Abstract

The invention discloses a crayon with a changeable core. The crayon comprises a screw bottom cover, a barrel and a crayon core. A core fixing nail is arranged in the middle of the inner side of the screw bottom cover. The barrel is composed of five barrel sleeves which are arranged in sequence according to their own sizes and are hexagonal. The outer vertical surface of each barrel sleeve is made of plastic while the inner vertical surface thereof is formed as a rubbing surface. Fixing rings are respectively arranged on the upper side and the lower side of each barrel sleeve. The crayon core is fixed to the screw bottom cover through the crayon core fixing nail and accordingly can be changed optionally according to needs of users and can also be reused. Since the barrel outside the crayon core is composed of the hexagonal barrel sleeves, the crayon can be prevented from slipping. The length of the barrel is controlled by means of extension and retraction of each barrel sleeve through the rubbing surface on the inner wall of the barrel sleeve and the fixing rings on two sides of the barrel sleeve. The crayon core is protected by the barrel.
