Abstract

The invention discloses a compass which is simple in structure, convenient to manufacture, and can be used for making drawings easily. The compass comprises a compass head (1), compass legs (2) and a pin (4), wherein the pin (4) is connected with the compass legs (2) by a locking device (3), and the pin (4) can be fixed by the locking device (3) at a position where the angle between the pin (4) and the inner side of the compass legs (2) is from 0 to 180 degrees. The compass has the advantages that the pin can be preferably fixed and hardly slips when a large angle is available between the two compass legs (2).

Description

Compasses
Technical field
The present invention relates to a kind of study article, more precisely relate to a kind of compasses that the pin pin is fixed up of can be good at.
Background technology
At present, sell various compasses on the market, such as the compasses that can be fixed on two compass legs an angle are arranged, the compasses that can change rubber on the compasses head are arranged, the compasses with rule are arranged, but these compasses there are common characteristics, be exactly pin pin and compass leg all be on same straight line, when two compass leg angles were larger, the pin pin was difficult for being fixed up like this, and the pin pin easily skids during picture.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of compasses that easily the pin pin are fixed up under the wide-angle that become at two compass legs are provided.
Compasses of the present invention comprise compasses head, compass leg and pin pin, and described pin pin links to each other by locking device with compass leg, can become 0-180 degree angles to be fixed up by locking device pin pin and compass leg inboard.
Beneficial effect of the present invention is: when (1) two compass leg became wide-angle, the pin pin easily was fixed up; (2) compare with the labyrinth of prior art, this compasses are simple in structure, and cost is lower.
Description of drawings
Fig. 1 is the present invention's two compass legs structure charts when becoming general angle.
Fig. 2 is the present invention's two compass legs structure charts when becoming 180 to spend.
Among the figure: compasses head 1, compass leg 2, locking device 3, pin pin 4.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further described.
In Fig. 1, compasses comprise compasses head 1, compass leg 2, locking device 3 and pin pin 4.
Described pin pin 4 links to each other by locking device 3 with compass leg 2, becomes 0-180 degree angles to be fixed up by locking device 3 pin pins 4 with compass leg 2 inboards.
In the process of using compasses, when two compass legs, 2 angles are larger, to adjust the angle of compass leg 2 and pin pin 4, and be fixed up with locking device 3, pin pin 4 just is difficult for sliding when drawing like this.

Claims (1)

1. compasses, comprise compasses head (1), compass leg (2) and pin pin (4), it is characterized in that, described pin pin (4) links to each other by locking device (3) with compass leg (2), can become 0-180 degree angles to be fixed up by locking device (3) pin pin (4) and compass leg (2) inboard.
