On 115 roof.
Supporting mechanism according to Fig.4, the supporting mechanism 12 include the second groove 121, link block 122, damping bullet
Spring 2 123, support lower margin 124, limit hole 1, limit hole 2 126, connecting column 2 127, connecting rope 2 128 and spacer pin two
129, open up the second groove 121 in the bottom end of sliding block 28, be provided with link block 122 in the second groove 121, link block 122 it is upper
Side is provided with damping spring 2 123, the both ends of damping spring 2 123 respectively with 122 roof of 121 roof of the second groove and link block
Welding, wherein offering limit hole 1 and limit hole 2 126 respectively on 121 side wall of the second groove and link block 122;In cunning
The lower end of block 28 is welded with connecting column 2 127, and connecting column 2 127 connects spacer pin 2 129 by connecting rope 2 128;It is connecting
The bottom end of block 122 is also welded with support lower margin 124.
In order to preferably realize the present invention, identical limit hole is all offered on fixed plate 2, sliding block 1 and sliding block 28
13。
In order to preferably realize the present invention, it is welded with connecting column 1 at the both ends of fixed plate 2, connecting column 1 passes through company
Splicing 1 connects spacer pin 1, and spacer pin 1 is inserted into limit hole 13.
Working principle of the present invention: when needing to move computer teaching instrument body 1, starting four simultaneously first
The output shaft driven gear 5 of servo motor 3, servo motor 3 rotates, and since gear 5 is engaged with rack gear 9, gear 5 passes through rack gear 9
It is slided on dragging track 6 with movable slider 1 and sliding block 28 simultaneously respectively;Due to need to computer teaching instrument body 1 into
Row movement, so gear 5 is risen by rack gear 9 with the decline of movable slider 1, band movable slider 28 at this time, when sliding block 1 and sliding block
28 movements when to a certain degree, the walking mechanism 11 of one 7 bottom end of sliding block contact ground, 28 bottom end of sliding block supporting mechanism 12 from
Ground is opened, is then inserted into spacer pin 1 in the limit hole 13 opened up on fixed plate 2, sliding block 1 and sliding block 28, finally
Servo motor 3 is closed, computer teaching instrument body 1 can be moved at this time.
When computer teaching instrument body 1 is moved to required position, need spacer pin 1 from fixed plate 2, sliding block
1 and sliding block 28 on extract in the limit hole 13 that opens up, then start four servo motors 3, the output of servo motor 3 simultaneously
Shaft driven gear 5 rotates, and gear 5 is slided on dragging track 6 with movable slider 1 and sliding block 28 simultaneously respectively by rack gear 9;
Due to needing that computer teaching instrument body 1 is fixed, thus at this time gear 5 by rack gear 9 with movable slider 1 rise,
Band movable slider 28 declines, when sliding block 1 and the movement of sliding block 28 are to a certain degree, the walking mechanism 11 of one 7 bottom end of sliding block from
The contact of supporting mechanism 12 ground for opening ground, 28 bottom end of sliding block, supports lower margin 124 to will drive link block 122 at this time and compresses together
Then spacer pin 2 129 is inserted into limit hole 1 and limit hole two to adapt to the out-of-flatness on ground by damping spring 2 123
In 126, subsequently spacer pin 1 is inserted into the limit hole 13 opened up on fixed plate 2, sliding block 1 and sliding block 28, finally
Close servo motor 3, computer teaching instrument body 1 can be carried out at this time using.
