Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings.

[0011] Such as figure 1 As shown, the measuring compass pen consists of a pen hole (1), a water-based pen (2), a circle radius scale number (3) and a nib (4). When in use, it can be used as a pen normally. When it needs to be used as a compasses, pull out the pen head (4) from the side and adjust the refill to adjust the radius of the circle radius scale number (3), and read the circle radius scale number (3) directly from the side. The scale can draw a circle.

Abstract

The invention discloses a measuring compass pen. The measuring compass pen is composed of a pen hole, a roller ball pen, radius scale numbers and a pen point and is characterized in that the ball hole is formed at the top of compasses; the roller ball pen is clamped between the compasses in a penetrating mode; the radius scale numbers are arranged on both sides of the part between the compasses; the pen point is arranged at the bottom; the pen hole and the pen point are used for placing and releasing the roller ball pen; the radius scale numbers can be applied to drawing circles; when being extracted from the side surface of the pen point, the roller ball pen can serve as the compasses to measure the radius of circles.

Description

technical field [0001] The invention relates to the technical field of compasses, in particular to a compass that can be used as a ballpoint pen. Background technique [0002] People use compasses in their daily life to measure the radius of a circle, and when measuring the radius of a circle, a ruler is needed to measure the length, which is troublesome, time-consuming, and tool-consuming. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the present invention provides a measuring compass pen, which can be used as a water-based pen for compasses, and can also directly read the size of the radius from the scale on the pen body, without using a ruler to measure the radius first Draw a circle again. [0004] The technical scheme adopted in the present invention is a measuring compasses pen, which is composed of a pen hole, a water-based pen, a circle radius scale number and a nib, and is characterized in that: the pen...
