Fitting, and blackboard support feet is connected with the outside of connector, it is provided with fixed screw, and blackboard on the outside of the blackboard support feet
Book file is installed on the left of support feet, oil pike box, and the centre of blackboard support feet are installed on the right side of the blackboard support feet
Cross-brace is connected with, the lower end of the blackboard support feet is provided with backing plate, and the lower end of backing plate is connected with wheel support, the wheel
The lower end of support is provided with universal wheel.
Preferably, the structure of the blackboard eraser is slide construction, and it is vertically slided up and down.
Preferably, the blackboard eraser is mutually perpendicular to blackboard eraser groove.
Preferably, the hook is arranged to five, and links up with the distance between hook monotonic increase.
Preferably, the blackboard support feet is vertical with book file, and book file is with a vertical 60 ° of inclinations.
Compared with prior art, the beneficial effects of the utility model are：The analytic geometry auxiliary teaching device uses books
The design of folder, oil pike, oil pike box and hook, Book-rest can allow teacher that books are placed on book file when to student's subject of a lecture
On, the left hand of teacher has been liberated, has reduced the amount of labour of teacher, oil pike substitutes chalk, avoids chalk dust and teacher's body is produced
The problem of raw negative effect, the design of book file and oil pike alleviates the work load of teacher, and oil pike box can place oil pike, keep away
Exempt from oil pike loss, reduce certain economic loss, the design of hook facilitates instructors to take drawing instrument, avoids drawing instrument
Place it is mixed and disorderly and to the trouble brought of taking of teacher.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of analytic geometry auxiliary teaching device, including
Blackboard framework 1, blackboard eraser groove 4 and hook 5, blackboard framework 1 is internally connected with blackboard 2, and the front side of blackboard 2 is provided with blackboard eraser
Groove 4, the installed in front of blackboard eraser groove 4 have blackboard eraser 3, and the structure of blackboard eraser 3 is slide construction, and it is vertically upper and lower
Slide, the blackboard eraser 3 that can be slided, facilitate teacher to wipe the vestige that oil pike is drawn or solved a problem on blackboard 2, alleviate teacher
The amount of labour, blackboard eraser 3 is mutually perpendicular to blackboard eraser groove 4, is mutually perpendicular and facilitates teacher when using blackboard eraser 3, one
Secondary property clashes the vestige on blackboard, and the upper end of blackboard framework 1 is mounted with hook 5, and link up with 5 front suspensions have right angle triangle 6,
