Abstract
The utility model relates to a novel mathematic multi-purpose ruler. The novel mathematic multi-purpose ruler comprises a fixed ruler and a movable ruler, and is characterized in that: the fixed ruler and the movable ruler are provided with central lines respectively; the left end of the fixed ruler is fixed to a protractor; the left end of the fixed ruler is connected with the left end of the movable ruler in a rotating way; and the right end of the fixed ruler is provided with a set square and a straight ruler in a rotating way. The central line of the fixed ruler is overlapped with a 0-degree graduation line of the protractor; and the fixed ruler is overlapped with the central line of the movable ruler. The novel mathematic multi-purpose ruler has the beneficial effects that: the mathematic multi-purpose ruler has a simple structure and is convenient to carry; tools are concentrated on one fixed ruler; the mathematic multi-purpose ruler is not only convenient to carry but also good for storage; and the right end of the fixed ruler is provided with the set square and the straight ruler, so that the straight ruler can be spread for use when the length of the fixed ruler is insufficient.
Description
Technical field
The utility model relates to a kind of ruler, a kind of specifically novel mathematics multipurpose ruler.
Background technology
Ruler is a math teacher at school the time, one of necessary tool, and the ruler of giving a lesson needs a lot, needs the very effort of taking of a part, and is not easy to take, and when drawing straight line, short ruler is too short, and that long ruler carries is very inconvenient.
Summary of the invention
To above deficiency, it is a kind of simple in structure that the utility model provides, the novel mathematics multipurpose ruler in multiple ruler in one.
For achieving the above object; The technical scheme of the utility model is: a kind of novel mathematics multipurpose ruler; Comprise fixed ruler, adjustable rule, it is characterized in that: be respectively equipped with center line on described fixed ruler and the adjustable rule, the left end of fixed ruler is fixed with protractor; The fixed ruler left end is rotatably connected with the adjustable rule left end, and the rotation of fixed ruler right-hand member is provided with set square and ruler.
The center line of described fixed ruler overlaps fixed ruler and adjustable rule central lines with 0 degree graduation mark of protractor.
The beneficial effect of the utility model is: simple in structure, easy to carry, instrument is concentrated on the fixed ruler, and both easy to carry, be beneficial to again and deposit, set square that the fixed ruler right-hand member is provided with and ruler can launch ruler to use when fixed ruler length is not enough.
Description of drawings
Fig. 1 is the structural representation of the utility model.
1 fixed ruler, 2 adjustable rules, 3 center lines, 4 protractors, 5 set squares, 6 rulers among the figure.
The specific embodiment
