In Figure 13, Figure 17, Figure 18, Figure 19 and Figure 20: pacify in 40 pearl seat stepped holes 58 in plane 16 on the chi of side
Dress sliding ball 80, using following steps:
First, half 81 in sliding pearl seat is placed on together with half 82 outside sliding pearl seat the low temperature of subzero 125 degree of Celsius temperature
In chest, continue 55 minutes so that size reduction after half 81 and outer half 82 cooling of sliding pearl seat in sliding pearl seat；
2nd, first by slide plate lower plane 61 upward, more successively by half 81 in sliding pearl seat it is arranged in pearl seat stepped hole 58, make
The sliding pearl seat lateral surface 85 obtaining in half 81 in the sliding pearl seat in each pearl seat stepped hole 58 touch stepped hole plane 57, when sliding pearl
When half 81 returns to normal temperature state in seat, slide and have between the sliding pearl seat cylindrical 86 in half 81 in pearl seat and pearl seat stepped hole 58
0.04 to 0.06 interference fit；
3rd, successively sliding ball 80 is placed among circular hole 88 in the sliding pearl seat in half 81 in each sliding pearl seat；
4th, successively outer for sliding pearl seat half 82 is arranged in pearl seat stepped hole 58 so that sliding the cunning in the outer half 82 of pearl seat
Pearl seat faying face 84 touch the sliding pearl seat faying face 84 in half 81 in sliding pearl seat, and sliding ball 80 rides in half in sliding pearl seat
Sliding pearl seat internal taper hole 83 on 81 and the outer half 82 of sliding pearl seat make spacing rolling between sliding pearl seat internal taper hole 83；When outside sliding pearl seat
When half 82 returns to normal temperature state, slide and have 0.04 between the sliding pearl seat cylindrical 86 in the outer half 82 of pearl seat and pearl seat stepped hole 58
To 0.06 interference fit, the sliding pearl seat lateral surface 85 in half 82 outside sliding pearl seat and plane 16 on described side chi maintain an equal level.
When student is carried out with teaching differentiation, step is as follows:
First, in Fig. 9, after the present invention is combined, develop into equilateral triangle, only need to be by the side chi portion in every adjustable rule
Point rotate against with sliding part, by the corner window 31 on slide plate lower plane 61 it was observed that in plane 16 on the chi of side
Corner scale 13 have rotated 30 degree, is drilled by 90 degree of rotations between the inclined plane groove 14 of every adjustable rule itself and inclined-plane protruding rail 41
It is changed into 60, then the scale slope 15 in the first chi part 29 when scale slope 15 and second in chi part 19 and the 3rd side
The angle between scale slope 15 in chi part 39 is all 60 degree, and equilateral triangle is set up.
2nd, Tu10Zhong, develops into isosceles triangle after the present invention is combined, only need to be by the side in wherein two adjustable rules
Chi part and sliding part do the identical anglec of rotation, for example: will be counterclockwise with the 3rd sliding part 38 for the 3rd side chi part 39
Do 15 degree of the anglec of rotation, the second side chi part 29 and the second sliding part 28 are also done counterclockwise 15 degree of the anglec of rotation, then
First side chi part 19 and the first sliding part 18 necessarily do 60 degree of the anglec of rotation counterclockwise, and interior angle is respectively 75 degree and 75
Spend and 30 degree of equilateral triangle is set up.
3rd, Tu11Zhong, develops into right angled triangle after the present invention is combined, only need to be by the side in wherein adjustable rule
Chi part and slipping part divide holding center position not rotate, for example: the second side chi part 29 and the second sliding part 28 are kept
Center position does not rotate, when the 3rd side chi part 39 and the 3rd sliding part 38 do 60 degree of the anglec of rotation counterclockwise, then first
Side chi part 19 and the first sliding part 18 necessarily do 30 degree of the anglec of rotation counterclockwise, interior angle be respectively 90 degree and 30 degree with
And 60 degree right angled triangle set up.
4th, Tu12Zhong, develops into isosceles right triangle after the present invention is combined, only need to be by wherein adjustable rule
Side chi part and slipping part divide holding center position not rotate, in addition the side chi part in two adjustable rules is with sliding part all
The equidirectional anglec of rotation doing 45 degree, for example: the second side chi part 29 and the second sliding part 28 are kept center position not revolve
Turn, the 3rd side chi part 39 and the 3rd sliding part 38 done counterclockwise 45 degree of the anglec of rotation, by the second side chi part 29 and
Second sliding part 28 also does 45 degree of the anglec of rotation counterclockwise, then the isosceles of respectively 90 degree and 45 degree and 45 degree of interior angle are straight
Angle triangle is set up.
The above-mentioned prominent substantive distinguishing features of the present invention, have as follows significantly improve effect:
First, when sliding part is located in chi part one end and is overlapped on, chi partly goes up plane, and slide plate lower plane 61 and side
On chi, plane 16 is in sustained height it is ensured that the length scale 51 on three sides is all in same level, it is to avoid error on line of sight；And every
It is to be slidably matched between the inclined plane groove 14 on inclined-plane protruding rail 41 and adjacent activities chi on adjustable rule, particularly plane on the chi of side
There is corner scale 13 corresponding in position with the corner window 31 on slide plate lower plane 61 on 16, can accomplish convenient, directly perceived
Ground controls the anglec of rotation between sliding part and side chi part；Solid in pearl seat stepped hole 58 particularly in plane 16 on the chi of side
Determine sliding ball 80；The outer prominent sphere 89 of sliding ball 80 contacts with described slide plate lower plane 61 so that each work
On side chi in dynamic plate, plane 16 is more smooth with respect to sliding between the slide plate lower plane 61 in another portable plate easily；Butterfly
Spring outer shroud 115 is fixed on the angle between side chi stepped hole 109 and stepped hole plane 117, and butterfly spring spoke 114 support screw platform
Terrace 112；In conjunction with wing nut 120 adjustment effect it is ensured that plane 16 and the slide plate of itself on side chi in each portable plate
Rotatable in the state of there is frictional resistance between lower plane 61.
2nd, the present invention adopts three one group of portable composite construction, and disassemble afterwards every time, take up room chi by use for convenience
Very little little, be easy to carry.
3rd, education activities chi provided by the present invention, it is simple to have a structure, easy to use, possesses size, angle changeable etc.
Advantage.
4th, the present invention integrally adopts aluminum alloy materials, is electroplate with hard alumel on slide plate lower plane 61, has weight
