Abstract

The utility model discloses a pair of compasses. The compasses comprise a compass head as well as a movable leg and a locating leg, wherein the movable leg and the locating leg are hinged on the compass head; the movable leg comprises an upper movable leg and a lower movable leg, which are integrally hinged with each other; the locating leg comprises an upper locating leg and a lower locating leg, which are integrally hinged with each other; lengths of the upper movable leg and the upper locating leg are as equal as each other; and scales are arranged on both the movable leg and the locating leg. When a ruler is needed in use, the compasses can be used as the ruler through closing the upper movable leg and the upper locating leg and then respectively rotating the lower movable leg and the lower locating leg to the same straight line; moreover, as the scales are arranged on the compasses, convenient drawings can be achieved.

Description

Compasses

Technical field

The utility model relates to a kind of compasses.

Background technology

Often need during student's doing mathematics exercise to draw, compasses and rule drawing tools for using always, two instruments often will be used alternatingly during use, frequent change drawing tools like this, not only losing time also makes the student tired out easily.

Summary of the invention

The technical problem that the utility model will solve provides a kind of compasses that ruler uses that can be used as.

For solving the problems of the technologies described above; The utility model comprises compasses head; With the movable leg and location leg that are hinged on the compasses head; Its design feature is that said movable leg comprises the last movable leg and following movable leg that is articulated as one, and locatees leg and comprises going up the location leg and locating leg, the equal in length of last movable leg and last location leg down of being articulated as one; Said movable leg down is equipped with groove with locating on the leg down.

After adopting said structure; When need using ruler, will go up movable leg, and rotate down movable leg then respectively and locate leg down both are on same the straight line with last location leg closes up; This moment, compasses can work as ruler use, and compasses are provided with groove and can draw very easily.

Description of drawings

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

Fig. 1 is the structural representation of the utility model;

Fig. 2 is a kind of user mode figure of Fig. 1.

The specific embodiment

As depicted in figs. 1 and 2; Compasses comprise compasses head 1; With the movable leg 2 and location leg 3 that are hinged on the compasses head 1; Movable leg 2 comprises the last movable leg 21 and following movable leg 22 that is articulated as one, and locatees leg 3 and comprises the upward location leg 31 that is articulated as one and locate leg 32 down, the equal in length of last movable leg 21 and last location leg 31; Following movable leg 22 is equipped with groove 4 with locating on the leg 32 down.

When need using ruler, will go up movable leg 21 and close up with last location leg 31, and rotate down movable leg 22 then respectively and with location leg 32 down both are on same the straight line, this moment, compasses can work as the ruler use, and compasses are provided with groove 4 and can draw very easily.
