Detailed ways

The present invention will be described in detail below in conjunction with the various embodiments shown in the accompanying drawings, but it should be noted that these embodiments do not limit the present invention, and those of ordinary skill in the art can perform functions, methods, or structures according to these embodiments. Equivalent transformation or replacement of the above all belong to the protection scope of the present invention.

Please refer to a specific embodiment of a multifunctional teaching ruler of the present invention shown in FIG. 1 .

In this embodiment, a multifunctional teaching ruler 100 includes: a long ruler body 1, one end of the long ruler body 1 is provided with a protractor 4, the other end is fixed with a first ring member 15, the long ruler The body 1 is provided with a compass 5 close to the end where the protractor 4 is provided, and a thermometer 14 is provided at the end close to the first ring member 15, and a bar magnet 7 is embedded in the center of the elongated ruler body 1 along its length direction. The elongated ruler body 1 is covered with a sliding ruler sleeve 2 capable of sliding along the elongated ruler body 1 . The top of one end of the sliding ruler sleeve 2 is provided with a second annular member 3 , and the top of the other end is provided with a locking screw 6 . The elongated ruler body 1 is rectangular and flat, and can be made of plexiglass.

In this embodiment, the multifunctional teaching ruler 100 further includes: a level 12 disposed on both sides of the bar magnet 7 , and a circular through slot 8 , a square through slot 9 , and a triangular through slot 10 . The level 12 is a closed water column with liquid bubbles 13 , and the circular through groove 8 , the square through groove 9 and the triangular through groove 10 all penetrate the elongated ruler body 1 . A scale 17 is formed on one side of the elongated ruler body 1 , and a straight ruler section 16 and a corrugated ruler section 11 are formed on the other side. The first annular member 15 is close to the wave-shaped ruler section 11 . Slide rule cover 2 is a transparent plastic part. Specifically, the distance from the center of the first ring member 15 to the short side of the long ruler body 1 (the end where the protractor 4 is not provided) is 10 mm. The teacher can check the distance between the center of the second ring member 3 and the center of the first ring member 15 through the slide rule cover 2 and the scale 17 .

In the multifunctional teaching ruler 100 disclosed in this embodiment, a first annular member 15 is provided at one end of the elongated ruler body 1 , and a sliding ruler sleeve 2 with a second annular member 3 is fitted on the elongated ruler body 1 , By inserting the chalk into the first ring member 15 and the second ring member 3, and turning the multifunctional teaching ruler 100 with the center of the first ring member 15 as the origin, insert another piece of chalk into the second ring In the ring member 3 or directly press the first ring member 15 with fingers, and then rotate the elongated ruler body 1 to draw circles or sectors of different sizes.
