Shell, button shell, button, button spring, pin, pin spring, diving board, axle, pull handle and big spring composition.It is characterized in that：Bottom
Seat and catapult-launching gear pass through being connected of axle and aperture, and the centrage of aperture and macropore is distributed oval bifocal, tiltedly respectively
Face is located at below macropore, takes ball to be located at lower left, and bead projects from catapult-launching gear and falls into macropore, axle through base outer wall reflection
It is welded on catapult-launching gear shell, diving board and pull handle weld and be arranged on the groove of catapult-launching gear shell so that diving board can be in bullet
Injection device inside the shell slide anteroposterior, big spring one end is fixed on the catapult-launching gear enclosure other end and is fixed on diving board, button
Shell is glued to above catapult-launching gear shell, and button inserts button shell in the hole, and button spring one end connects button, and one end connects
Catapult-launching gear shell, little in the hole on pin insertion catapult-launching gear shell, sell spring one end connecting pin, one end connects diving board.
The usefulness of this invention is, by the demonstration of this experimental apparatus, makes principle easy-to-understand；Using bead bounce-back exhibition
Existing experimental phenomena is so as to be easy to observe, and rich interest；Catapult-launching gear design is ingenious, convenient operation；Base is oval nothing
Corner angle, using safety.

Specific embodiment
A kind of ellipse physical characteristics instructional device, be made up of base 1, catapult-launching gear 2 and bead 3, wherein base 1 by
Aperture 101, macropore 102, inclined-plane 103 and take ball 104 to form, wherein catapult-launching gear 2 by catapult-launching gear shell 201, button outside
Shell 202, button 203, button spring 204, pin 205, pin spring 206, diving board 207, axle 208, pull handle 209 and 210 groups of big spring
Become.
Base 1 and catapult-launching gear 2 pass through being connected of axle 208 and aperture 101, the centrage of aperture 101 and macropore 102
It is distributed the bifocal of ellipse respectively, inclined-plane 103 is located at below macropore 102, takes ball 104 to be located at lower left, bead 3 is from ejection dress
Put project in 2 through base 1 outer wall reflection fall into macropore 102, axle 208 is welded on catapult-launching gear shell 201, diving board 207 with draw
Handle 209 welds and is arranged on the groove of catapult-launching gear shell 201 so that diving board 207 can be sliding in front and back in catapult-launching gear shell 201
Dynamic, big spring 210 one end is fixed on the internal other end of catapult-launching gear shell 201 and is fixed on diving board 207, button shell 202 glue
It is connected on above catapult-launching gear shell 201, button 203 inserts button shell 202 in the hole, button spring 204 one end connects button
