Embodiment approach

[0028] As an embodiment of the present invention, the end of the first ruler 1 close to the first groove 11 and the end of the second ruler 2 away from the rotating block 12 are both rotatably connected with a first magnet block 43 through a rotating ring 42; The surface of the sliding ruler 41 is provided with a second through groove 44; the side of the second through groove 44 away from the second ruler 2 is provided with evenly arranged tooth grooves 45; Auxiliary gear 46; The surface of the auxiliary gear 46 is provided with a third through groove 47; One end of the sliding ruler 41 away from the first groove 11 is fixedly connected with a second magnet block 48; during work, the first magnet installed on the drawing ruler Block 43 and the second magnet block 48 can effectively make the drawing ruler adsorb on the blackboard surface, and when drawing, the setting of the first magnet block 43 and the second magnet block 48 can make the drawing ruler break away from manual fi...

Abstract

The invention belongs to the technical field of drawing tools, and particularly relates to a drawing ruler for applied mathematics teaching. The drawing ruler comprises a first straight ruler and a second straight ruler; a first groove is formed in one end of the first ruler, one end in the first groove is rotationally connected with a rotating block, the side, adjacent to the first ruler, of therotating block is fixedly connected with the second ruler, and the first ruler and the second ruler are arranged in parallel; the end, far away from the rotating block, of the second ruler is fixedlyconnected with a fixing block, and fixing grooves are formed in the two side walls, adjacent to the second ruler, of the fixing block; and a second groove is formed in the position, right opposite tothe fixing block, of the first ruler, symmetrically-arranged first sliding grooves are formed in the side wall of the second groove, and sliding blocks are connected into the first sliding grooves ina sliding mode. According to the drawing ruler for applied mathematics teaching, by arranging the first straight ruler, the second straight ruler and a sliding ruler, the drawing ruler can be freely combined, by arranging first magnet blocks and a telescopic plate, the drawing ruler has the functions of compasses and a protractor, and the auxiliary effect on teaching is effectively achieved.

Description

technical field [0001] The invention belongs to the technical field of drawing utensils, in particular to a drawing ruler used in applied mathematics teaching. Background technique [0002] Drawing ruler is a general term for a class of tools used to draw graphics. In the prior art, when teachers teach applied mathematics, they often use drawing rulers when teaching because they involve more graphic drawing. However, the drawing rulers in the prior art Rulers can be divided into linear drawing, angle drawing and arc line drawing according to their functions. Since most of the existing tools have a single function and cannot take into account all functions, teachers often need to use multiple tools at the same time when teaching. It is very troublesome when it is beneficial to operate and carry at the same time. [0003] Aiming at the deficiencies of the drawing rulers in the prior art, the Chinese patent has released a mathematics teaching drawing ruler for teaching, the pa...
