Abstract

The utility model relates to an auxiliary tool for teaching, in particular to a line drawing tool for teaching of English, Chinese and music. The utility model aims at providing a line drawing tool for teaching, which is simple in structure and convenient, and capable of regulating the space and length of lines and finishing line drawing once. The line drawing tool comprises a frame (1), a fixing frame (2), a mark box (3) on the fixing frame (2) and a cord storage box (4) connected with the back of the mark box (3). The main principle is to stir five flexible cords which are in random lengths and marked by the mark box (3), so as to finish line drawing and to regulate the space between cords by a positioning sliding block and a limit sliding block. The line drawing tool has the beneficial effects that the space between the drawn lines can be regulated, and the length of the straight line drawn once is unlimited by the device and the tool has the advantages of rationality in design, simplicity in structure, convenience in use and carrying, saving time and labor and improving the efficiency.

Description

Teaching setting-out lattice instrument

Technical field

The utility model relates to a kind of assistant teaching aid of the usefulness of imparting knowledge to students, and is specially a kind ofly to relate to teaching that English, Chinese language, music teaching uses with setting-out lattice instrument.

Background technology

At present in the classroom instruction of middle and primary schools' English, Chinese language, music, the teacher often need draw four line lattice and carry out the teaching of English, phonetic on blackboard, draw staff and carry out the teaching of music, the teacher comes picture four line lattice and staffs with long ruler during setting-out, and the better five line screen works of being made by batten of just using come picture four line lattice and staffs; But not only waste time and energy with the ruler setting-out, and line-spacing also is difficult to hold, come picture with five line lattice, though efficient increases,, use very inconvenient because it is relatively heavier, often a people is difficult to operation, and the once drawn straight length of ruler and five line lattice is limited, when continuing the picture straight line again, is difficult to guarantee its consistent level.Given birth to the instrument of various setting-out lattice therefrom, as the patent No. is the described music stave of 01239629.X Chinese patent, English stave paintbrush, though it has overcome above-mentioned part shortcoming, but its line compartment is apart from non-adjustable, and manual operations the time can not guarantee the level of its drawn line, and for example the patent No. is 201020014563.3 the described teaching of Chinese patent parallel lines scoring tool, though its line compartment is apart from adjustable, but the length of drawn straight line is limited again, is difficult to guarantee continuously the consistent level of drawn straight line several times.
