[0027] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0028] Please see the appendix Figure 1 -Appendix Figure 5 This utility model discloses an easily adjustable auxiliary drawing tool for architectural engineering design, comprising a drawing base plate 11, with grooves 12 on its surface. A connector 13 is fixedly installed at the bottom of the drawing base plate 11, and the connector 13 is movably connected to a lifting column 15 via bolts 14. By cooperating with the connector 13 and bolts 14, the angle between the drawing base plate 11 and the ground can be adjusted, allowing the user to find the most suitable drawing angle and reduce fatigue caused by prolonged use. A support column 16 is provided at the bottom of the lifting column 15, with multiple recesses 17 on its surface. A circular groove 21 is provided at the front end of the support column 16, and a lock is movably installed inside the circular groove 21. With the cylinder 22 fixed, place the paper 301 on the surface of the groove 12, turn the four knobs 33 counterclockwise to pull up the pressure plate 32, put the four corners of the paper 301 under the pressure plate 32, turn the knobs 33 clockwise to press the pressure plate 32 to fix the paper 301. Multiple sheets of paper 301 can be fixed at the same time. Pressing the drawing base plate 11 can adjust the angle between the drawing base plate 11 and the lifting column 15. When the height needs to be adjusted, pull the push-pull handle 25 outward to move the locking cylinder 22 and the circular abutment 24. Move the lifting column 15 up and down to the appropriate position. Under the force of the spring 23, the circular abutment 24 rebounds and is inserted into the recess 17 to complete the fixation.

[0029] The support column 16 has a cavity inside, into which the lifting column 15 is inserted. A circular abutment 24 is fixedly installed at one end of the locking column 22, and the circular abutment 24 is inserted into the recess 17. A push-pull handle 25 is fixedly installed at the other end of the locking column 22. A spring 23 is sleeved on the surface of the locking column 22, and one end of the spring 23 is fixedly connected to the circular abutment 24. By coordinating the locking column 22, spring 23, circular abutment 24, and push-pull handle 25, pulling the push-pull handle 25 moves the locking column 22 and circular abutment 24, moving the lifting column 15 up and down to the appropriate position. Under the force of the spring 23, the circular abutment 24 springs back and inserts into the recess 17. This allows adjustment of the drawing tool's height, enabling users to find the most suitable drawing posture, reducing fatigue from prolonged drawing, improving drawing efficiency, ensuring the drawing tool remains stable during the drawing process, and reducing the risk of accidents caused by improper use. To mitigate drawing errors caused by tool wobbling, the other end of spring 23 is fixedly connected to support column 16. Four pressure structures are fixedly installed on the surface of groove 12, including screw post 31. Pressure plate 32 is sleeved on the outer surface of screw post 31. A knob 33 is threadedly connected to the top of screw post 31. By setting screw post 31, pressure plate 32 and knob 33 to form a pressure structure, the paper is kept flat and stable during the drawing process, reducing drawing errors caused by paper wobbling or movement. This is especially important for engineering design drawings that require high precision. It can ensure the reliability of the drawings, evenly distribute the pressure of the drawing tool on the paper, thereby protecting the paper from damage and extending its service life. It can significantly improve the drawing experience and satisfaction of the drafter. Paper 301 is set at the bottom of pressure plate 32. The four pressures are arranged in a row. A square support plate is fixedly installed at the bottom of support column 16.

[0030] Working principle:

[0031] First, lay the paper 301 on the surface of the groove 12, turn the four knobs 33 counterclockwise to pull up the pressure plate 32, put the four corners of the paper 301 under the pressure plate 32, turn the knobs 33 clockwise to press the pressure plate 32 to fix the paper 301. Multiple sheets of paper 301 can be fixed at the same time. Pressing the drawing base plate 11 can adjust the angle between the drawing base plate 11 and the lifting column 15. When the height needs to be adjusted, pull the push-pull handle 25 outward to move the locking column 22 and the circular abutment 24. Move the lifting column 15 up and down to the appropriate position. Under the action of the spring 23, the circular abutment 24 rebounds and is inserted into the recess 17 to complete the fixation. At this point, the entire process is completed.
