The telescopic rod 8 and the spring 9 are fixedly connected on the other side of the limiting plate 6 and in the drawing ruler one 1 respectively. The reset assembly is used to push the limiting plate 6 back to the original position when the drawing ruler two 2 is stored back into the drawing ruler one 1, so that the spherical column 7 is always kept in the locking hole 4, thereby stably locking the drawing ruler two 2 and preventing it from accidentally falling off. The connecting assembly comprises a tongue piece 3 fixedly connected on one end of the drawing ruler two 2, and the locking hole 4 is arranged in the tongue piece 3 and embedded with one end of the spherical column 7. When the drawing ruler two 2 is stretched out, the locking hole 4 of the tongue piece 3 and the spherical column 7 are embedded with each other, so that the drawing ruler two 2 is fixed by the mechanical structure, and the drawing ruler two 2 will not be loose or fall off during use. The structure stably fixes the drawing ruler two 2 in the drawing ruler one 1 by the insertion mode when the drawing ruler is stored, achieves the folding and locking effect, effectively avoids the problem that the drawing ruler two 2 is easily separated or shaken during storage, improves the convenience and practicality of the drawing device, and ensures the reliability and safety of the drawing device in daily use.

[0034] Specifically, when stored, one end of the drawing ruler two 2 is connected with one end of the drawing ruler one 1 and achieves smooth folding operation through rotation. Then, the drawing ruler two 2 is inserted into the drawing ruler one 1 through the precisely designed tongue piece 3, and the stable storage function is achieved. In order to ensure the stability after folding, the drawing ruler two 2 and the drawing ruler one 1 are equipped with a precise locking structure, the spherical column 7 in the drawing ruler one 1 can be accurately embedded in the locking hole 4, the movement of the spherical column 7 is effectively limited through the cooperation of the spherical column 7 and the limiting plate 6, and the durability of the locking effect is ensured.
