Abstract
The utility model relates to a novel triangular plate which comprises a plate body and a telescopic ruler. One angle shaft of the plate body is connected with the telescopic ruler, and is provided with a round through hole in the position of the ruler away from the shaft. When in use, the triangular plate and the ruler play respective roles; if a user wants to draw a circle, a pen can be firstly placed inside the through hole at one end of the ruler, and then a known radius circle can be drawn through taking the position of the shaft as the centre of the circle, and rotating the ruler. The utility model has the advantages of simple structure, convenient operation, reasonable configuration and the like, and ensures that the triangular plate have the new functions, thereby conducing to operation.
Description
Technical field the utility model relates to a kind of drawing instrument, especially a kind of new-type set square.
Though the existing set square function of background technology is varied, existing set square function singleness can not satisfy user's needs, for example: existing set square does not have the function of picture circle, the user gets in addition compasses picture circle fully as if thinking the picture circle, and is very inconvenient.
The summary of the invention the purpose of this utility model has overcome above-mentioned said deficiency, and a kind of new-type set square is provided, and is used to solve existing set square function singleness, can not satisfy the problem that people use needs.
For achieving the above object, the new-type set square of the utility model comprises plate body and Expansion ruler, connects Expansion ruler at one jiao of axle of plate body, and is provided with circular through-hole in the abaxial position of ruler.
After adopting said structure, during use, set square and ruler are being brought into play function separately; If want the picture bowlder, pen can be placed on the open-work inside of ruler one end, the center of circle is done in the position of axle, rotation ruler, the known radius of can drawing circle.
The utility model has the advantages that: simple in structure, easy to use, structure has rationally invested the new function of set square, brings greater convenience for people's use.
Description of drawings Fig. 1 is the overall structure schematic diagram of the new-type set square of the utility model.
The specific embodiment as shown in Figure 1, the new-type set square of the utility model comprises plate body 1 and Expansion ruler 2, connects Expansion ruler 2 at one jiao of axle of plate body 1, and is provided with circular through-hole 3 in ruler 2 abaxial positions; Plate body 1 and Expansion ruler 2 are convenient for people to measure straight line and draw the right angle; Drawing bowlder, pen can be placed in the open-work 3, is the center of circle with the position of axle, rotation ruler 2, the circle of the known radius of can drawing.
