Abstract

A stave rapid line drawing device comprises a handle and a cuboid block internally provided with holes. Chalk is arranged in the holes, springs are arranged at the bottoms of the holes, the top ends of the springs are connected with the bottom end of the chalk, a right blackboard eraser is fixed to the right side of the cuboid block, and a left blackboard eraser is fixed to the left side of the cuboid block. The five holes are formed in the cuboid block, the five holes are arranged at equal intervals, and the interval is not smaller than 1 cm to the minimum and does not exceed 10 cm to the maximum. By means of the stave rapid line drawing device, five lines can be drawn at a time, time and labor are saved, and the speed is high; and in addition, the blackboard erasers are arranged on the left side and the right side of the line drawing device so that mistakenly-drawn lines or mistakenly-written words can be corrected at any time, and great convenience is achieved.
