Abstract

A compass ruler mainly comprises a right side supporting ruler (1), a left side supporting ruler (2), a scale (3), a screw (4) and a rotating shaft cap (5) and is characterized in that the right side supporting ruler (1) and the left side supporting ruler (2) are connected through the screw (4), the rotating shaft cap (5) is fixedly sleeved at an overlapping position of the right side supporting ruler (1) and the left side supporting ruler (2), and the scale (3) is arranged on the left side supporting ruler (2). Accordingly, the compass ruler not only has a compass function but also serves as a ruler and a dividing rule, and precious mapping is facilitated.

Description

The compasses chi

Technical field

The utility model relates to a kind of compasses chi.

Background technology

General compasses can only be drawn circle, and general ruler can only be measured length, and the student when mapping, often will be ready to compasses simultaneously and ruler could be accomplished the mapping task, loses easily in multiple learning tool is hand held.

Summary of the invention

The purpose of the utility model will solve in the prior art exactly; General compasses can only be drawn circle; General ruler can only be measured length; The student when mapping, often will be ready to compasses simultaneously and ruler could be accomplished the mapping task, and the problem of losing easily in multiple learning tool is hand held provides a kind of compasses chi.

The technical scheme that the utility model adopts is: the compasses chi; Mainly form by right side support chi (1), left side support chi (2), scale (3), screw (4), rotating shaft cap (5); It is characterized in that: the left side is supported chi (2) and is connected through screw (4) with right side support chi (1); Rotating shaft cap (5) fixed cover supports the overlapping of chi (2) and right side support chi (1) in the left side, the left side is supported on the chi (2) has scale (3).

The beneficial effect of the utility model is: the effect that the compasses chi not only can be brought into play compasses also can be used as the use of ruler and rule simultaneously, for accurately mapping convenience is provided.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.

Figure is the structural representation of the utility model.

Among the figure: 1, chi is supported on the right side, and 2, the left side supports chi, 3, scale, 4, screw, 5, the rotating shaft cap.

The specific embodiment

Like figure; The compasses chi; Mainly form by right side support chi (1), left side support chi (2), scale (3), screw (4), rotating shaft cap (5); It is characterized in that: the left side is supported chi (2) and is connected through screw (4) with right side support chi (1), and rotating shaft cap (5) fixed cover supports the overlapping of chi (2) and right side support chi (1) in the left side, and the left side is supported on the chi (2) has scale (3).

The effect that the compasses chi not only can be brought into play compasses also can be used as the use of ruler and rule simultaneously, for accurately mapping convenience is provided.

Claims (1)

1. compasses chi; Mainly form by right side support chi (1), left side support chi (2), scale (3), screw (4), rotating shaft cap (5); It is characterized in that: the left side is supported chi (2) and is connected through screw (4) with right side support chi (1); Rotating shaft cap (5) fixed cover supports the overlapping of chi (2) and right side support chi (1) in the left side, the left side is supported on the chi (2) has scale (3).
