Abstract

The invention discloses a senior high mathematics teaching auxiliary device. The device comprises a connecting piece, a fixing frame, a groove, a first threaded groove and a second threaded groove, wherein a first supporting leg is arranged on the left side of the lower portion of the connecting piece, a second supporting leg is arranged on the right side of the lower portion of the connecting piece, the upper portion of the second supporting leg and the upper portion of the first supporting leg are both connected with the connecting piece through a first threaded rod, the first threaded rod is arranged in the middle of the connecting piece, the rear portion of the second supporting leg and the rear portion of the first supporting leg are both clamped in a first sliding way, the first sliding way is arranged on the front surface of a graduated scale, and the graduated scale is arranged behind the second supporting leg and the first supporting leg. According to the senior high mathematics teaching auxiliary device, the first sliding way and the graduated scale are arranged, when the first supporting leg and the second supporting leg slide in the first sliding way for position adjustment, the positions of the first supporting leg and the second supporting leg can be adjusted according to scales on the graduated scale so as to adjust a radius of a circle drawn through a compass.

Description

technical field [0001] The invention relates to the technical field of high school mathematics appliances, in particular to a high school mathematics teaching auxiliary device. Background technique [0002] When teaching in high school at ordinary times, need to use a lot of teaching aids, wherein the aids of mathematics in high school roughly include triangle ruler, compasses, computer and magnetic strip teaching aid etc., and wherein compasses is one of required utensils when drawing a picture. [0003] Commonly used compasses for high school mathematics are inconvenient to put the tip of the compass into the inside of the legs of the compasses, thus causing the tip of the compass to easily scratch the user when it is taken and carried at ordinary times, which poses a certain safety hazard when used. Contents of the invention [0004] The object of the present invention is to provide a kind of auxiliary device for high school mathematics teaching to solve the problem tha...
