The utility model provides a combined teaching aid for mathematics teaching, which includes a telescopic ruler, a rubber plug, a transition fillet, a telescopic spring, a wear-resistant block, a baffle, a sheath body, an extension spring, a sharp corner, a matching fillet, and a sheath body. The scale area and the scale area of the telescopic ruler, the telescopic ruler is installed in the sheath body, the transition fillet is at the upper left end of the sheath body, the rubber plug is installed at the upper end of the excessive fillet and it is always Tangent to the telescopic ruler, there are two telescopic springs in the sheath, the wear-resistant block is installed in the sheath through the telescopic spring, and the baffle is located at the end of the telescopic ruler On the left side of the lower end, the sharp corner is on the right side of the lower part of the telescopic ruler, and the matching rounded corner is on the right side of the upper end of the sheath and can be nested into it by the sharp corner, so that the telescopic ruler and the The right side of the sheath body is on the same vertical line.

Further, the tension spring is installed between the bottom end of the telescopic ruler and the bottom end of the sheath body.

Further, the scale area of the sheath is on the right side of the outer wall of the sheath.

Further, the scale area of the telescopic ruler is on the right side of the wall surface of the telescopic ruler.

Further, the right side of the telescopic ruler forms a trapezoid from the sharp corner.

Due to the adoption of the above-mentioned technology, the utility model has specific positive and beneficial effects compared with the prior art:

1. The utility model can effectively make the two-section scale into a telescopic structure, which is convenient to take.

2. In order to ensure the continuity of the scales of the two scales, the utility model adopts the right side of the telescopic ruler to form a trapezoid from the sharp corner, and the telescopic ruler is nested into the matching rounded corners on the sheath, so that the telescopic ruler and the sheath on the same vertical line.

3. The utility model can not only be used as a scale, but also can replace a telescopic teaching rod.

4. The utility model is simple in structure, safe and reliable, and has a good market prospect.

5. The product of the utility model has good performance and long service life.
