Place is provided with column, and column center is vertically provided with the fixing groove of cylinder, is provided with female thread at the top of fixing groove, from lower on column
On be uniformly provided with cross section for rectangle mounting groove, be equipped with rectangular shaft in mounting groove, in rectangular shaft, be equidistantly provided with fixing hole, fixed
Fix bar being provided with groove, fix bar is cylinder, being provided with external screw thread at the top of fix bar, fix bar passes through each fixing hole by rectangle
Bar is fixed on column, while external screw thread is arranged with screw-internal thread fit fix bar is fixed in the fixing groove on column.
Further, the diameter with diameter greater than ring gear of the driving gear.
Further, swing handle is fixedly connected with through second bearing at the top of the rotating bar.
Compared with prior art, this utility model rotates driving gear by swing handle, while the diameter of driving gear
More than ring gear diameter cause teacher's hand just can obtain on rotating disk in the case where less number of revolutions is paid compared with
Big number of revolutions, is easy to teaching aid to leave ghost, while by changing fix bar through different fixing holes in single rectangular shaft,
Different curves can be obtained in the end of some rectangular shaft, so that different curved surfaces are obtained by rotation, be easy to observation of students,
Student can deepen understanding of the student to curved surface, and this utility model overall structure is simple, easy to use, it is not necessary to power consumption, saves
The energy, is very convenient for during use, and reduces the use of material by the structure of the hollow out of rotating disk, reduces into
This, with preferable promotional value.

Specific embodiment
The technical scheme of this patent is described in more detail with reference to specific embodiment.
Fig. 1-6 are referred to, a kind of higher mathematics curved surface demonstration teaching aid is including base 1, rotating disk 2 and fix bar 6, described
Rotating disk 2 is provided with 1 upper center of base, rotating disk 2 is made up of skeleton annulus 21 and center disk 22, skeleton annulus 21 passes through the six roots of sensation
The connecting rod 23 being uniformly arranged is connected with center disk 22, and 21 outboard array of skeleton annulus is provided with ring gear 24, center disk
