Spheroid, two the first sleeves is provided with the spherical outside surface of the spheroid, two first sleeves are in the same of the spheroid
On sphere diameter line, the support is assigned into first sleeve, and irregularly-shaped hole is evenly equipped with the spherical outside surface of the spheroid, in two institutes
State and be combined with a receiver between the top of support, the special-shaped block for coordinating the irregularly-shaped hole, institute are provided with the receiver
Interference fits between special-shaped block and the irregularly-shaped hole are stated, more than one opening is provided with the upper half sphere of the spheroid
Groove, the bottom of the receiver are provided with connecting seat, the first screw are combined between the connecting seat and the support.
Preferably, the irregularly-shaped hole includes circular hole and polygonal hole, and the special-shaped block is PVC plastic block, the special-shaped block
Thickness be 2mm-3mm.
Preferably, slipmat is provided with the bottom position of the base, the slipmat is rubber blanket, described anti-skidding
It is glued fixed between pad and the base.
Preferably, the spheroid is plastic sphere, and the wall thickness of the spheroid is 3mm-6mm.
The beneficial effects of the utility model are：The present apparatus uses two spheroids, at school during, can allow two students
Contrast demonstration is carried out, sees that the quantity for the special-shaped block that whose inserts is more unit interval, increases the enthusiasm of student, while also improve
Raw manipulative ability, to deepen memory of the student to geometry, enlivened the atmosphere in classroom, the structure of the present apparatus is relatively simple,
Cost is more cheap, is adapted to promote the use of.
