Detailed description of the invention
The utility model is elaborated preferred embodiment below in conjunction with accompanying drawing.
A kind of teaching aid of Higher Mathematics Teaching, comprise handwriting pad 1, the edge of described handwriting pad 1 is provided with the cavity 2 of hatch frame, two ends up and down in described cavity 2 are provided with fixed block 3, the corresponding surface of two fixed blocks 3 is provided with slot 4, plate body 5 is provided with in described slot 4, the front surface of described plate body 5 is provided with coordinate line 6, the edge of described handwriting pad 1 is provided with standpipe 13, expansion link 14 is provided with in described standpipe 13, the termination of described expansion link 14 is connected with microphone 16 by universal drive shaft 15, and there is pipe lid 17 on the top of described standpipe 13 by gemel connection.The bottom of described handwriting pad 1 is provided with fixed head 20, the both sides, bottom of described fixed head 20 are provided with jack 21, the hole wall of described jack 21 is provided with screwed hole 22, bolt 23 is provided with in described screwed hole 22, also comprise two sleeve pipes 24, loop bar 25 is provided with in described sleeve pipe 24, the top of described loop bar 25 is arranged in jack 21, the bottom of described sleeve pipe 24 is connected with base 27 by rotating shaft 26, the bottom of described base 27 is provided with runner 28, described sleeve pipe 24 position corresponding with loop bar 25 is provided with fixing hole, is provided with pin 29 in described fixing hole.
Handwriting pad 1 is use of normally attending class, and when upper mathematics class, is pulled out by plate body 5 in cavity 2, can refer to coordinate line 6 so that by the standard of figure, Drawing of Curve during drawing.
One end of expansion link 14 pulls out in standpipe 13, according to the height of the height of teacher adjustable telescopic rod 14 voluntarily, so that to the use of microphone 16, microphone 16 can random adjusting angle by universal drive shaft 15 according to the position of teacher's standing, which, and content teacher said better is passed on away.After using by the retraction of expansion link 14 are microphones 16, universal drive shaft 15 is arranged in standpipe 13, covered by pipe lid 17, prevents the dust of chalk from falling on microphone 16, impact uses.
Loop bar 25 is after sleeve pipe 24 pulls out, be inserted in fixing hole by pin 29, be fixed, the termination of loop bar 25 is inserted in jack 21, by the bolt 23 in screwed hole 22, loop bar 25 is fixed in jack 21, carried out by runner 28, facilitate the viewing of student, after using, can loop bar 25 be retracted in sleeve pipe 24, sleeve pipe 24 is merged by rotating shaft 26 and base 27, and combined and instant, easily carries.
Present embodiment does not just limit its protection domain to the exemplary illustrated of this patent; those skilled in the art can also carry out local to it and change; as long as no the Spirit Essence exceeding this patent, be all considered as the equivalent replacement to this patent, all at the protection domain of this patent.
