Obviously, the described embodiments are part of the embodiments of the present application, not all. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0035] The present embodiment discloses Figures 1 to 5The drawing aid for mathematical learning includes a mathematical drawing aid assembly 1, which is the basic framework of the entire device and integrates other components to provide a complete drawing tool for users. The mathematical drawing aid assembly 1 includes a ruler 2 and a plurality of geometric shape holes 5 opened on the surface of the ruler 2. The surface of one end of the ruler 2 has a scale line 4. The ruler 2 provides a straight edge for drawing straight lines and is the carrier of other components such as the scale line 4, the geometric shape hole 5, and the sliding groove 8. It allows users to draw lines of different lengths and patterns as needed. The geometric shape hole 5 is preset on the ruler 2 in various shapes, helping students quickly draw common geometric shapes, improving drawing efficiency. The center of the end of the ruler 2 opposite to the scale line 4 is slidingly connected with an adjustable center component 10. One side of the adjustable center component 10 and located at the end of the ruler 2 is slidingly connected with an adjustable radius component 9. The adjustable radius component 9 and the adjustable center component 10 both include an L slider seat 7 slidingly connected to the end of the ruler 2. The adjustable radius component 9 further includes a detachable pen sleeve 13 detachably mounted on the L slider seat 7 of the adjustable radius component 9. The detachable pen sleeve 13 is used to insert the drawing pen. When drawing a circle, the adjustable radius component 9 and the adjustable center component 10 are slidingly connected. The adjustable center component 10 is the center, and the adjustable radius component 9 is used to insert the drawing pen. At the same time, the adjustable radius component 9 and the adjustable center component 10 can be adjusted in position according to the needs of the required circle radius. When the required circle radius is smaller than half the length of the ruler 2, the adjustable center component 10 is stationary at the center of the ruler 2. The pen is inserted into the adjustable radius component 9, and the ruler 2 is rotated around the adjustable center component 10 to draw a circle with a radius smaller than half the length of the ruler 2. When the required circle radius is greater than half the length of the ruler 2, the adjustable center component 10 needs to be retreated from the original center position to increase the distance between the adjustable center component 10 and the adjustable radius component 9, thereby increasing the drawing stroke. The pen is inserted into the adjustable radius component 9, and the ruler 2 is rotated around the adjustable center component 10 to draw a circle with a radius greater than half the length of the ruler 2.

[0036] In this embodiment, the outer wall of the ruler 2 opposite to the scale line 4 is provided with a sliding groove 8. The inner wall of each L slider seat 7 is integrally connected with a sliding block 19, and the sliding block 19 is adapted to slide in the sliding groove 8. The L slider seat 7 serves as the sliding base of the adjustable radius component 9 and the adjustable center component 10, allowing them to move smoothly on the ruler 2. The sliding groove 8 provides a track for the L slider seat 7 and the connected components, ensuring smooth sliding along the length of the ruler 2. It is worth noting that all sliding in this scheme is damping sliding to facilitate the initial positioning of the slider seat.

[0037] In this embodiment, the outer wall of the L slider base 7 of the adjustable radius component 9 is provided with a slot 22, and the outer wall of the detachable pen sleeve 13 is fixedly provided with a plug rod 25 matched with the slot 22. The detachable pen sleeve 13 is used for installing a drawing pen, and different pen cores can be easily replaced to adapt to different drawing requirements.

[0038] In this embodiment, the extended inner wall (i.e. the bottom surface) of the slot 22 is bonded with a first magnet block 23, and the outer wall of the plug rod 25 is bonded with a second magnet block 24. When the plug rod 25 is inserted into the slot 22, the second magnet block 24 and the first magnet block 23 are magnetically attracted. The first magnet block 23 cooperates with the second magnet block 24 to enhance the connection stability between the detachable pen sleeve 13 and the adjustable radius component 9 by magnetic adsorption, and facilitates the replacement of different specifications of the detachable pen sleeve 13.

[0039] In this embodiment, the L slider base 7 of the adjustable radius component 9 is fixedly connected with an extended ear plate 14, the top surface of the extended ear plate 14 is longitudinally screw-connected with a center screw 20, and the bottom end of the center screw 20 longitudinally penetrates through the extended ear plate 14 and is integrally connected with a center needle 15.

[0040] In this embodiment, the top surface of the L slider base 7 of the adjustable radius component 9 is longitudinally screw-penetrated with a first locking bolt 18, and the bottom screw end of the first locking bolt 18 is connected with the ruler 2.

[0041] In this embodiment, the top surface of the L slider base 7 of the adjustable radius component 9 is longitudinally screw-penetrated with a second locking bolt 21, and the bottom screw end of the second locking bolt 21 is pressed against the top surface of the ruler 2.

[0042] In this embodiment, the ruler 2 is provided with a fixed center 16 at the center position of the top surface of one side close to the sliding groove 8, and a plurality of adjustable centers 17 are provided at equal distances on one side of the fixed center 16 and on the top surface of the ruler 2.

[0043] In this embodiment, the first locking bolt 18 abuts against the fixed center 16 or one of the adjustable centers 17. When the required drawing size is less than half the length of the ruler 2, the center needle 15 is located at the fixed center 16 at the center position of the ruler 2, the first locking bolt 18 is connected with the fixed center 16 for limiting the extension of the extended ear plate 14 and the center needle 15, and the displacement is reduced. When the required drawing size is greater than half the length of the ruler 2, the L slider base 7 of the adjustable radius component 9 is retreated, the first locking bolt 18 abuts against one of the adjustable centers 17, and the drawing stroke is increased. The center needle 15 is used as the center when drawing a circle to ensure the accuracy of the center point. In addition, a scale alignment line or an extended index member can be further provided on the L slider base 7 to facilitate alignment with the scale lines of the scale ruler to read the radius of the drawn circle.

[0044] In this embodiment, the ruler 2 is internally provided with a plug-in cavity 11, and a pull-out auxiliary ruler 6 is plugged into the plug-in cavity 11. The geometric pattern hole 5 is filled and supported from the middle by the pull-out auxiliary ruler 6. One end of the pull-out auxiliary ruler 6 is connected with a pull ring 12. At the same time, the pull-out auxiliary ruler 6 can support multiple geometric pattern holes 5, reduce the stress of multiple geometric pattern holes 5, and reduce the risk of breaking the ruler 2. The ruler 2 is provided with a drawing support slope body 3 at the end opposite to the sliding groove 8, and the drawing support slope body 3 is adjacent to one side of the scale line 4. The pull-out auxiliary ruler 6 is inserted into the ruler 2 through the plug-in cavity 11, which can extend the effective length of the ruler 2, and also be used to support the geometric pattern hole 5, reducing the risk of damage caused by stress concentration.

[0045] Working principle:

[0046] The drawing aid for mathematical learning checks whether the ruler 2 is clean and undamaged, and ensures that the scale line 4 is clear. At the same time, it confirms that all movable parts such as the pull-out auxiliary ruler 6 and the L-shaped slider seat 7 are in normal use. Using the edge of the ruler 2 as a guide, the user can draw a straight line with a pencil or other drawing tools along the edge of the ruler 2. If a longer straight line is needed, the pull-out auxiliary ruler 6 can be pulled out and used in combination with the ruler 2 to extend the working range.

[0047] The ruler 2 is pre-provided with geometric pattern holes 5, and the user can directly use these templates to quickly draw common geometric shapes according to needs. In order to improve accuracy, the pencil can be used to draw the edge of the geometric pattern hole 5 while the paper is fitted to the edge of the geometric pattern hole 5.

[0048] Place the center needle 15 at the desired center position, and fix the position of the center needle 15 or the adjustable center component 10 by the first locking bolt 18. According to the size of the radius of the circle to be drawn, adjust the adjustable radius component 9 to the appropriate position, and lock it with the second locking bolt 21. Insert the drawing pen into the detachable pen sleeve 13, and then install the pen sleeve on the plug rod 25, ensuring that the pen tip is at a specified distance outside the center needle 15. Gently turn the entire device, so that the pen tip rotates around the fixed center needle 15, thereby drawing a complete circle.

[0049] If the radius of the circle or the position of the center of the circle needs to be changed, the corresponding locking bolt can be loosened, adjusted and locked again. The scale line 4 on the ruler 2 is used to measure or mark a specific length. For longer distances, the pull-out auxiliary ruler 6 can be used in combination. During use, if a different type of drawing pen is needed, the old pen can be easily removed and a new pen can be installed by loosening the connection between the first magnet block 23 and the second magnet block 24 and the insertion rod 25. For the L-shaped slider seat 7 and its associated adjustable radius component 9 and adjustable center component 10, they can be freely moved to the desired position through the sliding groove 8, and locked with the locking bolt to keep stable.

[0050] It should be understood that those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes shall belong to the protection scope of the appended claims of the utility model.
