Abstract
A triangle plate convenient and safe to use comprises a triangle plate provided with three round corners. The side, without ruling, of the triangle plate is a trapezoid edge. Due to adoption of the three round corners of the triangle plate, the triangle plate convenient and safe to use can reduce accidental harm to human body due to the corners of the triangle plate, and increase using safety of the triangle plate; besides, due to adoption of the trapezoid edge of the side without the ruling, the triangle plate convenient and safe to use enables a user to take the triangle plate from the table easily and improve using convenience of the triangle plate.
Description
Technical field
The utility model belongs to office, study article field, is specifically related to a kind of set square, relates in particular to a kind of set square easy to use, safe.
Background technology
Now, in people's work, studying and living, set square is one of main drawing tool of immunologing mathematics, measuring angle, and it has broad-spectrum characteristics.
Three angles of set square often are designed to the shape of wedge angle, and people in use easily are wounded by stabbing, and very large security incident easily occurs if set square is used as toy by children, have so the large problem of potential safety hazard; Simultaneously, the edge on each limit of set square is designed to the right angle trigonometry shape, so set square is placed on and is easy on desk fit tightly with desktop, thereby makes the user be difficult to pick up, and has like this inconvenient problem with use.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and the set square a kind of easy to use, safe that provides, it can solve the problem of the easy scathing of set square wedge angle well, and can solve set square and put and be difficult on the table the problem picked up.
The purpose of this utility model is achieved in that
A kind of set square easy to use, safe comprises set square, and three angles of set square are fillet, and set square is trapezoidal shape without the edge of the side of scale.
Above-mentioned set square is the isosceles trapezoid shape without the edge of the side of scale.
On above-mentioned set square, the edge of graduated side is the right angle trigonometry shape.
The material of above-mentioned set square is plastics or metal.
The utility model has been obtained following technique effect:
At first the utility model has adopted the structure that three angles is made as fillet, the angle that can reduce set square in thorn unintentionally during the people to the injury of human body, strengthened the safety in utilization of set square; Secondly, its edge without the side of scale has adopted trapezoidal structure, makes the user to pick up set square from desktop at an easy rate, has improved the ease of use of set square.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that Fig. 1 is without the structure chart of the marginal portion of the side of scale;
Fig. 3 is the structure chart of the marginal portion of the graduated side of Fig. 1.
The specific embodiment
A kind of set square easy to use, safe, comprise set square 1 as shown in Figure 1, and three angles of set square 1 are fillet.
As shown in Figure 2, set square 1 is trapezoidal shape without the edge 2 of the side of scale.Set square 1 also can be the isosceles trapezoid shape without the edge 2 of the side of scale.
As shown in Figure 3, on set square 1, the edge 3 of graduated side is the right angle trigonometry shape, and a graduated like this side can fit tightly with the position that needs are measured.
The material of set square 1 is plastics or metal.
When adopting said structure, set square in use not only can be easy to, be picked up from desktop by the side without scale by the user easily, and its three angles structure that is fillet can greatly reduce set square in thorn unintentionally during the people to the injury of human body.
