An internal sliding rod 15 is slidably connected inside the drawing rod 6. An inward retraction rod 13 is fixedly connected to the end of the internal sliding rod 15 away from the drawing rod 6. A limit post 11 is fixedly connected to the position of the inward retraction rod 13 near the drawing groove 7. The limit post 11 is slidably connected inside the drawing groove 7. A drive shaft 8 is also threadedly connected to the inward retraction rod 13. A third fastening handle 12 is fixedly connected to the top of the drive shaft 8. A roller 18 is also fixedly connected to the end of the drive shaft 8 away from the third fastening handle 12. The roller 18 is also slidably connected inside the sliding groove 4. A scale 5 is provided on the surface of the drawing board 3.

[0027] When architectural drawings need to be drawn, the fastening bolts on one side of the support frame 1 are tightened to fix the drawing board 3. The drawing rod 6 is pulled to move it to the required drawing position according to the scale of the ruler 5. When the drawing rod 6 is pulled, the drive shaft 8 and the roller 18 slide inside the sliding groove 4. The first fastening handle 2 and the third fastening handle 12 at the top of the drive shaft 8 are rotated, which in turn drives the drive shaft 8 to rise inside the first fastening handle 2 and the third fastening handle 12, which in turn drives the roller 18 to press against the sliding groove 4, thus fixing the drawing rod 6. The drawing pen is inserted into the round hole on the sliding block 9, and the sliding block 9 is pulled to drive the internal sliding shaft 21 to slide inside the drawing groove 7, thus enabling horizontal lines to be drawn on the drawing. When vertical lines are needed... When drawing lines, the second fastening handle 10 is rotated, allowing one end of the second fastening handle 10 to be threaded into the interior of the sliding block 9, pressing against the surface of the drawing rod 6, thereby fixing the sliding block 9. At this time, the first fastening handle 2 and the third fastening handle 12 are loosened, so that the roller 18 no longer presses against the interior of the sliding groove 4. Therefore, the drive shaft 8 and the roller 18 can slide inside the sliding groove 4, thereby driving the drawing rod 6 to move vertically inside the drawing board 3, enabling vertical drawing of lines on the drawing paper. Therefore, it provides a stable and flat drawing surface for the drawing paper, effectively avoiding paper shaking or wrinkles, facilitating accurate drawing of each line, ensuring the accuracy of the design drawings, and reducing construction problems caused by drawing errors.

[0028] An internal sliding block 19 is fixedly connected to the end of the line drawing rod 6 away from the first fastening handle 2. An internal sliding plate 20 is fixedly connected to both sides of the internal sliding block 19. An internal sliding groove 16 is opened inside the internal sliding rod 15. The internal sliding plate 20 is slidably connected inside the internal sliding groove 16. The internal sliding block 19 is slidably connected between the internal sliding rods 15. A tension spring 17 is fixedly connected to one side of the retracting rod 13. The end of the tension spring 17 away from the retracting rod 13 is fixedly connected to one side of the internal sliding block 19.

[0029] When drawing slanted lines, loosen the first fastening handle 2 and the third fastening handle 12, pull the drawing rod 6 and the inward rod 13 to tilt them, and then let the internal sliding rod 15 slide inside the drawing rod 6. When the internal sliding block 19 slides, it will pull the tension spring 17 to deform and expand. When the angle of the drawing rod 6 is adjusted, tighten the first fastening handle 2 and the third fastening handle 12, insert the drawing pen into the round hole on the sliding block 9, and let the sliding block 9 drive the internal sliding shaft 21 to slide inside the drawing groove 7 on the drawing rod 6. Thus, when drawing slanted lines and lines at specific angles, there is no need to use additional tools such as rulers and triangles for frequent measurement. You can directly follow the scale guidance on the drawing board to complete the drawing efficiently and accurately, which greatly improves the drawing efficiency and makes the line quality more stable.

[0030] Working principle:

[0031] When architectural drawings are needed, the fastening bolts on one side of the support frame 1 are tightened to fix the drawing board 3. The drawing rod 6 is pulled to move it to the required drawing position according to the scale of the ruler 5. When the drawing rod 6 is pulled, the drive shaft 8 and the roller 18 slide inside the sliding groove 4. The first fastening handle 2 and the third fastening handle 12 at the top of the drive shaft 8 are rotated, which in turn causes the drive shaft 8 to rise inside the first fastening handle 2 and the third fastening handle 12, which in turn causes the roller 18 to press against the sliding groove 4, thus fixing the drawing rod 6. The drawing pen is then inserted into the round hole on the sliding block 9. Pulling the sliding block 9 causes the internal sliding shaft 21 to slide inside the drawing groove 7, thereby enabling horizontal lines to be drawn on the drawing. When vertical lines are needed, the second fastening handle 10 is rotated, allowing one end of the second fastening handle 10 to be threaded into the sliding block 9 and press against the surface of the drawing rod 6, thereby fixing the sliding block 9. At this time, the first fastening handle 2 and the third fastening handle 12 are loosened, so that the roller 18 no longer presses against the inside of the sliding groove 4. Therefore, the drive shaft 8 and the roller 18 can slide inside the sliding groove 4, thereby enabling the drawing rod 6 to move vertically inside the drawing board 3.

[0032] When it is necessary to draw a slanted line, loosen the first fastening handle 2 and the third fastening handle 12, pull the drawing rod 6 and the inner retraction rod 13 to make it tilt, so that the inner sliding rod 15 slides inside the drawing rod 6. When the inner sliding block 19 slides, it will pull the tension spring 17 to deform and expand. When the angle of the drawing rod 6 is adjusted, tighten the first fastening handle 2 and the third fastening handle 12, insert the drawing pen into the round hole on the sliding block 9, so that the sliding block 9 drives the inner sliding shaft 21 to slide inside the drawing groove 7 on the drawing rod 6.

[0033] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
