Abstract
The utility model discloses a convenient angle gauge which is in a semi-circular structure; the middle point of the middle edge is connected with a pointer in a rotating manner, and the top end of the pointer close to the inner side of the angle gauge is an arc section; and one end of the bottom edge of the angle gauge is folded and connected with a straight ruler. The convenient angle gauge has the advantages of reasonable structure, convenience and practicability, complete functions and the like.
Description
Technical field the utility model relates to a kind of study article, especially a kind of measurement drawing instrument.
Background technology is well-known, and people often need the use amount hornwork to measure or draw angle in study and work.But present angle gage structure is too dull, all adopts semicircle transparent panel structure, though the energy measurement angle exists than mistake when drawing angle, makes troubles to people.In addition, also there is the not enough problem of length in the stock on hand hornwork when drawing straight line.
The summary of the invention the purpose of this utility model provides a kind of convenient protractor that possesses the ruler function and be convenient for measuring.
Protractor described in the utility model is the semi-round ring shape structure, and at the base midpoint pointer that is rotationally connected, and the inboard segmental arc of protractor is pressed close on the pointer top; At the folding ruler that connects of protractor base one end.
During use, user normally use amount hornwork takes measurement of an angle.When drawing the angle, the user is at semicircular ring inner rotation pointer, makes angle between pointer and the protractor bottom line equal the angle of required drafting, and along pointer and bottom line drafting lines, the angle of being drawn out is required angle then.When drawing straight line, the user can draw straight line along the protractor base, and also turning expansion ruler is drawn straight line along ruler.
Compared with the prior art, the beneficial effects of the utility model are: rational in infrastructure, convenient and practical, complete function, and can draw angle fast accurately, and be convenient to draw straight line.
Description of drawings Fig. 1 is a stereochemical structure sketch of the present utility model.
The specific embodiment is in stereochemical structure sketch of the present utility model shown in Figure 1, and described protractor 1 is the semi-round ring shape structure, and at the base midpoint pointer 2 that is rotationally connected, and the inboard segmental arc of protractor 1 is pressed close on pointer 2 tops; At the folding ruler 3 that connects of protractor 1 base one end.
