Carry out under the company of middle adult, should not carry and be used for percussion demonstration spheroid 12 to school, carry to school after rifle bolt 3 etc. can be dismantled
Carry out the study of addition pithy formula.Can also a catch be set in toy gun barrel 17, catch is quality of rubber materials, demonstrate spheroid 12
Stopped by catch, even if toy gun barrel 17 is downwards, spheroid also will not drop out toy gun barrel 17, when rifle bolt 3 impact spheroid, spheroid
Catch is pushed to toy gun barrel 17 side and projects muzzle.Further, import, peashooter are offered in the middle part of toy gun barrel 17
Pipe 17 outlet connects import by transparent flexible pipe 6, can again return in trajectory from flexible pipe 6 after spheroid is fired, one
Bullet is repeatedly repeatedly circulated, it is to avoid picks up bullet, nor can injure other people or article.In bullet (spheroid) in toy
In gun barrel 17 and flexible pipe 6 during round and round, because flying speed is exceedingly fast, it is hardly visible the running orbit of bullet, but son can be heard
Bullet reenters the sound that toy gun barrel 17 is clashed into, if arranging a card thorn in the porch of flexible pipe 6, as stated above
Catch, bullet runs at card thorn and can be stopped by card thorn, and flight stops suddenly, now can not only be clearly seen that son
Moreover it is possible to produce infinite entertaining, children can play and must be so fond that will not let out of one's hand the motion state of bullet surely.
The demonstration step of addition is:
1st, the screwdriver 10 screwing out on annulus 11 is standby；
2nd, screwdriver 10 is inserted in a demonstration spheroid fixing hole 13 corresponding to the first storage chamber, with addend numeral 7
As a example the demonstration spheroid fixing hole 13 of downside, the demonstration spheroid another screwdriver 10 being inserted corresponding to the second storage chamber is solid
Determine in hole 13, taking the demonstration spheroid fixing hole 13 of addend numeral 8 downside as a example；
3rd, with hand, left-hand door (iron sheet in the left side) one brush to the left on cover plate is opened, demonstration gun barrel 2 right-hand member is lowerd simultaneously,
Now seven demonstration spheroids 12 in the first storage chamber will enter in the inner chamber of demonstration gun barrel 2 in single file；Equally, with hand by cover plate
On right door (iron sheet on right side) one brush to the right open, simultaneously by demonstration gun barrel 2 right-hand member lower, now eight in the second storage chamber
Individual demonstration spheroid also 12 enters in the inner chamber of demonstration gun barrel 2 in single file, and last sum numeral corresponding to demonstration spheroid 12 is
15；
4th, after the completion of, demonstration gun barrel 2 right-hand member is put height, the demonstration spheroid 12 in demonstration gun barrel 2 will automatically return to drills
Show in first storage chamber and the second storage chamber of bore 1, and close the left and right door on cover plate, can recover to original state again.
Embodiment 2
With reference to Fig. 2, the present embodiment also includes a subtraction movable plate 14, is slidably arranged on demonstration gun barrel 2, demonstrates gun barrel
2 downside is provided with subtraction numeral, and subtraction numeral is gradually increased from left to right, and in each subtraction numeral corresponding demonstration gun barrel 2
Chamber and can only accommodate a demonstration spheroid 12, and subtraction movable plate 14 is provided with the difference display board of a level, difference display board
On be carved with increase successively from right to left a line difference numeral, on the downside of subtraction movable plate 14 left end instruction numeral be minuend,
On the downside of difference numeral (be retained in high order end in demonstration gun barrel 2 and demonstrate the numeral corresponding to spheroid 2), (ball rolls a left adjacent numeral
Walk) it is subtrahend, subtrahend is equal to minuend with difference numeral sum.
The demonstration step of subtraction is:
1st, the demonstration spheroid 12 in all first storage chambers and the second storage chamber is all put in demonstration gun barrel 2；
2nd, subtraction movable plate 14 is moved to the position of minuend, the present embodiment is taking subtraction numeral 14 as a example to be said
Bright, make subtraction numeral 14 be located at the left side of subtraction movable plate 14；
3rd, screw rod is inserted in the subtraction spheroid fixing hole 8 on the right side of a subtrahend, using subtrahend numeral 7 as subtrahend；
4th, gun barrel 2 right-hand member will be demonstrated raise, the demonstration spheroid 12 in screwdriver 10 left side now all can enter the first storage chamber
Or second in storage chamber, the now difference on the subtraction movable plate 14 corresponding to demonstration spheroid 12 of high order end in demonstration gun barrel 2
Numeral as subtracts the difference 7 of rear gained；
5th, after the completion of, then demonstration gun barrel 2 right-hand member is lowerd, the at this moment demonstration spheroid in the first storage chamber and the second storage chamber
12 will be all introduced into demonstrating in gun barrel 2 again, can carry out subtraction study next time again.
