Background

The writing tool is a tool for writing, through which writing is recorded or written, such as a ball pen, a sign pen, a highlighter, a magic pen, and the like. Among many writing instruments, markers, white pens, fountain pens, mark pens, highlighters, etc. are relatively volatile, and the tips of such writing instruments are exposed to air for a long period of time, and ink in the tips is easily volatilized, resulting in a shortened or damaged writing instrument lifetime. Therefore, the pen point of the book is usually sleeved with a pen cap, so that the pen point is prevented from being contacted with air for a long time. Although the structure can alleviate the problem of ink volatilization, the pen cap is often inserted and pulled out in the using process, so that the pen cap is very troublesome and is easy to lose, thereby bringing inconvenience to users.
