Abstract

The invention relates to the technical field of learning articles, and discloses a convenient-to-carry and color-changeable mark pen. The mark pen comprises a rotating block, wherein a hanging hole isformed in the front surface of the rotating block. According to the convenient-to-carry and color-changeable mark pen, the rotating block and a screw rod are matched for use, the rotating block drives the screw rod to rotate, and the screw rod drives a moving tube on the outer side to move up and down in a circular tube, so that a pen point and a mounting column are driven to contract in the circular tube; when the mark pen needs to be used for writing, the hand holds the circular tube and rotates the rotating block forward, and the pen point can extend out of the inside of the circular tube;otherwise, the hand rotates the rotating block reversely, the pen point can retract to the inside of the circular tube, the pen point is protected inside the circular tube, and the mark pen cannot bedamaged even if the pen falls off; a magnetic ring and an iron ring are matched for use, and the magnetic force of the magnetic ring is utilized to tightly connect a cap and the circular tube; and the low-falling floor ink is absorbed through the use of a sponge, the outer leakage of the low-falling floor ink is prevented, and the purpose of the mark pen being convenient to carry and use is achieved.
