Intelligent compasses

Abstract

The invention discloses a pair of intelligent compasses. The pair of intelligent compasses comprises a compasses head (1), a moving leg (2) and a fixed leg (3) and further comprises a battery (9), a switch (10), a controller (8) and a laser transmitter (7), wherein the battery (9), the switch (10), the controller (8) and the laser transmitter (7) are sequentially connected with one another through a wire (11), the battery (9) is used for supplying electric energy, the laser transmitter (7) is located at the bottom of the fixed leg (3), the transmitting head of the laser transmitter (7) is sleeved with one end of a leg pin (6), the leg pin (6) is a straight-through pipe body, a circuit is powered on by pressing the switch (10), the controller (8) drives the laser transmitter (7) to generate laser beams, and the laser beams are illuminated out through the leg pin (6) so that analog drawing of circles or arcs can be achieved. According to the pair of intelligent compasses, the sizes of the circles and the sizes of the arcs can be reasonably simulated and timely adjusted, the radius can also be measured, use efficiency and practicability are improved, and the pair of intelligent compasses can be well used in the measuring and drawing process.

Description

technical field [0001] The invention relates to a compass and belongs to the technical field of measuring and drawing tools. Background technique [0002] A compass is a tool used to draw circles and arcs. It's the lever, and it's the axle. In the actual measurement and drawing process, compasses are often used, so compasses are an indispensable tool for drawing circles or arcs. Existing compasses are made of compass head, movable pin, fixed pin, nib, pin, screw, and movable pin and fixed pin are connected on the compasses head by hinge connection or screw, and the nib is fixed below the movable pin, and the fixed pin is fixed below. Connect the pins, pull the moving pins when drawing, and rotate with the pins of the fixed pins as the fulcrum to realize the drawing of circles or arcs. Such a structure is simple, easy to operate, low in cost, and convenient to draw, but it still has some problems. Such a compass cannot determine the size of the drawing very well, and the ...

Problems solved by technology

Such a structure is simple, easy to operate, low cost, and convenient to draw, but it still has some problems

Such a compass cannot determine the size of the drawing very well, and the drawn arc or circle often exceeds or fails to accurately fall within the specified range, so that the arc or circle drawn by the pen needs to be erased and redrawn, which increases the drawing time. The number of times reduces the efficiency of drawing, and it is impossible to realize analog drawing to determine the size of a circle or arc, and there are limitations

In addition, such a compass cannot measure the radius, and when a circle or arc of a certain radius is required, other scales are needed to draw it, so that it does not have a measurement function, thereby further reducing the practicability of the compass
