Abstract
The utility model discloses a mathematical teaching ruler comprising a ruler body, wherein the position on the ruler body, which is close to the end part, is provided with a protractor plate, a compass ruler is hinged on the ruler body, a sliding block which can slide along the compass ruler is arranged on the compass ruler, a chalk sleeve hole is arranged on the sliding block, compass scales are arranged on the compass ruler, protractor scales are arranged on the protractor plate, and an arc-shaped pen groove is arranged on the protractor plate. When the mathematical teaching ruler is used, the mathematical teaching ruler disclosed by the utility model is placed on a blackboard, the ruler body is used for drawing a straight line, the protractor plate is used for measuring the angle and drawing an angle, and the compass ruler is used for drawing a circle. The mathematical teaching ruler disclosed by the utility model is convenient to use, can be used for drawing various geometric shapes by one step and is convenient for teaching and administrative staff to teach.
Description
Technical field
The utility model relates to a kind of teaching appliance, particularly a kind of mathematical education chi.
Background technology
The middle school teacher usually needs to carry multiple teaching ruler in teaching, such as compasses, ruler and protractor etc., traditional mode is once to carry multiple teaching appliance, has caused teaching and administrative staff personnel's work inconvenience, has increased teaching and administrative staff's working strength.
The utility model content
The technical problems to be solved in the utility model is the deficiency at technique scheme, and the teaching of providing convenience alleviates a kind of mathematical education chi of intensity of workers.
For addressing the above problem the technical solution of the utility model be:
A kind of mathematical education chi comprises the chi body, and the position near the end on the described chi body is provided with the protractor plate, is hinged with the compasses chi on the described chi body, and described compasses chi is provided with can be along the slide block of compasses chi slip, and described slide block is provided with the chalk trepanning.
Below be to further improvement in the technical proposal:
