Abstract
The invention discloses a kind of higher mathematics plotters for facilitating teaching, including the first ruler, the second ruler, shaft, laser lamp and laser lamp switch, it is rotatablely connected between first ruler and one end of second ruler by the shaft, the inside edge of first ruler and second ruler is provided with ruler scale, is provided with laser lamp and laser lamp switch on first ruler and second ruler.Compared with prior art, multiple laser lamps are set on the ruler that the present invention is relatively rotated at two, when in use, the straight line, cross spider, angle line etc. of needs are shown on drawing or blackboard as needed, easy to use, demonstration is convenient, convenient for teaching, have the value of popularization and application.
Description
Technical field
The present invention relates to a kind of mathematics drawing tool more particularly to a kind of higher mathematics plotters for facilitating teaching.
Background technique
In student's (except mathematics major, the analysis of mathematics major immunologing mathematics) of all kinds of professions of Chinese science and engineering, mathematics
More difficult, textbook often claims " higher mathematics "；In Higher Mathematics Teaching, drawing be it is frequent, the drawing of the prior art passes through ruler
The drawing tools such as son, set square, but drawing efficiency is low, and it is inconvenient to show, accordingly, there exist rooms for improvement.
Summary of the invention
The object of the invention is that providing a kind of higher mathematics drawing for facilitating teaching to solve the above-mentioned problems
Instrument.
The present invention through the following technical solutions to achieve the above objectives:
The present invention includes the first ruler, the second ruler, shaft, laser lamp and laser lamp switch, first ruler and institute
It states and is rotatablely connected between one end of the second ruler by the shaft, the inside edge of first ruler and second ruler
It is provided with ruler scale, is provided with laser lamp and laser lamp switch on first ruler and second ruler.
Preferably, the laser lamp and the laser lamp switch are multiple, and each laser lamp is correspondingly arranged one
A laser lamp switch, multiple laser lamps are respectively arranged at the 5mm of the ruler scale.
As an improvement, being provided with shaft scale and shaft tuning drive gear in the shaft.
The beneficial effects of the present invention are:
The present invention is a kind of higher mathematics plotter for facilitating teaching, and compared with prior art, the present invention is in two phases
To multiple laser lamps are arranged on the ruler of rotation, when in use, the straight line of needs are shown on drawing or blackboard as needed, is handed over
Cross wires, angle line etc., easy to use, demonstration is convenient, convenient for teaching, has the value of popularization and application.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the fully open schematic diagram of laser lamp；
Fig. 3 is the schematic diagram that laser lamp partially opens.
In figure: the first ruler of 1-, the second ruler of 2-, 3- shaft, 4- ruler scale, 5- laser lamp, 6- laser lamp switch, 7-
Shaft scale, 8- shaft tuning drive gear.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings:
As shown in Figure 1 to Figure 3: the present invention includes that the first ruler 1, the second ruler 2, shaft 3, laser lamp 5 and laser lamp are opened
6 are closed, is rotatablely connected between first ruler and one end of second ruler by the shaft, first ruler and institute
The inside edge for stating the second ruler is provided with ruler scale 4, is provided on first ruler and second ruler sharp
Light lamp and laser lamp switch.
Preferably, the laser lamp and the laser lamp switch are multiple, and each laser lamp is correspondingly arranged one
A laser lamp switch, multiple laser lamps are respectively arranged at the 5mm of the ruler scale.
As an improvement, being provided with shaft scale 7 and shaft tuning drive gear 8 in the shaft.
Basic principles and main features and advantages of the present invention of the invention have been shown and described above.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and its
Equivalent thereof.
