Disclosed is a thermochromic writing instrument in which an erasing member of the thermochromic writing instrument can be easily separated from a body of the thermochromic writing instrument, and theerasing member is designed to have various cartoon characters, thereby being convenient to use and arousing curiosity and interest of a user, thereby being capable of increasing use fun. A rotating member (60) is inserted into the pen holder (20). The hollow upper cover (30) is separably combined on the outer side of the upper portion of the pen holder (20). The first erasing member (40) is connected to the rotating member (60) through a connecting member (70). A connecting part (52) of the operating member (50) is arranged in a groove (21) formed in one side of the side wall of the pen holder(20), a first body part (51) of the operating member (50) is inserted into the pen holder (20), and a pen clip part (53) of the operating member (50) is exposed out of the pen holder (20).
Description
technical field [0001] The present invention relates to a thermochromic writing instrument, and more specifically, to a thermochromic writing instrument in which an erasing member is easily detached from a body of the thermochromic writing instrument, and the erasing member is used to perform writing on the thermochromic writing instrument. The frictional heat generated during friction causes thermal discoloration of the handwriting and is designed into various cartoon characters, which is not only convenient to use but also arouses the curiosity and interest of users, which can increase the fun of use. Background technique [0002] As we all know, a ball point pen is a modern writing instrument. A ballpoint pen has an ink chamber filled inside with viscous ink. The ballpoint pen replaced the fountain pen as a very cheap and stable, everyday writing instrument that was inexpensive to purchase and use. [0003] Ballpoint pens used with ink refills are widely popular because...
