Problems solved by technology

[0003] Since the connecting part of the compasses is a hinge, the hinge is easy to loosen after a long time of use of the compasses. When drawing graphics, misalignment often occurs. Moreover, when the angle between the legs of the two compasses is relatively large, the positioning pin is not easy to fix. The positioning needle is easy to slip, which brings inconvenience to the drawing workers
[0004] And because the existing compasses either can only be used with the drawing pen, or can only be used with the pen core, thus the applicability is low

Abstract

The invention discloses a compass convenient to use. The compass comprises a seat body, a first groove, a driving mechanism, a first gear, a second gear, a first fixing mechanism, a second fixing mechanism, a first supporting leg, a second supporting leg, a positioning pin, a handle, a second groove, a rotating shaft and a rotating disc. The first groove is formed in the lower end of the seat bodyand internally provided with the first gear and the second gear which are connected in an engaged mode; the first supporting leg and the second supporting leg are arranged at the lower ends of the first gear and the second gear correspondingly; the first fixing mechanism which can fix a drawing pen or a pen refill is arranged at the lower end of the first supporting leg; and the second groove andthe rotating shaft penetrating through the second groove are arranged at the lower end of the second supporting leg. Compared with the prior art, the compass can be used conveniently, reliability isgood, applicability is improved, and the positioning pin is conveniently subjected to angle adjustment.

Description

【Technical field】 [0001] The invention relates to the technical field of school supplies, in particular to the technical field of an easy-to-use compass. 【Background technique】 [0002] Compass is a tool used to draw circles and arcs, and it is one of the indispensable tools in our office and study. It is composed of two parts connected by a hinge, and the connecting part in the middle can be adjusted. [0003] Since the connecting part of the compass is a hinge, the hinge is easy to loosen after a long period of use of the compasses. When drawing graphics, misalignment problems often occur, and when the angle between the legs of the two compasses is relatively large, the positioning pin is not easy to fix. The positioning needle is easy to slip, which brings inconvenience to the drawing workers. [0004] Again because existing compass either can only be used with drawing pen, or can only be used with pen core, thereby applicability is lower. 【Content of invention】 [0...
