Abstract

The utility model relates to a novel multifunctional drawing rule, comprising a first drawing scale rule. A slot is formed on the first drawing scale rule and one end of a second drawing scale rule is spliced into the slot and another end is provided with a chalk clamping device. The chalk clamping device is composed of a left clamper, a right clamper and a spring and a semi-round groove is respectively arranged on the left clamper and the right clamper. An angle gage is hinged on the upper surface of the first drawing scale rule and a plastic sucker is fixed on the lower surface of the first drawing scale rule. The drawing work is accomplished using the relative small volume and while in use, the second drawing scale rule is taken out from the slot of the first drawing ruler and after use, the second drawing scale rule is inserted into the slot again and the compasses function is realized by the chalk clamping device fixed on the second drawing scale rule, so as to draw the round or arc. The rule has many functions.

Description

The Multifunction drawing rule
Technical field:
The utility model relates to the stationery technical field, relates to a kind of drawing rule in particular.
Background technology:
When the schoolman is teaching mathematics class, often will use rule and map, rule commonly used now is to be made of a chi body that has scale, but present rule is seen to the student because will map on blackboard, so the volume of ruler is bigger, carry the also inconvenience of ten minutes.And present rule effect is more single, also to carry the bigger drawing instrument of the such volume of compasses and protractor during mapping, though these instruments can be put into the drawing instrument box obsolete the time carries together, but bigger volume still make the teacher carry very inconvenient, and when mapping multiple instrument be used alternatingly also influence mapping efficient, lose time.
The utility model content:
The purpose of this utility model is to provide a kind of Multifunction drawing rule at the deficiencies in the prior art part, can overcome the deficiencies in the prior art part, it has functions such as the length of measurement, angular surveying, compasses picture, accomplished the many usefulness of a chi, and volume is little, simple in structure.
Technology solution of the present utility model is as follows:
The Multifunction drawing rule comprises the first drawing rule, forms slot on the described first drawing rule, and the second drawing rule, one end is plugged in the described slot, and the other end is fixed with the chalk clamping device.
Described Multifunction drawing rule, described chalk clamping device is made of left clamp, right clamping body and spring, has semi-circular groove on described left clamp, the right clamping body.
Described Multifunction drawing rule, the hinged protractor that is equipped with on the upper surface of the described first drawing rule.
Described Multifunction drawing rule, the lower surface of the described first drawing rule is fixed with the plastics sucker.
Described Multifunction drawing rule, the chi body length of the described second drawing rule is less than the cell body length of described slot.
The utility model beneficial effect is:
1, the utility model is fixed with the second drawing rule of chalk clamping device by pegging graft in the slot of the first drawing rule, make the utility model to finish drawing work with smaller volume, the second drawing rule can be pulled out in the slot of first drawing rule when in use, turn back to again after the use, and by chalk clamping device fixing on the second drawing rule, can also realize the function of compasses, can draw circle or circular arc have accomplished that a chi uses more.
2. chalk clamping device described in the utility model is made of left clamp, right clamping body and spring, has semi-circular groove on described left clamp, the right clamping body, and the existence of these two semicircular grooves helps chalk is put into wherein.
3. the hinged protractor that is equipped with on the upper surface of the described first drawing rule.Can be used for the usefulness that when drawing, takes measurement of an angle.
4. the lower surface of the described first drawing rule is fixed with the plastics sucker, can hold the surface of blackboard when drawing, and helps the fixing of drawing rule, more helps drawing.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:

The specific embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
Embodiment, see shown in the accompanying drawing 1~2: the Multifunction drawing rule, comprise the first drawing rule 1, form slot 101 on the described first drawing rule 1, the second drawing rule, 2 one ends are plugged in the described slot 101, and the other end is fixed with chalk clamping device 3.
Described chalk clamping device 3 is made of left clamp 301, right clamping body 302 and spring 303, has semi-circular groove 301a, 302a on described left clamp 301, the right clamping body 302.
The hinged protractor 4 that is equipped with on the upper surface of the described first drawing rule 1.
The lower surface of the described first drawing rule 1 is fixed with plastics sucker 5.
The chi body length of the described second drawing rule 2 is less than the cell body length of described slot 101.Such second drawing rule 2 just can insert in the slot 101 completely, only stays chalk clamping device 3 to be exposed, and has accomplished that the volume of whole drawing rule minimizes, and not only be beneficial to and carry, and better appearance.
Operation principle: when in use, earlier set chalk having on the chalk clamping device 3, utilize plastics sucker 5 that whole drawing rule is inhaled on blackboard again, the second drawing rule 2 is pulled out in slot 101, with plastics sucker 5 is just can draw in the center of circle, when needs take measurement of an angle, can measure by utilization hornwork 4.
