The right side of the first threaded column 2 is fixedly connected with a telescopic column 3. When the telescopic column 3 is extended, the teaching pen can be used as a music baton; the upper surface of the chalk cover 1 is fixedly connected with a first connecting block 4, and the upper surface of the first connecting block 4 is fixedly connected with a U-shaped plate 5. The front and rear sides of the inner wall of the U-shaped plate 5 are fixedly connected with a cylinder 6, and the surface of the cylinder 6 and the front and rear sides of the inner wall of the U-shaped plate 5 are both attached to A connecting bracket 7 is provided, a second connecting block 8 is fixedly connected to the upper surface of the chalk cover 1, a first positioning ring 9 is fixedly connected to the right side of the second connecting block 8, an inner wall of the first positioning ring 9 contacts the surface of the connecting bracket 7, a second positioning ring 10 is fixedly connected to the bottom of the inner wall of the U-shaped plate 5, a third connecting block 11 is fixedly connected to the bottom of the chalk cover 1, a nut 12 is fixedly connected to the bottom of the third connecting block 11, a rubber ring 16 is bonded to the inner wall of the chalk cover 1, and the friction between the rubber ring 16 and the chalk prevents the chalk in the chalk cover 1 from slipping out of the chalk cover 1 easily.

[0022] The telescopic column 3 includes a first hollow column 31, the left side of the first hollow column 31 is fixedly connected to the right side of the first threaded column 2, the first hollow column 31 is provided with a first strip hole 32 on both the upper and lower sides, the inner wall of the first hollow column 31 is fitted with a second hollow column 33, and the upper and lower sides of the second hollow column 33 are bonded with a rubber block 34, the surface of the rubber block 34 is in contact with the inner wall of the first strip hole 32, and the friction between the rubber block 34 and the first strip hole 32 makes it difficult for the second hollow column 33 to slide in the first hollow column 31. When the second hollow column 33 is pulled out of the first hollow column 31, the length of the teaching pen increases, and the teaching pen can be used as a music baton.

[0023] The front and rear sides of the connecting column 71 of the connecting bracket 7 are in contact with the inner wall of the U-shaped plate 5, and a second strip hole 72 is opened inside the connecting column 71, and a hollow block 73 is fitted on the inner wall of the second strip hole 72 and the surface of the cylinder 6, and a spring 74 is fixedly connected to the right side of the hollow block 73 and the right side of the inner wall of the second strip hole 72, and a second threaded column 75 is fixedly connected to the right side of the connecting column 71; the connecting column 71 is separated from the first positioning ring 9, and then, the connecting column 71 is rotated to align the connecting column 71 with the second positioning ring 10, and the connecting column 71 is inserted into the second positioning ring 10 through the pulling force of the spring 74 on the connecting column 71, and when the second threaded column 75 on one teaching pen is screwed on the nut 12 on the other teaching pen, the two teaching pens can be fixed together through the cooperation of the second threaded column 75 and the nut 12, so that the teacher can fix multiple teaching pens together.

[0024] A strip ring 13 is fixedly connected to the front of the chalk cover 1, and a first magnetic block 14 is fixedly connected to the inner wall of the strip ring 13 and the front of the chalk cover 1.

The front of the first magnetic block 14 is an N pole, and the back of the second magnetic block 15 is an S pole. When the second magnetic block 15 on another teaching pen is inserted into the strip ring 13 on a teaching pen, the second magnetic block 15 is positioned by the strip ring 13. When the first magnetic block 14 contacts the second magnetic block 15 on the other teaching pen, the two teaching pens can be fixed together by the suction between the first magnetic block 14 and the second magnetic block 15, so that it is more convenient for teachers to carry multiple teaching pens.

[0025] When the teacher uses the teaching pen for art teaching, the chalk can be inserted into the hollow part of the chalk cover 1 from the rubber ring 16 side, and then, the chalk cover 1 prevents the chalk dust from sticking to the teacher's hands when the teacher is drawing; when the teacher uses the teaching pen for music teaching, the second hollow column 33 can be pulled out from the first hollow column 31 to increase the length of the teaching pen and enable the teaching pen to be used as a music baton; when drawing a five-line score, the connecting column 71 is first pulled to separate the connecting column 71 from the first positioning ring 9, and then the connecting column 71 is rotated to align the connecting column 71 with the second positioning ring 10, and the tension of the connecting column 71 by the spring 74 is Insert the connecting column 71 into the second positioning ring 10. At this time, the second threaded column 75 is fixed on the teaching pen in a vertical state through the cooperation of the connecting column 71 and the second positioning ring 10. Moreover, when the nut 12 on another teaching pen is screwed on the second threaded column 75, the connecting column 71 can be used to make a certain distance between two adjacent teaching pens. Then, by fixing multiple teaching pens together, the teacher can draw five straight lines at one time. When the five-line score is drawn, the second threaded column 75 is separated from the nut 12. Then, by inserting the connecting column 71 into the first positioning ring 9, the connecting bracket 7 is fixed on the chalk cover 1 in a horizontal state.
