Abstract
A pair of convenient compasses comprise a compasses seat; a handle is arranged on the compasses seat; a fixed compasses leg and a movable compasses leg are movably connected in the compasses seat; a positioning pin is arranged at the lower end of the fixed compasses leg; a mounting hole is arranged at the lower end of the movable compasses leg; a screw bolt rod is threaded through the mounting hole; a connecting rod is fixedly connected to the right end of the screw bolt rod; the right end of the connecting rod is fixedly connected with a fixed drawing foot; the left end of the screw bolt rod is provided with a locking nut. The rear part of the fixed drawing foot is connected with a movable drawing foot through a bolt and the locking nut. When in use, through adjusting the locking nut, the utility model enables the movable drawing foot and the fixed drawing foot to be opened to form a certain angle and then locked to draw concentric circles. In addition, the movable drawing foot is uplifted, so a single circle can be drawn. The utility model can directly draw concentric circles and is easy to use.
