Descending branch strut.PPT is projected on the transparent projection plate on the left side when in use, it can writing on the blackboard on the writing whiteboard on the right.Most of all,
It can be labeled, and irised wipe using lettering pen counterweight point on emphasis manually on transparent projection plate.
Purpose using transparent projection plate is, can be by the dynamic drawing of transparent projection wrench when having person's handwriting on transparent projection plate
Out, it allows transparent projection plate by cleaning component, transparent projection plate is cleaned；Due to being transparent plate, in cleaning process
Clipboard will not be blocked, does not interfere the writing on the blackboard on student viewing clipboard；The PPT of projection is projected in the projection cloth on partition simultaneously
On, the displaying of PPT will not be interfered.
The projected area of the utility model is associated together with area is write, and teaching process is facilitated flexibly to use, and is thrown in PPT
Shadow part is labeled, and can effectively cause student's note that improving efficiency of teaching.
Sponge can be used in the rub piece of the cleaning component of the utility model, has straight tube in the rub piece of part in cleaning board, can
Cleaning solution is added inside as needed from straight tube upper end toward straight tube, further makes rub piece wet, can preferably clear up transparent
Person's handwriting on projection plate.
The assistance for lifting support rod, lift supporting rod of the utility model are adjusted the height of the utility model, improve this reality
With the novel flexibility used.
Compared with prior art, the utility model has the following beneficial effects:
The utility model structure is simple, easy to use；Assistance for lifting support rod, lift supporting rod, adjustable abridged edition are practical new
The height of type improves the flexibility that the utility model uses；Projected area is associated with by transparent projection plate with writing whiteboard with area is write
Together, facilitate teaching process flexibly to use, and be labeled in PPT projection section, can effectively cause student's note that
Improve efficiency of teaching.
