Description
Technical field
The utility model relates to a kind of teaching drawing instrument, particularly a kind of multifunction teaching drawing instrument.
Background technology
Traditional teaching drawing instrument has ruler, set square, protractor, compasses etc., and Each performs its own functions for they, and purposes is single.The teacher will get all the complete these teaching drawing instruments of band ready during teaching, uses to be not easy to very much collect and carry.For this reason, also the someone has designed many multifunction teaching drawing instruments, but all there are shortcomings such as complexity, use inconvenience of structure in these multifunction teaching drawing instruments.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of compact conformation, it is multi-functional to have and be convenient to the teaching crutch collecting and carry.
For solving the problems of the technologies described above, the utility model adopts following technical solution: a kind of teaching crutch, comprise straight-bar, cross bar, brace, compasses, one end of cross bar link to each other with the upper end of straight-bar and cross bar and straight-bar perpendicular, the other end of cross bar links to each other with an end of brace, and the other end of brace links to each other with straight-bar, the top form right angle triangle of cross bar, brace and straight-bar, straight-bar is provided with the cavity of collection compasses, and the both feet of compasses are sleeved in the lower cavity of straight-bar after drawing in.
The beneficial effect of the utility model teaching crutch is: in the technique scheme, straight-bar can be used as ruler, the top form right angle triangle of cross bar, brace and straight-bar, compasses are collected in the lower cavity of straight-bar dexterously, make the utility model teaching crutch integrate ruler, set square, compasses function, structure is very compact, very convenient collection and carrying; Various function utensils are very directly perceived in the utility model teaching crutch, need not during use to assemble separately, therefore use very convenient; The utility model teaching crutch can be used as teacher's pointer for the teacher and use, and uses in the time of also can going out blackboard newspaper for the student; The utility model teaching crutch also can be used as crutch, so claim the teaching crutch.
The utility model will be further described below in conjunction with the drawings and specific embodiments.
