[0006] Preferably, a rotating groove is provided on one side of the fixed sleeve, a rotating rod is installed inside the rotating groove, a clamping plate is movably installed on one side of the rotating rod, a sliding groove is provided on one side of the long ruler, a fixing post is fixed on one side of the slider, and a nut is installed on the outside of the fixing post.

[0007] Preferably, the inner diameter of the fixing sleeve is larger than the outer diameter of the chalk, and the fixing sleeve and the chalk form an insertion structure.

[0008] Preferably, the outer side of the rotating rod is provided with an external thread, the inner side of the rotating groove is provided with an internal thread, and the rotating rod and the rotating groove form a threaded connection.

[0009] Preferably, the slider is installed inside the movable groove, and the slider forms a sliding connection inside the movable groove.

[0010] Preferably, the rotating structure includes a fixed plate, a connecting column, and a movable groove. The connecting column is fixed to the top of the ruler, and the top of the connecting column is fixed with the fixed plate. The movable groove is opened inside one side of the ruler.

[0011] Preferably, the movable groove is sleeved on the outside of the connecting column, and the movable groove and the connecting column form a movable connection.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the multifunctional ruler for teaching can be used to draw a circle conveniently through the auxiliary structure, making it easier to draw a circle; and the angle of the ruler can be adjusted through the rotation structure, making it easier to draw different angles.

[0013] 1. With the auxiliary structure, when drawing a circle with a ruler, the combination of the rotating rod and the rotating groove pushes the clamping plate to one side to hold the chalk, thus clamping the chalk. Then, the long ruler is rotated on the ruler to draw a circle. By adjusting the position of the chalk in the moving groove, circles of different sizes can be drawn, making it more convenient to draw circles.

[0014] 2. By incorporating a rotating structure, the long ruler can be rotated on the ruler through the combined use of the connecting column and the movable groove. By adjusting the angle of rotation of the long ruler, different angles can be drawn, making it more convenient to draw angles. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model embodiment provides a multifunctional ruler for teaching, such as... Figures 1-5 As shown, it includes a ruler 1 and a long ruler 2; the long ruler 2 is installed at the top of the ruler 1, and a rotating structure 3 is provided at the connection between the ruler 1 and the long ruler 2; an auxiliary structure 4 is provided inside the long ruler 2.

[0023] In a further preferred embodiment of this utility model, such as Figures 1-5 As shown: The rotating structure 3 includes a fixed plate 301, a connecting column 302 and a movable groove 303. The connecting column 302 is fixed to the top of the ruler 1, and the fixed plate 301 is fixed to the top of the connecting column 302. The movable groove 303 is opened inside one side of the ruler 2 and is sleeved on the outside of the connecting column 302. The movable groove 303 and the connecting column 302 form a movable connection.

[0024] Specifically, when using ruler 1 to draw angles, push the long ruler 2 to one side by hand, so that the movable groove 303 at one end of the long ruler 2 rotates outside the connecting column 302. By adjusting the rotation angle of the long ruler 2 and using the ruler 1, angles of different angles can be drawn, making it more convenient to draw angles.

[0025] In a further preferred embodiment of this utility model, such as Figures 1-5As shown: Auxiliary structure 4 includes a fixed sleeve 401, a sliding groove 402, a piece of chalk 403, a slider 404, a fixed post 405, a nut 406, a moving groove 407, a rotating rod 408, a rotating groove 409, and a clamping plate 4010. The moving groove 407 is opened inside the long ruler 2. The slider 404 is installed inside the moving groove 407. The fixed sleeve 401 is fixed to the top of the slider 404. The chalk 403 is installed inside the fixed sleeve 401. A rotating groove 409 is opened on one side of the fixed sleeve 401. A rotating rod 408 is installed inside the rotating groove 409. One side of the rotating rod 408 is movably mounted...
