Abstract
The utility model provides an angle gauge, includes the angle gauge body, is equipped with the connecting seat at the intermediate position of angle gauge body, articulated on the connecting seat have first ruler, is equipped with the blind groove of T type on first ruler, establishes the second ruler on first ruler, is equipped with the connecting block with the blind groove sliding fit of T type on the second ruler. When the measuring is carried out at the length of wanting the opposite side short angle, through the first ruler on the connecting seat, make one side coincidence of first ruler and measurement angle, first ruler was crossing with the scale on the angle gauge body this moment, alright with the angle of convenient measurement angle of departure, the second ruler can slide on first ruler simultaneously, can draw longer angle limit like this in the painting angle degree.
Description
Technical field
This utility model relates to a kind of protractor.
Background technology
When people need to measure the angle of examination paper in examination when, it usually needs draw extended line, measure with protractor the most again, very inconvenient.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of picture extended line that can need not and measures with regard to the angle that the length of energy opposite side is shorter and can draw the protractor on longer angle limit drawing angle when.
In order to solve above-mentioned technical problem, this utility model includes protractor body, it is provided with connection seat in the centre position of protractor body, connect and be hinged with the first ruler on seat, first ruler is provided with T-shaped blind slot, setting the second ruler on the first ruler, the second ruler is provided with the contiguous block being slidably matched with T-shaped blind slot.When the angle that the length wanting opposite side is shorter measures when, by connecting the first ruler on seat, make the first ruler with measure angle while overlapping, now the first ruler intersects with the scale on protractor body, just the angle of angle of departure can be measured easily, second ruler can slide on the first ruler simultaneously, so can draw longer angle limit drawing angle when.
As further improvement of the utility model, protractor body is provided with lanyard.
In sum, the utility model has the advantages that can need not picture extended line measures with regard to the angle that the length of energy opposite side is shorter and can draw longer angle limit drawing angle when.
Accompanying drawing explanation
It is next with detailed description of the invention below in conjunction with the accompanying drawings that the utility model is described in more detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the attachment structure schematic diagram of the first ruler of the present utility model and the second ruler.
Detailed description of the invention
By shown in Fig. 1 to Fig. 2, this utility model includes protractor body 1, connection seat 2 it is provided with in the centre position of protractor body 1, connect and be hinged with the first ruler 3 on seat 2, first ruler 3 is provided with T-shaped blind slot 4, setting the second ruler 5 on the first ruler 3, the second ruler 5 is provided with the contiguous block 6 being slidably matched with T-shaped blind slot 4, is provided with lanyard 7 on protractor body 1.When the angle that the length wanting opposite side is shorter measures when, by connecting the first ruler 3 on seat 2, make the first ruler 3 with measure angle while overlapping, now the first ruler 3 intersects with the scale on protractor body 1, just the angle of angle of departure can be measured easily, second ruler 5 can slide on the first ruler 3 simultaneously, so can draw longer angle limit drawing angle when.
