Description

Set square is used in teaching more
Technical field
The utility model relates to a kind of teaching aid, collective's a kind of set square of using of saying so more.
Background technology
The set square function singleness that teaching is generally used is being drawn existing circle, when having angle, parallel lines, vertical line, camber line etc. to compare complicated figure again, just needs that multiple drawing instrument just can finish, and carries with graphing to bother very much.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of simple in structure, easy to operate set square of using is provided more.
To achieve these goals, the utility model is provided with a deep-slotted chip breaker in the middle part of set square, is connected with pointer at the deep-slotted chip breaker circle centre position by pivot pin, and described pointer can freely rotate around pivot pin, be provided with a parallel lines slotted eye on the top of pivot pin, on set square, also be provided with a plurality of circular holes.
By above setting, the utility model can be drawn circle, can draw relatively more complicated figure such as angle, parallel lines, vertical line, camber line again, and it is simple in structure, and is easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, set square 2, deep-slotted chip breaker 3, parallel lines slotted eye 4, circular hole 5, pivot pin 6, pointer
The specific embodiment
As shown in Figure 1, the utility model is provided with a deep-slotted chip breaker 2 in the middle part of set square 1, be connected with pointer 6 at deep-slotted chip breaker 2 circle centre positions by pivot pin 5, and described pointer 6 can freely rotate around pivot pin 5, be provided with a parallel lines slotted eye 3 on the top of pivot pin 5, on set square 1, also be provided with a plurality of circular holes 4.By above setting,,, can measure the number of degrees at angle with deep-slotted chip breaker 2 and pointer 6 with parallel lines slotted eye 3 and pointer 6 can draw straight line, parallel lines, vertical line by a plurality of circular holes 4 can draw diameter different circle and camber line.
