Further explanation, when II 4-6 of support rod is with fixing device 4-8 cooperation, and linking up with 4-5 and jack 4-4 cooperation, support rod
II 4-6 and I 4-3 of support rod are on the same line.
The working principle of the invention is：When hanging wall chart using this lectern, cover board 1-5 is opened, then up mobile branch
Fagging 1-4-4, support plate 1-4-4 drive screw rod 1-4-1 and then I 1-4-7 of annulus, II 1-4-8 of annulus are driven to move up, annulus
I 1-4-7 drives two strut 1-4-2 mobile, and strut 1-4-2 drives round bar 1-4-3 to slide in I 1-2 of sliding slot, as strut 1-4-
After 2 is vertical with desktop main body 1-1, hand is unclamped, makes support plate 1-4-4 under gravity around screw rod 1-4-1 and support plate
The hinge of the junction 1-4-4 rotates, and keeps support plate 1-4-4 vertical with screw rod 1-4-1, wall chart is then hung over support plate 1-4-4
It is upper, when needing to adjust the position of support plate 1-4-4, support plate 1-4-4 is pinned with hand, then II 1-4-8 of rotating ring,
II 1-4-8 of annulus drives screw rod 1-4-1 by screw thread, and drives screw rod 1-4-1 mobile, and screw rod 1-4-1 drives support plate 1-
4-4 is mobile, and the position for completing support plate 1-4-4 is adjusted, and facilitates the student viewing of distant place；When studying by oneself in scheduled time, class teacher needs seat to stop
When breath, rotating circular disc 5-2, disk 5-2 drive seat unit 4 to rotate, when the seat plate 4-1 on seat unit 4 is moved to arc panel
At the position gap 5-4-3 on II 5-4, seat plate 4-1 is detached from II 5-4-2 of arc groove, then II 4-6 of rotary supporting rod, support rod I
4-3 makes I 4-3 of support rod, II 4-6 of support rod in same support, then hook 4-5 is inserted into jack 4-4, then around branch
II 4-6 of strut and the hinge of the junction disk 5-2 rotate, and II 4-6 of support rod is made to be moved to the lower end of fixed device 4-8, continue
