Abstract

The invention discloses a portable advanced mathematics teaching mold device, which comprises a frame seat, a teaching mold main body, a protective sheet, a groove, a supporting mechanism and a handle, and is characterized in that the teaching mold main body is embedded in the front part of the frame seat, and the protective sheet is transversely and slidably connected to the front side of the interior of the teaching mold main body. The position of the supporting piece is adjusted on the first sliding base and the second sliding base through the locking bolts, so that the supporting foot assembly moves into the rear side of the frame base, the size of the overall occupied position is reduced, and meanwhile the first rod frame and the second rod frame are driven to be unfolded downwards for supporting or folded for storage through cooperation of the clamping block, the first gear and the second gear by sliding the column rod. And the occupied volume is further reduced, so that carrying is convenient, and the use portability is improved to a certain extent.

Description

technical field [0001] The invention relates to the field related to mathematics teaching, in particular to a convenient and portable advanced mathematics teaching mold device. Background technique [0002] With the rapid development of social economy, the use of teaching molds in the classroom is also gradually increasing. Teaching molds can enable students to intuitively and visually understand the general term of various utensils used in teaching content and the utensils used by teachers in teaching; Teaching aids can improve students' interest in learning, enrich perceptual knowledge, help form clear concepts, and develop students' ability to observe and think. They are generally divided into ordinary teaching aids, special teaching aids, and children's teaching aids. The teaching mold requirements for advanced mathematics are even more demanding. strict. [0003] However, the structure of the prior art advanced mathematics teaching mold device is relatively simple, and...
