Problems solved by technology

[0002] Geometry in mathematics is a subject that studies geometric figures. In geometry teaching, teachers often need to manually draw geometric figures on the blackboard to facilitate students' intuitive understanding of geometric structures. Since most geometric figures do not have corresponding blackboard writing templates , Teachers' manual drawing is often not standardized enough, resulting in differences between the hand-drawn geometric figures and the expected size and shape, which affects students' understanding
Moreover, the position and angle of the geometric figures drawn manually on the blackboard are relatively fixed. When the same figure with different angles is needed, it is necessary to erase the original one and redraw it, which is very troublesome.

Abstract

The invention discloses a mathematical teaching instrument. The instrument comprises a desk body, a teaching table board and two fixing frames are installed on the upper portion of the desk body, eachfixing frame is in an L shape, the teaching table board is matched with the fixing frames, and a pen container lifting device is installed on one side of the desk body; an intermediate-frequency furnace, a telescopic rod, a second rotating rod and a first pulley are installed on the teaching table board. The intermediate-frequency furnace is used for replacing a common muffle furnace for a university experiment platform, experimental raw materials are more rapid to heat, a relatively high reaction temperature can be achieved only in a short time, and the experiment efficiency is improved. According to the instrument, a transmission rope, the first pulley, a first rotating rod and the second rotating rod are combined to serve as a supporting device of a graphite crucible and an aluminum oxide plate, after heating is completed, only a hanging ring needs to be separated from a positioning column located at the lower part and matched with a positioning column located at the upper part, and the height of the graphite crucible and the height of the aluminum oxide plate can be integrally reduced, so that the graphite crucible is separated from a copper pipe coil, and an experimenter cantake and use the high-temperature graphite crucible more safely, conveniently and quickly.
