Abstract
The utility model relates to a multifunctional straight rule and belongs to the technical fields of mathematical education tools. Through the technical scheme of the utility model, the multifunctional straight rule comprises a straight rule and is characterized in that a zero point of the straight rule is provided with a locating needle, the upper end of the locating needle is provided with a rotary shaft, a motor is arranged on the rotary shaft, the straight rule is provided with a sleeve, the side surface of the sleeve is provided with a pen clipper, and a locating nut is arranged at the middle section of the sleeve. The multifunctional straight rule disclosed by the utility model has a simple structure, is simple and convenient in operation, time-saving and labor-saving when drawing a circle and measuring the length, the radius and the diameter in a mathematical education process, and can be used for reducing the work difficulty of a teacher.
Description
Technical field: the utility model belongs to mathematical education apparatus technical field, is a kind of multi-functional ruler specifically.
Background technology: at present, the general ruler that uses is measured length in the mathematical education process, justifies with compasses; Diameter of a circle, radius also often need be measured with ruler; Operating so very bothers, wastes time and energy, and is not easy to carry, and has increased work difficulty to the teacher.
Summary of the invention: the purpose of the utility model provides a kind ofly to be made circle and measures length and easy and simple to handle, time saving and energy saving multi-functional ruler when radius, diameter in the mathematical education process.
The technical scheme of the utility model is: comprise ruler, it is characterized in that being provided with pilot pin at ruler on zero point that the pilot pin upper end is provided with rotating shaft, rotating shaft is provided with motor, and ruler is provided with sleeve pipe, and the sleeve pipe side is provided with pen clip, and the sleeve pipe stage casing is provided with setscrew nut.
The beneficial effect of the utility model is: the utility model is simple in structure, and is easy and simple to handle, time saving and energy saving when in the mathematical education process, making circle and measurement length and radius, diameter, alleviated teacher's work difficulty.
Description of drawings: accompanying drawing 1 is the structural representation of the utility model.
Among the figure 1, ruler, 2, pilot pin, 3, rotating shaft, 4, motor, 5, sleeve pipe, 6, pen clip, 7, setscrew nut.
The specific embodiment: comprise ruler 1, it is characterized in that being provided with pilot pin 2 at ruler on 1 zero point that pilot pin 2 upper ends are provided with rotating shaft 3, rotating shaft 3 is provided with motor 4, and ruler 1 is provided with sleeve pipe 5, and sleeve pipe 5 sides are provided with pen clip 6, and sleeve pipe 5 stage casings are provided with setscrew nut 7.When in the mathematical education process, making circle and measurement length and radius, diameter, pen clip 6 clamp chalks are regulated sleeve pipe 5 and fixing with setscrew nut 7, hold motor 4 pilot pin 2 is fixed in a bit, open motor 4, and rotating shaft 3 rotation drive rulers 1 are made circle and got final product.
