Abstract

The utility model discloses an angle dividing instrument for dividing an angle into three equal parts, which comprises an equally angle-dividing scale, an unfolding rod, a support point, a support vertex, a traction rod, a movable fixation point, a handle, a control handlebar and a fixing point. The equally angle-dividing scale is fixed at the movable fixation point, the movable fixation point is arranged on the handle, the handle is hollow and is movably inserted in the control handlebar, the fixing point is arranged in the control handlebar, one end of the traction rod is fixed through the fixing point, the other end of the traction rod is fixed at the support vertex, the support point is arranged on the equally angle-dividing scale, and the unfolding rod is arranged between the support vertex and the support point. The angle dividing instrument has a simple structure and is convenient to use. The control handlebar is drawn out of the handle, the traction rod is pulled through the fixing point, the equally angle-dividing scale can be unfolded by the traction rod via the unfolding rod, and thus the angle dividing instrument for dividing an angle into three equal parts is formed.

Description

The three equal parts angle divider

Technical field

The utility model relates to a kind of three equal parts angle divider.

Background technology

The carpenter often runs into the situation of picture hisectrix when doing woodwork; When several the student is at the study triangle, also often run into several how problems of picture triangle, calculate pretty troublesome.If there is easy instrument all right.

Summary of the invention

Technical problem to be solved in the utility model is, overcomes the shortcoming that prior art exists, and a kind of three equal parts angle divider is provided, and is simple in structure, reaches purpose easy to use.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of three equal parts angle divider, it is characterized in that, comprise that equal portions divide angle square, strut bar, the strong point, support the summit, draw bar, movable solid point, handle, control handle and fixing point, equal portions divide angle square to be fixed on the movable solid point, movable solid point is located on the handle, handle is a hollow, handle inserts in the control handle versatilely, be provided with fixing point in the control handle, an end of fixing point fixed traction bar, the other end of draw bar are fixed on and support on the summit, equal portions divide angle square to be provided with the strong point, support to be provided with between the summit and the strong point to strut bar.

The beneficial effects of the utility model are: simple in structure, easy to use, control is outwards taking out from handle, and fixing point spurs draw bar, and draw bar divides angle square separately equal portions by strutting bar.

Description of drawings

Fig. 1 is a three equal parts angle divider schematic diagram.

Among the figure:

1 equal portions divide angle square 2 to strut bar 3 strong points

6 handles are put in 5 activities of 4 draw bars admittedly

7 controls are 8 fixing points

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail: the three equal parts angle divider, as shown in the figure, comprise that equal portions divide angle square, strut bar, the strong point, support the summit, draw bar, movable solid point, handle, control handle and fixing point, equal portions divide angle square to be fixed on the movable solid point, movable solid point is located on the handle, handle is a hollow, handle inserts in the control handle versatilely, be provided with fixing point in the control handle, one end of fixing point fixed traction bar, the other end of draw bar is fixed on and supports on the summit, and equal portions divide angle square to be provided with the strong point, supports to be provided with between the summit and the strong point to strut bar.

Of the present utility model simple in structure, easy to use, control is outwards taking out from handle, and fixing point spurs draw bar, and draw bar divides angle square separately equal portions by strutting bar, forms the three equal parts angle divider.
