When fruit is still bad, left shadow shield and right shadow shield can be pulled out, and by left connecting seat and right connecting seat rotating around left black
Plate and right blackboard rotate to an angle, and reach optimal shaded effect, and usually the used time can not roll over for left shadow shield and right shadow shield
Close in left blackboard and right blackboard, occupy little space, left blackboard and right blackboard are dual platen, two-sided can be write, increase writing
Area, efficiency of teaching is improved, left blackboard can rotate with right blackboard as leaf through a book around column, easy to operate.The utility model
Reflection prevention blackboard is rational in infrastructure, easy to operate, occupies little space, and counnter attack light effect is good.
2. left connecting seat described in the utility model and right connecting seat cross section respectively with left blackboard and right blackboard side phase
Match somebody with somebody, be easy to left shadow shield smoothly smoothly to be taken out through left blackboard, left connecting seat pull, right shadow shield through right blackboard, right connecting seat
Draw.Hole is threaded on the base, bolt is set in the screwed hole, base is fixed on by correct position by bolt.Institute
State left connecting rod and right connecting rod sets two respectively, the rotation of left blackboard and right blackboard is more stable.The Upper shaft sleeve is with
Axle sleeve bottom sets a ring projection respectively, makes axle sleeve rotation more stable.
