Description

technical field [0001] The invention relates to the technical field of teaching aids, in particular to a button-type sucker teaching triangle. Background technique [0002] During the teaching process, when using the triangle ruler, you need to hold it down with one hand and draw the line with the other hand. If there is a slight deviation, the line will not be straight, so you need to be able to fix the triangle ruler on the blackboard. Although some designed triangular ruler fixing devices are simple, they all use direct pulling on the issue of how to desorb after the adsorption is completed. This method is very inconvenient, and if the force is uneven during the pulling process, the suction cup and the The ruler and body are separated. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a button-type sucker teaching triangle that can facilitate the operation of adsorption and desorption. [0004] The techni...
