Laser positioning compass

Abstract

The invention discloses a laser positioning compass and belongs to stationeries. The laser positioning compass is structurally characterized in that a laser switch is arranged at the top of a non-slip knob; the lower end of the non-slip knob is connected with the upper end of a transparent window; the lower end of the transparent window is connected with the upper end of a rotary shaft; the rotary shaft is connected to the top of a base; a plurality of foot stands are fixedly connected to the lower part of the base; non-slip foot pads are connected to the bottoms of the foot stands; the non-slip knob, the transparent window, the rotary shaft and the base have the same shaft line; a laser head is positioned on the shaft line and connected onto the lower surface of the base; one end of a beam ruler is connected onto the transparent window; the other end of the beam ruler is vertically connected with a connecting plate; the lower end of the connecting plate is connected with a pen clip; and the pen clip is connected with a writing pen. The laser positioning compass is simple in structure and very convenient to use; the center of a circle can be accurately positioned by laser; the circle can be accurately drawn; a hole cannot be left in a paper sheet; the obtained drawing is beautiful; the circumferential radius can be drawn by the configured ruler; and the circle drawing efficiency is improved.

Description

technical field [0001] The invention relates to a stationery product, in particular to a laser positioning compasses. Background technique [0002] Compass is very commonly used as a tool for drawing and drawing circles. It is not only required to accurately locate the position of the center of the circle, but also to draw a circle that requires a radius. Therefore, the existing compasses generally use a pointed metal foot to locate the center of the circle, and the other supports The writing pen locates the radius of the circle. Before drawing the circle, it is necessary to measure the radius of the circle to be drawn on the ruler in advance. It is very troublesome to use, and when drawing on paper materials, because the sharp metal feet will pierce the paper, it is difficult to Potholes will be left on the smooth paper surface, which seriously affects the beauty of the drawing, and people are easily stabbed by sharp metal feet. It is not safe to use. The current compasses ...

[0002] Compass is very commonly used as a tool for drawing and drawing circles. It is not only required to accurately locate the position of the center of the circle, but also to draw a circle that requires a radius. Therefore, the existing compasses generally use a pointed metal foot to locate the center of the circle, and the other supports The writing pen locates the radius of the circle. Before drawing the circle, it is necessary to measure the radius of the circle to be drawn on the ruler in advance. It is very troublesome to use, and when drawing on paper materials, because the sharp metal feet will pierce the paper, it is difficult to Potholes will be left on the smooth paper surface, which seriously affects the beauty of the drawing, and people are easily stabbed by sharp metal feet. It is not safe to use. The current compasses cannot be used alone. In the engineering manual drawing with high requirements , compass + ruler + drawing board are necessary tools for drawing circles, and it is very troublesome to use. It is necessary to repeatedly locate the radius of the circle on the ruler, which also seriously affects the accuracy of drawing circles.
