Description

Technical Field

[0001] This utility model relates to the field of line drawing tools, specifically a stave line drawer that avoids tilting. Background Technology

[0002] Music is an art form that reflects human emotions in real life. Music can be divided into two main types: vocal music and instrumental music. It can also be roughly divided into classical music, folk music, original music, and modern music. Music can improve people's aesthetic ability, purify people's minds, and establish lofty ideals. We express our emotions through music, allowing many of our feelings to be released.

[0003] In music learning, learning to draw musical notation is an essential part. Drawing musical notation and notes helps students better understand and master musical symbols. However, in drawing musical notation, the lines are all parallel. During the drawing process, the lines often cross or are not parallel due to slanted drawing. This will seriously affect the drawing of subsequent notes. To address the above problems, we provide a staff line writer that avoids slant and solves the aforementioned issues.

The handle block 7 has an internal mounting component for mounting pen refills; the mounting component includes several pen refill slots 25, all located inside the handle block 7, arranged in a straight line. The handle block 7 has third locking knobs 15 on both sides corresponding to the pen refill slot 25 for fixing the pen refill; finger grooves are provided on both sides of the upper end of the handle block 7; before use, the required pen refill is inserted into the pen refill slot 25, and then the pen refill is fixed by the third locking knobs 15. When drawing, hold the handle block 7 and press down to make the pen tip contact the paper, and then pull the handle block 7 to make the rectangular block 21 slide along the sliding rod 9 to draw a line. After drawing the line, release the handle block 7, and the handle block 7 will return to its original position under the action of the spring 23, so that the pen tip is removed from the paper.

[0027] One end of the placement plate 1 is provided with an anti-tilt component to prevent paper tilting. The anti-tilt component includes a reference plate 10, which is fixedly connected to one end of the placement plate 1. A fixing plate 14 is fixedly connected to the middle of the reference plate 10. First limiting slide rods 18 are slidably connected to both sides of the fixing plate 14. A front pressure plate 8 is fixedly connected between the lower ends of the first limiting slide rods 18.

Handles 17 are fixedly connected to the upper ends of the first threaded rod 16 and the second threaded rod 20. In use, one end of the paper is aligned with the reference plate 10, and then the first threaded rod 16 is rotated by the handle 17. The rotation of the first threaded rod 16 can drive the front pressure plate 8 to move, thereby fixing the end of the paper by the front pressure plate 8, thus preventing the paper from tilting during the drawing process.

[0028] A fixing assembly for securing the tail of the paper is also provided between the two side slide rails 3; the fixing assembly includes a crossbar 2, on both sides of the crossbar 2 are slidably connected to second limiting slide rods 19, and the lower ends of the second limiting slide rods 19 are fixedly connected to a rear end pressure plate 13. A second threaded rod 20 is threadedly connected to the middle of the crossbar 2, and the lower end of the second threaded rod 20 is rotatably connected to the rear end pressure plate 13. Both ends of the crossbar 2 are provided with sliding assemblies for sliding with the side slide rails 3; the sliding assembly includes two sliding seats 4, which are respectively fixedly connected to the positions at both ends of the crossbar 2. The seat 4 is slidably connected to the side slide rails 3 on both sides. Each sliding seat 4 is provided with a second locking knob 12 for locking the position of the sliding seat 4. In use, the second threaded rod 20 is rotated by the handle 17. The rotation of the second threaded rod 20 can drive the rear pressure plate 13 to move, thereby clamping and fixing the tail of the paper to prevent the paper from becoming skewed during the drawing process. At the same time, the position of the crossbar 2 can be adjusted through the sliding seat 4, so that the position of the crossbar 2 can be adjusted according to the size of the paper. The second locking knob 12 is used to lock the position of the sliding seat 4.

[0029] The working principle of this utility model is as follows: When in use, the paper is placed on the placement plate 1 and aligned with the reference plate 10. Then, the first threaded rod 16 is rotated by the handle 17. The rotation of the first threaded rod 16 can move the front pressure plate 8, which fixes the end of the paper. After the end of the paper is fixed, the second threaded rod 20 is rotated by the handle 17 at the upper end of the second threaded rod 20. The rotation of the second threaded rod 20 can move the rear pressure plate 13, thereby clamping and fixing the end of the paper to prevent the paper from becoming skewed during the drawing process. When drawing, hold the handle block 7 and press down to make the pen tip contact the paper. Then pull the handle block 7 to make the rectangular block 21 slide along the sliding rod 9 to draw a line. After drawing the line, release the handle block 7. The handle block 7 returns to its original position under the action of the spring 23, so that the pen tip is removed from the paper.
