideline of ruler C; One end of one end of ruler A and ruler B links together through pin shaft hole by bearing pin; One end of the other end of ruler A and ruler C links together through pin shaft hole by bearing pin; It is fan-shaped index dial that the two ends of ruler A are provided with symmetrical shape, and index dial subscript is marked with scale mark, is provided with the scallop hole of mating with index dial below index dial, and index dial and scallop hole are all concentric with pin shaft hole.
Preferably, the long limit of described ruler A, B, C is equipped with scale.
Preferably, described ruler A is provided with the different through hole of geometric scheme.
Preferably, ruler B is not identical with the length of ruler C.
The utility model adopts bearing pin to be connected by adjacent ruler, and two rulers can folds shorten, is convenient for carrying, and solves the not portable and difficult problem that is that easily lose of multiple ruler; Folding ruler of the present utility model has angle measuring function, has the several functions such as ruler, protractor, set square; Ruler is arranged the through hole that geometric scheme is different, be convenient to geometric construction.
