A tattoo practice device, comprising a coloring portion, a connecting portion, and a sleeve, wherein

• the coloring portion comprises a plurality of coloring rods, wherein each of the plurality of coloring rods is a coloring core configured to apply a color on a drawing medium;
• each of the plurality of coloring rods comprises a non-piercing distal end;
• one end of the connecting portion is connected to the coloring portion, the connecting portion is linked with the coloring portion, and the sleeve is sleeved on a periphery of the connecting portion;
• the connecting portion is configured to move in a first direction along a central axis of the sleeve, so that the coloring cores are close to the drawing medium and color the drawing medium;
• and the connecting portion is configured to move in a second direction opposite to the first direction along the central axis of the sleeve, so that the coloring cores move away from the drawing medium;
• wherein a splitting portion is detachably mounted on the top of the sleeve, and the top of the connecting portion runs through the splitting portion and is arranged above the splitting portion;
• in a state that the splitting portion is mounted on the sleeve, the splitting portion limits a space for an upward movement of the connecting portion, making the connecting portion and the coloring cores fail to be separated from the sleeve;
• and
• in a state that the splitting portion is detached from the sleeve, the splitting portion releases limitation on the upward movement of the connecting portion, enabling the connecting portion and the coloring cores to be separated from the sleeve from the top of the sleeve.
